Your roof deserves the best protection and many people confuse roof sealant with using a true elastomeric coating to their flat, rubber or shingle areas. Knowing the difference can help you decide which solution is best for your home or business.
Roof Sealant
Roof sealant is a particular type of product which can be used in sealing small spaces, cracks, orthogonal joints, and seams that exist on roofs. The main aim is to provide a back up waterproofing in the most vulnerable points where leaks are more likely around vents, chimneys, skylights or flashing. Caulk is usually thick and flexible, so it can be put on with a caulking gun or brush (something that might not work well for many paints unless they are diluted accordingly). These are great if you have minor leaks or weak areas and do not want to cover the entire roof. For Roof sealant, consider www.ct1.com/product-applications/ct1-the-ultimate-roof-sealant/
Roof Coating
In contrast, a roof coating is simply that - it coats the entirety of your roofs existing space helping protect it. It is often in liquid form and so, when it dries up, you get a continuous sealer that keeps out water. There are different types of coatings (acrylic, silicone, elastomeric) which serve to reflect UV rays and ensure the roof remains cool during hot days as well preventing abrasion in general. Where sealants apply to specific areas, coatings are more for protection across the whole roof.
Which Do You Need?
If you have a single leak or crack, your best choice is to use a type of sealant. A roof coating is also an affordable way to gain more comprehensive protection and enhance energy efficiency.
What these products represent is a longer lifespan with your new roof.
