Class 4 impact-resistant shingles are the highest impact rating shingles carry, and in McKinney (squarely in DFW hail territory) they are the upgrade that most often pays for itself through insurance premium discounts.
A Class 4 shingle has passed the UL 2218 impact standard, a steel-ball test that approximates severe hail, without cracking. For a McKinney homeowner that pays off in two ways: fewer storm-damaged roofs over the life of the system, and the wind/hail premium discounts many Texas carriers offer on homes roofed with Class 4 products. Ask your carrier for its specific discount before you decide. Either way, we put the product documentation in your policy file.
Every estimate we write is free, and every inspection is documented with photos. We never waive a deductible, because Texas law does not allow it, and we work as your roofing contractor, not as a public adjuster.
Why McKinney Hail Makes the Class 4 Case
Within 8 miles of McKinney, hail an inch or larger has fallen on 39 separate days since 2006, and 18 of those days brought golf-ball-size stones or bigger. The largest stone on record measured 4.5 inches on March 24, 2019. Standard laminates tend to open up under that kind of load, while a Class 4 shingle is built to take the bruise and keep shedding water, and the difference shows when the adjuster walks the roof.
Housing here is young. The median home in this Collin County city was built in 2007, and 40 percent went up in 2010 or later, so a large share of roofs still carry the builder’s original shingle. The first replacement is the natural moment to step up to an impact rating instead of repeating the builder’s choice. The same crews handle Class 4 installs in Allen and Fairview.

Common questions about class 4 impact-resistant shingles in McKinney
Do Class 4 shingles make my roof hail-proof in McKinney?
No. Class 4 is the highest impact rating, not immunity. Large hail can damage any roof. The rating means significantly better resistance to the hail sizes DFW sees most often.
How much do I save on insurance with Class 4 in McKinney?
It varies by carrier and policy. Texas insurers commonly discount the wind/hail portion of premiums for certified Class 4 roofs. Your agent can quote the exact discount; bring the product certification we provide.
Is upgrading from builder-grade shingles worth it in McKinney?
Usually at the first replacement or claim: Class 4 impact-rated systems earn many Texas carriers' premium discounts, and newer communities' HOA standards generally approve them easily. The math works hardest on homes facing decades of DFW hail.
How often does hail hit McKinney?
