Fast, Reliable Roof Replacement Across Kirby
A full roof replacement in Kirby typically runs between $9,800 and $16,500 for a standard single-family home, depending on whether your original decking passes today’s wind-load inspection. Most Kirby jobs take two to four working days once materials are on site. If you’re dealing with hail damage or an aging roof that’s starting to fail, call (903) 354-7802 for a free written estimate before you commit to anything.
We work throughout Kirby, from the older ranch homes near Ackerman Road and Binz-Engleman to the newer pockets around the 78209 corridor. Our Roof Replacement team knows what these roofs are up against: spring hailstorms, summer UV that bakes shingles brittle, and original decking that wasn’t built for the wind-load rules we follow today. The estimate you get from us is a fixed written price, in dollars, before any work starts. Not a ballpark. Not a handshake.
If you’re reading this because a storm just tore through Kirby, or because your roof is pushing 25 years old and you want it handled before the next one, you’re in the right place. There’s a real answer to what this costs and what it should include. Let’s get into it.
Why Birchbark Roofing San Antonio Is Kirby’s Preferred Roof Replacement Company
We’re part of the Cedarwell family of independently owned roofing businesses, and we’ve been doing this work since 2000. What that means for a Kirby homeowner is simple: a written price before the first shingle comes off, a 365-Day Done Right Promise on every replacement, and a crew that treats your house like a home. Shoe covers at the door. Drop cloths through the hallway. A photo of the completed clean-up before the crew leaves your driveway.
Erik Lindgren leads our team, and he’s built the way we work around one idea: roofers should prove their care in writing, not ask you to trust a handshake. That’s why the Cedarwell Care Promise is stamped on every job. Clean up like it’s our own home. Ask before we move or touch anything. Respect your family’s time and quiet hours. Explain the price before the work begins. It’s not marketing language – it’s the checklist our crews actually follow on every Kirby job.
We answer the phone with a live person 24 hours a day, 7 days a week. When you call (903) 354-7802, you won’t get a voicemail tree or a next-business-day callback. You’ll get someone who can answer questions about Kirby’s wind-load code, schedule an estimate, and tell you exactly what to expect from the first nail to the final magnet sweep.
Styles & brands we work with






Reroofing in Kirby
Reroofing in Kirby usually means tearing off the old shingle layer down to the decking, inspecting that decking against current wind-load requirements, repairing or replacing what fails, and installing a new roofing system rated for 130 mph uplift. The cost for a full reroof on a typical Kirby ranch home runs between $9,800 and $14,200, and most homeowners take two to three working days from tear-off to final inspection.
When to Reroof Instead of Patch
If your Kirby home still has its original 1960s composition shingles, patching is a temporary fix at best. Granule loss from South-Central Texas sun, lifted shingle edges from spring winds, and water staining at the eaves all point to a roof that’s outlived its design. A reroof replaces the entire system so the new shingles, underlayment, and decking work together as one wind-rated assembly.
What a Kirby Reroof Includes
A proper reroof in Kirby includes a full decking inspection before any new material goes down. If the original plywood fails, we replace it and document every sheet. Then we add ice and water shield at the eaves and valleys, install your shingles with a six-nail pattern, and photograph the whole process. You see the same photos the city inspector sees.
Flat Roof Replacement in Kirby
Flat roof replacement in Kirby costs more per square foot than pitched roof work, typically $12 to $18 per square foot depending on the system, and that’s because low-slope and flat sections demand materials and installation methods that shingle crews often get wrong. Many of Kirby’s older homes have a flat carport, addition, or patio section that was originally built with methods that don’t meet today’s wind and water-shedding standards.
Why Flat Sections Fail First
Flat and low-slope sections on Kirby homes collect water longer, and wind-driven rain pushes under seams that would be protected on a steeper pitch. When a roofer skips the peel-and-stick underlayment or uses the wrong fastening pattern, the first hailstorm finds the weakness. We replace flat sections with systems rated for Kirby’s hail-prone corridor and document the installation for any future insurance conversation.
What We Use on Kirby Flat Roofs
Depending on the roof and your budget, we install TPO, modified bitumen, or coated systems from manufacturers like GAF and CertainTeed. Each gets the same treatment: full decking inspection, proper underlayment at transitions, and a written price that matches the final invoice. No change orders. No surprises after the crew starts.
Trusted Brands We Service in Kirby
We stock and install materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, and Tamko, which means we’re not tied to one manufacturer’s product line. For Kirby homes, that matters because different roof designs call for different systems. Architectural shingles from Owens Corning or GAF handle the steep main roof beautifully, while a flat addition might need a TPO or modified bitumen system from a different line. We carry the local parts and accessories to keep a Kirby job moving without waiting on a distributor in San Antonio, and we know which products carry the 130 mph wind ratings this area requires.

AfterCommon Roof Replacement Problems We See in Kirby Homes
- Original 1960s plywood decking failing wind-load inspection. Kirby’s ranch homes from that era used thinner decking and fewer fasteners than today’s code requires. When we tear off the old shingles, we often find missing nails and water damage at the eaves that you’d never see from the ground.
- Hail damage hidden under old shingles. Large hail cracks the shingle mat and loosens the seal strip, but the damage sits under the shingle where it can’t be seen. A thorough inspection after a Kirby hailstorm often finds damage that a quick visual walkaround misses.
- Low-slope sections leaking at the transition. Many Kirby homes have a flat carport or patio roof tied into the pitched main roof. If the transition isn’t flashed and sealed correctly, wind-driven rain gets in there during spring storms.
- Improper nailing patterns voiding the wind warranty. We see roofs in Kirby where the shingles themselves are rated for 130 mph but the roofer used four nails instead of six. That voids the manufacturer’s wind rating and fails Kirby’s uplift inspection. The shingles look fine from the ground, but the roof isn’t.
Pricing for Roof Replacement in Kirby, TX
Here’s the honest math for Kirby. A standard asphalt shingle roof replacement on a 1,500 to 2,200 square foot ranch runs $9,800 to $14,200. If your decking needs significant replacement, add $1.50 to $3 per square foot of affected area. A flat roof section runs $12 to $18 per square foot. Architectural shingles add roughly 15 to 20 percent over three-tab, and upgraded underlayment or ice and water shield adds $0.80 to $1.40 per square foot. You’ll see your exact number in writing before any work begins, and it won’t change unless you change the scope. Call (903) 354-7802 to schedule a free estimate.

FAQs About Roof Replacement in Kirby
You won’t know for certain until the old shingles come off and we can inspect the decking from above. What you can do before that is ask for a written quote that explicitly includes decking replacement at a set price per square foot, so you know your worst-case number. Our Kirby quotes always include that line item. If the decking passes, you pay nothing for it. Call (903) 354-7802 and we’ll walk you through exactly what we look for.
Yes. Kirby’s building code and the manufacturer’s installation instructions both require ice and water shield or equivalent underlayment at the eaves, valleys, and any low-slope section. A quote that leaves it out is cheaper on paper but leaves your attic exposed to wind-driven rain. We include it on every Kirby replacement, on every low-slope section, and we photograph it before the shingles go on.
Look for three things: a six-nail fastening pattern on architectural shingles, ice and water shield at eaves and valleys, and a written line item for decking inspection and replacement. If those three aren’t in the quote, the roof isn’t wind-rated as a system, no matter what the shingle packaging says. Ask the roofer to show you the nailing pattern in writing. We put it in every Kirby quote.
Insurance companies in the Kirby area typically accept a combination of photos showing the decking condition before recovery, photos of the six-nail pattern, the ice and water shield installation, and the city’s final inspection report noting compliance with current wind-load code. We provide all of that as standard practice on every Kirby replacement, not as an add-on. That documentation makes future hail claims faster to process.
Yes, generally. Flat and low-slope sections run $12 to $18 per square foot compared to $4.50 to $6.75 for pitched shingle sections, because the materials and installation methods are different and the code requirements for sealing and uplift resistance are stricter. The good news is that fixing the flat section correctly now means you’re not replacing it again after the next storm. Call (903) 354-7802 for an exact quote on your flat section.
