Article: PVC Roof Repair Edmonton, Alberta. Flat Roof. Industrial. Single Ply Membrane. DecTec.One material available to flat roof (low slope) owners is the single ply PVC roof membrane. The roof report below is specifically a DecTec type of PVC. PVC is an acronym for Poly Vinyl Chloride. PVC roofing is a single ply membrane. There are three different single ply roof membranes typically used in the market. One is PVC, the other is TPO (or thermal plastic polyolefin) and the other is EPDM (ethylene propylene diene terpolymer). PVC and TPO are welded with hot air welders (which would be different than using a torch when installing 2 ply torch-on SBS modified). EPDM seams are not welded using a hot air welder - EPDM is seamed with adhesive. PVC, TPO and EPDM are available in different colors but typically PVC and TPO are installed white and EPDM black. In all three instances (with PVC, TPO and EPDM) the roof membrane is attached to the roof assembly in one of three ways:
- Fully adhered. Fully adhering a roof membrane is the process of using a specialized adhesive to adhere the roof to the substrate or roof assembly. We typically install a residential home this way because it is lighter than ballast.
- Mechanically fastening means that the roofing contractor is installing the membrane with fasteners. Mechanically fastening a system is faster and less expensive than fully adhering it but we tend not to choose this method.
- And finally there are ballasted roof systems. A singly ply ballasted roof is typically one where the membrane is loose laid (seams are either welded or adhered) and then a smooth rock is then installed on top of the membrane to ballast it. Fully ballasted systems are less expensive and quicker to install than fully adhering the membrane, however, when possible we choose to fully adhere the system. After install service is more difficult and more costly with ballasted roofing because it takes considerable time to locate and repair leaks with ballast covering the membrane.

Today we had to roof in one roof curb with DecTec PVC. The curb was 18 inches x 40 inches. We had to wrap it with PVC and weld in 4 corners. The only issue we had today was the amount of melting snow. We were repairing and working on a down slope portion of the roof. The melting water was continually running in to our repair of the membrane laps, but we managed to get the membrane dry enough to weld.
