If you live in Fate, Rockwall or Heath, you have probably replaced a roof because of hail, or you know a neighbor who has. That is why the question comes up on almost every replacement we quote: should I upgrade to Class 4 impact-resistant shingles?
The short answer is that for a lot of homes in this part of Texas, yes. The longer answer depends on how long you plan to stay, what your insurance company offers and what your budget looks like right now.
What “Class 4” actually means
Impact ratings come from a lab test called UL 2218. Testers drop steel balls of increasing size onto a shingle sample from set heights and check whether the shingle cracks. Class 4 is the top rating. It means the shingle survived hits from a two-inch steel ball without breaking through.
That does not make a roof hail-proof. A big enough storm can still scuff, dent or bruise a Class 4 shingle. But the bar is meaningfully higher, and in the moderate storms that roll through Rockwall County every spring, impact-rated roofs tend to come through with far less damage than standard ones.
How impact-resistant shingles are built differently
Most Class 4 shingles use a rubberized asphalt, often called SBS-modified, that flexes when hail hits instead of cracking. Some also add a reinforcing layer in the back of the shingle. The result feels heavier and more pliable in your hand than a standard architectural shingle.
That flexibility also helps in heat. Texas summers bake roofs, and shingles that stay pliable are less likely to get brittle and shed granules early. The major manufacturers we install, including Owens Corning, GAF and Malarkey, all make Class 4 lines that look just like their regular architectural shingles from the street.
The cost difference
Expect Class 4 shingles to cost more than standard architectural shingles. The gap varies by brand and by the size and pitch of the roof, so the only way to know for your home is to price both options side by side. We do that on every replacement estimate so you can see the real number instead of guessing.
The possible insurance discount
Many insurance companies in Texas offer a premium discount for homes with impact-resistant roofing. The size of the discount varies a lot from one carrier to the next, and some do not offer one at all. Before you decide, call your agent and ask two questions:
- Do you give a discount for a Class 4 roof, and how much would it be on my policy?
- What paperwork do you need from the roofer to apply it?
Usually that paperwork is a certificate or invoice showing the product name and its UL 2218 Class 4 rating. We provide it at the end of every impact-resistant install.
When the upgrade makes the most sense
Class 4 shingles tend to be a strong choice if you plan to stay in the house for five years or more, if your neighborhood has been hit by hail more than once, or if your insurer offers a real discount. They also make sense if you are tired of filing claims. Every claim goes on your history, and fewer claims can mean better rates and fewer headaches down the road.
They make less sense if you are selling soon and the buyer pool will not pay more for the upgrade, or if the budget is tight and a standard architectural shingle installed well is what fits. A properly installed standard roof is still a good roof.
Upgrading during an insurance claim
If hail damaged your roof and insurance is paying for a replacement, the claim usually covers like-for-like materials. You can still choose to upgrade to Class 4 and pay the difference yourself. For many homeowners, that is the cheapest moment to make the switch, since the tear-off and labor are already covered.
Just keep the math honest. Your deductible is yours to pay, and in Texas a contractor is not allowed to waive or absorb it. The upgrade cost is a separate line, and we will show it to you that way.
Installation still matters most
A Class 4 shingle installed badly is still a bad roof. Nailing pattern, underlayment, starter strips, flashing and ventilation all decide whether a roof lasts. Manufacturers also tie their best warranties to installation by certified contractors. Fate Roofing Group is an Owens Corning Preferred Contractor, and we install to the manufacturer spec on every job.
