Class 4 Shingles in Colorado: Are Impact-Resistant Roofs Worth It?
What Class 4 impact-resistant shingles are, how they handle Colorado hail, and how to decide if they fit your Denver home.
November 2, 2026

Colorado properties work hard through intense sun, snow, hail, wind, and quick weather changes. A sound plan starts with understanding the condition in front of you.
What Class 4 means
Class 4 is the highest impact rating under the UL 2218 test, where steel balls are dropped onto shingle samples. A Class 4 shingle showed no cracking in that test. It is a lab rating, not a promise that a roof can never be damaged by hail.
Why Denver homeowners ask about them
The Front Range sees frequent hail. Impact-resistant shingles are built to better resist bruising and cracking, which can mean fewer storm repairs over the life of the roof.
Ask about insurance
Some Colorado insurers offer a premium discount for Class 4 roofs. Discounts vary by company and policy, so call your agent before you choose materials.
Compare the whole system
Shingles are only part of the roof. Underlayment, flashing, ventilation, and installation quality all affect how a roof performs. As an Owens Corning Preferred Contractor, we can walk you through impact-resistant options and what fits your budget.
