Class 4 refers to the UL 2218 impact standard: the shingle resists cracking under a steel-ball impact test that approximates severe hail. In Justin, that matters twice. You get fewer storm-damaged roofs over the system’s life, and many Texas carriers discount wind/hail premiums for homes roofed with certified Class 4 products. Ask your carrier for their specific discount before you decide; we document the product certification for your policy file either way.
We install and service class 4 impact-resistant shingles across Justin and the surrounding DFW communities. Expect free written estimates, documented inspections, and honest guidance on whether this system actually fits your home and budget.
The Justin specifics
There is a Justin version of the Class 4 Impact-Resistant Shingles decision, and it is not the generic one. A large share of homes here are young enough that their original builder-grade roofs are only now meeting their first serious hail test. For those roofs, the asphalt decision is mostly a grade decision: builder three-tab versus architectural versus Class 4, each a different answer to the same hail math.
The permit runs through Justin’s building department; we handle the filing and the inspection scheduling as part of the job. When the next core drops through Denton County, Class 4 shingles take bruises where standard laminates open up. The difference shows at the adjuster meeting. Because Denton, Lewisville, and Flower Mound share our dispatch routes, examples of this exact system nearby are easy to arrange. If the roof is not a fit for this system, the inspection says so, and that answer is free too.
