Roof coatings are renowned for their excellent protective properties. Modern flat rooftops would not survive the constant onslaught of the elements without a protective roof coating. While most flat rooftops last around 20 to 30 years, adding a roof coating can extend the life of your flat roofing system. But just how long do roof coatings last? Let’s find out.


Asphalt-based roof coatings use a solvent to make them thinner and easier to apply to a roof without heavy equipment. It can be brushed or sprayed on and works best on metal roofs, built-up roofs, and membrane roofs. Asphalt roof coatings usually have a lifespan of around 5 to 10 years.

Acrylic elastomers are highly reflective and usually installed on bituminous and non-bituminous roofing. This reflective surface aids in deflecting heat, keeping your building cooler and better insulated. Acrylic is highly durable. It has been used for decades for industrial purposes, and because of its easy application, it is more cost-effective and provides the best value. Your acrylic roof coating will likely last between 10 to 15 years.

Silicone roof coatings are extremely UV stable and reflect up to ninety percent of the sun’s harmful rays. This protects your building from harmful UV rays and becomes an insulator of heat in the winter. Because silicone coatings are not water-based, they absorb no moisture. Silicone roof coatings can withstand extreme temperatures, downpours, and oxidation. Silicone coatings are better at protecting structures from ponding water than other coatings. You can expect your silicone coating to last at least 15 to 20 years.

Urethanes are commonly used on concrete surfaces like driveways and parking garages. They can also be used on wood. They are used alone and not layered with other roofing products. Urethane coatings are perfect for high-traffic areas because they are seamless, flexible, and durable. Urethane coatings expand and contract with your roof, resist water pooling, and are more impact resistant than many other flat roof coatings. Urethanes usually have a lifespan of around 20 to 25 years.
