Roof replacement cost in San Antonio
Quick answer
Compare measured squares, tear-off layers, decking price per sheet, the full shingle system and its impact rating, ventilation and warranty — before comparing totals.
San Antonio sits in one of the most hail-prone parts of Texas, and long, hot summers bake attics and age shingles quickly. Many roofs are replaced through insurance claims, which draws out-of-town crews after every big storm. A fair quote measures the roof, prices hidden decking per sheet, says whether shingles are impact-rated, and matches the insurance adjuster's scope line by line.

What most people miss
Impact-rated shingles can pay you back
Class 4 impact-resistant shingles cost more up front, but many Texas insurers give a premium discount for them. Ask your insurer what discount applies before deciding, and make sure the roofer prices the upgrade as its own line.
How this price is built
Measured squares and pitch
One square is 100 sq ft; steep or cut-up roofs take longer to install.
Tear-off and disposal
Number of layers removed, plus dumpster or haul-away fees.
Decking replacement
Soft or damaged plywood/OSB should carry a per-sheet price.
Shingle system
Shingle line and impact class, underlayment, starter strip and ridge caps.
Ventilation
Ridge vents and soffit intake to vent hot San Antonio attics.
Flashing and drip edge
New flashing at walls, chimneys and valleys rather than reused metal.
Permit
City of San Antonio residential roofing permit, or your suburb's equivalent.
Warranty
Workmanship warranty length plus manufacturer coverage, in writing.
What makes a quote high
Post-hail urgency
Door-knockers pressing you to sign a contract before the adjuster visits.
Open-ended decking
'Wood as needed' with no per-sheet price leaves the bill open.
Bundled upgrades
Impact shingles or extra vents rolled into one price.
Deductible promises
Offers to 'cover' or waive your deductible are a red flag and generally prohibited in Texas.
Peak-season demand
Prices and wait times climb after big spring hailstorms.
Itemised versus vague
A quote you can evaluate looks different from one you can't. This is what to look for, line by line.
| Item | A quote you can judge | A quote you can't |
|---|---|---|
| Size | Measured squares and pitch stated | Full roof replacement |
| Decking | Price per sheet listed | Wood replaced as needed |
| Shingles | Brand, line and impact class named | Premium shingles |
| Ventilation | Vent type and count listed | Ventilation included |
| Warranty | Years and coverage in writing | Lifetime warranty |
Questions to ask before you approve
- How many squares did you measure, and what pitch?
- What is your price per sheet of replaced decking?
- Are these shingles Class 4 impact-rated, and what does that upgrade cost?
- Does your scope match my insurance adjuster's line by line?
- Are you local, and who handles warranty work in five years?
What to ask a San Antonio roofer
Copy these lines as they are. Politeness plus specifics gets answers.
- 1.“Please list measured squares, decking price per sheet and the full shingle system.”
- 2.“Price the impact-rated shingle upgrade as a separate line.”
- 3.“I'll compare this with my adjuster's scope and other quotes before signing.”
When a high price is legitimate
A higher-than-expected price isn't automatically a bad one. These are the situations where it's usually justified.
- Two or more layers need tearing off.
- Significant decking damage is found and documented with photos.
- You choose Class 4 impact-resistant shingles or metal.
- The roof is steep or has many valleys, dormers and penetrations.

Common questions
Will insurance pay for my San Antonio roof?
Only for covered storm damage, minus your deductible — not normal wear. Get the adjuster's scope and compare it with the roofer's quote.
Is it normal for a roofer to cover my deductible?
No. In Texas, a contractor offering to waive or absorb your deductible is a warning sign and is generally prohibited.
Do I need a permit to replace my roof?
Usually yes inside San Antonio city limits. Confirm the roofer pulls it and that the fee is in the quote.
