Choosing The Right Roof Coating.

Choosing the right roof coating product can be a difficult task; this article will give you some basic knowledge to make an informed decision. Roof coatings have come a long way in the past twenty years from basic acrylic paint to the abundance of materials that are available today.
The most notable distinction among commercial roofs, and one that is critical when choosing a coating, is the amount of slope. Roofs with a slope less than 3:12 or 14 degrees are considered low-slope. Most commercial roofs have less than a 1:12 pitch and do not drain properly which causes a problem for most roof coatings because puddles of water will collect in low areas and remain for several days to weeks. I know this seems somewhat elementary that a roof product that is designed to keep water out would need to stand up to a little water sitting on it but many products will not last even with minimal ponding. My advice to any one looking to install a roof coating on a low-slope roof is to check the warranty first. Many products claim, in their marketing, to have excellent resistance to ponding water but the warranty states that standing water will void the warranty. This leaves the building owner holding the bag, or more appropriately the bucket which you will need to catch the leaks.
There is so much more to cover so I will have to continue the subject in the next several blog post so check back soon or better yet subscribe through email or RSS feed.
