Class 4 Impact-Resistant Shingles & Texas Insurance Discounts Explained

The Texas Insurance Discount Angle

The Texas Department of Insurance requires insurers doing business in the state to make a premium credit available for roofing materials that pass UL 2218 testing. What TDI does not do is set the size of that discount. Per TDI’s own guidance, the amount of credit for each class of roofing material is established by the insurance company on a company by company basis, which is why one carrier’s Class 4 discount can look very different from another’s, and why any number quoted online, including in this article, should be treated as a starting point for a conversation with the homeowner’s own agent, not a guarantee. In practice, many Texas carriers advertise dwelling-coverage discounts somewhere in a broad double-digit range for a qualifying Class 4 roof, but that range swings widely enough between companies that repeating a single number as if it applies to every homeowner would be misleading. The only responsible answer to “how much will I save” is “call your agent and ask what your specific policy offers.”

What carriers typically want to see is documentation, not just a receipt that says new roof. Most insurers ask for a contractor invoice that specifically names the shingle brand, product line, and UL 2218 Class 4 rating, along with a manufacturer’s certificate confirming the product meets that standard. Texas also has a state form, TDI Form PC068, that some carriers use as part of that documentation. Comanche Roofing’s Robert spent years as an insurance adjuster before joining the team as project manager, and that background is exactly what this paperwork step benefits from: knowing what an underwriter actually needs to see, rather than sending a generic invoice and hoping it works. Homeowners in the middle of an active claim can review the Texas claim process for a fuller walkthrough of what documentation their adjuster will expect.

Cost vs. Long-Term Value

Class 4 shingles typically run somewhere in the range of 10 to 20 percent more than a comparable standard architectural shingle, largely because of the reinforced mat and impact-modified asphalt that let them pass the UL 2218 test. That upfront difference gets offset two ways over time: fewer hail-related claims over the life of the roof, and, for homeowners whose carrier offers a meaningful discount, a lower annual premium. Neither offset is guaranteed on a fixed timeline, which is why Class 4 shingles are best framed as a long-term value decision tied to how long a homeowner plans to stay in the house and how often their specific neighborhood sees significant hail, not as a purchase that pays for itself by a specific date. Two practical checks are worth doing before signing a contract: confirming the home’s roof structure can carry the added weight of a reinforced shingle, which matters more on older homes, and checking whether the neighborhood’s HOA restricts shingle colors or profiles, since Class 4 options are available across most common colors but not necessarily every style. Comanche Roofing’s shingle roofing team can walk through both checks during a free inspection.

Is It Right for Your Home?

Homeowners already dealing with frequent hail claims, planning to stay in the home for years rather than seasons, or replacing a roof that is already due for work are the clearest fit for a Class 4 upgrade. Installation quality matters just as much as the shingle itself: a Class 4 rating is earned in a lab under a specific nailing pattern and installation method, and a roof installed off that spec will not perform to the rating it was tested under, regardless of what the shingle wrapper says. Comanche Roofing’s Cody Profitt is a GAF certified roofer, and Class 4 installs follow the manufacturer’s specified nailing pattern and exposure exactly for that reason.
