Galbraith says it’s typical for Envirowash to hear from other homeowners after a neighbor has his roof washed. “Our technicians literally cover every area and walk down the roof, injecting our cleaning solution and then again with our heated water application,” Galbraith says. After the stains and matter are loosened via a soft wash of heated water, technicians will follow with the rinse. “We can remove these harmful growths without causing any other damage.” Galbraith says the process begins with a proprietary cleaning solution that softens the organic material that needs to be removed. “The best way to protect your roof is just a little maintenance cleaning along the way,” Galbraith says. In winter, moss can freeze and thaw repeatedly, encouraging cracking as the roof expands and contracts. Constant moisture makes the roof heavier, which can lead to structural damage. Moss retains water, preventing the roof from drying thoroughly after rain or snow. Lichens appear crusty and will branch out along the surface, eventually turning into moss. Green stains indicate lichen, which thrives in sun. By the time the tell-tale black streaks are noticeable from the ground, the algae have been growing for three to four months. Commonly used asphalt composite shingles include crushed limestone, which is a food source for algae, leading to more rapid growth than homeowners might expect. Dark streaks on a roof indicate algae, which is caused by airborne spores that land on a surface and find a comfortable environment, usually a shady spot. “You don’t want to pay for a 20-year roof and have to replace it in 12,” says Envirowash Sales Manager Curtis Galbraith. Once the integrity of the roof is compromised, its lifespan drops dramatically. Any roof can be damaged by the presence of algae and lichens, which can break down the material’s surface or invade seams, allowing for water and insects to enter. Keeping organic growth at bay helps to preserve the integrity of whatever material the roof is made of: shingle, slate, metal, or clay. An often-overlooked element of that protection is the roof, which is the first line of defense against water and weather damage. Homeowners know that property maintenance is an important aspect of protecting their investment.
