How long does roof coating last?
Summary: roof coating systems last 10-20 years, but once they reach the end of their warranty, they can be recoated and a new warranty begins. The process can be repeated, making roof coating systems a renewable and sustainable roofing system. Do you have a commercial roof that needs to be restored? Perhaps your warranty ran out, but your roof is still in good condition? Did you know you can add an elastomeric roof coating over your existing roof to extend its life? But for how long? Elastomeric roof coatings can last between 10 and 20 years.
This all depends on the thickness of the coating applied to your roof. A 10-year warranty requires 20 mils of coating. A 20-year warranty requires 30 mils of coating. At West Roofing Systems, we’ve been extending the life of well-conditioned roofs through elastomeric roof coatings since 2007 (roofing in general since 1979).

What is the best coating for a roof?
Silicone – Silicone roof coatings are the preferred choice when it comes to UV protection and resistance to ponding water. They erode much slower than other coatings without becoming brittle or hard. Modern silicone formulations have a high-solids content that typically exceeds 90 percent.
This means less material is needed to achieve the required dry film thickness. Silicone coatings are created by adding solvents and a catalyst to a silicone base. Available in white, gray, or tan, silicone can be installed on a variety of roof types including metal, modified bitumen, single-ply, EPDM, built-up roofs, and spray polyurethane foam,
Depending on the substrate, most silicone roofing systems require multiple coats at 1.5 gallons per 100 square feet. Silicones attract dirt rather easily. This means the system will gradually lose reflectivity over time if not cleaned periodically. They are also extremely slippery when moisture is present.
Do roof coatings stop leaks?
What is Roof Coating? – A roof coating helps to fill in small gaps in the roof where water may seep through. It will not stop the leak, and if water gets into the roofing system it can cause a lot of damage. So why do we use coating? When a roof is put together it is similar to a giant puzzle.
How much does a 5 gallon roof coating cover?
Ensuring you achieve optimal results – Before contacting a professional roof coating company to assist you, make sure you take the time to research multiple service providers so that you can find the right match for your specific needs. Keep in mind; the roof coating process won’t impact your business’s ability to stay open and operate.
- When you weigh the pros of coating your roof instead of the cons of not doing so, it’s well worth the amount of money you’ll spend to maintain a pristine roofing structure.
- People Also Ask Q : How much does a five-gallon bucket roof coat cover? A : on average, a five-gallon bucket of roof coat will cover about 250aquare feet using two coats; alternatively it can cover an area of 500 square feet for one application.
It all depends on your roof’s overall size and any unique design elements that need to be taken into consideration. Q : How much does it cost to spray a roof? A : While the final price you pay to coat your roof will depend on factors such as it’s size and design, most professional roof coating companies charge about $14/m2 for relatively low-end projects while the price can easily rise to $28/m2 for more tedious projects.
Can you coat an old roof?
Silicone Roof Coating Installation – One of the strengths of a silicone roof coating restoration that we often tout is the ease of installation and how convenient it is to renew your roof with this system. But what does this actually mean? If your roof is old, wearing down, leaking, losing energy, getting too hot, or failing in any way that is not structural, restoration coatings can help you.
- Simply power wash the roof, apply a primer if required (which is rare), and apply the coating to the surface of the roof.
- You may have to use some caulk and polyester fabric to properly handle difficult protrusions in the roof, but those are typically minimal in time and effort.
- That’s it: power wash, primer (if needed), apply coating.
That’s the ease of installation that we are always talking about.
What season is the best time to replace a roof?
Fall – Fall is the universal go-to season for roof replacement. With spring’s mild temperatures and early summer’s weather consistency, fall is commonly referred to as the best time of year to replace your roof. Since this season is highly sought after, finding appointment times in the fall can become tedious, so it is best to plan ahead in order to beat the rush.
What temperature should it be to coat a roof?
Dry Conditions Best for Roof Coatings Application Specifying the right roof coating is only the beginning of the process. When applying a coating, managers also must pay attention to weather conditions. Weather forecasts play a significant role in deciding when to apply roof coatings to maximize the results.
Manufacturers recommend that temperatures at the time of application be at least 40 degrees — one suggested as high as 50 degrees. They also recommend managers ensure the product has been stored in a dry, warm area, at least at room temperature. Managers should schedule the application when no rain is forecast for 24-48 hours after the application has taken place, which will enable the proper time for curing.
Also, if the roof’s surface temperature is higher than the ambient temperature at the time of application, problems could arise. “Things managers need to consider are ponding water, the curing times and the weather because you have to allow curing time for the base product that’s being applied over the primer and between coats,” says Jerry Hannah of,
- Sometimes when applying coatings, people don’t think about the cold weather.
- They look at the daily high for the temperature and not what the temperature (at the time of the coating) is or the temperature of the substrate at the time they’re going to be putting it on.
- They should consider the low temperature the night before.
There’s also a maximum temperature. If it’s too hot it may flash too fast.” Beyond the immediate weather conditions, managers also must consider the time of season in which the application is scheduled. “The time of the year of the application is important when selecting a roof coating,” Ripps says.
- Water-based coatings need appropriate amounts of time to cure or dry without the product washing off.
- In the winter or fall months, the start time of water-based applications is reduced as the sun is out later and sets earlier than other times of the year.
- This can extend the project and may result in higher installation costs.” Windy conditions are primarily a concern only during the application process, when the wind can carry spray-coating particles into a parking lot or turf area below.
“You can’t put the spray coating down in any weather, but the coating, once applied, will perform just as well in heat, rain, snow, hail, whatever it may be,” Marzahl says. “Once it is applied and cured, there are no issues.” Related Topics: : Dry Conditions Best for Roof Coatings Application
How long does it take to recoat a roof?
How long will the recoat take? – With perfect weather conditions, a 20,000 square foot roof can take around 4 days to complete a recoat. A 100,000 square foot roof can take around 10-12 days to complete a recoat. NOTE: perfect weather conditions = warmer than 50 degrees F with no rain and no wind.
What is the difference between roof coating and roof sealant?
Using Coating and Sealant For Different Purposes – Both products are used to seal the roof and keep it watertight. However, the main difference is how and where you apply it. Sealant is used to create a watertight seal along the roof’s edges and around air vents, vent pipes and screw heads.
- A fiberglass roof coating is used to cover the entire roof.
- The purpose of the coating is to fill in any visible cracks and to create a smooth, watertight surface to protect against leaks.
- It will also help reflect the sunlight to keep the interior cool.
- An application of a fiberglass coating helps to maintain a good-as-new appearance.
The methods of application are different, too, see below.
How long does it take to seal a roof?
The application of a Roof Maxx treatment takes between 30 minutes at the least and a few hours at the most. The time it takes to apply the treatment will depend on the size of your roof and the state and condition of your roof and asphalt shingles. Our local technicians will be able to give you a precise, customized estimate.
Before beginning the process of applying the Roof Maxx treatment, our technicians will conduct an initial assessment to determine the condition of your roof. They will examine your roof and give you an estimate for how long the application of the Roof Maxx treatment will take. Smaller roofs that are clean and in good repair, other than brittle and inflexible shingles, can usually be finished in as little as a half hour.
The Roof Maxx treatment will take longer, up to several hours, if the technician notes any issues that require additional steps to prepare the asphalt roof for treatment. This pretreatment tune-up may include removing debris such as sticks or leaves, sealing exposed nails, and securing loose flashing.
- All of these need to be done before Roof Maxx can be applied.
- There may be some additional problems or repairs needed before Roof Maxx can be applied.
- We will examine your roof for problems and leaks, let you know if there are any problems, and make recommendations for fixing them.
- Weather, sunshine, and age can have a damaging effect on your roof, with problems ranging from debris damage to leaking.
Roof Maxx is a specialized eco-friendly spray designed to extend the life of your asphalt roof tiles by restoring their natural flexibility, leaving them less prone to breaking and leaking. If you already have these problems on your roof, you may be able to fix them and then apply Roof Maxx to extend the life of the rest of your roof.
What color roof coating is best?
The short answer is yes! White roof coatings reflect most of the ultraviolet light from the sun, this reflectivity can help with energy savings by decreasing the amount of heat that enters your home or building. When it comes to roof coatings, one of the most important decisions you’ll make is what color to choose.
Many people think that this doesn’t matter, but in reality, the color of your roof coating can significantly impact its reflectivity. In this post, we will discuss the different colors available for cool roof coating and how they reflect heat. We will also help you decide which color is right for your home! The first step in choosing the right color for your roof is to understand the different types of cool coatings that are available.
The three main categories are elastomeric, silicone, and acrylic.
- Elastomeric – An elastomeric roof coating is a water-resistant type of roof sealant that can withstand extreme heat or cold temperatures. It’s typically used on flat roofs because it has an elastic nature which allows for some movement without cracking over time.
- Silicone – A silicone roof coating is also water-resistant, but unlike its elastomeric counterpart, it doesn’t stretch. This type of coating is ideal for roofs with a lot of curves or angles, as it can form a tight seal and prevent water infiltration.
- Acrylic – An acrylic roof coating is the most common type of roof coating and is available in both reflective and non-reflective varieties. It’s also ideal for roofing materials with a lot of curves or angles.
There are three factors that determine how well your roof will reflect solar radiation: the type of coating, its color, and thickness. Tucson Rubberized Coatings has four standard roof coating colors – white, sand, light gray, and dark gray.
- White – White roof coatings are the most reflective, and they can reflect up to 90% of the ultraviolet light from the sun. This helps keep your home cooler when it’s hot outside and can save you money on energy costs.
- Sand – Sand roof coatings are slightly less reflective than white but still have a high reflectivity rating. They reflect between 70-85% of the ultraviolet light.
- Light Gray – Light gray roof coatings have a moderate reflectivity rating, reflecting between 50-70% of the ultraviolet light.
- Dark Gray – Dark gray roof coatings have the lowest reflectivity rating, reflecting between 30-50% of the ultraviolet light.
How do I prepare my roof for coating?
Step 1: Thoroughly Clean the Surface – The first, and perhaps most important step, in the elastomeric roof coating application process is to ensure that the surface you plan to apply the coating to is thoroughly cleaned and clear of any dirt, debris, gravel, sticks, or any other obstructions before you do anything else.
If you apply your roof coating onto a dirty or unclear surface, any and all debris will be coated in the and your coating may not adhere to the surface properly due to the obstructions. This will ultimately inhibit the protective qualities the coating would normally offer and may leave vulnerable areas uncovered.
The best way to get your roof ready for elastomeric coating is to remove large debris by hand or with a pushbroom or blower. Then use a pressure washer to clear away leftover dirt and grime on the surface. If you do use a pressure washer, make sure you allow your roof to dry completely before continuing.
Can roof coating be applied over shingles?
Coating of Asphalt Shingles After Installation – Asphalt Roofing Manufacturers Association (ARMA) Many types of roofing permit the application of a coating for a variety of reasons, such as increasing solar reflectivity, resisting biological growth, improving impact resistance, or increasing roof life.
However, ARMA strongly advises against the application of any type of field-applied coating over installed asphalt shingles. There are many types and formulations of roof coatings, so it is always important to consult the shingle manufacturer before proceeding with any type of coating. Many asphalt shingle manufacturers specifically do not recommend field coating of their shingles.
Additionally, state or local building codes may prohibit this practice, as the field-applied coatings may negatively impact the performance characteristics (including the fire classification, algae resistance, impact resistance, etc.) of the roof assembly.
Some of the problems reported after asphalt shingle roofs have been field coated include shrinking of the coating, which may result in unsightly curling and/or cupping of the shingles or loosening of the granule surfacing of the asphalt shingles. In addition, non-permeable roof coatings may create a vapor-retarding layer by sealing the voids around and between the shingles.
If this occurs, it may contribute to moisture accumulation within the roofing system. It has been suggested by some that the use of field-applied coatings over existing asphalt shingles will produce overriding benefits to the homeowner, such as longer roof life, energy-use reduction, or remediation of small roof leaks.
There is limited available documentation showing the extent to which the field coating of asphalt shingles provides any of these benefits, but the risks and concerns mentioned above remain very real. Further, many coatings need regular maintenance reapplications to provide a consistent appearance. In summary, the application of a coating may be detrimental to asphalt shingles.

How thick should roof coating be?
Silicone coating thickness over seams – On any roof that has seams (most likely metal and single-ply), special attention needs to occur at the seams since they have a high probability of leaking. This is what’s called seam reinforcement and it usually happens in one of two ways: #1 – Polyester Mesh with Coating Install a polyester reinforced mesh into a liquid top coating, apply over seams, then apply additional silicone coating after the topcoat has cured.

FLAT roofs, which are usually built up with layers of roofing felt and asphalt or coal tar, should be recoated every two to four years, unless they are covered by a layer of gravel or other stone chips.
About two times a year, the roofs should also be inspected for blisters, cracks and other flaws that can lead to leaks. Coating waterproofs and protects the original roofing. It is available in five-gallon containers as a black or metallic liquid. The material is thicker than paint, but not as thick as tar.
- It is applied with a long-handled brush resembling a small push broom.
- Both types of coating contain asphalt, which seals the roof against moisture.
- Metallic coating also contains aluminum, which reflects sunlight, protecting the asphalt from ultraviolet radiation and deterioration.
- In addition, aluminum reflects heat that can weaken roofing materials and increase cooling costs.
High-quality aluminized roof coating is a better product than coating of equal quality without aluminum. But poor-quality aluminized coating is not as good as high-quality coating containing just asphalt. Following are factors to look out for in obtaining high-quality coating: *Because the amount of aluminum in aluminized coating is the most significant factor in its manufacturing cost, avoid aluminized coatings priced significantly below others.
- Extremely inexpensive coating is likely to contain little aluminum.
- If possible, learn how much aluminum is in the aluminized product you are choosing and what percentage of the metal is new, rather than recycled.
- Distributors may not have this information, but more aluminum means that the roof will receive a thicker coating, which will last longer, and pure aluminum outperforms scrap.
*When selecting pure asphalt coating, the same caution applies regarding relative price. In addition, avoid asphalt coating that is much heavier than others. A five-gallon container of asphalt coating weighing more than 50 pounds probably contains excessive fillers that are of no value to the product.
Fillers are not the same thing as fibers. Roof coating with fibers is more durable than coating without fibers, and coating with asbestos fibers is better than coating with fibers of other materials, like cellulose and polypropylene. Asbestos used in roof coating is encapsulated, meaning that the fibers are bound within the mixture and cannot be inhaled.
It is not listed as hazardous by the Environmental Protection Agency and similar agencies. To coat, wait for a dry period of warm weather. In hot weather, when roofing is soft, walking on it can cause damage. Make repairs, if necessary, and sweep the roof free of debris.
Stir the coating thoroughly. Begin spreading it with the brush at the point farthest from the ladder so that you can coat the entire roof and still climb down. Spread the coating about an eighth of an inch thick, or as specified by the manufacturer. Brush aluminized coating in one direction only and use a minimum of strokes for best results.
Dispose of the brush when finished. Unused coating can be stored up to three years if closed tightly and kept from freezing. Roof coating will not stop leaks or repair damaged roofing. Severe problems should be handled by a licensed roofer, but you can repair minor problems like isolated blisters, cracks and torn roofing without much trouble.
- To fix a blister, sweep the area and make an X-shaped slit in the roofing one layer at a time.
- Use a sharp utility knife.
- If the blister is dry inside, proceed with the repair.
- If the blister contains moisture, stand on it to squeeze out as much water as you can, prop the flaps open and let the area dry.
Repair the blister, but also locate and repair the source of the moisture, which is often cracked or torn roofing or parapet flashing. To repair the blister, spread roofing cement, a plastic or asphalt compound that is thicker than roof coating, beneath the flaps and press them flat.
- Next, spread more cement over the repair and press a piece of roof-patching material made of asphalt-saturated cotton fabric into it, embedding it completely.
- The fabric should extend about two inches beyond the damage on all sides.
- Finish by troweling a layer of cement at least one-eighth inch thick over the fabric and several inches beyond it.
Smooth the cement so that there are no ridges to collect water. To mend cracks, spread roofing cement over them, embed fabric in the cement, and cover with more cement. If roofing is torn, cut out a square or rectangle of roofing around the spot using a straightedge and a utility knife.
- Cut only as deep as the damaged layer.
- Pry out the cut section and use it as a guide to make a patch onto 15-pound or heavier roofing felt thick enough to fill the opening.
- Cement the patch into the opening.
- Then proceed as for covering a blister.
- To patch parapet flashing, pry up the metal cap protecting the ridge.
Apply roofing cement to the damaged area and cover it with a layer of new flashing material that extends three inches beyond the damage on all sides. Place the upper edge of the new flashing so that it will be covered by the metal cap when it is reinstalled.
How often should you recoat your roof in Arizona?
5) Recoat the roof every 5 to 10 years – We’re assuming your flat rooms has protective foam sealant since about 90% of Arizona’s flat roofs are protected by spray polyurethane foam. To help your flat roof last for 25+ years, it’s important to recoat your foam roof every 5 to 10 years since the sun’s ultraviolet rays eventually wear down the protective covering.
