Roof coating is not only about protecting the roof’s structural integrity (although that is the primary purpose). It also promotes energy efficiency, protects the roof from UV rays and mold growth. On top of that, the roof coating has an aesthetic component – it simply makes your roof look better.
But many homeowners aren’t sure what their options are when it relates to a roof coating. There are several go-to solutions, and we’ll examine all of them here.
The most common option for homeowners is acrylic coating. They’re available in water-based formulas, powder, and solvent form.
They range in quality and price, but they’re the overall economical choice. The acrylic coating is standard for commercial properties, and it can be pretty versatile and decorative.
They’re easy to work with but have some downsides too. Roofers typically don’t apply acrylic coating when temperatures are freezing or if they anticipate precipitation right after the application.
Another relatively inexpensive option is asphalt coating. It can be either a solvent or an emulsion, and either aluminized or black.
The asphalt coating is suitable for inclement weather and works well in freezing temperatures. Furthermore, the aluminized asphalt coating features excellent reflectivity and is UV stable.
Many homeowners prefer silicone coating for their roofs. Why? It’s because it provides outstanding weather resistance and rarely becomes brittle or stiff.
In the past decade, silicone coatings have been all the rage in the roofing industry. Primarily, this is due to the exceptional ability of this coating to withstand ponding water.
However, the silicone coating is more expensive than acrylic and asphalt, and its reflectivity reduces over time.
Initially, the application of polyurethane coating was only viable in sprayed-in-place foam roofs. Today, they have much wider use. The polyurethane coating is best-known for its impact resistance properties.
Typically, it comes in two layers. Essentially, it’s a base and topcoat that ensures maximum UV protection and durability.
It might not be the most popular choice for residential roofing, but the bitumen-based coating is popular in commercial roofing.
It’s cost-effective, easy to apply to complex surfaces, and highly resistant to impact damage. It also provides a solid waterproofing feature. However, bitumen-based coatings are not very attractive and don’t have a wide range of applications.
