Factors to Consider

Before diving into specific roofing materials, it’s important to consider several key factors that influence the best roofing choice for a commercial building:

Building Structure and Design

The structure and design of the building play a significant role in determining the suitable roofing material. Flat roofs, sloped roofs, and unique architectural features each have different requirements.

Climate and Weather Conditions

Local climate and weather conditions impact the performance and longevity of roofing materials. Areas with heavy rainfall, snow, high winds, or extreme heat require materials that can withstand these elements.

Energy Efficiency

Energy efficiency is a crucial consideration for commercial buildings. Roofing materials with high reflectivity and insulation properties can help reduce heating and cooling costs, making the building more energy-efficient.

Budget and Lifespan

The budget for roofing installation and maintenance, as well as the expected lifespan of the roofing material, are important financial considerations. It’s essential to balance initial costs with long-term benefits.

Popular Commercial Roofing Options

Several roofing materials are commonly used for commercial buildings, each with its own set of benefits and drawbacks.

Built-Up Roofing (BUR)

Built-up roofing (BUR) is one of the oldest and most reliable commercial roofing systems. It consists of multiple layers of bitumen (asphalt) and reinforcing fabrics, topped with a layer of gravel or mineral granules.

Advantages

• Durability: BUR systems are highly durable and can last 20 to 30 years with proper maintenance.
• Weather Resistant: The multiple layers provide excellent protection against weather elements.
• Low Maintenance: Requires minimal maintenance over its lifespan.

Disadvantages

• Installation Time: BUR systems can be time-consuming and labor-intensive to install.
• Weight: The multiple layers add significant weight to the building structure, which may require additional support.

Modified Bitumen Roofing

Modified bitumen roofing is a variation of BUR that incorporates polymer-modified bitumen membranes. It offers similar benefits with enhanced flexibility and ease of installation.

Advantages

• Flexibility: The added polymers improve the material’s flexibility, making it less prone to cracking.
• Easy Installation: Modified bitumen can be installed using various methods, including torch-applied, cold-applied, and self-adhering membranes.
• UV Resistant: Often comes with a reflective surface that improves UV resistance and energy efficiency.

Disadvantages

• Cost: Can be more expensive than traditional BUR systems.
• Vulnerability to Punctures: Although durable, it can be vulnerable to punctures from sharp objects or heavy foot traffic.

Thermoplastic Olefin (TPO)

Thermoplastic olefin (TPO) roofing is a single-ply membrane known for its energy efficiency and ease of installation. It is one of the fastest-growing commercial roofing systems.

Advantages

• Energy Efficiency: TPO membranes are highly reflective, reducing cooling costs by reflecting UV rays.
• Cost-Effective: Generally more affordable than other single-ply membranes like PVC.
• Durability: Resistant to tears, punctures, and impact damage.

Disadvantages

• Quality Variability: The quality of TPO can vary significantly between manufacturers, affecting performance and lifespan.
• Limited Color Options: TPO membranes are typically available in white, limiting aesthetic choices.

Ethylene Propylene Diene Monomer (EPDM)

Ethylene propylene diene monomer (EPDM) is a synthetic rubber roofing membrane widely used for flat and low-slope roofs.

Advantages

• Durability: Known for its exceptional durability and longevity, often exceeding 30 years.
• Weather Resistant: Excellent resistance to UV radiation, ozone, and extreme temperatures.
• Ease of Repair: Easy to repair and maintain, with a wide range of compatible repair materials.

Disadvantages

• Color Absorption: Typically available in black, which can absorb heat and increase cooling costs.
• Chemical Sensitivity: Vulnerable to damage from certain chemicals and solvents.

Metal Roofing

Metal roofing is a popular choice for commercial buildings due to its durability, longevity, and modern appearance. Common metals used include steel, aluminum, copper, and zinc.

Advantages

• Longevity: Metal roofs can last 40 to 70 years with proper maintenance.
• Energy Efficiency: Reflective coatings can reduce cooling costs by reflecting solar heat.
• Fire Resistant: Metal roofs are non-combustible and provide excellent fire resistance.

Disadvantages

• Cost: Higher initial cost compared to other roofing materials.
• Noise: Can be noisier during rain or hail unless properly insulated.

Green Roofing

Green roofing systems, also known as vegetative or eco-roofs, consist of a waterproof membrane covered with soil and vegetation.

Advantages

• Environmental Benefits: Improve air quality, reduce urban heat islands, and promote biodiversity.
• Energy Efficiency: Provide natural insulation, reducing heating and cooling costs.
• Stormwater Management: Absorb rainwater, reducing runoff and mitigating flooding.

Disadvantages

• Weight: Green roofs are heavy and may require structural reinforcement.
• Maintenance: Require regular maintenance to ensure the health of the vegetation and integrity of the roofing system.

Wood Shingles or Shakes

Wood shingles offer a rustic, natural look that complements many architectural styles. Because of wood’s insulative properties, wooden roofing can help regulate indoor temperatures. If sourced responsibly, wood shingles can be an environmentally friendly option.

Despite its benefits, there are a few drawbacks to consider when thinking about installing a wooden roof in Louisville and Chattanooga, TN. For starters, wood shingles require regular maintenance, including sealing, staining, and occasional replacement. Because wood is flammable, wooden shingles may pose a fire hazard in areas prone to wildfires or with strict building codes. They are also more expensive than traditional asphalt shingles. 

Clay or Concrete Tiles

Clay and concrete tiles are prized for their longevity and can last 50-100 years or more with proper maintenance. Tiles offer a distinctive, elegant look that enhances the curb appeal of a home. Furthermore, they are fire-resistant, making them a great option for areas prone to wildfires. 

Nevertheless, clay and concrete tiles do have some negatives — namely their weight. Oftentimes, additional structural support is necessary to withstand the weight of the roof. These roofing options are also a lot more expensive than others. And despite their longevity, clay tiles in particular are fragile and can crack if walked on or impacted by a tree branch or large hailstones.

What is green roofing and what are the benefits? 

Green roofing is sometimes referred to as a living roof or a vegetated roof. They are installed on a ballasted roof with a waterproofing membrane. Once the membrane is in place, the soil and plants are then installed.  Well-designed and well-engineered green roofing that is consistently maintained can provide several benefits such as: 

• Environmental
• Social
• Economic 
• Aesthetics

Results of research and studies provide us with more details on these benefits: 

• Stormwater Management: There are massive amounts of concrete and paved surfaces in suburban and urban areas which can cause problems, like not allowing stormwater to be absorbed into the earth’s natural surface. This results in excessive amounts of runoff water causing damage and sweeping pollutants into the water bodies. Green roofing reduces that stormwater flow by over 60% and delays the flow rate by 3 hours.
• Energy: Green roofing reduces the energy needed to cool structures by providing shade, insulation, and thermal mass.
• Biodiversity and Habitats: Green roofing provides new urban habitat for birds, insects, and plants which increases biodiversity.
• Urban Heat Island: If you’ve gone from the city to the country, you’ve noticed the air is typically warmer. This is because these asphalt and concrete surfaces absorb solar radiation. That leads to more energy consumed to cool homes and businesses. Green roofing helps reduce this Urban Heat Island effect.
• Lifespan of Roofs: Green roofing has a lifespan that is two times longer than conventional and traditional roofing.
• Aesthetically: Green roofing adds beauty to a flat roof structure, which adds value to the structure too.

What does green roofing installation cost?

This can depend on which type of green roofing you choose to have installed. The general price range of the 4 different types, based on 1,000 square feet and includes the materials are:
Semi-intensive Green Roofing: Between $15,000 and $35,000
Extensive Green Roofing: Between $10,000 and $25,000
Blue-Green Roofing: Between $13,000 and $35,000
Bi-solar Green Roofing: Between $25,000 and $40,000

What are the differences in these 4 types of green roofing?

Any of these four green roofing options is a help to the environment in its way. The differences in these roofing options are:

• Semi-intensive green roofing is typically six to ten inches deep and is lighter and shallower than an intensive roof. It has a higher level of maintenance than extensive green roofing, but less than intensive green roofing. It can support a wider selection and more plant life than extensive green roofing. 
• Extensive green roofing is more affordable with a soil layer between four inches and seven inches. Ideal for a flat or low-sloping roof with shallow root vegetation. Minimal maintenance is required with extensive green roofing. 
• Blue Green roofing incorporates stormwater collection and management (the blue part) and a garden (the green part), giving the structure energy and water efficiency. 
• Bi-solar Green Roofing is a combination of vegetation and solar panels. This eases the Urban Heat Island effect and helps the building create clean electricity.   

Are there any drawbacks to green roofing?

Green roofing has several advantages, and they are important to our climate and environment. But yes, there are drawbacks to green roofing too: 

1. A higher cost 

Green roofing is, unfortunately, more expensive to install than the standard roofing options. Contributing to that higher cost is the extra support that is needed to handle the increased load.  While this may give you sticker shock initially, the ROI will come over time in lower utility bills. 

2. Increased weight load 

As mentioned above,  the higher cost is attributed to the additional support because of the additional weight of green roofing. Green roofing can increase the weight up to 110 pounds per square foot. A structural engineer inspection should be done before having green roofing installed to ensure the structure can handle the weight even with extra support. 

3. Extra maintenance

Green roofing will require some work to ensure it is thriving and doing the job you have in mind. Green roofing will require a routine of feeding, watering, and weeding. For a commercial structure, dividing these tasks between the occupants can make light the work! 

At The Root of The Matter: Is Green Roofing Worthwhile? 

Just as with your own home, the benefits of green roofing on a commercial structure are quite significant. They not only help minimize the urban island heat issue, but green roofing can help lower energy use, which will lower your energy bills. It also helps extend the lifespan of the existing roof surface, which is money saved by eliminating having to replace the roofing. 

Can solar roofing power a commercial building?

Absolutely! The square footage of a commercial structure makes it ideal for a solar roofing installation. With solar panels properly installed and positioned, they can generate ample power for a commercial structure’s energy consumption.

Is solar roofing for commercial buildings different from solar roofing for residential structures?

The technology used for both commercial and residential solar roofing is the same, but there are some differences in the way it is used including: 

• The Size:  Commercial solar roofing panels are heavier and larger. 
• The Wattage: Commercial building solar roofing is made to meet the higher energy requirements.
• The Mounting: Commercial and residential structures have different types of architecture. Commercial structures typically have flat roofing which requires additional equipment for mounting the solar roofing panels. This additional mounting equipment allows the panels to tilt for optimum energy absorption. 
• The Installation: Solar roofing installation requires more labor and time because the panels are heavier and larger. 
• The Cost: Installation for residential solar roofing is less expensive than for commercial structures. Both commercial and residential have rebates tax credits.
• The Regulatory: Commercial solar roofing installations may be subjected to regulations and permits that residential properties don’t. 

What size is commercial solar roofing available in? 

The average commercial solar roofing panel is 78” by 39” with 72 cells and can produce up to 400 watts, making them ideal for large-scale solar installations. Other choices in solar roofing panels for commercial properties include: 

• 60 cells installed in a 6 x 10 grid
• 72 cells installed in a 6 x 12 grid
• 96 cells installed in an 8 x 12 grid

How is the size of a commercial solar roofing system determined? 

A professional solar roofing contractor will help you determine the size of solar roofing panels needed. This is done by taking the daily kWh energy requirement and dividing it by the hours of peak hours of the sun to determine the kW output. Then the kW output is divided by the solar roofing panel’s efficiency to determine an estimation of the solar panels needed.

What are the disadvantages of solar roofing for commercial structures?

There are several advantages for a business or commercial structure to invest in a solar roofing installation. Among those advantages are: 

• Money Saver: Energy cost savings are a key advantage to commercial solar roofing installation, but there are several other incentives offered to a business that switches to solar power. Those incentives can help offset the initial expense of installation like MACRS (Modified Accelerated Cost Recovery System), which can be claimed for up to 5 years.
• Going Green: By switching to solar roofing energy, a business can reduce its carbon footprint significantly, a bonus to overall environmental impact. 
• Minimal Maintenance: Solar roofing systems require little to no maintenance. The primary concerns are keeping them clean so the UV rays from the sun aren’t blocked or minimized. 

But with these significant advantages, there are some disadvantages to commercial solar roofing panel installation. Among them are: 

• Upgrades to the roofing system
• Upfront installation is expensive (including the roofing upgrade)
• It is weather Dependent (as more sunshine equals more energy)
• Incentives and requirements change every year

Is a larger solar roofing system better? 

Larger isn’t better in all instances, but when it comes to solar roofing, having an oversized solar roofing panel system can only produce more energy. What isn’t used is stored, and in many areas, the business may get paid for excess created energy through PV Demand Credit.

Why don’t more commercial buildings have solar panels?

There are two main reasons that more commercial structure owners haven’t invested in solar roofing systems, with cost being the number one reason. Over time, there is a reduction in energy costs that can offset the initial expense. But that initial expense is an expense that many businesses can’t spare. 

The next concern is reliability with the intermittent pattern of solar power. When the sun is out and strong, more energy is stored, but there are times when there is less sun, such as rainy days. The peak power production doesn’t always align with the demands of a business, especially a business that operates 24 hours. Because solar roofing power isn’t consistent, many businesses can’t depend entirely on solar power.

The Bottom Line

As a business owner, will it be worthwhile to invest in solar roofing? Yes, it is just a matter of patience for the solar roofing panels to build up the energy. The more solar tiles you have installed, the more savings you’ll see. This can vary between forty and sixty percent over a year. However, if you’re interested in solar roofing in Knoxville, Tennessee, our team can walk you through your options.

What are the most common types of residential roof insulation? 

There are different types of residential roof insulation, among the common ones are: 

• Fiberglass
• Cellulose
• Spray Foam

Each of these has its own benefits and each has its own downsides. What are the benefits of these three types of roof insulation? Read on for information: 

Fiberglass Roof Insulation: 

There are tiny pieces of recycled glass that are melted down and combined with limestone, sand, and other materials. The cotton-like appearance comes from this substance being woven into long strands. Fiberglass roof insulation comes in three forms: 

• Batts

These are the large rolled-up sheets you see at your local home improvement stores. Aluminum is used to hold the batts together. This is an easy and quick way for roof insulation If is easy to fit between standard roof joists but can be challenging to customize around pipes and odd-sized roof joists. 

• Loose-fill 

Similar to batts, this type is also made from recycled glass but is blown into the attic with a special machine. The advantage of this type of insulation, it gets in and around those hard-to-fit places that the batts can’t. 

Cellulose Roof Insulation: 

This roof insulation is clumpy, dense, and thick, with a down feather-like consistency. In this shape and size, it fits well in enclosed areas like inside walls and conforms around obstructions in the attic and walls. 

The loose-fill type of cellulose roof insulation is a dry material, as it is blown into the areas needed. Some benefits of this type of roof insulation: 

• It settles and conforms around obstructions.
• A relatively inexpensive roof insulation with an R-value of 3.5 per inch of thickness. 
• Easier to install in finished walls than batts.
• Fairly insect and vermin resistant. 

Spray Foam Roof Insulation

Spray foam roof insulation has the highest R-value in roof insulation, delivering air, moisture, and thermal barriers. During the summer months, it keeps the heat out and during the winter, it keeps the heat inside. 

What type of insulation is best for my home? 

When the budget is a concern, the batt type of roof insulation is better than nothing! Where budget isn’t an issue closed-cell foam roof insulation is the most effective with an R-Value of 6.2 per inch. 

Can I insulate my roof myself, or do I need a professional? 

Because roof insulation is made from particles of glass, it can be highly irritating to the skin. Professional roof insulation is recommended because they have the equipment and gear to protect their eyes, skin, and most of all, their breathing. 

How often should I inspect my roof insulation? 

An annual inspection of your roof insulation is recommended.  Additional times for roof inspection would be if you have any roof damage that requires roof repairs or replacement. 

What are the signs of failing roof insulation? 

Yes, your roof insulation can become less effective over time, usually because of moisture in the attic. If moisture comes in contact with roof insulation, it weakens the integrity, mold forms, and the fibers break down. 

1. Higher Energy Bills

If your energy bills are increasing more than they normally do during the summer or winter, you should have your roof insulation inspected. 

2. Temperature Constantly Fluctuates

Poor roof insulation makes the HVAC system work harder, but it isn’t keeping the rooms consistently comfortable.  

3. Freezing Pipes

Winters in Tennessee get cold and poor roof insulation can expose the plumbing to extreme temperatures, resulting in busted pipes. 

4. Condensation In the House 

Warm air is moist with water and when it reaches a cold surface, the heat vapor turns back to the water, like when you get out of the shower and the mirror fogs. 

5. Rodent and Pests Infestation

If pests and rodents get into the insulation, they’ll nest, leaving their feces and disease behind to spread throughout your house.  

6. Roof Top Ice Dams 

When the roof insulation isn’t sufficient in the attic, heat escapes, and melts the ice and snow during the day. Then as temperatures drop at night, that refreezes because the water can’t run off, forming an ice dam. 

7. Drafts 

If your home seems to be drafty, you should have the roof insulation inspected and consider upgrading your windows. 

8. Water Dripping from the Attic

Water dripping from the attic could be because of poor roof insulation or a roof leak, which will damage the roof insulation. 

To Top Off Your Home

In addition to the unseen things like the sewer line and water heater, the roof insulation is unseen and often underappreciated, but all are very much important.  If you haven’t had a new roof installed recently, getting an inspection of your roof insulation may be a money saver down the road! You can reach us at 865-238-2628 to schedule a personalized consultation regarding your roof insulation in Louisville and Chattanooga, TN.

How do solar panels reduce electricity usage?

After that initial expense, solar panel roofing acquires the sun’s energy and turns it into energy that you can use in your home – for free!  These panels installed on the roof are generating power to run your air conditioning, watch television, use your computer, hair dryer, and all things electrical. 

Not only are minimizing how much that electric meter on the side of your house is spinning, but you are also building up more electrical power to use the next day, and you’re making energy that you can sell back to the power company! 

How does solar power reduce your electricity bill?

It is that upfront expense of having solar panel roofing installed that makes homeowners wary of joining the solar power movement. But this is one home improvement project that will give your home ongoing, long-term energy efficiency. There are other benefits of solar panels to be enjoyed too, so let’s recap those benefits: 

Saving Money

We have stated this already, but worth stating it over again, having solar panel roofing installed saves you money on utilities. Many homeowners say they have seen a 50% drop in their electric bill, because their home is getting powered by the sun through their solar panels. What happens those cloudy days or at night though? Your home is still hooked up to the local power grid and that is the only power you’ll pay for. 

No Maintenance 

With solar panel roofing, there aren’t those unexpected issues and expenses that occur when you’re on the electrical power grid. Solar panels come with extensive warranties and when there is a problem, they take ownership and make any needed repairs. When there is an issue with the electric company that causes you damage, the utility companies do not take any ownership other than getting the power restored. 

Tax Credit

The government encourages us to go with solar panel roofing and in many areas, homeowners are given tax credits for having this environmentally conscious home improvement installed. Some local municipalities will give you tax credit and the federal gives tax credit too.  

Electric Power Costs

You’ve already noticed that your electrical bill is higher now than it was this time last year. And it will continue to increase every year, even if just a fraction of a penny per KWh, it will increase, just as natural gas and other means of power – except solar power! With solar panel roofing, your monthly expenses will not increase! 

Do solar panels power your house?

Any homeowner that is considering solar panel roofing will always ask, “Is solar power energy really able to power my entire house?” And solar panel roofing experts will reassure them, yes, your entire home can be powered by having solar panel roofing installed! 

However, there are some variances that need to be taken into consideration, like power output levels of the panels and how many solar panels your home need for your family’s energy use. Any solar panel roofing expert will review these things with you, ask questions about your electrical uses, and then make recommendations for the number of panels and the placement of the panels. 

No two homes are exact in their energy use, so the number of panels installed will be different. The placement and the angle of the panels will vary too so that you’re getting the most benefit from the sun’s energy possible. 

Do solar panels reduce the heat load on a roof?

The numbers vary from house to house, city to city, state to state, but most homeowners that have gone with a solar panel roofing install have found their roof is cooler by as much as 5 degrees, some even more. The solar panels are absorbing the sun’s UV rays before they get to the roof, so the roof isn’t getting heated up. Think of solar panel roofing as an umbrella for your roof! 

How many solar panels are needed to run a house?

Again, no two homes are the same, so the number of panels needed to give you the most benefit of the sun’s energy can be different than your neighbors. On average, 1500 square foot home typically needs between 15 and 20 solar panels. This isn’t a standard rule, just an average.  Your home may need more. Your home may need less. Your solar panel roofing expert will review this with you during the initial interview. 

What is the lifespan of a solar panel?

Solar panel roofing has been manufactured since the 1980s, and the ones that are still installed, are still powering up homes! So, you can expect your solar panel roofing, aka photovoltaic panels, to power your home for over 25 years! 

Today, there are so many choices in roofing systems for a home, here are the most common and popular choices: 

Asphalt Shingle Roofing Systems

Without a doubt, asphalt shingles are the most common roofing systems in the country. It’s an economical way to top your home that is easy to install, comes in a range of colors and styles, can withstand the blistering hot and frigid cold weather, and will last up to 20 years or longer. The different grades of asphalt shingles available, some can last up to 30 years. 

Ceramic Tile Roofing Systems

Of all the roofing systems available, this one gives a home character with the long-lasting durability of 70 years. Fade and fire-resistant, this roofing material is not the best where the weather fluctuates though, or where there are high wind conditions.  

Slate Roofing Systems

Give your home a sophisticated and upscale look with slate roofing systems. A fire-resistant, rot-resistant, all-natural look that can last 100 years or longer. Available in multitudes of colors and styles but also at a high cost, which makes it one of the least chosen types of roofing systems. 

Wood Shakes and Cedar Shingle Roofing Systems

Cedar shake roofing systems are reliable in any climate, especially in hot and sunny climates because of their resistance to UV rays. They are durable in harsh weather like hurricanes and thunderstorms and provide natural energy-saving quality.   Upgrade for fire-resistant coating is available.  

Wood shake shingle roofing system is an eco-friendly choice, making them the environmental choice of all roofing systems. A lifespan of 30 years or longer, is another attraction. 

Metal Roofing Systems

Metal roofing systems have proven their value because they are a viable choice because of the benefits of metal roofing systems offer like lightweight, low maintenance, UV reflective, and environmentally friendly. The installation of a metal roofing system can be tricky and should only be done by a contractor with metal roofing experience. 

What is the most commonly used residential roofing material?

But the most common of all roofing systems is asphalt shingles. The least expensive yet durable material comes ins three different types: 

• 3-tab asphalt shingles
• Dimensional shingles
• Luxury shingles

With proper installation and attic ventilation, asphalt shingle roofing materials will give you a lifespan of up to 25 years. 

What is the longest-lasting roofing material?

The material for the longest-lasting roofing systems is clay, concrete, or slate tiles. Each of these is an all-natural material and last longer than other natural material like wood shakes. However, while they are stated for long life, they are not as durable as other roofing systems. 

What type of roof will last the longest?

Slate roofing systems are referred to as the “forever roof” and a trip through Europe can prove that to be fac. Clay and slate are the most common materials on homes across Europe and have been there for 100s of years, even 1000s. Slate is the roofing material that can stand up to the elements and withstand the times.

What type of roof reflects the most heat?

Metal roofing systems are an excellent reflective roofing material, especially when coated with white paint, over 60% of the sun’s energy is reflected away from the house. Ideal where the climates are hot, this roofing material is more expensive than asphalt, but provides a longer lifespan. 

What is the most expensive roofing system?

The most expensive roofing material is slate, but you will get well over 100 years of durability and characteristic style.  This incredibly sustainable roofing material is all-natural and gives any home an upgrade. However, it is a heavy material, and an engineering report should be done before installation to assure the structure can withstand the weight. 

Is green roofing just solar panels?

No, green roofing is much more detailed than solar panels. However, having solar panels on green roofing is done, and achieves more for the environment. Green roofing is built for growing medium by mixing mineral aggregates and a small amount of organic material. Yes, it is planting a garden, park, or simply just grass on an otherwise flat roof. 

Can you install green roofing on a commercial building?

Green roofing has been practiced in Europe for decades, most of which are still in place. Here in the United States, green roofing is finally becoming more common, usually on commercial structures with flat roofing. 

Can you install green roofing on your home?

Again, Europe is way ahead of Americans with green roofing, as most homes with flat roofing are topped with green roofing.  Here in America, it is slow to gain popularity but has picked up in multi-unit residential structures.  The tenants often take the responsibility for maintenance and upkeep and every resident has the liberty to reap the rewards of green roofing like fruits and vegetables. 

How are green roofs installed?

The layer of vegetation for building green roofing is planted over a waterproofing system. There are three categories of green roofing: 

• Extensive Green Roofing: The growing medium is shallow, less than six inches, creates a modest roof load with limited diversity in plants, and has a minimum requirement for watering. This type of green roofing is usually not accessible. 
• Intensive Green Roofing: This also is a deeper medium, several feet that can support a diverse plant selection, with small trees. This is a heavier load on the structure that requires more maintenance and frequent watering. This type of green roofing is typically an accessible area.
• Semi-Intensive Green Roofing: This green roofing is a combination of the first two and engineering reports and a study of the roof will determine the type of planting based on the annual rainfall, and stormwater requirements.

The anatomy basics for any of these green roofing types will consist of the same basics that include: 

• Vegetation
• Growing Medium
• Filter Membrane
• Drainage Layer
• Waterproof Layer
• Root Repellant Layer
• A roofing membrane that can support the plantings
• Thermal Insulation
• Vapor Control layer
• And most of all, structure support for the roof

Green roofing can be installed as one large section, integrated for each plant, or with small portable planting beds that are placed together, creating a larger green roofing result. This can be done so that the layers below the planters can be inspected. 

How long does it take to install a green roof?

It depends on the size of the roof surface that is being planted with green roofing materials. A standard residential house can usually be done within one day.  A larger commercial size building can take one to two weeks. 

What are the benefits of green roofing?

There are many benefits to be had with green roofing, including the following four benefits: 

• Economically: Green roofing is more costly to install but with the increase of R-value, the economics of this endeavor will offset that higher cost. The higher insulation keeps the building cooler in summer, and warmer in winter, and that eases the HVAC workload, equals dual savings: The utilities and the HVAC system last longer. Traditional roofing typically must be replaced within 20 to 25 years. Green roofing is known to last 40 years or longer, saving money by not needing new roofing. 

• Stormwater Management: Green roofing helps control water retention and stormwater runoff, a big plus in areas of increased urbanization where green space is reduced and replaced with impervious surfaces.

• IAQ and Urban Heat Island: In a city where the surroundings are higher temperatures, referred to as the urban heat island effect, green roofing reduces that effect by lowering the temperature. Instead of more paved surfaces absorbing heat and releasing back into the surrounding atmosphere, green roofing covers the dark roofing surface and absorbs less heat while utilizing solar radiation to evaporate the heat through the plants. 

• Greenhouse Gas Emissions Reduced: With green roofing reducing the cooling loads, the greenhouse gas emissions are reduced too due to less HVAC use. 

How often does a green roof need maintenance?

The required maintenance for green roofing depends on the climate and the plantings. Below are some guidelines for an extensive amount of green roofing: 

• Watering: Green roofing systems are typically installed with drought-resistant varieties that won’t require a built-in irrigation system. During prolonged drought, extensive green roofing should be watered every 10 to 15 days with less than half an inch of water if the temperatures are 85 degrees and above. 
• Weeding: This should be done every two to four weeks, catching the weed prior to the flowering and dropping seed. 
• Fertilizing: This should be every year for the first 5 years then have the soil tested to determine the amount, frequency, and type of fertilizing going forward. 

Does a green roof still require guttering? 

 Because green roofing is typically installed on a flat roof, there should already be drains in place.  The green roofing, however, will utilize the water by having its own drainage installed. 

Is a roof leak an emergency?

An emergency roof repair is when the elements and the leak can cause further damage the home, making it inhabitable or safe. An emergency roof repair provides protection for the interior of the home until a permanent solution can be completed.

An example of an emergency roof leak would be a roof profusely leaking in one or more areas, or part of the caves in or collapses entirely. Another example is when there is roof damage caused by a storm damages the roof, leaving the interior exposed and the structure weakened. Other reasons that a roof leak is considered an emergency may be any of the following: 

• Missing Shingles: If there is a large area or several missing shingles, it may be considered needing emergency roof repair. When there are several shingles damaged or missing, it leaves the roof and the home vulnerable to more damage, including the personal belongings inside the home.  
• Rotted Roof Deck: A rotted roof deck can be considered in need of emergency roof repair. A rotted roof deck will allow moisture to build up in the attic, creating a structural hazard to the home.
• Exposed Interior: It can be a few missing shingles, or the total roof has collapsed inside the house, the answer to the question is if the roof repair can wait or is there danger of the home suffering more damage immediately? 

Can you repair a roof from the inside, and what materials are needed to repair a roof?

A temporary emergency roof repair can be done from the inside, saving the interior from more damage or harm until the actual roof itself can be addressed. You’ll need two buckets, two plastic tarps, a sheet of plywood, waterproof caulk, and roofing tar. The following steps will guide you through creating a temporary inside emergency roof repair: 

STEP 1: LOOK FOR THE LEAK

• Step One:  Find the leak, which requires getting into the attic. Roof leaks are rarely coming straight down from where the leak originates. You’ll need to follow the water dripping/running to where it is coming from. Using a flashlight will help because it will reflect on the water. If the rain has stopped, look for wet insulation and under decking, then look up above those wet areas. Once you have located the actual leaking area, circle it with chalk so you can find easier later.

If it is still raining, you’ll need to lay a tarp on the leak, and place a bucket on the tarp to catch the rain. Remove any wet insulation, this will need to be replaced now that it is compromised. 

In the living quarters of your home, where the leak is coming through, place a tarp on the floor and another bucket on the tarp. Using a nail or screwdriver, poke a hole in the bulging area of the ceiling. This will allow any built up water to drain and relieve the pressure off the ceiling. 

Now, you’ll need to wait for the rain to stop and the area to dry out before you go to the next step. This will be the time to call a roofing contractor. 

• Step Two: With the leaking area identified, take a sheet of plywood, and cut it down so that it is just a little bigger than the leaking area and waterproof caulk. Go back to the attic and spread the caulk along the edges of the plywood then press it against the roof decking over the leak. Insert nails or screws along the outer edges of the plywood to hold it in place. The spread roofing tar along the outer edges for extra sealant. 

Can you repair part of a roof?

It will depend on how much damage there is and what part of the roof is damaged. A professional roofing contractor will inspect the entire roof, including inside your home and the attic, then advise possible solutions. If they feel the entire roof is compromised, they will recommend a complete roof replacement. Then the insurance adjuster will inspect the roof in the same or similar manner the roofing contractor and advise their findings and decision. 

How much does a roof leak repair cost?

Typically the cost can range from $500 and $1,500, with the average around $800 for and asphalt shingle roof with minor to moderate leaking.

There are multitudes of videos online to walk you through the process. It is recommended to have another person helping you and always wear a safety belt when up on the roof. 

Is it better to repair or replace a roof?

There are several factors to be considered when determining if an emergency roof repair, a permanent roof repair, or if a complete new roof is needed:  

1. Age

Depending on the existing roofing material and how old the roof is a factor to consider. An asphalt shingled roof 10 years old or older that has suffered storm damage should be replaced.  

2. Leaks

A leaking roof is often an indication that a new roof is needed. If there are any of the following, this is just the start of what will become a bigger issue sooner than later: 

• Mildew and mold
• Rotting framing, joists, and roof sheathing
• Damaged ceilings and walls
• Wet or destroyed attic insulation

3. Damage 

Hiring a local roofing contractor that has a reputation of reliable, they will inspect the extent of the roof damage and help you decide the best route to take. They will consider the aesthetic damage and structural damage in this decision process:

• Aesthetic damage shown by old and worn roofing material, algae, moss, and dark streaks on the roof. 
• Structural damage shown by shingles that are cupped or curled, missing granules or bald shingles, shingles that are bent, broken, cracked, or dented. Rusted metal roofing materials.  

4. Geographical 

If your home is located in region that is susceptible to strong weather elements like hailstorms, high winds, hurricanes, or tornadoes, replacing the missing shingles may not be enough. Any existing hail damage will typically require completely new roof because it is now compromised. 

5. Cost

A big concern for any homeowner is the cost of a new roof, so if an emergency roof repair can be a permanent fix for cheaper, that is the usual preference. A roofing contractor will give you the options they see along with the cost of each. Another factor that is considered is your homeowner’s insurance. What will they pay, your deductible, and if there is a mortgage holder on the property.
