Roofers in Los Altos, CA
Roofing work in Los Altos is shaped by the housing stock itself: spacious mid-century estates with low-pitch or complex rooflines, original wood shake and composition shingles, and mature oaks and redwoods that drop debris year-round. That combination means more hidden rot, more flashing failures, and more careful material selection than a newer tract home would require. We’re Brennan Roofing, and we work to a written standard on every Los Altos job: the price goes on paper before any work starts, the crew is background-checked and uniformed, and every repair or installation carries a full-year written guarantee. Call (669) 238-2101 for a free estimate.
Why Los Altos Homes Are Different
The roofs we walk in Los Altos are not the roofs of a 2005 subdivision. Many were built between the 1950s and 1970s, when skip sheathing and cedar shake were standard, and when roofers didn’t anticipate sixty years of wet winters and dry summers pulling at every fastener. The mild Mediterranean climate does its own work: winter downpours followed by long dry spells cause expansion and contraction that loosens flashing and nails, while coastal fog keeps shaded roof planes damp long after the rain stops.
On streets near Foothill Expressway, steep pitches are common and cedar shakes have often accumulated moss in the shaded sections. A roofer who only looks at the surface will miss the rot underneath. We look for compromised skip sheathing, hidden decay where leaves and redwood needles have sat against the decking, and flashing that has pulled away from chimneys and skylight curbs. Los Altos remodels and additions add another layer: mixed materials, new skylights, and transitions between old and new roof sections create exactly the kind of detail where leaks start. None of this is exotic. It just requires a roofer who expects it.
Styles & brands we work with
Our Main Los Altos Services
Most Los Altos homeowners call us for one of three reasons: a roof that needs replacement, a leak that needs repair, or a property transaction that needs an inspection. Each service has its own page with full Los Altos detail.
Roofing Company in Los Altos
Full roof replacement in Los Altos usually means tearing off old wood shake or composition shingles, repairing or replacing decking that has rotted under decades of debris, and installing new underlayment, flashing, and drip edge before the finished material goes down. We work with GAF, CertainTeed, and Owens Corning product lines, and we explain the trade-offs in plain language so you can choose with confidence. The written quote you receive before work starts is the price you pay. Roofing Company in Los Altos has the full breakdown.
Roof Repair in Los Altos
Repair calls in Los Altos tend to cluster around a few recurring problems: flashing that has separated at chimneys or valleys, moss that has trapped moisture against the decking, and fastener failure from decades of expansion and contraction. We trace the actual source of the leak rather than patching the stain on the ceiling. Every repair is covered by the 365-Day Done Right Promise: if it fails within a year, we return at no charge. See Roof Repair in Los Altos for common repair scenarios and what they typically cost.
Roof Inspection in Los Altos
Los Altos home sales move fast, and a roof inspection is often the deciding line item in escrow. We inspect the field of the roof, the flashing, the decking where accessible, and the drainage details that matter on older homes. You get a written report that tells you what’s sound, what’s failing, and what it will cost to fix. No scare tactics, no inflated estimates designed to kill a deal. Roof Inspection in Los Altos explains what the inspection covers and how to read the report.

In Los Altos, two factors push prices toward the upper end of these ranges: steep pitches that require more safety equipment and slower work, and the hidden rot we often find once the old material comes off. That’s why our written quote is fixed before any work starts. If we find additional damage during tear-off, we stop and put the new number on paper before we proceed.
