What are roof coatings
A roof coating is a protective layer of fluid applied primarily to roofs on businesses. Usually sprayed or rolled on, coatings made from materials such as silicone or acrylics are often applied to flat roofs or other commercial roofs for restoration purposes. Many business owners elect to apply roof coatings if their roofs are older and in relatively good condition, instead of replacing the roof, to extend the roof’s life.
These coatings also help improve energy efficiency, reducing heat transfer. The coatings reflect and protect from the sun’s heat and help lower energy bills. The coatings also provide some added protection from leaks. Some building owners also coat new roofs for the added benefits of their heat transfer and protection from the elements and overall wear and tear.
These coatings are especially effective on flat roofs. If you are interested in flat roof coating installation in Oklahoma City, OK, give the professionals at Validated Construction a call at 877-736-2783.
Are roof coatings any good?
Roof coatings can be a cost-effective way to increase a roof’s longevity, and reduce overall energy costs. If you are weighing your options between roof coating vs replacement, a roof coating can be a good alternative to replacement, especially if your roof is in relatively good condition.
Depending on the size of the roof, a roof coating is normally cheaper than a replacement. Coatings average about $30 per gallon. An average roof replacement for a 10,000 square-foot commercial roof costs at least $42,000, depending on the material you choose for your roof. You’ll also have to remove the whole roof when it comes to the replacement. No roofing material is removed with a roof coating application. Roof coatings can also be applied around vents and HVAC systems, and the process doesn’t disrupt business operations.
If your roof needs a large amount of repairs or has a lot of problems with leaks or other issues, replacement may be the best option. Roof coatings won’t fix structural problems that a roof replacement can address. A new roof may increase your building’s overall strength.
Does roof coating stop leaks?
If you apply a roof coating you see many immediate benefits from the coating. If you have several pinhole leaks in your roof, a roof coating will seal up small holes that cause leaks. If you have just one or two leaks, you can quickly repair them. Silicone roof coatings are particularly effective at sealing up minor leaks. Not only do roof coatings help seal up current leaks, they’ll protect your roof from future leaks because they create a watertight barrier against them.
While roof coatings protect your roof from leaks, if you want to protect your business from intruders and theft you may want to consider employing on-site security to protect your property.
When to apply roof coating
If you are planning to have a roof coating applied, you should remember that roof coatings can be affected by the weather. Ideally, the roof coating should be applied in warm weather. For best results it should be dry and 70 degrees or over. Because the application can take about two days, make sure the nights aren’t going to be really cold. Frost can also affect the coating. Each coat should be cured before the next coat is applied. The minimum outdoor temperature to apply the coating should be 50 degrees and dry.
Can roof coatings be applied over shingles
While roof coatings are normally applied to flat roofs or metal roofs, they aren’t normally applied to roofs with asphalt shingles. Although there a some coatings marketed for asphalt shingles, you may want to consult with a roof coating professional like those at Validated Construction before adding theses coatings. These coatings may not benefit an asphalt shingle roof as much as they do most flat roofing system, especially when it comes to protecting against leaks and other structural damage. Most of these coatings are acrylic based, and are often marketed to do-it-yourself homeowners. These coatings may also affect the roof’s ventilation.
How long do roof coatings last?
Most roof coatings can be expected to last about 10 years. The performance could vary depending on the thickness of the coating and the type of coating used. One advantage of roof coatings is that they can be reapplied cheaply over an older coating and remain effective for years.
Which roof coating is best?
There are several kinds of roof coatings available on the market today. Overall, the type of roof coating you choose will depend on your roofing needs. Outlined below are some common roof coatings and their advantages and disadvantages.

- Polyurethane: This coating is highly impact resistant and durable, but often cost more than acrylics. They can also have a strong odor.
- Silicone: These coatings are highly effective against ponding and leaks. They are also highly reflective and UV resistant, but the reflectivity diminishes over time.
