Class 4 impact-rated shingles cost more up front. Whether they pay off depends on your exposure and your carrier.
Class 4 is the highest impact classification under standardized testing. It measures resistance to impact, not to wind uplift — they are separate properties.
Debris impact during storms and hail in the inland and northern parts of the state. In pure coastal wind exposure, uplift rating and installation detail matter more.
Some carriers recognize impact-rated coverings in rating. Whether yours does, and by how much, is a question for your carrier — we do not promise premium outcomes.
