Trusted Roof Replacement for San Antonio Homeowners

Roof Replacement - San Antonio typically runs between $8,500 and $18,000 for a standard asphalt shingle roof on a 1,500 to 2,500 square foot home, with most projects completed in 1 to 3 days once materials arrive. That’s the range we see across Alamo Heights, Terrell Hills, Castle Hills, and the surrounding neighborhoods every week. Birchbark Roofing San Antonio has been part of the Cedarwell family of roofing businesses since 2000, and every replacement we do carries a written price before work begins and our 365-Day Done Right Promise.

San Antonio’s climate punishes roofs in a very specific way. Intense UV exposure from May through September bakes shingle granules loose, while sudden spring hailstorms and the occasional freeze-thaw cycle in January and February create the kind of stress that turns a 20-year roof into a 12-year roof. When you call us about a replacement, we start by looking at the roof with that local weather history in mind, not just a generic checklist.

Key Takeaways:

• Most full roof replacements in San Antonio run $8,500-$18,000 depending on square footage and material grade
• You get a written price in dollars before any work starts, never an estimate you have to trust
• Background-checked, uniformed technicians do the work; shoe covers and drop cloths protect your floors
• A photo of the completed clean-up is taken before the crew leaves your property
• Every replacement is covered by the 365-Day Done Right Promise

Roof Installation

Roof Installation means putting a brand-new roofing system on a home that has either never had one, or whose existing roof has been fully torn off down to the decking. In San Antonio, roof installation pricing typically falls between $9,000 and $20,000, with the spread driven by square footage, material choice, and how much decking repair the home needs underneath. At Birchbark Roofing San Antonio, our roof installation work always begins with a written price, so families in Alamo Heights and Terrell Hills know exactly what they are approving before a single shingle comes off the truck.

Tear-Off and Decking Inspection

We remove every layer of old roofing, not just the top layer. This lets us inspect the decking underneath for rot, water staining, or termite damage that a layover would hide. If we find soft spots, we show you photos and give you a new written number before replacing any wood.

Underlayment and Water Barrier

San Antonio homes get hammered by wind-driven rain along the I-10 corridor. We install a full synthetic underlayment and ice-and-water shield at all valleys, eaves, and penetrations, then verify the barrier is continuous before the first shingle goes down. This is the layer that actually stops leaks, and we treat it that way.

Roof Replacement Contractor

Roof Replacement Contractor is the role you want filled by a company that pulls permits, carries insurance, and stands behind the job in writing, not by a crew working out of a pickup truck. A roof replacement in San Antonio requires someone who knows the city’s wind rating requirements and the specific ways that South Texas heat deteriorates underlayment. Birchbark Roofing San Antonio is that contractor: background-checked, uniformed technicians, a written price before any work starts, and Erik Lindgren’s phone number ringing to a live person every time you call.

Written Price Before Work Begins

You will not get a verbal ballpark from us and a surprise later. We put the full project cost in writing, in dollars, before anything is torn off. If the decking underneath turns out to need work we couldn’t see before tear-off, we stop, show you, and give you a new written number before proceeding.

Clean-Up Photo Before We Leave

Roofing creates debris, no way around that. What sets a professional roof replacement contractor apart is what happens to that debris. Our crew runs a magnetic sweeper for nails, clears all material from landscaping beds, and takes a photo of the finished clean-up that we show you before we pull out of the driveway.

Asphalt Shingle Roof Replacement

Asphalt Shingle Roof Replacement is the most common roof replacement we do in San Antonio, typically running between $8,500 and $15,000 for a standard single-story home, with architectural shingles from GAF or CertainTeed adding a few thousand more. Homeowners choose asphalt because it handles the South Texas sun well when installed correctly and sits comfortably within most budgets. Birchbark Roofing San Antonio works with shingles from GAF, CertainTeed, Owens Corning, and several other approved brands, and we will walk you through the difference between a 3-tab and an architectural shingle in plain English, not manufacturer jargon.

Architectural vs. 3-Tab Shingles

Architectural shingles are thicker, carry higher wind ratings, and hold their granules longer in San Antonio’s UV-heavy summers. 3-tab shingles cost less upfront but tend to show age faster here. We show you samples of both and let the written price guide your decision, not our commission.

Ventilation and Attic Heat

A shingle roof replacement that ignores attic ventilation will fail early, especially in neighborhoods like Kirby and Leon Valley where attics hit 140 degrees in August. We check ridge and soffit ventilation as part of every replacement and include necessary upgrades in your written price. That’s the difference between a roof that lasts and one that cooks itself from underneath.

New Roof Installation

New Roof Installation applies to new construction, additions, or cases where the existing roof structure is being replaced entirely rather than just resurfaced. Costs in San Antonio generally start around $12,000 and can reach $30,000 or more depending on roof complexity, steepness, and material. Birchbark Roofing San Antonio handles new roof installation for home additions in Live Oak and Selma just as carefully as we handle full replacements on older homes in Castle Hills, and the same rules apply: written price first, clean-up photo before we leave.

New Construction and Home Additions

If you are adding a room or building a new home, the roof installation is part of the structural timeline. We coordinate with your general contractor or builder so the roof is in place when framing and electrical inspections require it. Our crews work clean on active construction sites and our written price stands regardless of changes elsewhere on the project.

Storm Damage Reroofs

When a hailstorm in Lackland AFB or Windcrest totals a roof, the insurance claims process can feel like a second job. We document all damage with photos, meet your adjuster on-site, and provide a written price that lines up with your claim scope. You should not have to argue with your insurance company; our documentation speaks for itself.

Reroofing

Reroofing is the process of removing the existing aged roof and installing a new one in its place, and in San Antonio it typically costs between $9,000 and $18,000 for a full tear-off and replacement. Some companies offer a layover, where they nail new shingles over the old ones, but we do not recommend that route in South Texas heat, where trapped moisture and double weight shorten the new roof’s life. Birchbark Roofing San Antonio recommends a clean tear-off for almost every home, and the price you see before work begins already includes disposal of the old material.

Full Tear-Off vs. Layover

A layover hides problems and saves a few thousand dollars upfront while cutting years off the new roof’s life. A full tear-off shows you exactly what is under the shingles and gives us a clean surface for underlayment and fastening. We show you the difference in writing, and most homeowners pick the tear-off once they see the logic.

Protecting Landscaping and Exterior

San Antonio homes in Alamo Heights and Terrell Hills often have mature landscaping that took decades to grow. Before any reroofing begins, we place tarps over planting beds, move patio furniture away from the fall zone, and use magnetic sweepers to pull roofing nails from the lawn. Your written price includes all of this; it is not an add-on.

Flat Roof Replacement

Flat Roof Replacement is a different animal entirely, and in San Antonio it typically costs between $10,000 and $22,000 depending on the membrane system, drainage needs, and whether the roof is walkable or equipment-mounted. Many older homes in Castle Hills and Leon Valley have flat-roofed additions, porches, or carports that need specialized materials, not shingles. Birchbark Roofing San Antonio installs flat roof systems from GAF and CertainTeed, and we pay special attention to the thing that kills most flat roofs in this city: standing water after a heavy summer thunderstorm.

Membrane Options for South Texas Heat

TPO membrane reflects heat, which matters in San Antonio where flat roofs face direct sun for fourteen hours in June. Modified bitumen costs less and handles foot traffic well, but tends to absorb more heat. We walk you through both and price both in writing before you choose.

Drainage and Ponding Water

A flat roof that holds water after a rain is a flat roof on a timer. We verify that existing drains and scuppers are clear, size them to San Antonio’s heaviest storm events, and slope crickets where needed to keep water moving. If your current flat roof puddles for more than 48 hours after rain, that is something we fix during replacement, not after another leak appears.

Brands We Service

We work with materials from GAF, CertainTeed, and Owens Corning on most of our San Antonio roof replacements. GAF Timberline HDZ is a solid architectural shingle choice for South Texas wind and sun, with a strong warranty structure that transfers if you sell your home. CertainTeed Landmark shingles offer a broader color palette, which matters in historic neighborhoods like Alamo Heights where a specific look might be required. Owens Corning Duration shingles use a proprietary granule bond that holds up well against the UV intensity we get from May through September.

If your roof was originally installed with shingles from any of these brands, we can match the profile and color. If you are looking at switching brands, we will show you samples and explain the real differences that matter in San Antonio’s climate, not just the marketing claims. Whether you have GAF, CertainTeed, Owens Corning, or any other shingle brand on your roof right now, we can replace it and improve it.

Signs You Need a Pro Right Now

• Granules collecting in your gutters or at downspout exits. After a few San Antonio summers, shingle granules loosen and wash down. Bare spots on shingles mean the UV protection is gone, and the roof is aging faster than it should. Call us for an inspection before those bare spots become leaks.
• Water stains on ceilings or in the attic after a hard rain. A stain means water got through the roof and traveled to the drywall. By the time you see the stain, the leak has likely been active for weeks, and the decking underneath may already be soft.
• Shingles curling at the edges or lifting at the corners. Curled shingles catch wind, and after a strong thunderstorm on the northeast side near Converse, they can tear off entirely. Lifting shingles are an invitation for water intrusion, and they tell you the roof’s fastening system is failing.
• Daylight visible through the roof boards when you’re in the attic. If you can see light coming through, water can get through too. This is not a repair situation; it is a replacement indicator, and we will show you exactly what we see with photos from the attic.
• Your roof is over 15 years old and has never been inspected. Most asphalt shingle roofs in San Antonio last 15 to 20 years, less if they have taken hail hits. An inspection costs you nothing, and if the roof has life left, we will tell you that too.

Our Process, Step by Step

1. 1
   Initial Walkthrough and Written Price. Erik Lindgren or one of our senior techs walks the roof, checks the attic, and documents everything with photos. You receive a written price in dollars that covers the entire scope before any work is approved.
2. 2
   Material Selection and Scheduling. We bring shingle samples and color charts to your kitchen table, then schedule your replacement around your family’s schedule. If the dog needs to stay inside, we coordinate the door schedule with you; we use pet-safe products where there is a choice.
3. 3
   Protection Before Tear-Off. Shoe covers go on at the door. Drop cloths run through the hallways. Tarps go over landscaping and patio areas. The crew knows exactly what is to be protected inside and outside before the first shingle comes off.
4. 4
   Tear-Off, Inspection, and Installation. We remove all old material down to the decking, inspect for rot or structural issues, and then install new underlayment, flashing, and shingles according to manufacturer specifications. We also inspect the ventilation system to make sure the new roof breathes correctly, especially in attics that run hot in Live Oak and Selma.
5. 5
   Final Clean-Up and Photo Verification. We run a magnetic sweeper for nails, clear debris from landscaping beds, and take a photo of the completed clean-up. You see that photo before we leave, and your 365-Day Done Right Promise is active from that moment.
