Print VersionBookmarkEmail this page to a friend.
If you are replacing your old, worn out roof covering with new asphalt shingles, make sure they have a Class 4 rating under Underwriters Laboratories' (UL) 2218 standard. A Class 4 rating tells you a sample of the product did not crack when hit twice in the same area by a two-inch steel ball.
