Class 4 impact resistant shingles are built to handle serious hail and debris, making them a solid choice for storm-prone areas. They don’t just look like regular asphalt shingles; they have a tougher core that absorbs hits without cracking or granule loss, so your roof stays intact longer. Installing them feels like giving your house an extra layer of armor without changing its appearance.
