When it comes to replacing your roof, the choices can feel overwhelming. One term you might hear from roofing contractors is Class 4 shingle. But what does that actually mean — and is it worth paying extra for here in Southeast Michigan? Let’s break it down.
What Does “Class 4” Mean?
Shingles are rated for impact resistance using a system created by Underwriters Laboratories (UL 2218). The ratings range from Class 1 (lowest impact resistance) to Class 4 (highest impact resistance).
A Class 4 shingle is designed to withstand severe impact — like hail or flying debris — without cracking. In testing, they drop a steel ball from 20 feet onto the shingle multiple times, and a Class 4 shingle must survive without showing signs of damage.
Why Class 4 Shingles Matter in Southeast Michigan
Here in Southeast Michigan, we may not get giant hailstones like the Midwest plains, but we do get:
-
Heavy windstorms
-
Flying branches and debris
-
Lake-effect snow and ice
-
Harsh freeze-thaw cycles
All of these can wear down a roof quickly. Class 4 shingles provide an extra layer of protection, meaning your roof will last longer and need fewer repairs over time.
Brands We Recommend — CertainTeed & Malarkey
At Level Up Improvements, we install CertainTeed and Malarkey Class 4 shingles. Both brands are known for quality, durability, and great warranties.
-
CertainTeed NorthGate® SBS: Flexible in cold weather, excellent for Michigan winters, and top-rated for impact resistance.
-
Malarkey Vista and Legacy®: Made with rubberized asphalt for extra durability and 3M smog-reducing granules to help the environment.
Is the Investment Worth It?
In many cases — yes. While Class 4 shingles do cost more upfront than standard shingles, the benefits often outweigh the extra expense:
- Longer lifespan – Less chance of damage means you may not need a replacement as soon. The more pliable asphalt hold the granules much more securely, meaning less fall off over time.
- Lower repair bills – Better protection from storms reduces emergency fixes.
- Possible insurance discounts – Some insurance companies offer savings for Class 4 roofs.
- Better resale value – Homebuyers love knowing the roof is top qualit
For homeowners in Oakland County, Wayne County, and the rest of Southeast Michigan, the upgrade can be a smart choice — especially if you want peace of mind during our unpredictable Michigan weather.
