Davis Roofing: Article About Asphalt Shingle Recycling Needs
Asphalt shingles are the most common material used for roofing in the United States. It is estimated that old shingles and new installation scrap account for seven to 10 million tons of the waste that is generated during new construction and reroofing projects each year. However, it's starting to be more and more common for those asphalt shingles to be recycled instead of sent to a landfill. Shingle recycling is offered in most major markets across the country, including areas covered by Davis roofing contractors.
Sometimes during a roof tear off, there are two layers of asphalt shingles that need to be taken off. It is often the case that new shingles are overlaid over old ones during a reroofing project, so roofers will find a 40 year old layer of shingles underneath the 20 year old layer. Considering that the average roof weighs between three to four tons, when a homeowner recycles their asphalt shingles, there is a lot of material that is being diverted from landfills. In addition to saving money by recycling, homeowners can feel good about making a positive contribution to the environment.
Not just old shingles are being recycled. After asphalt shingles are made, tabs are usually cut out to properly shape the shingles for assembly. These tabs can be recycled since they contain fresh asphalt.

Manufacturers can also recycle shingles that were defective or otherwise didn't meet their quality standards.
The cost of recycling asphalt shingles is usually less expensive than the cost of sending it to a landfill. The cost can be decreased further if the materials are separated properly. In some areas, recycling is free. The recycling facility will prepare the asphalt shingles for use in new products by grinding the shingles down. Metals, such as nails, will be removed with the use of a powerful magnet. Wood that may have come off the roof during the reroofing project will be removed by hand, or in some cases with the use of a water flotation unit.
The number one use for recycled asphalt roofing shingles is in the making of new roads. It's also used in cold patch repair for potholes, for paving driveways and parking lots, and as an additive to new asphalt shingles. Integrating recycled asphalt shingles into pavement can actually make for a better performing road surface because the asphalt that is used to make shingles is harder than pavement asphalt. Recycling asphalt shingles can be a winning proposition for the homeowner, the end user and the environment.
