Roofing in San Antonio

San Antonio sits in a hail-prone corridor, gets long stretches of intense heat and UV, and has no state licensing system for roofers. That combination puts an unusual amount of responsibility on the homeowner.

No Licence: You Are the Filter

Texas does not license roofing contractors. After every significant hail event, crews arrive from out of state, canvass neighbourhoods door to door, work a season, and leave. A twenty-year workmanship warranty from a company that no longer exists is worth nothing.

Verify, every time:

• A permanent local business address. Look it up. Not a PO box, not a phone number.
• General liability insurance, with the certificate sent to you directly by the insurance agency, not forwarded by the contractor.
• Workers' compensation. Texas does not require it. Roofing is the most dangerous residential trade, and if an uninsured worker is hurt on your roof the claim can land on your homeowner's policy. Ask specifically.
• Texas sales tax permit and a verifiable business history in Bexar County.
• References from two years ago, not two months. Anyone can produce a satisfied customer from last week.

Two specific red flags:

• An offer to waive or absorb your deductible. This is insurance fraud in Texas.
• Pressure to sign an "authorisation to inspect" that is actually a contract contingent on insurance approval. Read what you sign. These documents often lock you to the contractor regardless of the settlement.

Hail

Bexar County is squarely in a hail corridor, and damaging events recur.

Assessing Damage

Hail damage on asphalt shingles looks like dark bruises where granules have been knocked away and the mat is exposed. It is often not visible from the ground, and it does not necessarily leak immediately — it shortens the roof's life by exposing the asphalt to UV.

Check soft metals first: gutters, downspouts, vents, the air conditioning condenser fins, and any metal flashing. Dents there confirm hail of a damaging size hit the property, and they are visible from the ground.

Insurance Realities

• Wind and hail deductibles are often a percentage of the dwelling coverage rather than a flat amount. On a $400,000 dwelling a 2% deductible is $8,000, which changes whether a claim is worth filing.
• Actual cash value roof endorsements are increasingly common in Texas. Under ACV, depreciation is deducted from the settlement and you cover the difference. Check whether your policy has one, because it can mean a very large out-of-pocket share on an older roof.
• File promptly. Policies have notice requirements and Texas has a statutory framework for claim timelines.

Impact-Resistant Shingles

UL 2218 Class 4 shingles are tested by dropping steel balls on them. They cost 15-25% more and most Texas carriers offer a discount of roughly 10-30% on the wind and hail premium.

In San Antonio the discount usually repays the upcharge well within the roof's life. Ask your carrier for their specific figure before choosing, since it varies significantly between companies.

Heat and UV

San Antonio's heat load shortens asphalt shingle life. The volatile oils that keep asphalt flexible are driven out by heat and UV, and shingles rated for 25-30 years commonly deliver 18-22 here.

Mitigations:

• Ventilation. Balanced soffit intake and ridge exhaust keeps the deck cooler and extends shingle life. The most common defect in San Antonio homes is adequate ridge venting with blocked or painted-over soffit vents, which produces no airflow at all.
• Radiant barrier on the underside of the deck, $1,500-$4,000, reduces attic temperature by 20-30°F.
• Lighter shingle colours run measurably cooler.
• Algae-resistant shingles with copper granules prevent the black streaking that humidity produces on north-facing slopes.

Installation Details That Determine Wind Performance

A shingle's wind rating assumes correct installation. The details that matter:

• Six nails per shingle, in the manufacturer's specified nailing zone. This is the single most common defect and it is why roofs fail below their rated wind speed.
• Ring-shank nails on deck sheathing for uplift resistance.
• Properly fastened starter strip and drip edge. Edges are where wind gets under a roof.
• Sealed deck seams or a fully adhered underlayment as a secondary water barrier — inexpensive during a replacement, impossible to add later.

Put the nailing specification in the contract and check it during installation. It takes thirty seconds to lift a shingle and count.

Tips for San Antonio Homeowners

1. Check gutters and condenser fins for dents to confirm hail size before filing.
2. Know whether your policy is ACV or replacement cost on the roof, and what the wind and hail deductible actually is.
3. Never accept a deductible waiver. It is fraud and it flags a contractor to avoid.
4. Specify six nails per shingle in writing.
5. Verify insurance certificates with the insurer directly, not with the contractor.
