Tpo roofing scope of work.

Also the various compounds in tpo have changed over the years which has made it challenging to determine precisely how long a single ply tpo roof is going to last. What is tpo roofing. Installation of the tpo roof membrane system and related items including flashing insulation and vapor retarder if required in accordance with the project drawings and specifications. Short for thermoplastic polyolefin tpo is a single ply roofing membrane that offers excellent performance at a cost effective price.

What goes under a commercial tpo roof depends upon whether the scope of work is a roof replacement or a roof recover. When the application is a good fit tpo systems are also a good option because they provide a layer of building insulation to the top of the building envelope while the entire system is relatively lightweight allowing it to be installed directly on top of many existing roof systems which can. So tpo is typically a good fit for warehouses areas of manufacturing facilities with few roof penetrations or rooftop equipment and multi story office buildings with limited rooftop equipment. An overall estimate puts the life of this type of roof at 10 20 years.

A commercial roof replacement project starts with removing all layers of the existing roof down to the roof deck made of wood oriented strand board osb concrete or metal. Heat welded seams provide superior strength. Tpo membranes are manufactured in sheets that are 10 12 or 20 feet wide. We then install tpo roofing underlayment comprising a vapor barrier layers of insulation a roof taper system optional and roof board.

Tpo roofing systems are made up of a single layer of synthetics and reinforcing scrim that can be used to cover flat roofs. The limited durability appears to be associated with the laminating process on the top layer of tpo products.
