Where EPDM fails
EPDM membrane itself is durable — it's the seams and flashings that go. Older roofs were glued and taped at the laps, and after years of heat the adhesive lets go. Shrinkage pulls membrane away from walls and curbs, and ponding water finds the weakest seam.
What we do
- Seam and flashing repair with compatible EPDM tapes and primers — not mismatched patches.
- Skylight, curb and penetration re-flashing, the most common leak points we find.
- Coating restoration when the membrane is sound but aging — see roof coatings.
- Full replacement in EPDM, or conversion to TPO or PVC when that fits the building better.
Repair or replace?
If the field membrane is still pliable and the insulation is dry, targeted repairs or a coating usually make sense. Widespread seam failure, shrinkage and wet insulation point to replacement. We'll show you which with photos and, where needed, core samples.
