Shingles are designed to shed water, not hold it — which is why flat and low-slope roofs need a different system entirely. EPDM rubber membrane roofing provides a continuous, watertight surface engineered for the porches, additions, sunrooms, and commercial roofs where standing water would defeat a shingle roof.
EPDM (ethylene propylene diene monomer) is a synthetic rubber membrane with a decades-long track record on flat and low-slope roofs. It stays flexible through temperature swings, resists UV breakdown, and installs as large continuous sheets with far fewer seams than most alternatives — and fewer seams mean fewer places for water to find a way in.
Many Triangle homes have at least one low-slope section: a porch roof, a room addition, a sunroom, or a section over a garage. These areas are the most common source of chronic leaks when they're covered with shingles that were never designed for the pitch. Replacing that section with an EPDM membrane solves the problem at its root while the rest of the roof stays shingled.
Existing EPDM roofs usually fail at seams, flashings, and penetrations before the membrane itself wears out. If your rubber roof is leaking, we'll inspect it and tell you honestly whether a seam and flashing repair will buy you years, or whether the membrane has reached the end of its life and needs replacement.
A properly installed EPDM roof typically lasts 25 to 30 years, and often longer with periodic seam and flashing maintenance.
Sometimes — it depends on the condition of the existing roof and what's under it. We'll inspect the deck and existing layers and recommend either an overlay or a tear-off honestly.
Very possibly. Low-slope porch and addition roofs covered in shingles are one of the most common chronic leak sources we see, and a membrane system is usually the permanent fix.
