Flat roof repair
Porches, additions and low-slope sections.
The field membrane usually outlives everything around its edges. That's where to look.
EPDM is the black rubber membrane on a huge share of low-slope roofs in this region — additions, porches, small commercial buildings. The sheet itself is durable and forgiving. What fails is the seam tape between sheets, the flashing where the membrane turns up a wall or a curb, and the boots around pipe penetrations.
Cold weather changes the repair. Seam and flashing work needs primer and adhesive rated for the temperature, and a patch bonded to a wet or frosted membrane will not hold no matter how it looks when the crew leaves.
EPDM versus TPO comes down to the deck, the drainage and what's already up there. EPDM is forgiving and long-proven; TPO is heat-welded and reflective. Neither is the right answer for every roof, and anyone who says otherwise is selling what they stock.

Depends on the deck, the drainage and what's up there now. EPDM is forgiving and proven; TPO is welded and reflects heat.
