Flat roofs are notoriously vulnerable to ultraviolet (UV) and moisture damage, which can shorten their lifespan significantly. Yet, roof coatings can dramatically extend the life of your roof.
How Roof Coatings Can Help
UV rays can quickly break down a roof surface, turning it brittle and increasing the risk of leaks. Some coatings reflect heat and UV rays, and cover gaps on the roof. However, keep in mind that there are different types of coatings, with each being more suited to a particular type. Listed below are factors you should consider.
The Rougher the Surface, the Better
As a general rule, roof coatings adhere better to rough and chemically active substrates. There are exceptions, however. One of them is a surface filled with gravel.
We don’t recommend applying a coating to a gravel-filled surface. Since gravel moves around too much, the coating is easily punctured. Besides, the layer of gravel already serves as a form of protection against UV rays.
Another type of roof that won’t benefit much from roof coatings is single-ply roofing, which already has a reflective surface. Concrete roofs, on the other hand, have a lot to benefit from roof coatings. That’s because they often experience high foot traffic.
Other Factors to Consider
Apart from the roof’s surface, you also need to take into account your area’s climate. Not to mention the cost of the coating. An easier way of picking a coating would be to consult a local contractor.
Just make sure to vet a contractor before hiring them. That way, you’ll lessen the risk of costly errors. Whether you need a new roof or siding installed, always do your research.
