Why Barrett & Sons Construction Is San Carlos’s Preferred Roofing Company
Tom Barrett started this company in 1998, and his sons run the crews you’ll see on your roof. That matters in San Carlos, where a lot of the homes were built between the 1940s and 1960s and have quirks you only learn by working on them for years. We know the 94070 housing stock: the Cape Cods near the flats, the ranch homes climbing the western hills, the additions that were framed in the 70s and re-roofed twice since.
San Carlos homeowners don’t want a national outfit that quotes one price on the phone and hands them a different bill at the door. They want a name they can verify. Tom publishes his name, his address, and his license number. Look it up. Ask anyone on your street. Then call us at (877) 610-1318 and talk to a live person, 24/7, not a voicemail box in another state.
Every roof we touch gets a written scope of work before the first nail moves. Price changes arrive as written change orders, approved by you before we proceed. And every completed job carries the 90-Day Done Right Promise in writing: if it’s not done right, one call brings Tom back.
Our Roofing Services in San Carlos
Roof Replacement & Installation
Most San Carlos homes are due for a full replacement when the original roof hits the 25-30 year mark, and a lot of the 1950s and 60s ranches and Capes passed that point a decade ago. Replacement in San Carlos runs $8,000-$20,000, with the final number driven by square footage, pitch, and what we find under the old shingles. On hillside homes west of Alameda de las Pulgas, we check the framing before we quote, because clay-related movement can mean structural work you don’t want to discover mid-tear-off.

Roof Leak Repair
Leaks in San Carlos have causes you won’t find in flatland Peninsula cities. Seasonal clay swelling on hillside streets shifts roof-bearing walls enough to separate flashing from chimneys, dormers, and skylights. We trace the actual source, not just the water stain on your ceiling. Roof repair in San Carlos runs $400-$1,800 for typical fixes, though structural repairs push higher.

Metal Roofing
Standing seam metal is gaining ground in San Carlos for a reason: the wind that funnels through the Coast Range gap off the Bay punishes shingle roofs on exposed western slopes. A properly fastened metal roof stands up to that. Metal roof installation in San Carlos runs $15,000-$40,000, and we install GAF and CertainTeed systems where they fit the job, with fastening details specified for San Carlos wind exposure.

Tile Roofing
The Mediterranean and Spanish-style homes in San Carlos neighborhoods off San Carlos Avenue and Brittan Avenue often carry original barrel tile. Tile roofs last, but the underlayment beneath them fails, and cracked tiles let water into the deck. We match existing tile profiles, replace underlayment properly, and address the flashing that protects your roof’s penetrations. Tile roof repair on San Carlos homes runs $600-$2,500.

Common Roofing Problems We See in San Carlos Homes
- Ridge line cracks and flashing separation on hillside streets. West of Alameda de las Pulgas, clay-rich soils swell in winter and shrink in summer. That movement shifts roof-bearing walls, cracks ridge boards, and pulls flashing away from chimneys and skylights. Flatland roofers who miss this sign off on roofs that leak within a year.
- Missing plywood sheathing on original 1950s-60s roofs. A lot of San Carlos ranch homes went up with skip sheathing or spaced boards instead of full plywood decking. When we tear off an old roof and find that, code requires sheathing upgrades before we can re-cover. That’s a written change order, not a surprise invoice, because we build the allowance into your contract up front.
- Wind-lifted shingles on western slopes. The Coast Range gap funnels afternoon wind off the Bay directly into San Carlos, especially in the higher western neighborhoods. Roofs that pass visual inspection in Redwood City fail within a year in San Carlos because the fastener schedules weren’t specified for that wind load.
- Dry rot in decking and fascia from wind-driven moisture. Winter storms push moisture inland through that same gap. Older San Carlos homes with original decking soak up that moisture, and by the time you see a stain on the ceiling, the plywood above it is swelled and rotten. We open it up, show you what’s there, and price the decking replacement in writing before we touch it.

What moves the number: roof pitch, square footage, the number of penetrations, whether the deck needs sheathing upgrades, and whether hillside conditions require structural reinforcement. We don’t hide any of that.

That’s the allowance that isn’t on paper is a surprise waiting for a date rule, and we won’t do that to you.

FAQs - Roofing in San Carlos
Because on the hillside streets west of Alameda de las Pulgas in San Carlos, clay-rich soils swell and shrink with the seasons, and that movement is exactly what cracks ridge lines and shifts roof-bearing walls. A soils report tells us whether the framing movement is seasonal swell or a deeper geotechnical problem that needs an engineered fix before we lay a new roof over it. Skipping the report can mean redoing the roof in a few years. Call (877) 610-1318 and we’ll walk you through whether your lot needs one.
The Coast Range gap at San Carlos funnels afternoon wind off the Bay, strongest from March through October, which can delay tear-off and shingle installation on exposed western slopes during high-wind days. We schedule around it, and we specify fastener patterns for San Carlos wind exposure rather than the defaults a Redwood City roof crew would use. Winter storms bring their own timing pressure, so call (877) 610-1318 early in the season for a free estimate.
Often, yes. Many San Carlos homes built in the 1950s and 60s have undersized rafters by current code, and opening the roof for a re-cover triggers the inspector’s review. When we find undersized rafters, dry-rotted sheathing, or missing plywood decking, we write the required upgrades into a change order, you approve the cost in writing, and we complete the work so the inspection passes. The permit inspector works for you, not for me, which is exactly why we like him. Call (877) 610-1318 to talk through what your roof likely contains.
Seasonal clay swelling and shrinking in San Carlos’s western hillsides moves roof-bearing walls just enough to crack ridge boards and pull flashing away from chimney, dormer, and skylight penetrations. This is structural, not cosmetic, and it’s the single most common roof failure we see in San Carlos hillside neighborhoods. On a hillside street west of Alameda de las Pulgas, we replaced the roof on a 1958 ranch where winter clay swell had shifted the trusses enough to split the ridge board and tear flashing around the chimney. Our crew opened the roof to find undersized rafters and dry-rotted sheathing, requiring load-bearing reinforcement and a change order for new plywood and Simpson ties before we could pass the inspection sign-off. We wrote the scope of work with allowances for decking replacement, so the homeowner approved the added cost in writing before we touched it. Call (877) 610-1318 if you’re seeing cracks or flashing gaps.
Yes, San Mateo County and the City of San Carlos require a permit for re-roofing, including shingle replacement over existing decking when the old layer comes off. We pull permits on every eligible job, and inspections are signed before we call the project done. It’s the same rule we follow on every job we run across the Peninsula. Call (877) 610-1318 and we’ll tell you exactly what your roof triggers before you commit to anything.
