Tomball · Class 4 insurance discount

Class 4 impact-rated roofs in Tomball — pay less to insure your home.

Most Tomball carriers credit 10–30% off the wind/hail portion of your premium for the life of a UL 2218 Class 4 roof. We install it and provide the certificate your carrier needs.

Tomball sits in one of the most active hail corridors in Greater Houston. Insurance carriers know it — and they reward homeowners who install impact-rated shingles with a permanent premium discount on the wind/hail portion of the policy. P91 Roofing installs Class 4 shingles from GAF, Owens Corning, CertainTeed, Atlas, and Malarkey, and we send your carrier the exact documentation they need to apply the credit on your next renewal.

How the discount actually works

UL 2218 is the impact-resistance test: a 2-inch steel ball dropped from 20 feet onto a shingle. Class 4 shingles must show no cracks, splits, or fractures after the test. Texas carriers — State Farm, Allstate, USAA, Farmers, Texas Farm Bureau, Liberty Mutual — credit the wind/hail premium when they receive the manufacturer certificate showing your shingle passed the Class 4 test. The credit applies for the life of the roof, not just one year.

What the upgrade costs vs. what you save

Class 4 shingles run $400–$900 more per square than standard architectural — roughly $1,200–$2,700 added on a typical Tomball roof. Annual premium savings are usually $300–$900. Most owners recover the upgrade cost in 3–5 years and keep saving for the remaining 15–20 years of the roof's life. That's before counting fewer post-hail claims (and a lower deductible exposure).

What we send your insurance carrier

At project handover you receive a one-page documentation packet: the manufacturer's Class 4 impact certificate (specific to the shingle line on your roof), the itemized installation invoice, and a date-stamped photo of the completed roof. Forward all three to your agent — every Texas carrier we've worked with applies the credit on the next renewal cycle.

FAQ

How much does the Class 4 discount actually save?+

Most Tomball-area carriers (State Farm, Allstate, USAA, Farmers, Texas Farm Bureau) credit 10–30% off the wind/hail portion of your premium for the life of the roof. On a typical Tomball home that's $300–$900 per year.

Which Class 4 shingles do you install?+

GAF Timberline AS II, Owens Corning Duration FLEX, CertainTeed NorthGate ClimateFlex, Atlas StormMaster Shake, and Malarkey Vista AR. Each carries a UL 2218 Class 4 impact rating.

Does the discount apply if I just had a regular roof installed?+

No — the carrier requires a manufacturer certificate showing UL 2218 Class 4 rating for the specific shingle on your roof. Standard architectural shingles are Class 3 or unrated.

What documentation do I send my insurance carrier?+

We provide three things: the manufacturer Class 4 certificate, the installation invoice, and a roof photo with date stamp. That's everything every Texas carrier we've worked with requires to apply the credit.

Does the upgrade pay for itself?+

Class 4 shingles cost $400–$900 more per square (100 sq ft) than standard architectural. On a 30-square Tomball roof that's $1,200–$2,700 added. Most owners recover that in 3–5 years through premium savings, before factoring in better hail performance.
