Common roof problems in Los Angeles and what the repair costs

Roofs in Los Angeles wear out from sun, wind and occasional heavy rain more than from hail or snow. The downtown weather station (USC campus) records 25.6 days a year with a high at or above 90 degrees in the 1991 to 2020 climate normals, and that steady heat dries out sealants, cracks flashing and curls older shingles.

Wind is the storm to plan around. The county logged 51 thunderstorm-wind reports since 2015 in NOAA's storm records, 5 of them at 65 knots or more, and those gusts lift loose shingles and tiles. Tornadoes are rare but not absent: the county record shows 6 since 2015.

With a median build year of 1964, many roofs here are on their second or third layer or are past their working life. Call Roofers Hotline to book a roof inspection and ask for the written estimate.

Start inside, because the attic shows trouble before the shingles do. Look for dark stains on the rafters or decking, damp insulation, daylight where there should be none, and ceiling spots that grow after rain. Annual precipitation at the downtown station is 14.2 inches, so leaks often show up only a few times a year, which makes them easy to dismiss.

Outside, walk the edge of the yard with binoculars. Look for cracked, curled or missing shingles, lifted tiles, gaps around vents and chimneys, and granules collecting in the gutters. Here is one example: a homeowner sees a brown ring on the hallway ceiling the morning after a storm, finds a wet patch of insulation above it, and photographs both. A roof inspection then traces the stain to cracked flashing at a vent, and the written estimate lists that repair on its own line.

Take photos with dates and call for an inspection if you see any of these signs.

Treat active dripping, a sagging ceiling, exposed decking or a section of missing roofing as urgent. Water that reaches insulation and drywall spreads quickly, and the repair grows with every rain that follows. Federal disaster declarations that include Los Angeles County total 22 from 1969 to date, and the most recent, on April 13, 2024, was for severe winter storms, tornadoes, flooding, landslides and mudslides, so a damaged roof is worth sorting out before the next one.

Move buckets and valuables, and keep clear of any ceiling that is bulging. Roofers Hotline answers calls 24 hours a day for emergency tarping and leak repair. Smaller signs, such as a few lifted shingles or an old stain that has not changed, can wait for a scheduled inspection, but they should not wait for the next wind event.
