When to go with TPO
- Foam or insulation is wet over large areas
- The roof already has several layers
- Drainage needs to be rebuilt
- Coatings keep peeling because of what's underneath
How TPO works
TPO is a white single-ply membrane installed over insulation board. Seams are welded with hot air into a continuous sheet. It's then flashed up parapet walls and around canales, scuppers and openings.
Parapets and canales
On pueblo-style homes, the details at the walls matter most. The membrane is carried up the inside of the parapet and terminated securely, and canales are flashed into the new roof. See canales and scuppers.
Improve slope and insulation
Tapered insulation under the TPO can fix low spots that held water for years, and added insulation helps comfort and energy use.
Foam as an alternative
If the existing roof is mostly dry, spraying new foam over it and coating may cost less. See recoat or reroof.
