What is the difference between an organic and a fiberglass shingle?
The difference between an organic and a fiberglass shingle is the type of mat that is used in the production of the shingle. Organic shingles are composed primarily of cellulose fibers. Fiberglass shingles are composed of glass filaments of various lengths and orientation, bonded together by inert binders. Both shingles when installed properly on well made roof decks perform similarly.
