Valley leaks
Where two roof slopes meet
EPDM is a rubber membrane used on flat roofs, bonded rather than welded, with seams made using tape or adhesive. It fails at those seams, at upstands where the material turns up a wall, and through shrinkage over time pulling the membrane away from its terminations. It is durable in the field and repairable almost indefinitely, so a leaking EPDM roof is rarely a replacement job.
Belle Terre sits on a barrier-adjacent island where three things attack a roof at once. Salt air corrodes every metal component up there — flashing, fasteners, drip edge, vent collars — so the parts meant to outlast the shingles frequently do not, and most leaks here turn out to be metal failures rather than shingle failures. Nor'easters bring sustained wind with rain driven sideways, which gets under courses that would shed any amount of vertical water. Then winter adds ice damming at the eaves, where meltwater running down a warm roof refreezes over the cold overhang and backs up beneath the shingles. Housing stock across Suffolk County runs older than the national average, with a lot of complex roof geometry, dormers and additions — and every junction is another place flashing has to work.
Belle Terre has a population of about 808, and the housing stock here sets the pattern for what fails first on a roof.
Over many years, slightly — enough to put tension on upstands and terminations, which is where older rubber roofs most often fail. It is repairable by releasing and redressing the affected edge rather than recovering the roof.
No. They are different chemistries and the adhesives and tapes are not interchangeable. Using TPO products on EPDM produces a repair that looks fine and fails within a season.
