Roof replacement in Los Altos typically runs $8,000-$20,000 for a standard ranch home, while roof repairs land between $400 and $1,800.

If you’re in Los Altos and your roof is showing its age, call Barrett & Sons Construction at (877) 610-1318 for a free, written estimate. We’ve been replacing and repairing roofs across the city since 1998, and Tom Barrett or one of his sons is on-site for most of the work.
Why Barrett & Sons Construction Is Los Altos’s Preferred Roofing Company
We’re the owner-operated alternative to outfits that quote one number on the phone and hand you a different bill at the door. Barrett & Sons was founded in 1998, and Tom Barrett still answers his own phone and stands behind every roof we put on. When you call about a Roofing job in Los Altos, you’ll get a live person, not a voicemail box. We publish our license number, our name, and our address. Look us up before you sign anything; that’s the point.
Los Altos homeowners have a particular set of concerns: protected oaks, strict tree ordinances, county stormwater rules on acreage lots, and soil that moves. We know those conditions because we’ve worked in them for decades. When a roof job in Los Altos requires an arborist’s canopy fence or a crane to bring materials in from the road, none of that surprises us. We scope it before we quote it. That’s why Tom put the 90-Day Done Right Promise on every contract: if it’s not done right, he comes back and makes it right, one call.
We carry premium roofing brands you can verify, including GAF, and every scope change comes as a written change order before work proceeds. No surprise invoices. The permit inspector works for you, not for me. That’s the way we like it.
Our Roofing Services in Los Altos
Roof Repair
Roof repair in Los Altos generally runs $400-$1,800 depending on what’s failed. In the 94022 and 94023 zip codes, we most often see lifted shingles from winter wind, failed flashing around chimneys and skylights, and gutter seams that have pulled apart. On older ranch homes off Los Altos Avenue and Miramonte Avenue, original 1960s flashing is frequently the weak point. We match materials, write the scope, and fix it without pushing you into a full replacement you don’t need yet.
Roof Replacement & Installation
For homes between 1950 and 1975, a full tear-off and replacement in Los Altos runs $8,000-$20,000. That range reflects roof size, pitch, decking condition, and how many layers we’re pulling off. Many Los Altos ranch homes still have their original wood-shake underlayment, and that changes the tear-off time and disposal cost. We’ll give you a line-item estimate before we start. If anything changes, you get a written change order first. That’s how we’ve done it since 1998.
Metal Roofing
Standing seam metal roof installation in Los Altos runs $15,000-$40,000. It’s the best answer for homes in the flatlands where Adobe clay soil moves seasonally and a heavier roof system can amplify structural movement. Metal is lighter than tile and sheds rain fast, which matters during those wet Nov-March stretches. On a ranch home off Los Altos Avenue near a protected coast live oak, our crew replaced failing wood-shake with standing seam metal while the arborist’s canopy fence was still up. We scoped the tear-off and gutter replacement around the tree’s drip line, used a crane for the long material haul from the road, and the county inspection sign-off came in ahead of schedule. That’s the kind of roofing job you only learn by doing it in Los Altos.
Tile Roofing
Tile roof repair in Los Altos runs $600-$2,500. Barrel tile is common on the Mediterranean-style homes scattered through the 94024 hills, and broken or slipped tiles after a storm are usually a quick, contained fix. But if the underlayment beneath the tile has failed, a small leak can hide for months. We inspect what’s underneath before we quote, so you’re not paying twice. Like every Barrett & Sons job, the scope is in writing before any work begins.

Trusted Brands We Service in Los Altos
We install GAF roofing systems on most Los Altos replacements because their shingle and underlayment performance holds up through the wet winters and dry summers we get here on the Santa Clara Valley floor. We also service and repair every major brand already on Los Altos homes, so you don’t have to rip off a quality roof just because one section failed. Because we work Los Altos weekly, parts turnaround is fast. We know which suppliers in the Bay Area carry what, and we stock common flashing and gutter components so a repair doesn’t wait a week for a delivery truck.
Common Roofing Problems We See in Los Altos Homes
- Protected oak complications. Los Altos’s tree-preservation ordinance is unusually strict. If a roof job is within a protected oak’s canopy zone, you may need an arborist report, canopy-protection fencing, and city sign-off before we can even stage materials. An out-of-area roofer who skips this step gets a stop-work order; we get in front of it.
- Adobe clay soil movement. The expansive clay under Los Altos’s flatlands swells and shrinks with the seasons. That differential movement can crack roofing underlayment and pull flashing away from roof-to-wall intersections on older ranch homes. When we see ceiling stains on a 1960s split-level, we look for foundation-driven movement, not just shingle failure.
- Original wood-shake underlayment. Homes built between 1950 and 1975 in Los Altos often still have original shake roofs or shake underlayment under a later overlay. That adds tear-off time, disposal weight, and occasionally decking replacement. We factor it into the quote so the price you sign is the price you pay.
- Wet-season gutter and drainage failure. Open acreage lots in Los Altos Hills and the 94024 edges of Los Altos shed a lot of runoff. Original gutters get overwhelmed, seams separate, and water backs up under the eave edge. We typically quote gutter replacement or reinforcement alongside any roof replacement on these larger lots.

What moves your number inside these ranges? Roof square footage, pitch, the number of layers coming off, decking condition, crane or lift access, and whether we’re working around protected trees or septic setbacks. On a Los Altos acreage lot, the long material haul and equipment access from the far side of the property can add line items a Sunnyvale roofer never sees. We scope all of it before we quote.

FAQs - Roofing in Los Altos
Yes, often. Los Altos’s tree-preservation ordinance requires arborist review and city sign-off when roofing work occurs within the protected zone of a heritage oak or other protected native tree. That zone is typically the tree’s drip line plus a buffer. The report, canopy-protection fencing, and permit conditions add both time and cost to the job. We handle the coordination, but don’t skip it. An unpermitted roof tear-off near a protected oak can trigger a stop-work order and fines that dwarf whatever you’d have spent doing it right. Call (877) 610-1318 and we’ll tell you whether your oak triggers a report before we even quote.
They can force equipment to enter from the far side of the property. If your septic leach field or well line sits between the road and the house, we can’t run a crane or tear-off dump trailer over it. That means longer material hauls, staging on the opposite side of the lot, and occasionally hand-carrying tear-off debris to a bin placed at the street. We identify those setbacks during the estimate and build the access plan into the price, so you’re not surprised by a change order later. An allowance that isn’t on paper is a surprise waiting for a date.
Los Altos’s building department verifies nailing patterns, underlayment and flashing details, roof-to-wall connections, and compliance with the city’s tree-protection conditions if a protected tree is nearby. They’ll also sign off on the sheathing inspection before the roofing material goes on. The permit inspector works for you, not for me. That’s why we like having them on every job. We pull the permit, schedule the inspections, and make sure every inspection passes before we call the job done.
Sometimes, but not because of the metal itself. The bigger issue is erosion control and grading on open ground. Santa Clara County stormwater rules require silt fencing, erosion controls, and sometimes temporary gravel access during the wet Nov-March months. On a big acreage lot that means prep work before the roof even starts. We plan that into the schedule so a November project doesn’t stall after the tear-off. Metal roof installation in Los Altos runs $15,000-$40,000, and part of that range reflects weather-dependent site prep.
Because the foundation moves. Los Altos sits on expansive Adobe clay that shrinks in summer and swells in winter, and original post-and-pier foundations on 1950s and 1960s split-levels ride that movement unevenly. When the house shifts, flashing at roof-to-wall intersections pulls away, underlayment stretches, and water finds a path in that has nothing to do with worn shingles. We check for that movement when we diagnose a leak in Los Altos. Fixing the roof alone without accounting for the foundation movement means the leak returns. Call (877) 610-1318 for a leak assessment; the second opinion is free on any written estimate.
