A roofing company in Nassau County NY helps homeowners who are troubled by the development of unsightly dark streaks on their asphalt shingles. Three main substances cause these streaks to appear. Mold and dirt are possibilities, but the culprit usually is algae. Algae growth is more of a problem in humid areas, which characterizes the Long Island area because of the preponderance of coastline here.
Since the roof is such a focal point of any home and is often the biggest home improvement expenditure anyone will make, feeling upset about dark streaks marring the appearance is to be expected. Technicians from a Roofing Company in Nassau County NY use certain strategies depending on the specific type of problem.
Dirt
Stubborn, sticky dirt can be washed away with a garden hose and perhaps some mild soap. Low-pressure power washing may be advisable if the problem has been ignored for some time. Homeowners can complete this task as a do-it-yourself project if they are so inclined, but many people aren’t comfortable walking around on a roof or wielding cleaning equipment up there.
Mold, Algae, and Moss
Mold and algae can be removed with chemical cleaners that are safe for asphalt shingles. A pressure washer with the setting on low is useful for this purpose, too. The technicians may need to do some scrubbing with a brush to eliminate the most stubborn stains. Technicians also can get rid of any moss growth, which is important since that furry green material can reduce the longevity of the roof.
Considerations
High-pressure cleaning power should never be used on asphalt shingles as it can cause too much wear on the gritty surface. Technicians from a company such as Business Name either bring specialized equipment intended for shingle cleaning or use power washing machinery in a conservative manner.
It’s generally smarter to call professional roofers to tackle these kinds of projects since the work is hazardous for inexperienced individuals. If the roof has a low slope, it theoretically is safer than one with a steep pitch, but accidents are common when inexperienced homeowners try to clean or repair roofs.
