The name “Organic Shingles” gives a false impression that they are green, environmentally friendly or made from organic material which couldn’t be further from the truth. It’s just clever marketing in our opinion.
While organic shingles were more flexible than the new fiberglass shingles, they didn’t pass the test of time, were susceptible to uplift during winds over 50miles/hr and held a lifespan that lasted only 7-10 years if you were lucky. These shingles are also often referred to as 3-tab shingles and are quickly being replaced by newer, better technology offered at the same price point.
Affordably priced, fiberglass shingles are thinner, lighter and less prone to uplift during winds over 50miles than old-school organic shingles. While some manufacturers offer up to 50-year warranties on manufacturer defects, one can expect these shingles to last between 10-20 years as long as they are installed correctly by a certified roofing installer.
As far as composition goes, they are generally made up of 5 layers.
