The precursor to the fiberglass shingle is the felt mat shingle. This is worth noting because some fiberglass shingle designs still use a felt layer. These are not pure fiberglass shingles, and the mixed materials do not provide any benefit.They are slightly lighter in weight but considerably less durable.he roof can be one of the most expensive items in your home and that is why itâs imperative to do your research and pick the best roofing material for your home and area. Fiberglass shingles are extremely durable and oftentimes, come with a lifetime warranty.
At any rate it is up to you to decide what type of roof you would like to put on your home. Every shingle manufacturer in the USA is an asphalt composition roofing shingle. All Asphalt fiberglass composition shingles come with a 20 year to lifetime warranty and anything in between.ack in 1989 when I installed my first asphalt shingle there was many changes in the roofing manufacture sector. The end result was down-sizing the weight to accommodate a more flexible shingle. The old shingles in the USA were known as Asphalt roofing shingles or a standard strip 3-tab shingles.
