Roofing work in San Lorenzo runs $180-$340 for most asphalt-shingle repairs and $12,500-$22,000 for full replacements on typical single-story tract homes, with permits pulled through Alameda County rather than a city building department. We’re Tilehurst Roofing, a Kingswell family company founded in 2000, and our crews work the San Lorenzo market from our Bay Area dispatch office. Call us at (945) 303-9821 for a free written estimate before any work starts.
San Lorenzo’s housing stock is unlike anywhere else in the East Bay. David Bohannon’s 1944 planned community produced thousands of nearly identical homes with low-pitched roofs, original board sheathing, and decades of accumulated re-roofing layers. That uniformity means we approach every job with a predictable scope, but it also means the underlying decking is often dried out and brittle after 75-plus years of California sun and marine-layer moisture.
Why San Lorenzo Homes Are Different
The Bohannon Village tract homes that define San Lorenzo were built fast and built alike: single-story, modest square footage, simple hip or gable roofs with low slopes, all framed with board sheathing rather than modern plywood. After multiple composition-shingle re-roofing cycles, many of these roofs carry heavy layering over skip sheathing that is now dried out and brittle. Tear-off and decking assessment isn’t an upsell here; it’s a standard expectation we build into every quote.
San Lorenzo’s East Bay flatlands location creates its own maintenance cycle. Marine layer fog settles onto roofs overnight and lingers into morning hours, keeping shingles damp for extended periods. That moisture accelerates algae, moss, and granule loss, especially on the aging Bohannon-era roofs that dominate the area. Proximity to San Lorenzo Creek also concentrates drainage issues on low-graded postwar lots, so gutter and downspout routing is a recurring conversation we have with homeowners.
There’s also the permit reality. San Lorenzo is unincorporated Alameda County, so roofing permits route through the Alameda County Community Development Agency, not a city building department. Contractors accustomed to incorporated San Leandro or Hayward have to adjust their workflow and inspection scheduling for every job across this community. We’ve built that process into our standard practice here.

Roof Repair in San Lorenzo
Roof repair in San Lorenzo typically addresses the predictable failure patterns of 75-plus-year-old tract housing: dried board sheathing, layered tear-offs, and moisture damage from extended marine-layer exposure. We provide a written guarantee on every repair before the crew leaves, and if a repair fails inside the guarantee period, we return at no charge under our 365-Day Done Right Promise.

Roof Replacement in San Lorenzo
Full roof replacement in San Lorenzo means working with the constraints of low-pitched geometry, original board sheathing, and often multiple existing layers that must be stripped to assess what’s underneath. We pull permits through Alameda County and coordinate inspections on a timeline built for unincorporated jurisdiction workflows. Every replacement starts with a written price before any work starts.

What San Lorenzo Customers Say
"Had a leak over the kitchen every time it rained hard. Two other roofers wanted to replace the whole roof. Tilehurst found the bad flashing, fixed it, and it's been dry through three storms since. Honest people."
- Gary Whitfield"The estimator climbed up, took photos, and showed me the actual problem areas instead of just talking. No pressure to replace anything that didn't need it. Repair's held up great."
- Tom Easley"Gutters and a section of shingles after a big wind. Answered the phone right away, came when they said, and the price on the quote is what I paid. Easy to deal with."
