ORGANIC VS. FIBERGLASS SHINGLES
Organic is the current word used to describe traditional asphalt shingles, which differentiates them from, an up-and-coming alternative, called fiberglass shingles. There’s some confusion about organic shingles. Some people think they’re green, environmentally friendly or made from organic material but that is not the case. When it comes to shingles, organic means non-synthetic.
With traditional shingles, the manufacturers, would use recycled paper to create the base of the shingle, new fiberglass shingles use a fiberglass base. The two types of shingles look the same on your roof and they are both made by a similar production process: base, tar, saturated then coloured granules embedded into the asphalt. Both organic and fiberglass shingles are flexible and both are applied by installers the same way. The difference has to do with what the tar and gravel mixture is bonded to.
Since 2010 shingle manufacturers in North America have moved away from traditional organic base. Manufacturers have made this move in order to avoid expensive warranty claims.
Organic shingles are built on a substrate of heavy felt, while fiberglass shingles have a foundation of non-woven glass fibers. This difference doesn’t sound like much, but it actually leads to substantially different performance, especially in particular situations.
The main advantage of fiberglass shingles is their resistance to heat. They’re much less likely to curl up than organic shingles, even when used on hot, poorly ventilated roof structures. Fiberglass shingles are also less susceptible to catching fire or melting from the heat of a fire below.
