The first time a person has to think about getting a new roof for the home, it may be the first time he or she has ever given any consideration to what shingles are actually made of. Roofers in Johnston are likely to mention asphalt shingles when directing customers to images of shingle colors and patterns shown on their website. Are asphalt shingles really made of the same material that roads are?
Essentially, the answer is yes. Both contain bitumen, which accounts for the black color of asphalt roads and other areas paved with asphalt. Bitumen is a heavy, thick and sticky type of crude oil. Asphalt paving also contains sand and an aggregate, such as gravel. Asphalt shingles contain ceramic or mineral granules in addition to bitumen, and some contain fiberglass.
With improvements in recycling technology over the years, this has led to the rapidly increasing use of old deteriorated roof shingles for building roads. Those shingles can be crushed and ground up or shredded to be added to fresh hot asphalt, making road building more affordable. In addition, the granules in shingles mean that less aggregate has to be added to the road asphalt. That’s another factor in affordability, since less quarry mining needs to be done.
Roofers from a company such as Right Roofing usually can add a new layer of shingles over the existing shingles if there is only one layer in place. If the roof already has two layers, those old shingles normally must be torn off because three layers is too heavy. All the old material is removed and thrown into a dumpster that Roofers in Johnston have arranged to be delivered to the property.

Someone might wonder how roads can be built with crushed shingles from dumpsters like this, since the trash container also will have roofing nails mixed in. Recycling technology includes magnets to pull out any nails that might be left after the shingles are ground up. Now there’s no risk of those pesky sharp objects getting into pavement and causing trouble for drivers.
