Class 4 Impact-Resistant Shingles: Why Every Tulsa Homeowner Should Consider Them

If you are replacing your roof in Tulsa and you are not considering Class 4 impact-resistant shingles, you may be making an expensive mistake. Here is why.

What Are Class 4 Shingles?

Shingles are rated for impact resistance on a Class 1–4 scale, with Class 4 being the highest. To earn Class 4 designation, a shingle must survive being struck by a 2-inch steel ball dropped from 20 feet — simulating large hail. Standard architectural shingles are typically Class 1 or 2.

The Oklahoma Insurance Discount

This is the most compelling reason for Tulsa homeowners: most Oklahoma insurers offer a premium discount for homes with Class 4 roofs. The discount typically ranges from 15–30% on your wind/hail premium. Over 10–15 years, this discount can equal or exceed the additional cost of upgrading to Class 4 shingles at replacement time.

Before you replace your roof, call your insurance agent and ask specifically: "What discount do you offer for Class 4 impact-resistant shingles?" Get the number in writing, then compare it to the upgrade cost when reviewing estimates.

How They Perform in Tulsa Hail

Tulsa regularly sees hail events with stones 1–2 inches in diameter. Standard shingles show clear damage — bruising, granule loss, cracking — at these sizes. Class 4 shingles resist this damage significantly better. While no shingle is indestructible, Class 4 products routinely come through hail events that would require full replacement on a standard roof.
