Short answer

Class 4 is the top impact rating under the UL 2218 standard, and TDI says a Class 4 roof covering receives the highest premium credit from insurers that offer one. The discount amount is set company by company, so ask your insurer for its number before you choose, and keep the installation form and product labels to claim it.

What Class 4 means

UL 2218 tests roof coverings by dropping steel balls of increasing size onto them. Products are rated Class 1 through Class 4; Class 4 withstands the largest balls without cracking. It means the shingle resists impacts better, not that it’s hail-proof.

The insurance discount

  • Each insurance company sets its own discount for each class, and Class 4 gets the highest credit.
  • Insurers decide which test standards they accept and what paperwork they need.
  • Discounts aren’t applied automatically. Ask your agent, and ask again at renewal.

Paperwork to keep

  • TDI Form PC068 (Impact-Resistant Roofing Installation), filled out by the contractor after installation. Some insurers use it; others have their own form.
  • The product label showing the lab, the UL 2218 class, the manufacturer, the brand and the year made
  • Your invoice naming the exact product

Is it worth it?

Do the math with your own numbers: get the price difference between a standard and a Class 4 shingle on your roof, then ask your insurer what the annual discount would be. Some homeowners also choose Class 4 simply for fewer storm repairs.

Common questions

How much is the Class 4 discount in Texas?

It varies by insurance company. TDI says each company sets its own discount, with the highest credit for Class 4. Ask your insurer for its figure.

Do I have to ask for the discount?

Yes. Tell your agent when the roof is installed and send the paperwork they ask for, such as TDI Form PC068 and the product label.

Are Class 4 shingles hail-proof?

No. They resist impacts better than standard shingles, but very large hail can still damage them.
