Our Guarantee & Warranty - Brennan Roofing Co San Jose

The Brennan Roofing Co San Jose Guarantee

Every roof we touch in San Jose gets the same promise, and we don’t leave it as a handshake. Before any work starts, you get a written price. After the work is done, you get the 365-Day Done Right Promise in writing: if a repair or installation we completed fails within one full year, we come back and fix it at no charge. That’s the whole point of the name on the truck. Travis Oakley, owner of Brennan Roofing Co San Jose, signs off on that standard, and it applies to every job from a small leak repair in Willow Glen to a full replacement in Almaden Valley.

Call (669) 238-2101

We’re an independently owned local roofing company, not a faceless branch office. But we chose to operate under a named standard called The Garrison Code, the same one the Garrison Partners family has used since 2000. That means every visit starts the same way: a live person answers, a background-checked technician in uniform shows up, and the number on your written quote is the number you pay. If it’s not done right, we make it right. In writing, for one full year, at no charge.

What’s Covered

• Workmanship on every repair and installation. The 365-Day Done Right Promise covers the labor and execution of the work we performed, not just the materials on the invoice.
• Written pricing before any work starts. The price goes on paper first and it does not move at the door, no exceptions.
• Free return visit within the guarantee period. If a repair or installation we completed fails within one year, we come back at no charge for a second visit and correct it.
• Decking, underlayment, flashing, and drip edge workmanship. Every component layer we touch is part of the written guarantee, whether it’s a patch repair in Berryessa or a full replacement off Blossom Hill Road.
• Manufacturer-backed materials. We install roofing materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the products on your roof come with their own factory coverage separate from our workmanship promise.
• Cleanup and site care. We show up in uniform, protect your landscaping during the job, and clean up nails and debris when we leave. If the crew missed something, tell us and we’ll come back for it.
• Scheduled arrival and clear communication. When you book, we give you a window and we honor it. If something changes, a live person calls you, not an automated text.

Our Satisfaction Promise

If something about the job doesn’t sit right with you, call (669) 238-2101 and ask for Travis. A live person answers, not a queue. Tell us what’s wrong and we’ll make a plan to fix it. The standard in The Garrison Code is plain enough: every repair and installation is guaranteed in writing for a full year, and if it fails within that period you get a free second visit at no charge. No invoice games, no arguing about whose fault it is. We put it on paper before we start, and that paper is what we answer to afterward.

That also applies to the quote itself. The home you own in San Jose deserves a number that doesn’t shift once the crew pulls up. If you approved a written estimate and we find something under the decking we couldn’t see from the roof surface, we stop, show you the issue, and write a new number before touching it. You always know what you’re paying before the work moves forward. That’s not a courtesy. That’s how an honest roofing company operates in this city.

Licensed & Insured Backing

A written guarantee means something only if the company behind it is still standing when you need it. Brennan Roofing Co San Jose is licensed and insured to perform roofing work in California, and every technician we dispatch is background-checked and arrives in uniform. That matters when a stranger is walking across the top of your house in the Evergreen foothills or working around a steep pitch near Communications Hill. Insurance protects your property if something goes wrong on site. Licensing means we answer to the state for how the work is done. The 365-Day Done Right Promise is the guarantee you can hold in your hand, and the license and insurance are the backing that makes it enforceable.

We’re also part of the Garrison Partners family, founded in 2000. Locations are independently owned and operated, which means the person responsible for your roof actually lives and works here in San Jose, but we agree to the same written standard the whole group follows. That’s The Garrison Standard: named, defined, and written down. Not a slogan on a bumper sticker. A code we follow on every job, from a tile repair in Japantown to a full reroof near Los Gatos Creek.

How the Guarantee Works

Here’s the sequence, because we prefer you know exactly what to expect before you ever pick up the phone.

First, you call (669) 238-2101. A live person answers, day or night. You describe what you’re seeing: a water stain on the ceiling, granules in the gutter, a missing shingle after the last windstorm off the Santa Cruz Mountains. We schedule a visit and a technician shows up in uniform with a photo ID you can verify.

Second, the technician inspects your roof and walks you through what they found in plain English. Flashing is the metal that directs water away from chimneys, vents, and valleys. Decking is the plywood layer under the shingles that holds the roof structure together. Underlayment is the waterproof barrier between the decking and the shingles. Drip edge is the metal trim along the roof perimeter that keeps water from curling back under the shingles. If any of these layers need work, you’ll hear exactly which one and why.

Third, you get a written quote. Not a verbal ballpark, not a number scribbled on a business card. A line-item document with the scope of work and the final number printed on it. That price holds.

Fourth, the work is done to The Garrison Standard. We install materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, or Boral based on what fits your roof and your budget, and we explain those options plainly so you decide with confidence instead of guesswork.

Fifth, you get the 365-Day Done Right Promise in writing. One full year of coverage on the workmanship we performed. If something fails, call us. We come back free. It’s that simple, and it’s that specific.

Common Questions About Our Guarantee

How much does roof repair cost in San Jose?

Small repairs in San Jose typically run between $350 and $850 depending on what failed. A flashing replacement around a chimney or vent, a section of shingles torn loose by wind, a clogged valley that backed water under the underlayment: those are all in that range. Larger repairs that involve replacing decking sections or rebuilding a roof edge run higher, from $1,200 to $3,500. You won’t have to guess, though. The quote goes on paper before any work starts, and it does not change at the door. Call (669) 238-2101 and we’ll give you an exact number for your roof.

Will the price change once work starts?

No, not unless we uncover something hidden and we show it to you first. If the decking under your shingles is rotten and it wasn’t visible from the roof surface, we stop, take a photo, show you the affected area, and write a new line-item number before we touch it. You approve the change in writing or the original scope stays. The point of the Brennan Roofing Co San Jose guarantee is that you never pay more than the number you approved, and you never get surprised by a bill.

Do you pull permits for roof work in San Jose?

San Jose requires permits for most full roof replacements and for structural repairs. When a permit is needed, we pull it and the work passes inspection before we call the job done. That’s part of operating under The Garrison Code: the roof isn’t finished when the last shingle goes down, it’s finished when the city inspector signs off. If your repair is small enough that a permit isn’t required, we’ll tell you that plainly too.

How long does a roof repair or replacement take?

Most repairs finish in a single day. A standard full replacement in San Jose takes two to five days depending on roof size, pitch, and whether the decking needs sections replaced. Tile roofs on hillside homes in areas like the East Foothills often take longer because of the material weight and the pace required to do it right. We’ll give you a written timeline as part of the quote, and the guarantee covers the workmanship for a full year after the final day.
