Barrett & Sons Construction has been Roofing for Los Altos homeowners since Tom Barrett founded the company in 1998. We know the neighborhoods, we know the building department, and we know which questions to ask before you sign anything. When you call, a live person answers. When we quote, you get numbers you can hold us to.

Why Barrett & Sons Construction Is Los Altos’s Preferred Roofing Company

We’re owner-operated, and Tom Barrett’s name, address, and license number are published for anyone to verify. His sons run the crews. That’s not a marketing line; it’s how a 29-year-old family company works. When a Los Altos homeowner calls with a question about a roof we installed three years ago, we don’t route them to a call center in another state. Tom picks up the phone.

Every price change on a Los Altos roof arrives as a written change order before work proceeds. That’s not a policy we adopted after a lawsuit. It’s the way Tom has run jobs since the 1990s, because he learned early that an allowance that isn’t on paper is a surprise waiting for a date. You’ll know the scope, the material allowances, the permit status, and the inspection schedule before the first nail moves.

Los Altos homeowners between 50 and 70 have told us the same story for decades: a national outfit quoted one number on the phone, and the final invoice looked nothing like it. We don’t run our business that way. We pull permits and get inspections signed on every eligible job because the permit inspector works for you, not for me. That’s why I like him. Look up our license number yourself. Ask anyone on your street who’s used us.

Roof Replacement & Installation

Full roof replacement in Los Altos is the most common job we take on, and it’s almost never a simple like-for-like shingle swap. The post-WWII ranch and split-level homes that dominate the 94022, 94023, and 94024 zip codes were built with shallow pitches and original tongue-and-groove or skip sheathing. A competent replacement starts with a structural assessment of the decking. We scope redecking with plywood where the original sheathing has sagged between rafters, and we add rigid insulation above living space on older homes where attic insulation is thin or settled. If you’re planning to stay in the house for a decade or more, we’ll walk you through the long-term economics of composition versus standing seam metal.

Standing Seam Metal Roof

Standing seam metal is a smart choice for Los Altos ranch homes with low-slope roof planes. The interlocking panels handle the wet winters far better than shingles on shallow pitches, and they carry a lifespan that outlasts most homeowners’ intended tenure. We install standing seam to match the mid-century profile of older Los Altos homes, and we spec the underlayment and insulation to handle the seasonal temperature swings between Los Altos’s hot dry summers and cool damp Decembers. Metal roof installation in Los Altos typically runs $15,000 to $40,000 depending on roof square footage, pitch, and whether we’re replacing damaged decking.

Roof Leak Repair

Leaks in Los Altos homes rarely announce themselves politely. By the time you see water staining on a ceiling, the problem has usually been working for months. We trace leaks to their source rather than patching over symptoms: failed flashing at chimney penetrations and parapet intersections, cracked tile valleys, or nail pops through worn composition shingles. On Los Altos ranch homes, we pay particular attention to chimney counterflashing because seasonal movement in the Adobe clay soils under these older foundations cracks masonry and opens gaps that let water in. Roof repair in Los Altos runs $400 to $1,800 for most jobs.

Tile Roofing

Barrel tile and flat concrete tile roofs are common on the higher-end custom homes that have replaced older ranch stock across Los Altos, particularly in neighborhoods east of Foothill Expressway. We repair cracked and slipped tiles, rebuild valleys, replace degraded underlayment beneath tile, and match profiles and colors where possible. Tile roof repair in Los Altos runs $600 to $2,500 for typical localized work. When a tile roof is beyond economical repair, we’ll give you an honest assessment before you spend another dime on piecemeal fixes.

Trusted Brands We Service in Los Altos

We install GAF composition shingles and standing seam metal systems with full manufacturer warranties, plus tile profiles matched to existing Los Altos roofs. We stock common GAF accessories locally so we’re not waiting on freight for a ridge vent or a bundle of matching hip-and-ridge shingles. For Los Altos homeowners, that means shorter lead times when a repair can’t wait. Every material we quote is named in the contract: brand, product line, color, and warranty term. You can look up exactly what you’re paying for before you sign.

Common Roofing Problems We See in Los Altos Homes

• Sagging skip sheathing on 1950s and 1960s ranches. Original 1×6 boards spaced apart between rafters simply weren’t designed for 60 years of rain and heat. A shingle-over without redecking saves money up front and leaks within a few winters. We check decking condition before we quote, not after tear-off.
• Chimney and parapet cracking from Adobe clay soil movement. Los Altos sits on expansive clay that swells in wet winters and shrinks in summer. That movement travels up through masonry and opens gaps at flashing seams. We inspect flashing and counterflashing before quoting any replacement so you don’t get hit with a masonry change order mid-job.
• Heritage oak dripline conflicts. Los Altos’s tree-preservation ordinance is among the strictest in Santa Clara County. Protected native and heritage oaks require arborist reports and canopy-protection fencing before any work can begin. Out-of-area roofers who stage materials or park equipment inside a dripline trigger stop-work orders and arborist fees. We handle this paperwork before we haul a single bundle onto your lot.
• Low-pitch roof planes that trap water. Many Los Altos ranch homes have roof slopes below 4:12, which is the practical minimum for composition shingles to shed water reliably. Long-term fixes involve standing seam metal or modified underlayment systems. We’ll tell you if your roof pitch is pushing you toward a material change that actually solves the problem.
