If your home has a roof, you may be wondering: “How are old roof shingles recycled?” Thankfully, many of these materials can be recycled. They are often overlaid with new shingles and recycled into hot asphalt, which is then used for paving projects. In some cases, they are even used to make new shingles.
Roofing shingles can be recycled
Roofing shingles can be recycled into new roofs and can reduce the environmental impact of the construction process. In addition, you can reuse the roofing material for other purposes. Asphalt shingles comprise 75% of the roofing materials used in the United States. However, they can take up to 300 years to fully decompose in a landfill.
The GAF RoofCycle(tm) Process diverts shingle waste from landfills and repurposes the shingle waste in the production of new shingles. Roofing shingles made from recycled material contain as much as 7% recycled content. However, these products are currently only available in limited quantities.

Roofing shingles are often overlaid with new shingles
While most building codes allow homeowners to put two layers of asphalt shingles on a house, there are several reasons to replace old shingles with new ones. Overlaying the shingles with new ones is cheaper and requires less labor than tearing the old shingles off. However, this method means that you won’t be able to assess whether there are any leaks, water damage, or deterioration to the sheathing. Overlapping is also useful if the roof has been damaged by trees or wind storms.
New shingles are shaped and cut into tabs to fit a specific roof. The tabs are also discarded if they do not meet quality standards. Most shingles come with a fiberglass mat. They are then ground to a specified size and inspected for contaminants. During the winter months, it is easier to grind the shingles to size, because the heat may cause them to stick together.
Roofing shingles are repurposed into hot asphalt
Asphalt shingles are recycled for use in a variety of applications. The most common one is in road construction. Asphalt shingles are composed of a mixture of asphalt cement, fiberglass or organic fibers, and mineral fillers. During the production process, the asphalt is stabilized with mineral stabilizers to make it more durable and weather resistant.
Asphalt shingles have many different shapes. They range from jet shingles to signature cut shingles to Art -Loc shingles. There are also architectural shingles that are laminated several times and add more water resistance. You can also find standard three-tab shingles that are used for the ridge line. Some styles of asphalt shingles interlock with adjacent shingles to provide a stronger, wind-resistant surface.
Roofing shingles are used for paving projects
Roofing shingles can be a great substitute for asphalt in paving projects. The shingles are recycled into tabs and can be used as hot mix asphalt substitutes or as ingredients in cold mix asphalt patching materials. Recycling these tabs is a great way to keep asphalt out of landfills. It also saves paving contractors money.
Roofing shingles are recycled into asphalt for paving projects in several states. This helps divert asphalt waste from landfills and reduces road paving’s environmental impact. By using recycled asphalt shingles, a typical paving project will save an estimated 27,000 pounds of carbon dioxide. Asphalt shingles can be recycled as much as 5% by weight.
Roofing shingles are made of cedar
Cedar shingles are made from the wood of the cedar tree. The logs are cut into wedges and the bark and knots are removed. The logs are then towed to the edge of a river and are sorted and cut. The resulting material is then turned into roofing shingles. The process used to make the shingles is a time-honored method that has been used for many years. Cedar shingles are one of the strongest roofing materials that are available. They have an average life span of 30 to 40 years. They may last longer if they are maintained properly. Cedar shingles can enhance the value of your home. These shingles typically last for 30 years, but they can last longer if properly maintained and in an area of high humidity.
