Impact resistant shingles (IR shingles): Are They Worth It?
What is an impact resistant shingle? First and foremost, I want to make it clear that an impact resistant shingle is NOT HAIL PROOF. In fact, there is no such thing as a completely hail proof roof. From a straw hut to a cement tile, any roof covering can be destroyed by large hail. That being said, an IR shingle will definitely hold up better than a standard shingle. IR shingles are given the classification of 4. In order to become a class 4 shingle, it must pass the UL 2218
