When replacement is the answer
- Large areas of wet insulation or soft decking
- Two or more existing roof layers
- Widespread blisters, splits and failed seams
- A roof that has leaked repeatedly after repairs
What TPO is
TPO is a white single-ply membrane, fastened or adhered over insulation board, with seams heat-welded together. Welded seams are strong and watertight. The white surface reflects sunlight.
Insulation and slope
Replacement is a chance to add insulation and tapered board to improve drainage — important on roofs that hold snowmelt. Better insulation also reduces heat loss that drives ice dams.
The process
- Remove old roofing to the deck
- Repair or replace damaged decking
- Install insulation and tapered board
- Install and weld the TPO membrane
- Flash walls, edges, scuppers and penetrations
Coating as an alternative
If the roof is dry and sound, a coating may cost far less. See coating or new membrane.

Common questions
How long does TPO last?
Often 20 years or more with proper installation and maintenance.
Can TPO be installed in cold weather?
Yes, within the product's limits, which makes it useful at altitude.
Is TPO the same as rubber roofing?
No. EPDM is the black rubber membrane; TPO is a white thermoplastic with welded seams.
