Fast, Reliable Roofing Company Across Leon Valley
Roofing work in Leon Valley has to account for two things: homes built mostly between the 1960s and 1980s, and weather that swings from humid heat to sudden hail. Those older ranch homes often sit under original decking and flashing that were never designed for today’s wind-rated products. That means a roof inspection here is not a formality. It is the difference between catching a soft deck before the next storm and discovering it after water is already inside.
Our crews know the neighborhoods, the lot patterns, and the roof profiles across Leon Valley. We know which north-facing slopes collect the most hail impact and which 1970s additions hide unvented low-slope sections. Call (903) 354-7802 to schedule a free estimate, and we’ll send a background-checked, uniformed technician who will walk the roof with you before any work is discussed.
Why Birchbark Roofing San Antonio Is Leon Valley’s Preferred Roofing Company
Homeowners in Leon Valley tend to ask the same questions we have answered for years: will the decking hold the new fasteners? Is the existing drip edge reusable or should it go? What happens when a 1978 ranch has one low-slope carport roof and one standard-pitch main section? The answer is always the same: the written price comes first, and it reflects what the roof actually needs, not what is cheapest to quote.
Erik Lindgren, who leads Birchbark Roofing San Antonio, is part of the Roofing Company team that has been with the Cedarwell family of roofing businesses since 2000. Every job is covered by the 365-Day Done Right Promise. If something is not right, we make it right. That is stamped on every roof repair and replacement we perform in Leon Valley.
Our crews cover Leon Valley regularly. A live person answers calls 24 hours a day, seven days a week, including nights and weekends. When you call after a spring hailstorm, you are not waiting on a call center or a voicemail. You get a person, and that person can start scheduling your inspection.
Styles & brands we work with






Roof Inspection in Leon Valley
A roof inspection in Leon Valley should be specific to what these older homes actually do under stress. Original 1960s – 1980s ranch roofs often have 1×6 board decking, not plywood. That matters: a wind-rated shingle installation requires full nail penetration into solid wood, and if the boards are cracked, cupped, or rotten, the shingles will not hold to the 130 mph wind rating. Our inspections check deck condition board by board before anyone talks about shingle brands.
Most roof inspections in Leon Valley run between $150 and $350. If the inspection turns into a repair estimate, that inspection fee is credited toward the work. The written price comes before anything is touched. You will see exactly what was inspected, what failed, and what it costs to fix.
What the inspection covers on a 1970s ranch
We check the obvious: missing granules on 3-tab shingles, lifted edges, nail pops, cracked pipe boots, and deteriorated flashing at chimneys and valleys. But on Leon Valley homes, we also check what older roofs hide: attic ventilation, deck board condition, and whether the existing underlayment is still doing anything. Many of these homes were originally roofed with stapled 3-tab over felt. That worked fine for 1975. It does not work for a 2026 hail season.
When Leon Valley homeowners call us most
Two patterns show up consistently. The first is after a spring or fall hailstorm, when homeowners notice granules in the gutters or neighbors getting roof replacements. The second is before a roof gets listed for sale. Many Leon Valley homes are changing hands between first and second owners, and buyers are asking for inspection documentation that a wind-rated installation actually happened. We provide that in writing.
Commercial Roofing in Leon Valley
Commercial roofing in Leon Valley is typically low-slope, and many commercial buildings share the same construction era as the residential stock: built-up roofing over board decking, original drain lines, and flashing that has been patched rather than replaced. Low-slope failures do not announce themselves with a missing shingle. Water ponds, the membrane separates, and by the time a ceiling tile stains, the deck is already saturated. We inspect the entire assembly, not just the surface.
Commercial roof inspections and small repairs in Leon Valley generally start around $400 and go up based on square footage and access. Full commercial replacements vary widely depending on the system selected. We walk the roof, take core samples, map the ponding areas, and write a line-item price for the repair or replacement. That price is fixed. No change orders.
Flat and modified-bitumen systems for Leon Valley’s older buildings
Many Leon Valley commercial properties have near-flat sections that need a properly installed modified-bitumen or single-ply membrane, not a steep-slope product forced onto the wrong pitch. We install systems that carry the wind and hail ratings appropriate for this part of Bexar County. The right system is the one that matches the existing deck structure, drainage path, and Texas sun exposure.
Drainage and decking on older commercial roofs
Old commercial roofs in Leon Valley often fail at the drains first. Debris blocks them, water backs up, and the added weight stresses the deck. We inspect drain lines, scuppers, and edge details during every estimate. If the deck needs selective replacement, that is in the written price on day one, not a note from the crew halfway through the job.
Trusted Brands We Service in Leon Valley
We work with materials from GAF, CertainTeed, Owens Corning, and others. Our most common installation for Leon Valley ranch homes is GAF Timberline HDZ architectural shingle over full synthetic underlayment, with ice and water shield at valleys and penetrations. The HDZ line carries a 130 mph wind rating when installed to manufacturer specifications. That rating only holds if the deck is solid and nailed correctly, which is why decking is always part of the conversation here. We stock local parts and common flashings for older Leon Valley roof profiles, so repairs are not delayed waiting on a warehouse across town.
Common Roofing Company Problems We See in Leon Valley Homes
- 3-tab shingles near the end of their life. Original 1970s and 1980s roofs in Leon Valley are often on their first or second layer of 3-tab. Once the granules go, the asphalt underneath bakes in the Texas sun and the shingles become brittle and blow off in the first strong wind.
- Reused flashing causing leaks. Some bids reuse the original drip edge and pipe flashings to save a few hundred dollars. On a 1978 ranch, those pieces are already 40-plus years old. New shingles over old flashing means leaks the first time a Leon Valley thunderstorm sits over the house. We replace flashings on every full roof.
- Low-slope sections treated as steep pitch. Many ranch homes have carport or patio sections that are nearly flat. Architectural shingles are not rated for those slopes. That area needs self-adhered or modified-bitumen transition details. Miss that detail and water will get in regardless of what shingle you pick.
- Rotten deck boards hidden under old shingles. The 1×6 board decking on older Leon Valley homes often fails at eaves and valleys. When decking is omitted from the bid, the crew nails new shingles into soft wood. After the next hail event, the claim gets complicated because the installation was never wind-rated. We inspect and price deck replacement up front.

FAQs About Roofing Company in Leon Valley
Check for granule loss, lifted shingle edges, and any soft spots in the eaves or valleys. Those are the first signs that the shingles and decking will not survive another Leon Valley hailstorm. But the most important check is an attic inspection: look for dark staining on the deck boards, which signals water has already entered. We will do a full board-by-board deck inspection and give you a written report with photos. Call (903) 354-7802 to schedule it.
Yes. Full roof replacements in Leon Valley require a permit, and the permit inspection verifies the fastening pattern, underlayment, and edge details against current wind-load requirements. We pull the permit, schedule the inspection, and provide documentation of the full installation, including decking replacement, to both the city and your insurance carrier. A permitted, documented installation is the standard we hold for every job in Leon Valley.
After a hailstorm, an insurance adjuster will look for evidence that the roof was installed to current wind-rating standards. That includes full nail penetration into solid decking, synthetic underlayment with proper laps, and ice and water shield at valleys and penetrations. If any of that was skipped, a claim can be reduced or denied, even if the shingles themselves are new. Documented compliance is part of what you get with our written estimate and final walkthrough.
No. Architectural shingles are rated for slopes of 3:12 or steeper. A nearly flat or low-slope carport roof needs self-adhered or modified-bitumen roofing in that section, with proper transition flashing where it meets the main roof. Many of the 1960s – 1980s ranch homes in Leon Valley have these low-slope additions, and they fail the way flat roofs fail: water ponds and works its way under the shingle laps. We price and install the low-slope section as its own system, not as an afterthought.
A “square” is 100 square feet of roof area. Ask whether the bid price includes decking at actual condition, new drip edge, new flashings, disposal, and the permit. Many low bids in Leon Valley exclude rotten deck board replacement, reuse old flashings, or skip the permit line. Then the change order comes after tear-off. Our written price includes every one of those items, and the number does not change once work starts. Call (903) 354-7802 to get your square count and a real line-item estimate.
Wind-Rated Installation: What Leon Valley’s Older Ranch Homes Actually Need
Leon Valley’s 1960s – 1980s ranch homes often carry a specific structural quirk: low-slope built-up roofs over original 1×6 board decking. Wind-rated shingle installation on those boards requires full nail penetration into solid wood, not the code-minimum stapling that many of these homes received at original construction. Before any manufacturer will honor a 130 mph wind warranty, the deck has to be solid. Many older decks in Leon Valley need selective board replacement at eaves, valleys, and around penetrations. That is not an upgrade. It is the only way the wind rating is real.
On Timberhill Drive, we replaced a wind-lifted 3-tab roof after a spring hailstorm exposed granule loss and lifted shingles along the north slope. Our crew replaced deteriorated decking, installed GAF Timberline HDZ architectural shingles with full synthetic underlayment, ice and water shield at valleys and penetrations, and a new ridge vent, matching the original 1980s ranch profile while meeting current wind-load requirements. That is the standard we bring to every Leon Valley roof.
What to Expect From a Birchbark Roofing Visit in Leon Valley
Before anyone climbs onto your roof, you will know who is at your door. Our technicians are background-checked and uniformed. They wear shoe covers inside your home and lay drop cloths through hallways and entryways when accessing the attic or interior areas. If your dog needs to stay inside during the work, we coordinate the door schedule with you. Where there is a product choice, we use pet-safe options. At the end of the job, you receive a photo of the completed clean-up before the crew leaves. That is the Cedarwell Care Promise, and it applies to every visit in Leon Valley.
The name Birchbark comes from one of the first roofing materials ever used: birch bark, light and tough, made to shed water. The material has changed. The job has not. Keep the water out, and leave the home cleaner than we found it.
