Fast, Reliable Roof Repair Across Sunnyvale
Roof repair in Sunnyvale usually runs between $350 and $1,600 for most shingle, flashing, and leak work, with larger flat-roof or Eichler deck repairs landing in the $2,500 to $6,000 range. The homes here are not like the homes in Mountain View or Santa Clara. A sixty-year-old Eichler with no attic will hide a leak until the ceiling stains, and by then the decking is already soft. We work on those roofs every month, and we answer the phone when you call. That number is (945) 303-9821.
Tilehurst Roofing is a Kingswell family company, and our Roof Repair crews serve Sunnyvale directly. No voicemail loops. No window that shifts from noon to “sometime Thursday.” You get a written price before any work starts, and a written guarantee before the crew leaves your driveway.
Why Tilehurst Roofing Is Sunnyvale’s Preferred Roof Repair Company
Sunnyvale homeowners tend to call us after someone else let them down. We hear the same story near Heritage District and on the ranch blocks east of El Camino Real: a roofer showed up once, took a deposit, and the leak came back in March. Our crews arrive in the window we give you. Every technician is background-checked and in uniform, so you know exactly who is walking your roof line.
Greg Holloway runs the repair side of the house. He was the one who pushed to make our 365-Day Done Right Promise a written part of every contract. If a repair fails inside a year, we return and correct it at no charge. That is not a marketing line. It is in the paperwork you sign before we touch the roof.
Because Roof Repair in Sunnyvale means working on flat Eichler membranes and aging tract-home shingles in equal measure, we stock materials from GAF, Atlas, and Boral locally. That keeps turnaround fast. We quote the full manufacturer range, not whatever happens to be on the truck.
Metal Roof Repair in Sunnyvale
Metal Roof Repair in Sunnyvale typically involves resealing exposed fasteners on standing-seam runs, replacing rusted panel sections near the Moffett Park corridor, or correcting failed transitions where a metal addition meets an older composition roof. The long dry season plays a role here: five to six months of intense inland UV bakes the neoprene washers on metal roof screws until they crack, and the first atmospheric river finds every one. Most metal repairs on detached garages and side additions in Sunnyvale run $450 to $1,300. Full panel replacement on a larger primary roof pushes toward $2,800 and up.
Fastener and Seam Resealing
We pull the old screws clean, inspect the panel for rust creep around each penetration, and set new fasteners with fresh washers before applying butyl sealant along the lap seams. Skipping the rust inspection is how a $500 reseal turns into a $4,000 panel job two winters later.
Panel and Trim Replacement
When a panel is too far gone, we cut it out, match the profile from our GAF or Atlas stock, and install new trim with proper underlayment beneath. On metal roofs over old wood decking, we probe the sheathing through the opening before closing it up. If the deck is soft, you know before we button the roof back on.
Commercial Roof Repair in Sunnyvale
Commercial Roof Repair in Sunnyvale covers the low-slope and built-up membranes on offices, retail bays, and industrial buildings around Lawrence Expressway, Wolfe Road, and the light-industrial blocks south of Highway 237. These roofs are usually modified bitumen, EPDM, or old tar-and-gravel, and they fail differently than residential shingles. Ponding water after a February atmospheric river finds the seam that summer UV has been quietly degrading for months. Small commercial patches run $800 to $2,200. A larger membrane section or flashing overhaul runs $3,000 to $7,500 depending on square footage and access.
Flat Membrane Patching
We clean the surface down to solid membrane, cut back the delaminated edges, and torch or cold-apply a matched patch. On tar-and-gravel roofs, we first remove the gravel ballast and inspect the underlying felts. If the membrane is dried and cracking broadly, a patch buys you a season, not a decade, and we will tell you that plainly.
Parapet and Edge Flashing Repairs
Sunnyvale’s commercial buildings lose roof water at the parapets and scuppers first. We re-flash those transitions with new metal and sealant, and we re-tape any seams in the membrane at the same time. This is the repair that keeps the leak from reappearing one wall bay over.
Trusted Brands We Service in Sunnyvale
We stock and install materials from GAF, Atlas, and Boral, plus the full range of other major manufacturers, so the product matches the home and the climate rather than whatever fits in the truck. GAF membranes and underlayments are a natural fit for Sunnyvale’s flat Eichler roofs because they handle standing UV heat well. Atlas shingles hold up on the ranch and tract homes that dominate the area west of Mathilda Avenue. Boral tile works when a replacement needs to match an existing clay or concrete tile profile. Local stock means we are not waiting on a distributor order to start your repair.
Common Roof Repair Problems We See in Sunnyvale Homes
- Silent Eichler deck rot. On the Lakewood and Cherry Chase Eichlers, the tongue-and-groove ceiling is the roof deck. A pinhole leak wicks moisture into that plank for a full rainy season before a stain shows. By the time you see it, a $1,200 membrane repair has become a $4,000 to $6,000 deck replacement.
- UV-baked tar-and-gravel cracking. Five or six months of near-rainless inland sun dries out the bitumen in old built-up roofs until it alligators. The first atmospheric river of November drives water through those cracks directly onto the plank ceiling below.
- Failed vent boots and pipe collars. Ranch homes from the 1950s and 1960s still have original rubber boots at plumbing vents. Sunlight shrinks the rubber, the seal opens, and water follows the pipe through the sheathing. A $380 vent boot replacement prevents a $2,000 framing repair.
- Remodel-triggered code upgrades. Opening walls on a Sunnyvale ranch or Eichler for a remodel triggers code inspections, and those inspections surface outdated wiring and undersized framing tied to the roof structure. If the contract has no allowance for that, the price moves mid-job. We write the allowances in before work starts.

FAQs About Roof Repair in Sunnyvale
Because on a 1950s-to-1970s home there is no modern underlayment system to catch water. The original felt is bonded tight to aged sheathing, and water has been traveling laterally under the shingles or membrane for years. Once we peel back the surface, we commonly find soft decking, rusted drip edge, and sometimes the original wiring breaches tied to the roof structure that a permit inspector will flag. The Repair team will show you photos of everything before we quote. The point of a good contractor is not to hide that; it is to price it in writing. Call (945) 303-9821 and we will walk you through it.
The simplest answer is that if your Eichler still has its original tar-and-gravel build-up, you are very likely within a few years of full replacement, even if no stain has appeared yet. Those membranes were rated for 20 to 30 years, and most are now past 50. We probe the decking from the top during a repair visit: if our awl sinks, the tongue-and-groove is already rotting from the underside, and a patch will not hold. If the decking is still sound, a targeted membrane repair makes sense. That evaluation is free, and we will show you the probe results before any work is quoted. Reach the Repair team at (945) 303-9821.
Yes, our Commercial Roof Repair crew handles the low-slope and built-up roofs on offices and retail buildings along Wolfe Road, Lawrence Expressway, and the industrial blocks near Moffett Park. We also do metal roof repair on the standing-seam and panel systems common on side additions and detached garages throughout Sunnyvale’s residential streets. Same written price before work starts, same written guarantee after. Call (945) 303-9821 with the address and we will schedule the free estimate.
We write a contract that separates the known repair from a line-item allowance for hidden conditions. You see the exact per-unit price for deck plank replacement, framing repair, and electrical correction before we touch the roof. If we open the membrane and find rot, you approve that allowance in writing before we proceed. Nothing gets added verbally. That is the only honest way to quote a Repair in Sunnyvale, where an Eichler’s hidden deck rot can double the original estimate. Ask Greg Holloway for a contract breakdown when you call (945) 303-9821.
One square is 100 square feet of roof surface. Ask every roofer to show the actual repair area in squares and line-item the materials and labor separately. Then ask what happens to the price when decking is rotted under the membrane. Many bids look lower because the roofer assumed everything under the surface is fine. We show the square count, the probe findings, and the allowance for hidden work in writing. Comparing true totals is the only way to compare. Get that from us at (945) 303-9821, free.
