 How TPO is installed

TPO is Usually installed one of 3 ways

  2. Fully Adhered: With a fully adhered installation you spread a special glue called TPO adhesive to both the roof deck and the TPO. allowing drying time until tacky, once tacky you would carefully adhere the membrane to the deck avoiding trapped air which will leave bubbles.

  1. Ballast Installation: Which you ad weight or ballast to the roof usually gravel or stones, keeping the TPO secure.  

 

The TPO itself is rolled out on to the roof from sheets of 6, 10, or 12 feet wide most rolls are 100’ long, the sheets of TPO are  heat welded together to produce a monolithic membrane, covering the entirety of your roof, then wall pieces and other details assemblies  are used to completely flash and waterproof curbs, penetrations, drains and other entry points.
