Asphalt roofs are a cost effective roofing option, which makes them appealing to many people. However, when it comes to asphalt shingles, you get what you pay for. There are several big drawbacks to using asphalt, and one is the negative impact on the environment.
Rainwater Picking up the Lead from Your Roof
One study shows that rainwater that runs off asphalt shingle roofs contains higher amounts of lead. This means that the water that runs off your roof and into your yard and garden contains high levels of lead and is toxic.
Asphalt Shingles are Non Recyclable
Asphalt shingles aren’t recyclable. In fact, 11 million tons of asphalt shingles end up in landfills annually. One of the main reasons that asphalt shingles aren’t recyclable is the toxic chemicals that they contain. It’s also an expensive and timely process separating flashing from the nails from the shingles, etc.
Asphalt Roofs Have a Shorter Lifespan
So we know that asphalt shingles have toxic chemicals that are bad for the environment and coupled with that, they typically aren’t recycled and are piled into landfills. The next big problem I want to bring up in their lifespan. They’re still on of the more popular roofing options, so if they had the lifespan that metal roofing has, at least people would be able to get a good 70 years out of them, but they typically see deterioration after 10 years and need to be replaced at the 20 year mark. This means that people will be going through asphalt roofs at a pretty quick rate, which just adds to the toll asphalt is taking on the environment.
It’s clear that if environmentally friendliness is one of your focuses, an asphalt roof is not the ideal choice for you. Metal roofs are 100% recyclable and don’t contain chemicals that will hurt the environment.
