The roof of your home is your first line of defense against harmful weather elements like rain, wind, snow and extreme heat. As such, choosing the right roofing materials is important so you can be sure that your roof can withstand external pressures.
TPO or Thermoplastic Polyolefin is a type of single ply roofing material that consists of polypropylene, polyethylene, rubber and a reinforcing filler. It is a type of thermoplastic membrane which can be softened through heating and hardened through cooling. The first TPO sheets were introduced in 1989.
The seams of a TPO roof are sealed through heat welding. TPO membranes are typically white but are also available in gray and black. TPO sheet widths range from 6 feet to 12 feet wide.
3 Ways to Install TPO Roof Membrane
- Fully adhered
Fully adhered TPO roofing is glued directly to the roof surface or substrate. A fully adhered roof does not use fasteners, which means it does not allow condensation.
- Mechanical fasteners
A mechanically fastened TPO roofing uses fasteners to bolt the roof into the substructure beneath it.
Ballasting a TPO roof means laying it on the roof then welding the seams. After this, ballasts are used to keep the membrane in its place.
