For those wanting a flatter looking shingle with a little flair this offering may fit the bill. It's a single layer asphalt shingle made to look like slate shingled from the old world. Cuts and installs relatively straight-forward. It's heavy at 240lbs a square but not as heavy as some other shingled in this category. Offered in an Impact Resistant line "IR" as well - we suggest if you are spending the money to go ahead and go for that variety - be sure to check out the other slate look shingles from GAF and Owens Corning as well.
