Yes—many Texas carriers discount metal roofs, but almost always for a certified Class 4 impact rating (UL 2218 or FM 4473), not merely because the roof is metal. In San Antonio, that discount commonly lands around $150–$500+ / year, and some Class 4 filings advertise reductions up to about 35% on the wind/hail side of the dwelling premium.
San Antonio and Bexar County sit in one of the country’s highest hail-loss corridors. Carriers offer the credit because a Class 4 roof is far less likely to generate a full replacement claim after the next storm. Stone-coated steel from major lines often pairs Class 4 impact with Class A fire ratings—two underwriting wins at once.
The discount rarely applies itself. You (or your contractor) must document the exact product and ask. Plenty of homeowners with qualifying metal roofs still pay the undiscounted rate simply because nobody filed the paperwork.
By the end of this guide, you’ll know how UL 2218 ratings work, what Texas law requires of carriers, how stone-coated steel fits, the step-by-step claim process, and what savings look like locally.

How Metal Roofs Qualify
Texas carriers key discounts to impact resistance, tested mainly under UL 2218. Steel balls of increasing size hit samples; products that survive the highest energy level earn Class 4. Many carriers also accept FM 4473. Confirm which standard your policy language lists before you buy for the discount alone.
| UL 2218 class | Typical Texas discount treatment |
|---|---|
| Class 1–2 | Usually no impact-resistant discount |
| Class 3 | Sometimes a partial credit—carrier-specific |
| Class 4 | Full qualifying discount with most Texas carriers |
Texas Insurance Code provisions require insurers writing homeowners policies here to offer a premium reduction for Class 4 impact-resistant roofing. If a carrier says “no discount exists at all” for certified Class 4, review the declarations language—or shop carriers that file the credit.
Practical rule: buy the exact model number that appears on the certification letter. Brand name alone is not enough.
Class 4 and San Antonio Hail
Class 4 uses roughly a 2-inch steel-ball impact energy—comparable to large, fast hail. Passing means no cracking, splitting, or fracturing after repeated hits on the same spot. That is why underwriters care in Bexar County, where damaging hail is a routine seasonal risk and roof claims dominate homeowners losses statewide.
The financial case is bigger than the premium line. Fewer claims also mean fewer deductibles, fewer storm-chaser delays, and less of the neighborhood scramble after a major cell.
Stone-Coated Steel and Dual Ratings
Products from lines such as DECRA, Gerard, and Metro Roof Products commonly carry Class 4 UL 2218 plus Class A fire resistance (ASTM E108). Fire credits can stack in some policies—especially near greenbelts or elevated ember-risk zones—on top of the hail discount.
Always verify the current model’s listing. Product lines update; an old brochure rating may not match what ships today. Prefer a manufacturer certification letter dated near install.
How to Claim the Discount
Document at install
Collect product name/model, the UL 2218 or FM 4473 Class 4 letter, and the permit if one was pulled. These three items are the foundation of the claim.
Call the agent
Ask specifically for the “Class 4 impact-resistant roofing discount,” and request retroactive application to the current term if the roof is already on.
Submit and confirm
Send the certification letter, the contract showing the model, and anything else the carrier lists—get written receipt. At endorsement or renewal, verify the discount is a visible line item on the declarations page.
Ask about a mid-term endorsement. Many Texas carriers pro-rate the credit instead of making you wait for renewal. Some require their own roof inspection first—schedule it promptly so the effective date does not slip.
Practical rule: if you already have Class 4 metal and never asked, call the agent this week—unclaimed credits are common.
What San Antonio Homeowners Typically Save
Local reports often land around $150–$500+ / year, depending on dwelling limit, carrier, and whether the cut applies only to wind/hail or a broader premium slice. Higher-value homes can clear $500. Over a 50-year stone-coated service life, that compounds into a real offset against the metal premium versus asphalt.
Get your carrier’s exact percentage in writing before you choose panels, then run it against your current premium.
Common Questions About Metal Roof Insurance Discounts
Do insurers discount any metal roof?
No—usually only Class 4 (UL 2218 or FM 4473). Unrated metal can still be a great roof without triggering the credit.
How much can I save in San Antonio?
Commonly $150–$500+ / year. Ask your agent for the filed percentage on your policy.
Does stone-coated qualify?
Most major stone-coated lines do when the specific model is Class 4. Verify the model number and keep the letter with your policy file.
What paperwork do carriers want?
Typically: manufacturer Class 4 letter, install contract with model number, and sometimes a contractor certificate of installation or carrier inspection.
Will Class 3 get a discount?
Sometimes a smaller one—never assume. Get it in writing for your carrier.
What if they refuse?
Ask about mid-term endorsement, confirm Texas Class 4 filing language, and compare quotes from carriers that actively market impact-resistant credits.
Next Steps for San Antonio Homeowners
Confirm Class 4 on the exact model, collect certification at install, submit it the same week, and verify the declarations page. Keep warranty and certs with the policy for the life of the roof.
