Roof Coating

Coatings can extend the life of your commercial roof by years and prevent premature roof failure. Coatings keep a roof from leaking or water coming into your roof, saturating your commercial buildings framework, and weakening the structural integrity.

Different Types of Coating

Elastomeric

A roof coating that is formulated with acrylic is a good option due to its ability to withstand a broad range of climates. Acrylic coating is a water-based formula that matches most roof colors. Its biggest strength is that it balances cost and performance. Acrylic coatings are easy to work with, highly reflective, and resistant to UV’s.

Unfortunately, acrylic roof coating tends to lose thickness in the elements. Therefore it is recommended that acrylic coatings be used in dryer climates, fifty degrees and above temperature wise. Though the sun will also degrade the thickness of acrylic coating and the acrylic itself over time.

Silicone

Being moisture-cured is one of the defining features of a silicone coating. The use of a silicone coating can eliminate the need of a base coating entirely. Since silicone coatings have advanced curing, the coating will fare better than other coatings with almost no erosion issues. We usually recommend this coating for commercial buildings that are located in wet climates.

Silicone roof coatings do tend to hold dirt and dust. However, rain and water can clean those right off your commercial roof. This can cause the roof to lose its reflectivity quickly. It is extremely hard to adhere to silicone, so when a roof needs a re-coating, you must make sure that you use a silicone coating that has a similar silicone composition.
