Elastomeric Roof Coatings.
Updated: Aug 15, 2020
Elastomeric coatings is the most well known roof coating in my opinion. The elastomeric coating is commonly white or sometimes gray, but can be dyed almost any color. Elastomeric coatings have a list of great benefits. This coating can be used on shingle roofs, metal roofs, foam roofs, rolled or torch down roofs. Different manufactures will give different warranty's. They range from a five year warranty all the way up to a fifty year warranty. Elastomeric's main benefiting properties is water-proofing, heat reduction, and sealing down roofing minerals or roofing materials. It can also fill small or hairline cracks. Overall the coating limits future weathering, think of it as pausing time for the roof. In many cases elastomeric can keep pounding water from penetrating, but not always and in the earlier years of its life will loose that capability. Elastomeric is usually white, which is the color that reflects the most heat. It can also come with a sort of semi-gloss shine, which is great for reflecting ultra-violet rays (heat rays, just not light.). With all this said Elastomeric coatings are only as good as the prep work done by the contractor. The prep work is circuital just like almost any other job. You cannot apply elastomeric to a dirty roof, doing this will cause the coating to peel and separate from the roof. If you coat a leaking roof with elastomeric without repairs it will most likely continue to leak. Repairs are to be preformed prior to the coating (repaired as normal as if no coating will be applied). Once the roof is completely clean and repaired the coating can be applied. The coating will protect repairs and patches making them more water-proof and them allow them to last longer.
