Chimney and flashing leaks
Leaks around the chimney stack
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.
Carson has a roofing climate most of the country would not recognise: months of relentless UV with almost no rain, then the year's water arriving in a handful of concentrated winter storms. That pattern is harder on a roof than steady weather. Sun bakes the oils out of asphalt and hardens every rubber and sealant component until it cracks, and the failures sit there unnoticed through the dry months because nothing is testing them. Then the first real atmospheric river arrives and finds all of them at once, which is why leak calls across Los Angeles County cluster into a few weeks each winter. Low-slope and flat sections are the particular weak point here — they are everywhere in the local housing stock, they pond rather than shed, and their membranes are exactly what the UV has been degrading.
Carson has a population of about 95,558, 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.
