Is it a dream to have an affordable, long-lasting roofing material that is environmentally-friendly at the same time? With metal roofs, it’s never a dream — it’s an everyday reality. Metal roof recycling is an excellent practice of many metal roofing manufacturers, professional and greatly dependable London ON roofing contractors, and homeowners. The real winners are homeowners because they won’t need to spend so much for a durable roof that lasts long and is sustainable.

Apart from metal roof recycling, the roofing material has exceptional long-term benefits that save utility costs. It can save energy by improving internal insulation. How does it achieve such? Earth 911 has a great explanation below.

Why Do Metal Roofs Save Energy?

As the demand for energy-saving building materials increases, metal roofs are installed more often. A study funded by the U.S. Department of Energy and conducted by the Oak Ridge National Laboratory shows why metal roofs promote energy conservation in the home. The answer has to do partially with how the roof is installed.

In the study, the metal roofing was attached with a batten/counter-batten system that allows airflow underneath. Researches found a 45 percent decrease in the flow of heat with the metal roof, mostly attributable to the ventilation above the sheathing. Researchers also found up to 25 percent reduction in cooling costs.

When the roof is nailed directly to the roof deck, there is no air space below. This causes greater heat loss from the attic in the winter. Having an air gap acts almost like insulation, preventing heat transfer out of the home. Likewise, in the summer, an air gap prevents the heat of the sun from warming up the attic and the rest of the home.

Metal roofs can have solar reflective coatings applied, which reflect the sun’s radiation and are helpful in warmer climates. In contrast, asphalt shingles store and retain more heat in the summer. (Continued)

Once your roof reaches the end of its lifespan, you’ll need to call professionals to completely tear it off and replace your new roofing material in the best and most accurate way possible. However, if you own or can borrow some roofing equipment, you can perform the tear off and recycling on your own.

Pisci Cultura Ara Cangua has a great guide on how to remove your old metal roof and replace it with a new one. The content is quite detailed, but make sure you have prior roofing experience before attempting to perform this on your own.

How Do You Recycle An Old Metal Roof?

One of the benefits of metal roofs is that they are recyclable. The companies who install metal roofs cite this fact all the time to compel you to put in a metal roof, but what really happens when the roof is at the end of its lifespan? How easy is it to recycle? To answer your questions, here are some tips and a look at the process.

1. Use Snippers to Remove Nails

Most metal roofs consist of large sheets of metal held in place with nails. You can remove the nails by pulling them out with the claw side of a hammer, but that can rip holes in the metal. That can lead to sharp protruding edges that may cut you while you’re dealing with the metal.

To eliminate that risk, consider using a pair of snippers. A simple hand tool works perfectly in this situation. Just position the shippers under the head of the nail and cut. When all the nail heads have been cut off, you should be able to lift up the metal sheet. If you like, you can snip off the remaining portion of the nail that is sticking out of the back of the panel.

2. Wear Safety Gear

Sometimes, the broken nails will just fall out of the metal panels. Make sure to wear shoes to protect yourself. Also wear work gloves rated for working with the same gauge of metal as your roofing panels. (Continue Reading)

Are there alternative materials to compare with metal roof recycling? Metal roof’s durability is unparalleled (because even clay and slate tile are highly durable but brittle), but other materials possess the same level of recyclability as it does. In fact, some of these recycled roofing materials are quite interesting.

Abbey Roofing has a great list of unconventional materials that we highly recommend not to use as your roofs despite their recyclability. However, they do make for an interesting read!

Unlikely Materials Alternative to Metal Roof Recycling

Milk Jugs

Using recycled milk jugs is a great alternative to wood or metal materials. The plastic is resistant to moisture and chemicals so doesn’t weather damage or provide a breeding ground for bacteria in the way that a wooden option would. The plastic is also malleable so can be moulded into any shape for your roof tiles.


Recycled tyres are the best option if you’re looking for something that looks most like a normal roof. The tyre wall is removed and the tread is cut into large pieces which is buffed out and covered in slate dust or sawdust. The pieces are moulded into shape and a plastic tab is added to each individual shingle to make nailing the pieces down easier. The steel belting from the tyre is left in tact so the finished product benefits from being stronger and more long-lasting than a typical asphalt roof.


In 1922, Elis Stenman built a house out of newspapers rolled up and varnished, to highlight how much wastage our society produces. In 2003, NewspaperWood was produced. This idea comes from Norway, where over 1 million tonnes of paper and cardboard are recycled every year. The process sees newspapers and solvent-free glue rolled up to create a log, which is then cut into planks as a real wooden log would be. The produce is completely waterproof and flame-retardant and can be used to build anything you would use wood for. (Continued)
