Fast, Reliable Roof Replacement Across Sunnyvale
Roof replacement in Sunnyvale usually runs between $14,000 and $32,000 for a typical 1,400-1,900 square foot home, depending on the roofing system, decking condition, and whether the house is an Eichler. Eichler re-roofs, which we’ll get into below, cost more, often $22,000 to $45,000, because the decking is structural and finished at the same time. Most Sunnyvale jobs take 5 to 10 working days once materials land. If you’re standing under a water stain on a tongue-and-groove ceiling right now, call Greg Holloway’s team at (945) 303-9821 and we’ll get someone out to Sunnyvale fast.
We’re Tilehurst Roofing, a Kingswell family company founded in 2000. We answer the phone live, 24 hours a day, and we put a written price in your hands before a single nail goes in. Sunnyvale’s housing stock is not like most of the Bay Area, and a roofer who treats your home like a standard ranch in Santa Clara will miss the expensive details. We don’t.
Why Tilehurst Roofing Is Sunnyvale’s Preferred Roof Replacement Company
Sunnyvale homeowners call us for a simple reason: most roofing companies do not know what to do with an Eichler. The Lakewood and Cherry Chase subdivisions alone represent one of the largest concentrations of mid-century Eichler homes in the country. Their flat and low-slope built-up roofs sit directly on tongue-and-groove planks that are the finished living-room ceiling. There is no attic. A contractor who prices these homes like a standard pitched ranch is guessing, and the homeowner pays for that guess later. We don’t guess. We probe the decking before we quote, and we have been doing it long enough that our Roof Replacement team can tell you what’s under the membrane before the first layer comes off.
Our Sunnyvale customers consistently tell us the same three things after the job: the crew arrived in the window we gave, the final invoice matched the written estimate, and the site was cleaner when we left than when we arrived. That is the Kingswell Way, and it isn’t a slogan. It’s the operating standard. Greg Holloway leads every Sunnyvale project personally, and every job carries the 365-Day Done Right Promise in writing: if it’s not done right, we make it right, for a full year. That promise is documented, not implied.
Every call to (945) 303-9821 is answered by a live person. Evenings, weekends, the middle of a storm. No voicemail tree, no callback queue.
Roof Installation in Sunnyvale
Roof installation in Sunnyvale means replacing the entire roofing system, not just the top layer. On a standard pitched roof, that is tear-off down to the decking, new underlayment, new flashing at every penetration, new drip edge, and new shingles from one of seven manufacturers: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. On a low-slope Eichler, roof installation is a different animal entirely, and we’ll explain why below.
A full roof installation in Sunnyvale typically runs $14,000 to $32,000 for a conventional pitched home. Eichler installations run $22,000 to $45,000 when decking replacement is involved. These are real numbers for Sunnyvale’s market, not national averages.
Asphalt and Architectural Shingle Systems
Most Sunnyvale ranch and tract homes built between 1955 and 1980 take architectural asphalt shingles well. They handle the summer UV, they shed rain fast during atmospheric river events, and they give you 30-plus years when installed correctly. We stock GAF, CertainTeed, and Owens Corning locally, so a Sunnyvale job doesn’t wait on a truck from Sacramento.
Flat and Low-Slope Roof Systems
Flat roofing in Sunnyvale is almost always an Eichler conversation. The original tar-and-gravel built-up roofs on Lakewood and Cherry Chase homes were good systems when they were installed, and most of them are now 15 to 25 years past their service life. We specify modified-bitumen membranes, most often GAF, because they tolerate the thermal cycling and UV load better than older BUR patches. If the decking is sound, an Eichler membrane replacement can run $18,000 to $28,000. If the decking is shot, add $6,000 to $12,000.
Roof Replacement Contractor in Sunnyvale
A roof replacement contractor in Sunnyvale has to do two things well: understand the Eichler decking problem and show up when promised. We do both. When you hire Tilehurst Roofing as your replacement contractor, you get a written scope of work before demolition starts, a fixed price that does not change at the door, and a crew of background-checked, uniformed technicians who arrive in the window we scheduled.
Replacing a roof in Sunnyvale is not a weekend project. On a standard ranch, expect 5 to 7 working days. On an Eichler with decking replacement, plan on 8 to 12. We pull permits when the job requires them, and we pass inspections before the final walkthrough. No change orders, no surprise add-ons.
Roof Decking Replacement
Decking is the wood layer under your roofing material. On a typical home, if a few sheets of plywood are rotted, you replace those sheets and move on. On a Sunnyvale Eichler, the decking is tongue-and-groove plank that is also your ceiling. When it’s rotted, there is no attic to hide the problem. The replacement is structural, precise, and must be done before any new membrane goes down. We always probe before quoting, because we would rather tell you the truth before you sign than hand you a change order after tear-off.
Trusted Brands We Service in Sunnyvale
We are not married to one manufacturer, and that matters in Sunnyvale because Eichler homes and standard ranches need different systems. We install GAF modified-bitumen on low-slope Eichler roofs, and we offer Atlas and Tamko asphalt and architectural shingles on pitched tract homes. Boral is an option we carry for homeowners who want tile or stone-coated steel in the right application. The product should fit the home, not the other way around. We keep local stock of common materials for Sunnyvale jobs, which means faster turnarounds and fewer weather delays.
Common Roof Replacement Problems We See in Sunnyvale Homes
These are the failure modes we see most often when we walk a Sunnyvale roof:
- Eichler decking rot from invisible leaks. Because the tongue-and-groove planks are the finished ceiling, water wicks in through compromised flashing and rots the wood from above for one or two rainy seasons before a stain appears. By the time you see it, the decking is often beyond saving.
- UV-baked built-up roofs. Sunnyvale gets five to six months of practically no rain and intense sun. Original tar-and-gravel membranes crack, delaminate, and lose their gravel, then the November atmospheric river finds every crack at once.
- Corroded fasteners and loosened flashing. Bay-area damp accelerates corrosion on standard galvanized fasteners. On low-slope roofs, that means the field loosens before the shingles wear out. We specify stainless or hot-dip hardware on every Sunnyvale job.
- Valley and penetration debris buildup. Low-slope Sunnyvale roofs collect leaves and debris at valleys and around pipe boots. Left uncleaned, that debris holds moisture against the roof and shortens membrane life dramatically.

FAQs About Roof Replacement in Sunnyvale
Eichler roofs cost more because the decking is structural tongue-and-groove plank that doubles as the finished ceiling. There is no attic to hide errors, no simple plywood swap. Probing, selective decking replacement, and membrane systems specified for low-slope UV exposure all add real cost. A San Jose ranch takes standard plywood decking and a standard shingle system. An Eichler takes a roofer who knows not to treat it like a San Jose ranch. Call (945) 303-9821 for an exact price on your home.
We probe it. We don’t guess, and we don’t wait until tear-off to find out. Our crew inspects the plank decking from the underside inside the house and from above after a small test cut. Soft or blackened planks tell us the truth. If we find rot, we quote the replacement before you sign. That is the Kingswell Way, and it protects you from a door-price change. Call (945) 303-9821 to schedule a decking assessment.
We specify modified-bitumen membranes, most often GAF, laid over new underlayment with stainless or hot-dip hardware at every penetration and drip edge at the perimeter. Modified bitumen handles the thermal cycling, stands up to five months of intense UV better than old tar-and-gravel, and stays watertight through atmospheric river events. Every material choice is written into your estimate before work begins. Call (945) 303-9821 for a free evaluation.
Not always. If the leak was caught early and the planks are still solid, we can sand and refinish the stain and move on. If the water wicked in for a season or two, the planks are often soft and blackened and must be replaced. We replaced two full bays of rotted tongue-and-groove planks on a Lakewood Eichler recently. The homeowner had only noticed a faint stain near a kitchen soffit. Probing found the real damage. Call (945) 303-9821 if you have a stain, no matter how faint.
Compare the decking line item first. If one bid includes probing and selective decking replacement and the other doesn’t mention decking at all, the cheaper bid is almost certainly going to hit you with a change order after tear-off. Compare membrane specs second: modified bitumen versus a cheap acrylic coating. Compare hardware third: stainless versus standard galvanized. Everything else is noise. We encourage you to read your written estimate from us line by line and ask us anything. Call (945) 303-9821 and we’ll walk you through it.
