How Copper Waste Has Been Introduced in Shingle Manufacturing

For the manufacturing of high quality shingles, it is necessary the usage of high quality roofing granules, like those that GreenSand Corporation produces from mining waste with high copper content that is located on the Lake Superior shoreline. Headquartered in Lake Linden, Michigan, GreenSand is using this waste as an underlayment material that facilitates leveling and adhesion of shingle granules and building fillers in many construction projects.

The resulting product, branded and commercialized as G-Sand, is reliable and provides roofs with long-lasting, dense and non-porous shingles. Roofing granules hold up very well under harsh weather conditions and have UV rays filtering capabilities, providing shingles with incomparable thaw resistance, besides being flameproof and high-winds tolerant.

On the other hand, it is usual to have granule loss in asphalt shingles when pressure washing has to be performed, increasing the roofing deterioration rate, which is only perceptible during a roofing inspection. However, the copper composition of GreenSand roofing granules hold up well not just under power washing, but heavy rains that deteriorate regular shingles quickly.

According to the American Roofing Manufacturers Association (ARMA), asphalt shingles are the most commonly used shingles in roofing systems, but these shingles must never be power-washed to avoid granule loss that contributes with fast roofing deterioration. Although, the ARMA suggests the use of chemical products for cleaning asphalt products, these products only temporarily remove algae stain that spreads faster in humid climates. Therefore, they recommend substituting asphalt and wood shingles for AR (algae resistant) shingles such as those manufactured with G-Sand shingle granules.

GreenSand roofing granules are made up of copper waste, which is not a suitable material for the development of algae, as opposite to the sand found in asphalt shingles or the natural wood deterioration when shingles of this material are installed without adequate coating. In fact, asphalt and wood shingles can be destroyed with persistent rain. Copper roofing granules are heavier and contain a fine agent that avoids the porosity observed in other shingles manufactured with delicate materials, including sand.

If you have been facing hard times with algae on your roof and have thought that all the problem is about plumbing maintenance of the drainage system but the problem is not yet resolved, think of your actual shingle manufacturing and the maintenance that you are giving to your roof. It might be worth renewing your roof and install shingles that are manufactured with copper roofing granules, which durability surpasses any other metal material and has the higher resistance to weather changes.

Opposite to what you might believe, copper shingle granules are cheap and you will not have to spend a fortune to renew your roof. Besides, the change will allow you to save a lot of money in periodical washing and maintenance.
