A weak roof leaves a building vulnerable to damage from rainwater and pests. If you’ve recently experienced a leak or noticed the roof is weakening, consider waterproofing your structure with a roof coating. If you’re unfamiliar with this protective layer, use this guide to learn more.

What to Know About Roof Coatings

What are they?

The coatings are a protective seal, and they’re applied to damaged or aging roofs. These sealants provide waterproofing and create a thermal barrier that reflects UV rays to keep your building cooler. Many products are corrosion-resistant and contain additives to increase the adhesive bond between the roofing materials and decking.

Acrylic coatings are affordable and widely used for short-term sealing. Polyurethane formulas are long-lasting and offer excellent insulation. Silicone coats provide thorough waterproofing but less UV protection than other products.

What types of roofs qualify?

Coatings are ideal for flat roofs that experience pooling water and poor drainage. They can also be used on metal roofs to prevent corrosion and on asphalt shingles to extend their life spans.

How do I know if my roof is ready for a coating?

Since a coating needs to be applied on a strong and cohesive surface, your roof shouldn’t have any worn shingles, cracks, damage, or leaks. Schedule an inspection to have a professional determine what needs to be fixed before the coating team arrives.

What’s the process like?

The technicians will clean the roof to help the sealant adhere to the surface. They’ll apply a primer and one or several layers of sealant depending on how well they dry. A sealant may extend the life span of your roof by 10 to 20 years once applied.
