Roof Coatings: What are they?

Commercial roofing methods have been around for as long as commercial buildings have been around. Gravel and tar built-up roofs were very popular in the 1840s. However, recent commercial buildings are built with a type single-ply membrane roofing system. For instance, if you were to look at new commercial construction, most likely the roofers would be putting on PVC (Poly Vinyl Chloride), EPDM (Ethylene Propylene Diene Monomer), TPO (Thermoplastic Polyolefin), TPE (Thermoplastic Polyolefin Elastomer) or PIB (Polyiso Butylene).

These are all great roofing methods for new construction, but what happens when you have roof leaks or a worn out old roof?

Commercial Roofing Methods for Reroofing

Roofing has come a long way since BUR, built-up roofing. In fact, if you have a commercial building, you are most likely to have a flat roof. This increases the choices for reroofing. Depending on the roofing contractor, you will most likely get different options on single-ply membrane roofing products. However, what if your commercial roof doesn’t need a tear off and the membrane is still in relatively good shape? Also, what if your commercial building has a metal roof on it. This is very common for many industrial and commercial buildings. Tearing off and replacing metal is very expensive.

What options does a commercial building owner have?

First, the building owner should see how many roofs are already on the building. By law, you can only have two roofing layers on a commercial building. This definitely presents a problem for the owner because an expensive tear-off is required. Or is it?

Roof Coatings: The Best Alternative

Most people haven’t heard of roof coatings. This is really a shame. First, what are roof coatings?

A roof coating is a liquid applied roofing membrane that fully adheres to a roof to create a monolithic system. In layman’s terms, roof coatings create a roof that is one unit. Unlike, single-ply membranes like TPO and EPDM, silicone coatings are seamless. They don’t come in rolls and aren’t applied with a heat gun. This creates a more watertight roof with no flaps.

Also, you don’t have to worry about whether or not your building has two roofs on it. That law doesn’t apply to roof coatings. In fact, you can just apply the coating right over the existing roof system.

Additionally, roof coatings can cost up to 50% less than a tear off and reroof. For some good roof coating brands check out GEInland Coatings, and Tropical Roof Coatings.
