Tom Barrett founded Barrett & Sons Construction in 1998, and his sons run the crews today. When we work on a Gilroy roof, we’re working on a house we’ll drive past for years. That changes how we install Roofing, how we flash a chimney, and how we respond when something isn’t right after a storm.
Why Barrett & Sons Construction Is Gilroy’s Preferred Roofing Company
We didn’t buy our way into Gilroy with a marketing budget. We earned jobs one driveway at a time, mostly by following behind national outfits that quoted a phone price and then showed up with a different bill. Homeowners here between 50 and 70 have told us that story more times than we can count. Our answer is simple: every scope, every allowance, every price change arrives as a written change order before work happens. The allowance that isn’t on paper is a surprise waiting for a date.
Tom Barrett publishes his name, his address, and his license number. Look it up before you sign anything. Ask anyone on your street. A live person answers the phone 24 hours a day, 7 days a week, not a voicemail box and not an out-of-state call center. When you call about a leak in the 95020, you talk to someone who knows where the 95020 is and what the clay soil does to a roofline.
We also back every roofing job with our 90-Day Done Right Promise, written on the contract. If it’s not done right, Tom comes back and makes it right, one call. And on every eligible roof, permits get pulled and inspections get signed. The permit inspector works for you, not for me, and that’s why I like him.
Our Roofing Services in Gilroy
Roof Repair
Most Gilroy roof repairs we handle fall between $400 and $1,800. The typical calls are leaks around chimneys, lifted flashing at dormers, and cracked tiles after a heat spell. On older homes near the historic downtown grid, we regularly find that clay-soil movement has shifted a chimney stack just enough to break the original flashing seal. We fix the flashing, not just the shingle, because patching over a moving chimney is a bill you’ll pay twice.
Roof Replacement & Installation
A full roof replacement in Gilroy runs $8,000 to $20,000. The spread comes down to square footage, tear-off layers, deck condition, and what’s underneath the old roof. On pre-1960s ranch homes in the 95020, the deck is often the deciding factor: undersized rafters and rotted sheathing were never designed to carry saturated tile or standing seam metal. We assess the deck as part of every free estimate and write any deck repair into the same proposal, no surprises at the end.
Metal Roofing
Metal roof installation in Gilroy runs $15,000 to $40,000. Standing seam metal is the best answer to Gilroy’s thermal gauntlet: summer highs over 100°F bake conventional underlayments to a brittle crust, while metal’s expansion properties handle that heat cycle without seam failure. We install standing seam systems from GAF and CertainTeed, with details built for our climate, not a spec sheet from a cooler state.
Tile Roofing
Tile roof repair in Gilroy runs $600 to $2,500 per repair. Barrel tile, especially on Eagle Ridge and the newer subdivisions south of town, takes a beating. Hairline cracks from thermal cycling let winter rain reach the underlayment, and once that underlayment is compromised, leaks present at pipes and valleys before you see a single broken tile from the ground. We match existing barrel tile profiles and replace underlayment with high-heat materials rated for our summers.

Trusted Brands We Service in Gilroy
We install and repair GAF and CertainTeed roofing systems, and we keep common flashing, underlayment, and tile profiles in our regional stock so a Gilroy repair doesn’t wait on a two-week distributor order. If you’re replacing an old tile roof, we can source matching barrel tile. If you’re going metal, we’ll spec a standing seam system that carries a manufacturer’s warranty you can actually look up. No mystery brands off a van.
Common Roofing Problems We See in Gilroy Homes
- Baked-crust underlayment failure. Gilroy’s 100°F summers bake adhesive-based underlayments into a brittle crust. The first winter rain finds the seams and follows them inside. We replace failed underlayment with high-heat rated products, not the same material that just failed.
- Flashing separation at chimneys and dormers. The expansive adobe clay under many 95020 homes doesn’t stay put. It expands and contracts with moisture, and that movement transfers up through the walls and pushes on vertical roof penetrations. Lifted flashing is the tell.
- Undersized rafters and rotted deck sheathing. Homes built before 1960 around the historic downtown grid weren’t framed for the weight of saturated tile or metal. If we’re fixing a roof, we check the framing while we’re in there. You don’t want to learn about a rotted rafter through a ceiling collapse.
- Termite damage hidden under old decking. Gilroy’s warm winters keep termites active year-round. We’ve opened roofs on 1960s ranches and found load-bearing rafters that looked fine from below but were gone from the top. That’s a structural repair, not a shingle patch.
Pricing for Roofing in Gilroy, CA
Here’s what roofing work in Gilroy costs. These are line-item realities from our jobs in 95020 and 95021, not national averages.

| Roof Repair | $400-$1,800 |
| Metal Roof Installation | $15,000-$40,000 |

The two biggest cost drivers on Gilroy roofs are deck condition and the state of the soil beneath the foundation. Homes with expansive clay movement need more flashing work and sometimes structural reinforcement, and we’ll tell you that before you spend a dime. We don’t bid low and change the number later. If something changes, you approve it in writing first. Estimates are free, and we also offer a free second opinion on any written estimate you’ve received. Call (877) 610-1318 and we’ll come look.

FAQs - Roofing in Gilroy
Gilroy sits in a coastal thermal gap that funnels heat inland, and summer highs routinely exceed 100°F, well above San Jose. Adhesive-based underlayments bake at those temperatures, and by winter the material has degraded enough that rain finds its way through the seams. We spec high-heat rated underlayment for Gilroy jobs because that extra heat is exactly what kills the cheaper product. We can inspect what’s under your tiles and tell you whether it’s already failing. Call (877) 610-1318 for a free inspection.
Gilroy’s adobe clay expands when wet and contracts when dry, and over years that movement shifts foundations and transfers stress up through the walls. Chimney stacks and dormers are the first roof components to show it, with flashing that lifts or separates from the roofline. That’s why we often repair flashing on Gilroy homes that have no tree damage and no storm history. If you’re seeing recurring leaks at a chimney or pipe, we can determine whether clay-soil movement is the root cause. Estimates are free.
Yes. Eligible roofing replacements in Gilroy require a permit, and the inspection gets signed before we close up. We pull permits on every eligible roof job. Some contractors tell homeowners permits are optional. We don’t, because the permit inspector works for you, not for us, and the inspection record protects you when you sell the house. If you’re comparing bids, ask each contractor whether permits are included in the price. Ours are.
Yes, in most cases. Barrel tile profiles used across Eagle Ridge and the newer subdivisions south of Gilroy are still manufactured, and we source matching tile for repair work. When an exact match isn’t available, we’ll show you the closest option in writing before we order anything. We also repair the underlayment beneath the tile, because failing underlayment is the actual source of most tile-roof leaks in Gilroy. A tile that looks broken on top is often a symptom, not the cause.
Yes, it’s common. Fifteen years is young for a roof, but pipe boots and the seams around them degrade faster in Gilroy’s heat, and clay-soil movement adds stress at penetrations. If your roof is leaking around pipes at 15 years, the underlayment near those penetrations has likely failed. We can replace pipe boots and the surrounding underlayment without redoing the whole roof, and we’ll write up exactly what we’re doing before any work starts. Call (877) 610-1318 for an exact quote.
