Roofers in Winnetka, CA
Winnetka roofing work splits into two very different jobs: re-roofing the original 1950s and 60s ranch homes now showing their age, and replacing the flat or low-slope roofs on garages and additions that leak around the edges every winter. Most homeowners call us first about repair, then realize the whole roof has run its course. We give you a written price before any work starts, because the number on the page is the number on the invoice. Call (650) 456-5615 for a free estimate.
Why Winnetka Homes Are Different
Drive any street between Sherman Way and Saticoy and you’ll see the pattern: a ranch-style house with a pitched composition shingle roof, and a flat-roof addition or garage attached to it. Those flat sections are where we spend most of our repair calls in Winnetka. They need torch-down or TPO systems that drain properly – if water ponds after a winter rain, the roof fails fast. We see it regularly on the original 1950s homes and on the 1980s stucco tracts alike.
On the east side near the Orange Line, hundreds of homes had their original wood shake roofs red-tagged and replaced in the early 2000s, which left a patchwork of newer composition shingles aging at different rates. Some of those roofs are hitting 20 years old now and showing granule loss. The Santa Ana winds don’t help: they lift tiles and shingles on the windward sides of homes near Corbin and Winnetka Avenue, and the UV exposure through long dry summers bakes shingles until they crack. Any roofer working Winnetka has to know both pitched shingle work and flat roof systems – that’s not a given with every contractor.
Styles & brands we work with






Our Main Winnetka Services
Most Winnetka homeowners call us about two things: a leak on the flat section of their roof, or a full replacement on an aging composition shingle house. We also install roofs on new additions and detached structures.
Roof Repair in Winnetka
Repair calls in Winnetka usually start with a water stain on the ceiling under the flat-roof portion of the house, or missing shingles after a Santa Ana event. We find the source, show you photos of the damage, and give you a written price before we touch anything. Every repair is covered by the 365-Day Done Right Promise, in writing, included with every job. If the repair fails within the year, we come back and fix it at no charge, no negotiation. Roof Repair in Winnetka covers what we fix and what it costs.

Roof Replacement in Winnetka
A full replacement on a Winnetka ranch or stucco two-story means tearing off the old shingles, replacing any rotted decking, and installing new underlayment and shingles. If the home has a flat-roof garage or addition, that section gets its own torch-down or TPO system during the same job. You get before-and-after photo documentation, a live trackable arrival time, and a digital invoice sent by text. Roof Replacement in Winnetka walks through material options and what drives the final number.

Roof Installation in Winnetka
New construction and additions in Winnetka need roofs that match the existing home’s pitch and material, which is not always a simple spec. We install composition shingles, tile, and flat systems on new builds, ADUs, and garage conversions across Winnetka. Material availability matters here; we work with GAF, CertainTeed, Owens Corning, and Boral so the roof on your new space matches the main house and lasts. Roof Installation in Winnetka explains the process from tear-off to final inspection.
