Kirby sits in the hail-prone corridor below San Antonio’s east side, which means storms roll through with large hail and straight-line winds that find every weak fastener and old deck board. We know the older streets here, the ones where original plywood decking from the Eisenhower and Johnson years is still up there.
Why Birchbark Roofing San Antonio Is Kirby’s Preferred Roofing Company Company
Homeowners around Kirby keep calling us back because we write down the price before anything starts and we photograph the cleanup before the crew leaves. That matters when you have kids tracking through the hallway and a dog who’s already nervous about the hammering. We put shoe covers on at the door, run drop cloths through the work path, and clear every nail and shingle scrap from the yard. Erik Lindgren, who leads our team, insists on it at every job, including the ones on Ackerman Road and the streets off Binz-Engleman.
We’ve worked on enough Kirby homes to know the difference between a roof that looks fine from the curb and one with decking that’ll fail the re-nailing inspection. Our background-checked, uniformed technicians have repaired hail-bruised shingles near Kirby Middle School and replaced low-slope sections over carports on the older streets. The documentation we leave with you, permit, inspection sign-off, and material spec sheets, is what the insurance adjuster and your mortgage company want to see.

Free Roof Estimate in Kirby
Our Free Roof Estimate in Kirby is a written, line-item price for the work your roof actually needs. When a Kirby homeowner calls us, we schedule a walk-through, inspect the roof surface, the decking condition, and the existing ventilation, then hand you a dollar figure before anyone picks up a hammer. No estimate means no obligation, and we never change the number unless you change the scope.
What the estimate covers
We walk the whole roof, not just the street-facing slope. We check shingle granule loss, flashing at the valleys and penetrations, decking deflection, and whether the existing nailing pattern meets current high-wind uplift requirements for Kirby’s wind zone. You get a written list showing materials, a start-to-finish schedule, and exactly where the crew will protect your floors and landscaping.
When to schedule one
After any hailstorm that drops stones bigger than a quarter, Kirby homeowners should have the roof looked at before the damage gets hidden by time and UV exposure. You don’t need to know if you’re filing a claim. You need to know what’s actually damaged. That’s what the estimate shows you.
Roofing Contractor in Kirby
Our Roofing Contractor crew in Kirby handles the full job, tear-off, decking corrections, underlayment, shingle or low-slope installation, flashing, ventilation, and cleanup. A Kirby homeowner needs this level of work when a patch is no longer safe, when the decking has been compromised by hail or moisture, or when the existing roof has reached the end of its service life. The cost depends mostly on decking condition and material grade.
Decking correction
Older Kirby homes frequently have 1/2-inch plywood decking on 24-inch rafter spacing. Current wind-load requirements for our area demand thicker decking or closer support. When we find it, we replace the affected sections, not the whole roof deck, and we document exactly what changed and why.
High-wind installation
We install shingles using the manufacturer’s high-wind nailing pattern, which on CertainTeed Landmark and GAF Timberline products means six nails per shingle instead of four. That’s not an upsell. In Kirby’s wind zone it’s the difference between a roof that stays put and one that peels open at the ridge during the next spring storm.
Trusted Brands We Service in Kirby
We work with materials from GAF, CertainTeed, and Owens Corning among others, and we can get specific SKUs fast for Kirby jobs because our supplier network runs through San Antonio’s east side. If you’re replacing a few hail-damaged CertainTeed Landmark shingles on a ranch house near Ackerman, we match the existing color and profile without making you wait three weeks for a special order. The written estimate tells you the exact product, the wind rating, and the warranty level before you sign anything.

AfterCommon Roofing Company Problems We See in Kirby Homes
- Hidden decking damage after hailstorms. Hail bruises the shingle mat from underneath, and the decking behind it often has hairline fractures that won’t show until the next big wind event. A visual curb check misses this. We check deflection with a moisture meter and physical inspection before quoting.
- Original 1/2-inch decking on 24-inch centers. Many 1950s – 1970s Kirby homes were framed to older code that allowed thinner decking than today’s wind-load tables permit. A cheap strip-and-shingle bid skips the decking conversation entirely. A compliant quote addresses it in writing.
- Low-slope and flat-roof sections with ponding water. Carports, additions, and porch roofs in Kirby often have slopes below 2:12, which means shingles are the wrong product there. We use modified bitumen or peel-and-stick membrane systems on those sections, and we tie the transition flashing correctly so water doesn’t back up under the shingle field.
- Missing or blocked ventilation. Intense Kirby summers bake attic spaces, and older homes often have ridge vents with no functioning soffit intake. That shortens shingle life dramatically. Any replacement quote from us includes a ventilation balance calculation, and we’ll note in writing if your current setup is starving the attic.

FAQs About Roofing Company in Kirby
Kirby follows the Texas Department of Insurance wind-load requirements for Bexar County, which for this area means shingles must be installed to meet a minimum wind uplift rating appropriate for our exposure. On a 1960s home with original decking, the shingle product itself is rarely the problem. The decking thickness and fastener pattern are. A compliant quote includes a decking verification step and a manufacturer high-wind nailing pattern, typically six nails per shingle, not four. We confirm the exact rating needed for your roofline during the free estimate. Call (903) 354-7802 to schedule one.
Usually not, if the decking is visibly degraded or if it doesn’t meet the current wind-load deflection limits for our area. Kirby inspectors enforce current code, not the code from when your house was built. If your decking is solid, some inspectors will pass it for a re-cover. If it’s soft, water-stained, or delaminating, it gets replaced before underlayment goes down. We check this during the free estimate and tell you in writing whether your deck will pass, so there’s no surprise at inspection. Call (903) 354-7802 for an exact quote.
Kirby requires a building permit for residential re-roofing, and the job must pass a final inspection. Beyond the city requirement, your insurance carrier will want the permit number, the signed inspection record, photos of the hail damage before tear-off, and a line-item invoice with the material specs. We photograph everything before, during, and after, and we give you all of it as a packet. If your adjuster has questions about wind-load upgrades we made to the decking, we document those too. Get a free written estimate at (903) 354-7802.
Shingles only work on slopes of 2:12 or steeper. Below that, water moves too slowly and will back up under the shingle laps. Many Kirby homes built in the 1950s and 1960s have carport, porch, or addition sections with low slopes, and those need peel-and-stick membrane or modified bitumen systems instead. A proper quote separates those sections line by line. A strip-and-shingle bid that puts shingles on a 1:12 slope will leak, usually at the valley transition where the two systems meet. Call (903) 354-7802 and we’ll inspect every section of your roof, including the flat parts.
Yes, in many cases, though the discount depends on your carrier and the specific wind mitigation features you install. The key documentation is proof of a high-wind nailing pattern, upgraded decking where needed, and a secondary water barrier at the eaves and valleys. We provide all of that in writing after the job passes inspection. You then submit it to your agent. We can’t promise a specific premium reduction, but we can promise you’ll have the paperwork your carrier asks for. Schedule a free estimate at (903) 354-7802.
