AfterRoofers in Cerritos, CA
Most Cerritos homes were built between 1968 and 1985 on former Dairy Valley farmland, which means thousands of low-slope ranch roofs are reaching the 40 – 50 year mark at the same time. Roofers in Cerritos deal with a concentrated wave of aging concrete tile and second-generation composition shingles that neighboring cities with more staggered housing stock simply don’t see. Mercer Roofing handles Cerritos jobs with crews who know the tract-builder details that leak block after block, and we send every homeowner their technician’s name and photo before we arrive. Call (743) 200-8347 to schedule your free estimate.
Why Cerritos Homes Are Different
Cerritos sits 12 – 15 miles inland, close enough to the coast for marine-layer moisture to cycle through aging flashing, but far enough inland for serious summer UV and heat loading that accelerates shingle granule loss. That combination is hard on the low-pitched rooflines that dominate here, typically 2:12 to 4:12 pitches on single-story and split-level California ranch tracts.
The Santa Ana winds are a real factor too. They funnel through the basin corridor near the 91/605 interchange and lift or crack brittle aged tiles on older homes. We’ve found the same construction flaw across entire neighborhoods: shallow-pitch porch and garage roofs tied into the main roofline with step flashing that was never properly counter-flashed. The leaks show up in virtually identical patterns, block after block.
Original concrete tile installations are now hitting a near-universal failure point: aging mortar ridge caps that crumble and let water behind. Many of these roofs have also accumulated decades of layered patch repairs and inadequate underlayment, which means full tear-offs rather than overlays are often the only honest recommendation.

"Good roof repair. The crew was a day later than planned because of rain, which I understand, but the scheduling got moved twice. Work itself is clean and has held up."
- Dale T."Replaced the ridge cap and drip edge, and fixed a sagging gutter that nobody else mentioned. Fair price."
- Phil N."Great shingles and a clean install. Wish the cleanup had been done the same day, but they came back the next morning and finished it."
