Fast, Reliable Roof Replacement Across San Antonio
Roof replacement in San Antonio typically runs $8,500 to $16,500 for a standard single-family home with architectural shingles, and most full tear-offs take 2 to 4 days once materials are on site. That’s the honest range we quote, and we put it in writing before the first shingle comes off. We’re Crestview Roofing Co San Antonio, led by Dylan Pace, and our crews work neighborhoods from Alamo Heights to Stone Oak every week. We know what San Antonio roofs look like when they come apart, because we open them up here, not from a call center three states away. Call (361) 209-8857 and we’ll schedule a free estimate with a real arrival time you can track.
Why Crestview Roofing Co San Antonio Is San Antonio’s Preferred Roof Replacement Company
San Antonio homeowners call us because we give them something most roofers won’t: visibility. Before any work starts, you get a written price. While the crew is on your roof, you get photo updates. When the job is done, you get a digital invoice sent by text. That’s The Relay Standard, and it’s how we run every job in every San Antonio neighborhood we serve. No “we’ll see what we find” pricing. No invoice that doesn’t match the quote. The number Dylan Pace writes down is the number you pay.
We also carry the 365-Day Done Right Promise on every repair. If a covered repair fails within a year, we come back and fix it free. Not prorated, not negotiated, not “that’s normal wear.” Free, in writing, included with every job. That matters in San Antonio, where a spring hailstorm can undo a poor repair in one afternoon. Our customers in Universal City, Helotes, and across the metro trust that promise because we back it with our name and our work.
We install manufacturer-backed shingles from Owens Corning, IKO, Atlas, and Tamko, among others. Material quality is never negotiable here. You’ll know exactly who is arriving at your home, what they’re installing, what it costs, and what it looks like when they finish. A live person answers our phone 24/7. That’s not a marketing line; it’s how we operate.

Flat Roof Replacement in San Antonio
Flat Roof Replacement in San Antonio is a different animal from the sloped shingle work most people picture. Many San Antonio homes built mid-century or used as additions, carports, and porches have flat or low-slope sections roofed with modified bitumen, TPO, or old built-up layers that bake in the Texas sun. On a flat roof, water doesn’t run off the way it does on a 6:12 pitch, so the membrane, flashing, and drainage details do all the heavy lifting. A flat roof replacement here typically runs $9,000 to $18,000 depending on size, decking condition, and membrane type. If your flat section has ponding water after a San Antonio downpour, cracked seams, or bubbles in the membrane, it’s time to look at it before decking rot sets in.
Signs Your Flat Roof Needs Attention
Ponding water that sits for more than 48 hours after rain is a structural problem on a flat roof, not just a cosmetic one. San Antonio’s intense summer heat softens older membranes and accelerates seam failure. We check the roof drains, scuppers, and edge flashing first, because most flat roof leaks in this city start at transitions, not in the field of the membrane. Older built-up roofs inside Loop 410 often hide wet insulation under what looks like a decent surface. Once the membrane is peeled back, the truth shows up. That’s why our written quote includes a per-sheet decking allowance, so you know what a worst-case discovery will cost before we open anything.
Flat Roof Options for San Antonio Homes
We install TPO, modified bitumen, and coated metal systems for flat and low-slope sections, matched to the roof’s pitch and the home’s age. San Antonio’s freeze-thaw cycles are less common than hail, but they still matter: any standing water that freezes expands and opens small cracks. A properly installed flat roof here needs positive drainage, not just a new membrane over the same low spots. Our Roof Replacement team includes flat work as a standard part of the estimate, not an afterthought.
Roof Replacement Contractor in San Antonio
A Roof Replacement Contractor in San Antonio should be able to explain the difference between an overlay and a tear-off, why decking inspection matters, and what the city inspector will check before any new roof passes. We walk every San Antonio roof before quoting, and we write the scope in plain English, not roofing shorthand. A full tear-off and replacement on a typical 2,000-square-foot San Antonio home runs $10,000 to $15,500 with architectural shingles, new underlayment, drip edge, and standard flashing. That includes the permit and the inspections. If the roof is bigger, steeper, or has three layers to remove, the number moves from there, and we tell you exactly why before you commit.
What to Expect During Your Replacement
We strip the old roof down to the decking, inspect every sheet of plywood or OSB, and replace anything rotted or delaminated. In San Antonio, particularly inside Loop 410, we find decking damage more often than not, because decades of attic heat and the occasional roof leak have worked on the wood from both sides. You’ll get photos of what we found before we cover it back up. The permit inspection happens after the decking is exposed and before the new roof goes down, so the city inspector has full visibility. That’s not optional; that’s code, and we don’t cut corners on it.
Permits and Inspections
San Antonio requires a permit for roof replacement, and the inspection process is designed to catch exactly the issues we just described: bad decking, missing flashing, inadequate nailing. We pull the permit, schedule both the decking inspection and the final inspection, and stand with the inspector for the questions. If a code upgrade gets triggered, like adding ice and water shield in valleys or installing proper chimney flashing, we price it into your written quote up front, not as a surprise change order. Dylan Pace doesn’t sign off on a job until the inspection passes and you’ve seen the final photos.
Trusted Brands We Service in San Antonio
Crestview Roofing Co San Antonio installs and services shingles from Owens Corning, IKO, Atlas, and Tamko, so whatever your home’s architecture and budget call for, we can match it without pushing you to a single brand.

Material quality is never the place we save your money, because San Antonio’s hail and heat will expose a cheap shingle in one season.

AfterCommon Roof Replacement Problems We See in San Antonio Homes
- Three-layer shingle roofs inside Loop 410. Homeowners kept overlaying to save money, and now those roofs trap heat and put dead load on aging 1960s decking. San Antonio code requires a complete tear-off before any new roof can be installed over them. The plywood underneath is often delaminated from decades of attic moisture and needs partial redecking.
- Granule loss in Stone Oak after spring hail. Architectural shingles get granule-blasted but the underlayment stays intact, so homeowners wait. Then the next wind-driven rain comes, and leaks start at the valleys and pipe penetrations where the shingle’s protective surface is gone. We’ve replaced dozens of Stone Oak roofs that looked fine from the curb but were compromised at the transitions.
- Freeze-thaw damage at drip edge and valleys. Flash-freezing winter cold fronts followed by rapid thaw cause ice to back up under the drip edge of older San Antonio homes that have no ice and water shield. The fascia rots behind the gutter, and interior staining shows up months later. By then the rafter tails are going too. Older homes near downtown and in established neighborhoods like Jefferson and Beacon Hill are the usual suspects.
- Decking rot hidden under “good” shingles. A roof that looked serviceable from the street can hide soft plywood under the shingles, especially where a ridge vent was never installed and attic heat built for decades. We find this on 1970s and 1980s tract homes across San Antonio, where the original plywood is now 40 years old and the felt underlayment has turned to dust. The shingle was never the problem. The system under it was.

FAQs About Roof Replacement in San Antonio
Look at the edge of your roof along the rake or gutter line and count the shingle courses. If you see three distinct layers stacked, your roof has been overlaid twice, and San Antonio code will require a complete tear-off before any new roof goes on. Inside Loop 410, triple-layer roofs are common because previous owners saved money by overlaying. We’ll count the layers during a free inspection and tell you exactly what code requires. Call (361) 209-8857 to schedule a free estimate, and we’ll give you the answer in writing.
San Antonio code requires the roof decking to be exposed and inspected after the old shingles are torn off and before the new underlayment goes down. The inspector checks for rotted or delaminated plywood, proper nailing, and correct flashing at penetrations, valleys, and rakes. We schedule this inspection, stand with the inspector, and photograph everything for you. If the inspector flags something, we price the fix and get your written approval before we proceed. Call (361) 209-8857 if you’re planning a replacement, and we’ll walk you through the whole process at no charge.
Stone Oak sits in a hail corridor that gets hit in spring, and today’s architectural shingles lose granules when hail impacts at high velocity even if the shingle doesn’t tear. The granule layer is the shingle’s UV and impact armor, so repeated loss shortens roof life and exposes the asphalt to San Antonio’s intense summer sun. Once granules collect in your gutters and valleys, the roof is compromised even if there’s no visible leak. We offer free inspections throughout Stone Oak with photo documentation. Call (361) 209-8857 to schedule one before the next hailstorm hits.
Yes, and here’s exactly what we typically find: delaminated plywood from decades of attic heat and moisture, missing drip edge at the rakes, rotten fascia behind the gutters, and code-required flashing that was never installed. On a triple-layer roof, the sheer weight often stresses the decking. We write a per-sheet decking allowance into every San Antonio quote so you know what a worst-case discovery costs before we tear anything off. If we find something, we show you a photo and get your written approval before touching it. That’s how Dylan Pace runs every job. Call (361) 209-8857 for a free estimate with the allowances already in writing.
Older San Antonio homes built before ice and water shield became standard have vulnerable spots at the eaves, valleys, and dormer transitions. When a winter cold front drops freezing rain and then the temperature swings up fast, meltwater refreezes at the roof’s edge and backs up under the shingles at the drip edge. The water rots the fascia and rafter tails from the outside in, and staining often shows up on the ceiling only months later. We install ice and water shield in valleys and at all eave edges on every San Antonio replacement, which stops the cycle. For an inspection of your roof’s edge details, call (361) 209-8857. The estimate is free, and the written price won’t move once work starts.
