Pipe boot and vent leaks
Cracked rubber collars around pipes
Water travels along rafters and decking before it shows on a ceiling, so the stain is rarely underneath the hole. Tracing the real entry point is most of the work on a leak call and the part that separates a repair that holds from one that fails at the next storm. Done properly it means time in the attic with a moisture meter, not a guess from the driveway — and where the entry point genuinely will not reveal itself, a controlled water test on the suspected area to reproduce it.
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.
Usually. Staining patterns, moisture readings and the physical condition of flashing and boots tell most of the story. Where that is not conclusive, a controlled water test on the suspected area reproduces it without waiting for weather.
Almost always because the patch went where the stain was rather than where the water entered. Water can travel several feet along a rafter before it drops. Sealing the visible end does nothing about the gap further up the slope.
