When TPO makes sense
- Wet insulation or foam across large areas
- Too many old layers
- Drainage that needs rebuilding
The system
A white membrane over insulation board, seams welded with hot air, flashed at walls, drains and openings. Added insulation helps in cold winters.
Cold-weather friendly
TPO can often be installed in cooler weather than water-based coatings, useful with the short season up here.

Common questions
How long does TPO last?
Often 20+ years.
Can foam be used instead?
If the roof is mostly dry, foam over the existing roof can be an option.
