How Have Shingles Improved in the Last 50 Years?

shinglesShingles look much the same as they did 50 years ago, but the ones installed by a roofing company today will likely have some important differences that make them safer and longer-lasting than they used to be. One of these differences is in the backing, or mat, the visible aspect is attached to. Other differences include how many tabs they have, how much asphalt they include, and cosmetic differences like color selection.

The old shingles roofers used were made mostly of organic material and had a felt mat for a backing. This natural material isn’t a good thing when it comes to roofing because it can decay if it gets wet, and it can also burn more easily than a non-organic substance. For this reason, about 90 percent of the shingles installed today have a fiberglass mat instead of an organic one. While there were a few issues with fiberglass shingles when they were first developed, the kinks have now been worked out, and they are currently the superior option.

One of the things that makes fiberglass-backed shingles superior is that this material does not rot so you can leave it in storage in Winnipeg for as long as you want. It’s also far more fireproof than felt, and shingles made with this material typically earn a Class A fire rating. In terms of fire resistance, Class A means they can resist a severe fire. While this won’t keep the rest of the house from burning, it will ensure the shingles don’t become part of the problem.

The number of tabs on shingles has also changed in some cases. Typical shingles have three tabs. Once installed, this makes the roof look as though it is made with three times the number of shingles than it actually is. By varying the number of tabs, different visual effects can be produced.
Visible improvements in shingles generally take the form of expanded color palettes that allow homeowners to choose options that provide designer looks. Another type of improvement is the development of extra-reflective shingle colors. Such reflectiveness allows the roof to reflect the sun’s light and heat back into the sky, and this is a prized feature in hot areas like the Southern United States.

These are just some of the improvements that have been made in shingle technology over the last several decades. Ask your roofing company about all the ways new shingles can benefit your home.
