Proper Commercial Roofing Is More Important Than You Think
Like residential roofing, commercial roofing is primarily concerned with property protection. However, commercial roofing takes more materials and is more difficult to install than residential roofing. The YouTube video titled “Business Roof Installation” by Business Construction Live walks viewers through the phases and materials needed in installing a commercial roof properly.
Bitumen, gravel and tar, and asphalt shingles are just a few elements seen in the video. Additional materials include Built-Up Roofing (BUR membrane), EPDM roof membrane, Poly Vinyl Chloride (PVC) or thermoplastic roof membrane, and metal roofing.
As shown in the video, the first step in commercial roof construction is to install a vapor barrier on top of the gypsum, steel, or wood roof deck. After that, an insulating layer is applied, followed by a cover board, a waterproofing membrane, and finally shingles. Screws are used to attach the membrane sheet along its edge. The other sheets are positioned over the fasteners and welded together using a hot air welder to create a solid roof surface. The membranes are wrapped around and fastened at the roofing’s edges using aluminum or vinyl termination bars.
