Roofers in Winnetka, CA
Roofing in Winnetka means working on 1950s and 60s ranch homes that were built with wood shake roofs never designed for today’s Title 24 cool roof rules. The hot, dry summers bake shingles until they crack and curl, and winters bring just enough rain to find every weak flashing point. If you’re dealing with a roof that’s hit the end of its useful life, call Mercer Roofing at (341) 217-2677. We’ll send a background-checked technician whose name and photo you’ll have before they ring the bell.
Why Winnetka Homes Are Different
Winnetka’s housing stock is overwhelmingly single-story, wood-frame ranch homes from the 1950s and 60s. Most were originally built with wood shakes or basic asphalt shingles over low-slope or gently pitched roofs. That geometry matters because it means water tends to sit longer after a rain, and any small gap in the flashing becomes a leak faster than it would on a steep roof.
The bigger issue is what’s under the top layer. Many of these original shake roofs have been re-roofed two or three times over the decades, often with new layers laid directly over old shakes. When we do a full tear-off in Winnetka, we routinely find dry rot in the plywood decking that was invisible from above. Los Angeles County’s Title 24 energy code requires cool roof materials on most re-roofing projects now, which means reflective shingles and proper underlayment aren’t optional add-ons here. They’re the standard.
Thermal expansion is a year-round problem in this climate. Winnetka swings from 100-degree summer days to cool, damp winter nights. Shingles expand and contract constantly, which is why cracked asphalt and lifted flashing are the two most common calls we get from Winnetka homeowners.
Styles & brands we work with
Our Main Winnetka Services
Most Winnetka homeowners call us for one of two things: targeted repairs on an aging roof, or a complete replacement when the original 1950s shake has finally given out. Here’s what each involves locally.
Roof Repair in Winnetka
Roof repair in Winnetka usually means chasing leaks around pipe boots, valley flashing, or the low-slope transitions where ranch homes meet their attached garages. UV exposure here is relentless, so we see cracked sealant and brittle shingle tabs more than storm damage. Our team identifies the actual source of the leak, not just the water stain on the ceiling. Every repair comes with a written 365-day guarantee. If the fix doesn’t hold within a year, we return and make it right at no charge. Roof Repair in Winnetka
Roofing Company in Winnetka
As a full-service roofing company in Winnetka, we handle everything from small leak repairs to complete tear-offs and re-roofs. That includes decking replacement where hidden dry rot has compromised the wood, flashing rebuilds around chimneys and skylights, and cool roof upgrades to satisfy Title 24. Before any work begins, you’ll have a written price in hand. No surprises on the invoice. Roofing Company in Winnetka
Roof Installation in Winnetka
Roof installation in Winnetka on a 1950s ranch typically means a full tear-off down to the decking, followed by new underlayment, new flashing, and cool-rated shingles from a manufacturer like GAF or Owens Corning. Because of Title 24, reflective roofing isn’t just a preference in Winnetka, it’s a code requirement on most replacements. We specify the right material for the roof’s slope and the home’s sun exposure, then install it with a written workmanship guarantee. Roof Installation in Winnetka

What Winnetka Customers Say
"Great shingles and a clean install. Wish the cleanup had been done the same day, but they came back the next morning and finished it."
- Tasha G."Leak showed up in the hallway ceiling after a big storm. They found the failed pipe flashing in about ten minutes, replaced it, and checked the attic for wet insulation."
- Sophie R."Honest inspection. He went up, took photos, and told me I had maybe five more years instead of selling a full replacement."
- Xavier L.
