Commercial and residential roofing systems have the same function, protecting property from weather elements, but that’s where the similarities end. In residential roofing, the slope is very steep such that people can see it from the ground hence why materials like asphalt shingles are used. In commercial roofing, on the other hand, there is a slight slope or no slope at all hence why materials like TPO are used. What does a commercial roofing project look like?
According to the narrator in the video, a TPO (thermoplastic polyolefin) roof starts with laying a dense deck recovery board.
The recovery board used should be top-quality so that it can last for the roof’s entire lifespan.
The next step is fastening the recovery board. For this step, a top-notch fastener is required, which is pinned down using a four-inch screw or nail. The fastener should be perforated so that it can bite into the board to prevent it from moving.
The last step is the installation of the TPO material. The material should be highly reflective to help the commercial building owner save money on their AC costs. A TPO pipe boot should be installed anywhere there is a penetration, like a chimney.
