EPDM Rubber Roofs: Seams, Shrinkage, and Repairs
EPDM is a rubber membrane, usually black. Seams are taped or glued, not welded.
Strengths

Weak points
Seam adhesive can age, and the membrane can shrink and pull at edges.
- Seam separation
- Shrinkage at walls and curbs
- Heat gain from black surfaces
Options
Seam repair, edge re-securing, and coatings rated for EPDM can extend life.
Common questions
