For roof cleaning many people, including some supposed roofing “professionals” think that using high pressure methods are the best way to clean. In fact, high pressure is the fastest way to shorten the lifespan of your roof. A low pressure roof cleaning system is the way to extend the life of your shingles.
High-pressure washers can damage the materials that make up your roof. For instance, asphalt shingles can have the granules on them that reflect away the heat from the sun are blown right off of the shingles. The high pressure can also crack the shingles or be lifted right off. Clay roof tiles can be dislodged from the roof or cracked due to the high pressure. The high pressure does blow the mold, mildew and dirt right off, but also aerosolizes the spores from mold, mildew and algae meaning that the spores settle right back on the roof and start growing again.
The mold, mildew, algae and dirt are removed by first spraying a concoction of cleaning solutions that kill the damaging plant life on the roof and soften any dirt. Once it has had a chance to work its magic, then water is used to rinse it off, but at a low pressure. It’s no higher pressure than your average garden hose.
The shingles on your roof aren’t damaged. If they are asphalt, the granules stay put. All kinds of shingles are protected from cracking and they can’t be harshly dislodged. Professional roof cleaning companies that use low pressure should also take precautions to make sure that the plants around your home are protected. Covering them and then rinsing them with adequate water to keep the solution from harming them is a usual procedure.
Don’t fall for the “only high pressure washers can get your roof clean” shtick. It’s quite untrue.
