Cover-Boards: Purpose & Application

by Allen Sensel
Glass-Matt Roof Protection

When putting a low-slope roof together it’s important, as a building owner or engineer, to understand how to control moisture, combat mold, and provide fire protection. Cover-boards offer sufficient roof deck protection that meet these requirement for installing a roof. They can also serve as a purpose for re-covering your roof. These boards provide a clean, smooth surface to attach your next roof system to.

Glass-Mat Roof BoardUSG manufactures Securock, a glass-mat board that can be used on a flat roof for dimensional stability, surface protection, and overall increased lifespan of a structure. When installed correctly, Securock acts as vapor and fire barrier, keeping the roof membrane from developing mold and succeeding in fire standard ratings (rated at the maximum ’10’ with Factory Mutual [FM] Class 1 and a Class A Fire rating with Underwriters Laboratories [UL]). This is a great way to qualify for lower insurance rates as your building is less prone to fire damage.

One of the other benefits to using Securock is its ease of installation. The packaging is efficient and the board utilizes a high-quality, mat-to-core tensile bond, making each piece easy to cut and hand-break. This creates a faster labor work-flow and less of a mess to clean off of the roof surface, which helps to cut cost and keep workers focused on installing a quality roof as a whole.

As a local certified Seattle roofing contractor, we’re all about installing a quality commercial flat roof and so we recommend using USG Securock for our installations. We also specialize in single-ply residential roof systems. Give us a call at 253-445-8950 for a free estimate or drop by our website, http://www.chasenw.com.
