One of the tools that roofing contractors and homeowners use in maintaining the roof is roofing sealants. Roofing sealants are cheap and can offer a temporary solution to minor leaks and holes, especially if you are using metallic roofs on your home. A sealant becomes solid after it has been applied to any given surface.

Once added, roofing sealants extend the life expectancy of the roof. They provide an extra layer that can be the first line of defense against climate and other elements that the outdoors have to offer. Sealants are especially useful for roof types that collect water and debris such as flat roofs.

Are roof sealants and coatings effective against leaks?

Yes, there are roof coatings that can be effective against leaks like silicone roof coatings. Silicone coatings will seal up the roof and stop all existing roof leaks in your home. Another benefit of silicone coating is you do not need to find every hole and leak on your roof as it can stop the leaking once you apply it all over the roof.

Sealants can last up to ten years with the help of a reliable roofing contractor.

How is a roofing sealant applied on a roof?

  4. Cover all seams and edges of flashing with patching cement using a stiff-bristle paintbrush.

Should you apply roofing sealant on your roof?

How much does roof coating cost?

For a pre-existing roof system, flat roof coatings may cost from $0.15 to $2.00 per square foot for materials and an additional $0.50 to $3.00 per square foot for labor costs per square foot. This may look cheap but be reminded that the more challenging part is maintaining the roof and applying roofing sealants once in a while.

How often should you coat your roof?
