There’s no doubt that recycling is beneficial for the environment. It reduces the need for fresh resources and limits how many items are truly wasted forever in landfills. Everyone knows that plastic bottles and aluminum cans are recyclable, but people don’t always realize that old roofing shingles can be recycled when it’s time for a new roof.
When asphalt shingles finally run their course on a roof and have to be replaced, they are usually hauled off and deposited in a landfill by Oklahoma City roofing contractors. Rising dumping fees and concern about the environment has prompted people to find better uses for these old shingles. Today, asphalt shingles are transformed into asphalt pavement for roadways or even the aggregate base and sub-base that a road requires. They can be turned into a cold patch for quick repairs of potholes and for making sidewalks. They may even be turned into brand new roofing that will get another run at protecting a house or fuel oil.
Shingles are recycled through a relatively simple process. They are ground down to a certain size with all contaminants being removed. The initial grinding will result in pieces that are between 2” and 3”. They can be ground again to create smaller pieces that are roughly ¾” in size. Further grinding can result in pieces that are no larger than ¼” in size. The contaminants that are removed in the process include metals and wood.
The biggest barriers to effectively recycling shingles are the contaminants that must be removed. Shingles that are taken from a home are typically riddled with roofing nails and may also have small splinters and pieces of wood in them from the roof deck. All Oklahoma City roofers will simply take the contaminated pieces and drop them in the dumpster. However, technology has allowed the recycling companies to easily remove these contaminants. Large magnets are used to automatically strip away the roofing nails as the asphalt shingles are ground. The ground shingles can also be placed in water tanks where the wood pieces will float to the surface to be skimmed off.
Over the years, it has become more cost efficient for Oklahoma roofers to have shingles recycled than dumped in a landfill. Here at Robbins Roofing, Inc., we care about the environment and want to do our part to help. For more information on our products and services, please visit us on Facebook.
