Fast, Reliable Roof Replacement Across San Leandro
Roof replacement in San Leandro runs $14,000 to $32,000 for a typical single-family home, with most architectural shingle jobs landing between $18,000 and $24,000. That number changes based on decking condition, roof pitch, and access, not just square footage. Crestview Roofing has torn off and rebuilt roofs across San Leandro, from 1920s bungalows near Estudillo Avenue to 1970s tracts west of the BART tracks. Call (325) 246-5075 and we’ll scope the decking, flashing, and underlayment before we ever hand you a number.
Why Crestview Roofing Is San Leandro’s Preferred Roof Replacement Company
Dylan Pace leads Crestview Roofing, and the way we run jobs in San Leandro is simple to describe but hard to copy. We hand you a written price before any work starts, not after we open your roof and find surprises. Every crew member is background-checked and uniformed, so you know exactly who’s climbing the ladder at your home on Davis Street or over by Bayfair Center. We take before-and-after photos and send a digital invoice by text when the job closes. The 365-Day Done Right Promise covers every Roof Repair – San Leandro for a full year, with a free second visit if something fails. That’s the Relay Standard, and it applies to every roof we replace in San Leandro.
San Leandro homeowners ask us the same thing on nearly every call: will the price change once you tear off the old roof? Our answer is in writing before the first shingle comes off. We scope decking condition during the estimate, so you’re not renegotiating a plywood line item on day two. Our Roof Replacement team coordinates from the San Francisco Bay Area office and serves San Leandro with local crews who know this housing stock.
Asphalt Shingle Roof Replacement in San Leandro
Asphalt Shingle Roof Replacement in San Leandro means tearing off the existing roof to the decking, checking that decking for rot or spacing issues, then laying down underlayment, flashing, and new shingles. Most San Leandro homes we scope run $14,000 to $22,000 for a full asphalt shingle replacement, depending on whether we’re pulling one layer or three, and whether the decking underneath is sound plywood or spaced boards that need a plywood overlay. Architectural shingles from GAF or CertainTeed cost a bit more than three-tab but read better from the street and hold up longer against Bay wind and winter rain.
Architectural Shingles
This is the shingle style we recommend for most San Leandro homes, particularly the older east-side bungalows where curb appeal matters to resale value. Architectural shingles are thicker, layered, and built to take wind, and they hide minor decking imperfections better than flat three-tab.
Roof Decking Replacement
If you own a pre-1950 home near downtown San Leandro, your roof almost certainly sits on spaced 1×6 boards rather than plywood. Modern code requires solid decking under new shingles, so we lay new 1/2-inch CDX plywood over those boards before underlayment goes down. It’s a real line item, typically $1,800 to $3,500 depending on roof size, and it’s the difference between a roof that fails its inspection and one that passes.
New Roof Installation in San Leandro
New Roof Installation in San Leandro applies to additions, ADUs, and teardown rebuilds where the framing is fresh and there’s no old roof to remove. For new construction or a full re-deck, San Leandro homeowners typically spend $16,000 to $32,000, with the higher end covering steeper pitches, larger homes, and higher-grade shingles like Owens Corning Duration or IKO Nordic. Because the San Leandro building department inspects new roof installs, we pull the permit, schedule the inspection, and stay on site through sign-off. The price we write before framing starts is the price on the invoice when the inspector leaves.
Flat Roofing
A flat roof is common on San Leandro additions and carports built in the 1950s and 60s. We install modified bitumen and TPO systems with proper taper so water doesn’t pond at the seams, which is where flat roofs fail first after a wet winter off the Bay. Flat sections under 400 square feet typically run $6,000 to $11,000 as part of a larger replacement.
New Construction Roofing
For new builds in San Leandro, we coordinate with your framers and schedule roofing after the trusses are set and inspected. We quote per square, and because there’s no tear-off labor, the numbers are tighter. A 1,500-square-foot new build roof with architectural shingles usually lands between $13,000 and $19,000.
Trusted Brands We Service in San Leandro
We install and repair roofs from GAF, CertainTeed, and Owens Corning, and we stock common shingle colors and accessory parts locally in the Bay Area so a San Leandro job doesn’t stall waiting on a distributor truck from the Central Valley. If you’ve got a CertainTeed Landmark roof going on a 1970s tract house west of Hesperian Boulevard, we can match the existing ridge profile and vent color. Manufacturer-backed material warranties apply on full replacements, and our workmanship is covered under the 365-Day Done Right Promise.
Common Roof Replacement Problems We See in San Leandro Homes
- Skip-sheathing on pre-1950 bungalows. Homes near the downtown core and along East 14th often sit on spaced 1×6 deck boards, not plywood. If a roofer quotes off square count alone, you’ll get a change order on day one that could have been scoped up front.
- Rotted fascia and eave damage from Bay moisture. Morning fog off the San Francisco Bay keeps eaves damp, and older San Leandro homes with original 2x fascia often need board replacement at the eave line before drip edge goes on. That’s wood replacement, not roofing labor, and it’s a separate line item.
- Reused vent boots and pipe collars on 1960s and 70s tracts. West of the BART tracks, original neoprene boots on plumbing vents are often brittle and cracked. Reusing them under a new roof means leaks within a season. We replace them as part of the quote, not as a surprise add-on.
- Missing ice and water shield in valleys and at the eave. San Leandro’s winter rain coming off the Bay finds the seam at valleys and low-slope sections fast. We run ice and water shield through every valley and at least six feet up the eave on every replacement. It’s code in Alameda County, but not every bid includes it.
Pricing for Roof Replacement in San Leandro, CA
For a typical single-family roof replacement in San Leandro, expect $14,000 to $24,000 for asphalt shingles, $18,000 to $32,000 for architectural shingles with decking work, and $6,000 to $11,000 for a flat section added to a main roof. What moves the price: number of existing layers, decking condition once we open the roof, pitch and height, whether we’re replacing fascia or vent boots, and whether your home needs a re-nail inspection before overlay. We do not quote off square count alone, because San Leandro’s split housing stock means two 1,200-square-foot homes can need entirely different decking budgets. Call (325) 246-5075 for a written line-item quote. Estimates are free.

FAQs About Roof Replacement in San Leandro
Put the bids side by side and check three things: whether decking replacement is itemized or buried, whether new flashing and vent boots are included, and whether ice and water shield is written into the scope at valleys and the eave. A bid that’s $3,000 cheaper but omits decking overlay on a pre-1950 San Leandro bungalow will cost more once the tear-off exposes spaced boards. Dylan Pace reviews our line items with you before you sign, so you can compare apples to apples. Call (325) 246-5075 and we’ll walk through your competing bids line by line.
Yes. The City of San Leandro requires a building permit for full roof replacement, and the final nailing inspection must pass before the job closes. We pull the permit, schedule the inspection, and stay on site through sign-off. The permit fee is a line item on your written quote, not a surprise charge at the end.
Most San Leandro tear-offs and replacements take 2 to 4 working days for a standard single-story home, with a day of buffer for weather. If we find decking rot during tear-off, add a day for plywood overlay and re-nailing. We schedule a specific start date and text you a live arrival time each morning, so you’re not waiting on a four-hour window.
On a properly scoped quote, almost nothing. The items that change price on a rushed bid are decking replacement, rotted fascia, and replacement of vent boots and pipe collars. We scope those before we quote, on every San Leandro home, because we know the housing stock. If a second layer of shingles is hiding under your first one, we account for that in the tear-off line item up front. Call (325) 246-5075 for a written quote that covers the roof we can see and the decking we anticipate.
Yes, and they’re worth the $2,000 to $4,000 premium over three-tab on a San Leandro roof. Architectural shingles from GAF and CertainTeed are thicker and layered, with better wind resistance than flat three-tab, which matters when winter storms push off the Bay. They also hide minor decking inconsistencies better, which is useful on older San Leandro homes where the framing has settled. Call (325) 246-5075 to see samples and get a number for your roof.
