AfterFull Roof Replacement in San Antonio, TX
Full roof replacement in San Antonio means tearing off the existing shingles, underlayment, and sometimes the decking beneath, then installing an entirely new roofing system from the deck up. Most San Antonio homes need this roughly every 15 to 25 years depending on shingle type, storm damage history, and attic ventilation quality. At Crestview Roofing Co San Antonio, we give you a written price before any work starts, a live trackable arrival time, and before-and-after photos so you see exactly what got replaced. Call (361) 209-8857 to get your free estimate scheduled.
This is the biggest roofing investment most homeowners will make, and it’s also the one where surprises hurt the most. We built our full replacement service around removing those surprises entirely. The number on your written estimate is the number on your final invoice. If you’re weighing whether to repair or replace, our Roof Replacement & Installation in San Antonio page breaks down the full decision-making process.
When You Need Full Roof Replacement
Not every roof issue calls for a full tear-off. Patching can buy you time when damage is isolated. But San Antonio’s combination of hail, intense UV exposure, and rapid temperature swings accelerates shingle breakdown in ways that patch jobs can’t outrun. Here are the situations where we consistently recommend a full replacement:
- Shingle granule loss across the whole roof. If you’re finding grit in your gutters after every rain and the shingles look bald in patches, the protective surface is failing roof-wide. Replacement is cheaper than waiting for leaks to start.
- Multiple leaks in different areas. One leak is usually a flashing or puncture repair. Three or more leaks in separate sections of the house typically means the waterproofing layer has reached the end of its service life.
- Storm damage from hail or wind across large sections. San Antonio sees hailstorms that damage 40% or more of a roof’s surface. When damage is scattered across most slopes, spot repairs don’t make financial sense.
- Shingles curling, cracking, or lifting at the edges. This happens faster on San Antonio’s south-facing and west-facing roof planes, where afternoon sun cooks the shingles. Once curling is visible from the ground, the roof is typically within a few years of failure.
- Roof age past 20 years with visible decay. Even a roof that’s never leaked is aged. If you’re at year 18 or beyond and planning to stay in the home, replacing on your timeline beats replacing on an emergency timeline.
- Decking rot or sagging between rafters. If you can see waviness in the roof line or soft spots when walking the roof, the structural layer is compromised. A full replacement lets us replace rotted decking sections before they fail.
Our Full Roof Replacement Process
We run full replacements with the same visibility standard we apply to every job at Crestview. You’ll know who’s on your roof, when they’ll arrive, and what the work will cost before we ever swing a hammer. Here’s how it works:
- On-site inspection and written estimate. Dylan or a Crestview technician walks the roof, photographs everything, and gives you a written price. That price includes all labor, materials, tear-off, disposal, and any decking we can see needs replacing before we start.
- Pre-job documentation. Before tear-off begins, we photograph the existing roof from every angle. You get those photos. If the decking underneath is worse than expected, you’ll see the evidence with your own eyes before any change to the price.
- Tear-off and decking inspection. We strip old shingles, felt, and flashing down to the deck. Every sheet of plywood or OSB gets inspected. Rotted or water-damaged sections get replaced, photographed, and documented.
- New roofing system installation. We install new underlayment, drip edge, flashing at every penetration and valley, and your chosen shingle system from manufacturers like GAF, CertainTeed, or Owens Corning. Every layer goes down per manufacturer spec so the warranty stays intact.
- Cleanup and photo documentation. We run a magnetic sweep for nails, haul away all debris, and photograph the finished roof from the same angles as the before shots. You get a digital invoice by text, and the final price matches the written estimate unless you approved a change in writing during the job.
Full Roof Replacement Pricing in San Antonio
Full roof replacement in San Antonio typically runs between $8,000 and $18,000 for an average single-family home, depending on roof size, pitch, shingle grade, and decking condition. The largest cost driver is square footage, followed by tear-off complexity and whether any structural decking needs replacement. Here’s a closer look at what moves the number:
| Cost Factor | Typical Price Range in San Antonio | What It Covers |
|---|---|---|
| Architectural shingle tear-off and replacement | $4.50 to $6.50 per square foot | Full tear-off, underlayment, drip edge, standard flashing, 30-year architectural shingles |
| Premium shingle systems | $6.50 to $9.00 per square foot | Higher-grade products from CertainTeed or Owens Corning with extended wind ratings |
| Decking replacement | $65 to $90 per sheet | Replacing rotted or delaminated plywood or OSB discovered after tear-off |
| Steep or complex roof pitch | Adds 10% to 20% | Additional safety equipment and labor time on steep or multi-level roof lines |
| Flashing replacement (chimney, valley, wall) | $300 to $800 per area | New metal flashing at all roof penetrations and junctions |
Every home is different. A 1,200-square-foot ranch with a simple gable roof lands at the lower end. A two-story home with multiple valleys, a chimney, and a steep pitch lands higher. That’s why we don’t quote over the phone or by satellite imagery alone. We walk the roof, measure it, photograph it, and give you a written number that accounts for everything we can see.
Estimates from Crestview Roofing Co San Antonio are free. The price we write down is the price we honor, and if we find hidden decking damage after tear-off, we show you the photos before we change anything. Call (361) 209-8857 to schedule your inspection.
Material Options for San Antonio Roofs
San Antonio’s climate punishes cheap materials. July and August roof surface temperatures regularly exceed 160 degrees, and we get enough hail to test impact ratings every few years. We work with materials from manufacturers who engineer for exactly these conditions, including GAF, CertainTeed, and Owens Corning.
For most San Antonio homeowners, architectural shingles are the right balance of cost and durability. They’re thicker than the old three-tab style, they carry 30-year or lifetime warranties depending on the product line, and they handle hail better. Higher-end lines from CertainTeed and Owens Corning add features like wider nailing zones, improved granule adhesion, and higher wind ratings that matter during spring storm season.
Whatever you pick, we put the material choice in writing along with the price. There’s no substitution game where you approve one shingle and get another. You’ll see the shingle bundle labels in your before-and-after photos.
FAQs – Full Roof Replacement
How much does a full roof replacement cost in San Antonio?
A full roof replacement in San Antonio typically costs between $8,000 and $18,000 for a standard single-family home, or roughly $4.50 to $9.00 per square foot depending on shingle grade, roof pitch, and decking condition. The only way to know your actual cost is an on-site inspection, which we provide free with a written price before any work starts. Call (361) 209-8857 for your estimate.
Is it cheaper to repair or replace my roof?
Repair is cheaper in the short term, but if your roof is past 18 years old or has damage across more than a third of its surface, replacement is almost always the better long-term value. Patch repairs on an aging roof often become a recurring expense, while a full replacement resets the clock. During your free inspection, we’ll show you the evidence and tell you honestly which path makes financial sense.
Can you replace my roof the same day?
A full roof replacement typically takes one to three days for a standard San Antonio home depending on size, pitch, and weather. Same-day is possible only in rare cases where the roof is small and the schedule is already clear, but we do provide a written timeline before work begins and a live trackable arrival time so you know exactly when we’re on site. Call (361) 209-8857 to check current scheduling.
Do you guarantee the full roof replacement work?
Yes. Every full roof replacement from Crestview Roofing Co San Antonio is covered by our 365-Day Done Right Promise, which means any covered repair that fails within 365 days is corrected at no charge, including a free second visit if the repair fails. The materials also carry manufacturer warranties from GAF, CertainTeed, or Owens Corning depending on what you choose. Both guarantees are written and included with every job at no extra cost.
What if you find decking damage after the tear-off?
If we find rotted or damaged decking after tearing off the old shingles, we photograph it, show it to you, and get your written approval before replacing it. The per-sheet cost is listed in your original estimate, so there’s no negotiation and no surprise markup. You see the damage with your own eyes, and you approve the fix before it happens.
