AfterFast, Reliable Roofing Across San Lorenzo
Roof replacement in San Lorenzo typically runs $8,000 to $20,000, and roof repair usually falls between $400 and $1,800. But the number that matters most here is the one you won’t see on an estimate: how long your roof sits half-finished because the paperwork wasn’t lined up. San Lorenzo’s 1940s Bohannon tract homes all go through the San Lorenzo Village Homes Association’s Architectural Control Committee before Alameda County will issue a roofing permit, and missing that step derails jobs every month. We file both reviews concurrently so tear-off and re-roof happen in one continuous window. Call (877) 610-1318 for a free estimate on your San Lorenzo roof.
Direct Answer: What Roofing in San Lorenzo Really Costs and How Long It Takes
A full Roofing replacement on a standard Bohannon ranch in San Lorenzo runs $8,000 to $20,000 for architectural shingles. Metal roofs, which we install regularly in San Lorenzo, range from $15,000 to $40,000 depending on profile and gauge. Tile roof repair runs $600 to $2,500. The review timeline added by the SLVHA typically adds two to four weeks before work starts, not during it. We plan around that so your roof is never sitting exposed waiting on a committee.
Why Barrett & Sons Construction Is San Lorenzo’s Preferred Roofing Company
Tom Barrett put his name on this company in 1998, and his sons run the crews that show up here in San Lorenzo. That’s not a marketing line. It means the person walking your roof is someone whose family reputation rides on whether the flashing holds through the next wet winter. We’re not a franchise sending strangers from two counties away. We know what a Bohannon roof looks like when the original sheathing has warped, and we know how the SLVHA wants materials and colors documented before we file.
San Lorenzo homeowners call us because the alternative has burned them before. National outfits quote one price on the phone and deliver another at the door. We write every scope, every allowance, and every price change as a change order before work happens. No surprise invoices. Tom publishes his name, address, and license number. Look it up before you sign anything. That’s how we’ve kept our reputation in San Lorenzo intact for the long haul.
Every eligible roofing job here includes permits pulled and inspections signed. The permit inspector works for you, not for us, and that’s exactly why we like him. We carry GAF roofing systems on most replacements because they publish their specs, their warranties are real, and the SLVHA review process goes smoother when materials are documented in writing. And every completed job is backed by the 90-Day Done Right Promise. If it’s not done right, Tom comes back and makes it right, one call.
Our Roofing Services in San Lorenzo
Roof Replacement & Installation
Most San Lorenzo homes are Bohannon-built wood-frame tract homes from 1944 to 1952, and their roofs are aging together. The original composition shingles on these ranches have been replaced at least once, often poorly. When we strip a San Lorenzo roof, we check the original plywood sheathing before a single new shingle goes down. Undersized or warped sheathing gets replaced as part of the scope, written as a change order before we touch it, so the finished roof doesn’t start lifting in year two. Replacement runs $8,000 to $20,000.
Metal Roofing
Standing seam metal roofs are becoming more common in San Lorenzo because they survive the East Bay’s wet winters and the SLVHA often approves them when the color matches the original shake profile. On a Bohannon ranch near San Lorenzo Creek, our crew replaced a failing 1950s composition roof with standing seam metal after the SLVHA approved a color match to the original shake. We filed the architectural review and county permits concurrently, scheduled tear-off only after both approvals cleared, and reset the load-bearing fascia boards where the original framing had sagged. Metal roof installation runs $15,000 to $40,000.
Tile Roof Repair
Some San Lorenzo homes still carry original or early replacement tile, and repair work here is different from other bay area cities. The SLVHA wants replacement tile to match the original profile and color, which means sourcing specific barrel tile rather than whatever is in the yard. We handle that sourcing as part of the job. Tile roof repair in San Lorenzo typically runs $600 to $2,500.
Specialty Roofing, Gutters & More
Beyond replacements and repairs, we handle gutters and accessories, emergency and storm damage, and specialty roofing systems across San Lorenzo. The same written change order rule applies to every one of these jobs. An allowance that isn’t on paper is a surprise waiting for a date, and we don’t do surprises on San Lorenzo roofs.

Trusted Brands We Service in San Lorenzo
We install GAF roofing systems on most San Lorenzo replacements because the warranty documentation is specific enough for the SLVHA review and the performance holds up in East Bay weather. For specialty work, we work with CertainTeed products where the job calls for it. We don’t stock mystery brands off a van. If you can’t look up the material spec before signing, we don’t put it on your roof. That matters in San Lorenzo, where the Architectural Control Committee reads the cut sheets.
Common Roofing Problems We See in San Lorenzo Homes
- Undersized original sheathing. Bohannon roofs from the late 1940s and early 1950s often used plywood thinner than today’s code. When new shingles go over warped or undersized sheathing, they lift within a few years. We inspect and replace sheathing during roof repair as a written line item.
- Cease-and-desist letters from the SLVHA. A roofing contractor who skips Architectural Control Committee approval leaves you with a county permit and a stopped project. The HOA can order work halted after the county already signed off. We file both before the first shingle comes off.
- Asphalt shingle rejection at review. SLVHA-governed sections of San Lorenzo sometimes reject common 30-year dimensional shingles because the thickness or color profile doesn’t match the neighborhood’s original character. We check the current allowable list before ordering materials, so you don’t pay for a downgrade or an appeal mid-project.
- Age-related flashing failures. The original metal flashing on 70-year-old Bohannon homes is often corroded through where the roof meets the chimney or side walls. Roof leaks in San Lorenzo usually start at flashing, not shingles. We replace flashing during roof repair as standard practice.
Pricing for Roofing in San Lorenzo, CA
Here’s what roofing work costs in San Lorenzo, based on what we’ve actually quoted for Bohannon ranches and similar homes here.
| Service | Price Range |
|---|---|
| Roof Replacement | $8,000 - $20,000 |

| Tile Roof Repair | $600 - $2,500 |
Roof repair in San Lorenzo runs $400 to $1,800 for most leak repairs, flashing replacement, and shingle work. Metal roofs run higher because the material cost is higher and the profile affects the SLVHA review. What changes your price most: the sheathing condition, the roof pitch, and whether the Architectural Control Committee requires a specific color or profile that limits material options. We quote for free. Call (877) 610-1318 and we’ll give you a written line-item estimate, not a phone number with a range.

FAQs - Roofing in San Lorenzo
Yes. If your San Lorenzo home falls within the SLVHA-governed sections, the Architectural Control Committee must approve exterior materials and colors before or concurrent with pulling the Alameda County building permit. Contractors who skip this step routinely leave homeowners with cease-and-desist letters that stall the project after the county permit is issued. We file the architectural review and county permit together. Call (877) 610-1318 and we’ll walk you through the paperwork for your specific property.
The SLVHA generally approves colors and materials that match the original Bohannon-era palette: muted earth tones, weathered grays, and browns for composition shingles, and standing seam metal roofs when the color matches the original shake profile. Dimensional shingles with dramatic color variations are often rejected. We check the current allowable list before ordering materials on every San Lorenzo job.
Architectural review typically adds two to four weeks to the front end of a San Lorenzo roofing project, not to the construction timeline itself. We file the SLVHA review and county permit concurrently, then schedule tear-off only after both approvals clear. That way your roof is not torn off and left exposed while a committee decides. Call (877) 610-1318 for a realistic timeline on your specific street.
Because the original plywood sheathing on 70-year-old Bohannon roofs was often undersized by today’s standards and has warped over decades of wet winters and dry summers. When we lift shingles, we regularly find rotted decking, corroded flashing, and sagging fascia boards that were never addressed in previous repairs. We write every finding as a change order before work proceeds, so you approve the scope in writing rather than discovering a surprise invoice.
Only if the home already has tile or the specific section’s design guidelines allow tile as a compatible material. Most original Bohannon roofs used composition shingles, and the SLVHA generally does not approve switching to tile on homes that never had it. If you want the tile look, we can talk through the review process and what’s realistic before you spend a dollar. Call (877) 610-1318 for a straight answer.
