Shingle Roof Replacement in San Antonio, TX

Swapping shingles isn't the same thing as replacing a roof. A real shingle roof replacement rebuilds every layer above the rafters, and our crews do it in the same order whether it's a 1,400 square foot ranch in Harlandale or a two-story in Stone Oak.

1. Tear-off. Shingles, felt and nails all come off, down to bare decking. Plants and the AC unit get tarped before that starts.
2. Decking check. We walk every sheet, and anything soft, delaminated or rotted is cut out and replaced. Our roof decking replacement page shows what we're looking for.
3. Drip edge and ice-and-water shield. Metal drip edge on the eaves and rakes. Self-adhered membrane in the valleys and around each penetration.
4. Synthetic underlayment. We use it over felt on nearly every job, because it won't wrinkle in August and it holds up if a storm blows in before shingles are on.
5. Starter strip, shingles, ridge. Starter course at the eaves, field shingles nailed to the manufacturer's pattern, ridge cap over a ridge vent so the attic breathes.
6. Flashing and boots. New pipe boots, new step flashing at walls and chimneys, vents sealed. Cheap roofs reuse old flashing, and that's usually where they start leaking.
7. Cleanup. Debris hauled off, gutters cleared, magnet sweep for nails.

Something local to know: the City of San Antonio treats a re-roof that keeps the same pitch as an over-the-counter permit. We pull it for you. Shingles are just part of our roof replacement work, which covers metal and low-slope roofs too.

We get asked this on almost every estimate.

3-tab shingles are one flat layer with two cutouts, so each strip looks like three tabs. Most 1970s to 1990s tract homes around San Antonio have them. They're lighter, cheaper to make, and they lie flat without a shadow line. Wind is their weak spot. A standard 3-tab is rated for around 60 mph, and the tabs lift and crease in our spring gusts.

Architectural shingles, which you'll also hear called dimensional or laminated, bond two layers of asphalt and fiberglass into a single thicker shingle. Nailed to the right pattern, that extra mass gets wind ratings of 110 to 130 mph. They also last longer in Texas heat and give you the layered, wood-shake look you see on newer builds in Alamo Ranch and Timberwood Park.

For a house you actually live in, we'd go architectural almost every time. 3-tab fits a rental or a detached garage, where the cheapest material wins and you're planning to sell soon. Has your roof taken hail before? Ask about Class 4 impact-resistant lines. Owens Corning and GAF both make them, and some Texas carriers give a premium discount for Class 4, so check with your agent first. Our asphalt shingle roofing page goes further into shingle types, colors and reflective options.

We're veteran owned and based in San Antonio, with crews working all over the city and the rest of Bexar County. Charlie Carreon, our owner, has 30 years in the trade, and many crews have worked alongside us for over 20. It shows up in small things. Straight courses. Six nails per shingle in the high-wind zone. Flashing tucked under the siding, where it's supposed to go.

We only use American roofing brands, and Owens Corning and GAF are the shingle lines we prefer, since both have held up across the 2,800+ projects we've done in the region. You won't see off-brand bundles from the back of a lot on our trucks.

Hail brings in a lot of our calls. On April 12, 2016, 4.5 inch hail fell on Helotes in what became the costliest hail event in Texas history at the time. In April 2021, Hondo got a Texas-record 6.4 inch stone while another cell moved east through San Antonio along I-10. And in 2025, Texas led the country with 902 major hail events. If your shingles are bruised or losing granules, our hail damage roof repair team will tell you plainly whether a repair will do or it's time to replace. If it's a replacement, our in-house former insurance adjusters bring 30+ years of claim experience: they meet your adjuster on the roof, document every slope and write the supplement when the first scope leaves out decking, drip edge or code items. The six steps are on our insurance claims page.

From Alma T.'s Google review: "Our entire roof was replaced after the initial inspection of insurance adjuster and Texas-RRR. Materials were ordered promptly and once the work began, it was nonstop until the job was completed. The roof looks great!!"
