Which is better - fiberglass or organic shingles?
In the end, it must be said that either fiberglass or organic shingles can be manufactured to withstand extreme performance standards. Clearly, fiber glass-based shingles have the edge in warm weather areas. Both types of shingles can be made to perform excellently in cold weather. But fiber glass shingles must be manufactured to the most stringent performance standards to perform reliably in the far north. Not all fiber glass shingles meet these standards. So, buyer beware.
