Recycling /reusing Roofing Material

Pulling down a roof generates substantial waste that does not need to be dumped into landfills. The materials use for roofing can be recycled or reused depending on their properties and qualities. Various roofing materials can be recycled and reused as follows:
Asphalt shingles

Experts estimate that asphalt composition shingles claim nearly 90% of the roofing market. According to the Environmental Protection Agency, between 7 and 10 million tons of asphalt roofing end up in US landfills each year! Metro Vancouver has initiated a pilot program to investigate and test new opportunities for asphalt shingle recycling into paving mixes. Currently, no facilities exist for recycling asphalt saturated roofing felt. Because asphalt roofing material is not recyclable or reusable, it is the least environmentally friendly option.
Shingle recycling is economically viable, convenient where available and saves valuable resources from being sent to a landfill. Recycled asphalt shingles are most commonly used in pavement, which offsets the need for new asphalt and aggregate, and additional applications are being explored. Asphalt shingle recycling can create jobs for recycling locations and reduce costs for paving.

If old metal roofing is still in good condition, building materials salvage companies can sell it for reuseeven small amounts come in handy for garden sheds and outbuilding projects. Even small amounts come in handy for garden sheds and outbuilding projects. Metal flashing can also be recycled and reused if in good condition. Dismantling and removal are the keys to successful reuse.

Tiles and Slate
Other high-end roofing products like terra cotta, Spanish tile, and slate are candidates for reuse, as well. In fact, theres an active national market for buying and selling vintage tile and slate roofs. Concrete and clay tiles are mineral-based, nontoxic, and can be reused in manufacturing. Tiles and slates can be recycled and used as aggregate in other concrete products and cement production. This, in turn, reduces demand for quarrying of virgin material, reduces the amount of waste going to landfill in local areas near our sites and reduces energy consumption.

Wood sheathing
As mentioned earlier, if your roofs sheathing is in good condition, consider reusing it. Preventing waste in the first place is better, and cheaper than recycling. If your old tongue-and-groove sheathing is going to be removed, investigate whether it could be sold. Often this material can be milled into beautiful interior trim or even flooring by companies that deal in the remodeling of timber waste.
