How Copper Fights Algae and Moss Buildup on Your Roof
Green, environmentally friendly roofs are becoming very popular throughout Vancouver. But another kind of green roof, roofing covered in algae and moss, is one of the worst kinds you can have. Fortunately, with the right kind of roofing and trim, you can very easily prevent algae from forming. Here’s a look at effects of moss and algae on your roof, and the role of copper in reducing their growth on your roof.
Algae and moss may seem totally harmless—but prolonged growth can lead to a number of serious issues that can dramatically shorten the lifespan of your roof. Moss and algae can grow between your shingles or roofing tiles, allowing moisture to penetrate the protective material and seep onto the decking.
As moss thickens, its root system will penetrate your roofing materials, which means a greater presence of water at all levels of your roofing system. Because moss and algae absorb water as it falls onto your roof, you’ll almost certainly experience water damage with prolonged moss or algae growth.
While scrubbing with oxygen bleach and specialized chemicals may eliminate your current moss or algae infestation, they won’t prevent future growth. The best way to do this is to use roofing materials made of or containing copper, which is a natural algaecide and fungicide. Many manufactures produce shingles, shakes, trim, and flashing containing copper, designed to keep algae and moss at bay. As water passes over these materials, it carries small particles of copper across your roof, killing any moss or algae that remains.
