We know Los Altos roofs. Not from a database. From crawling across them. The shallow-pitch ranch homes off El Monte Road, the custom builds up in the hills near Foothill Expressway, the older neighborhoods like Old Los Altos and Barron Park where coast live oaks hang over every ridgeline. Each of these areas has its own failure patterns, and a useful inspection has to account for them before the first shingle is lifted.

Our Roof Inspection process is built for exactly this: we open enough of the roof to see what is actually happening underneath, not just what the surface looks like from a ladder. For Los Altos homeowners, that distinction matters more than in most places, because what hides under an old roof here is usually bigger than a worn shingle.

Why Brennan Roofing Is Los Altos’s Preferred Roof Inspection Company

Brennan Roofing is led by Travis Oakley, and every inspection we run in Los Altos follows the same Garrison Standard: a written report, a written price for any needed work, and a one-year guarantee on anything we do. Homeowners call us because they are tired of roofers who show up late, quote one number over the phone and another at the door, or disappear after the job. That does not happen with our crews. Every technician is background-checked and arrives in uniform, and the price goes on paper before any work starts.

We have inspected enough Los Altos roofs to know where the rot hides. On a 1950s ranch in Old Los Altos, it is usually under the eaves where oak leaves have sat for decades. In Barron Park, it is the north-facing slope where moss holds moisture against the decking. Near Mountain View and Stanford, it is wind-lifted flashing around chimneys and vents. None of this is guesswork; it is pattern recognition built from doing the work street by street.

Dispatch for our Los Altos jobs is coordinated from the brand’s San Francisco Bay Area office, but the crews who show up work Los Altos regularly. That means two things: we know how to schedule around the city’s permit process, and we know how to work near protected oaks without creating liability for you.

Roof Estimate in Los Altos

A roof estimate in Los Altos gives you a written number before any work begins, and that number should already account for what the city will require and what a tear-off is likely to expose. Too many estimates here are speculative because they price only what is visible from the ground. Our estimates start with the same discipline as our inspections: we open a test section, we look at the decking and the wiring, and we write the real number down.

Inspection-before-estimate

On most Los Altos homes built between 1940 and 1970, we run the inspection and the estimate together. The reason is simple: you cannot write an honest number for a roof you have not opened. We remove enough shingles to see the decking, check for failed underlayment, and note what the rafters are actually doing. Then the estimate reflects that, in writing.

Allowances written into the contract

When we expect a surprise, we write it into the estimate as an allowance with a defined unit price. That is not a wild guess; it is a line item. If the decking under an old Los Altos wood-shake roof turns out to be rotted, you already know what it will cost to replace. No door knock, no renegotiation.

Free Roof Inspection in Los Altos

A free roof inspection in Los Altos is not a marketing gimmick; it is how we find the truth before writing any estimate. If you call us at (361) 320-9467 and ask for an inspection on a mid-century ranch or a newer custom build, we come out, get on the roof, and document everything. The report is yours to keep whether you hire us or not.

What we open

A free inspection is not a drive-by glance. We physically lift shingles in two or three test areas, usually near the eaves and around any penetrations like vents, skylights, or chimneys. That is the only way to see if the underlayment is still bonded or if moisture has been sitting against the decking.

What we photograph

Every finding gets photographed and added to a written report. We mark the exact location of each issue on the roof so you can see it yourself. For homes in Barron Park and Old Los Altos, we also document any moss, leaf debris, or oak-related wear so the record is complete.

Trusted Brands We Service in Los Altos

We install and inspect roofs built with GAF, CertainTeed, and Owens Corning materials, among others. If your existing roof is one of these lines, we can match the product and often the color with local supplier stock, which keeps a Los Altos replacement moving. If you have a specialty material, like a tile roof on a custom build near Foothill Expressway, we will inspect it against the manufacturer’s installation standards. When a warranty claim depends on proper installation details, we document them correctly the first time.

Common Roof Inspection Problems We See in Los Altos Homes

• Rot and moss on north-facing slopes. In Barron Park and Old Los Altos, coast live oaks drop debris year-round. Leaves collect on the north side, hold moisture, and feed moss that eats into the shingle surface and eventually the decking.
• Failed underlayment hiding under intact shingles. The original wood shakes on many 1950s and 1960s Los Altos ranches were overlaid with architectural shingles instead of torn off. That traps moisture between layers and rots the decking from above, which you cannot see from the ground.
• Knob-and-tube wiring in attic spaces. Homes built before the mid-1960s often still have knob-and-tube wiring running through the attic or along the roof structure. An inspection that misses it can leave you staring at a permit delay when the city requires an upgrade.
• Flashing corrosion at roof penetrations. Wind-driven rain from the Santa Cruz Mountains direction corrodes galvanized flashing faster here than inland. Chimneys, skylights, and vent pipes on the west-facing side of Los Altos homes show the most damage.
