Asphalt Shingle Roof Cleaning
If you have an asphalt shingle roof with a moss & algae problem, proper maintenance will be the difference between premature replacement and getting your full life expectancy. It may come as a surprise, but it’s not uncommon to lose up to 40% due to moss & algae, or improper cleaning.
Every company will tell you something different about the best way to clean and maintain your roof. Luckily, we don’t ask you to “take our word for it”. Our roof cleaning process comes directly from ARMA, (Asphalt Roofing Manufacturers Association) and is the unanimous choice of ever professional roof cleaning association in the North America.
Here’s what the ARMA has released technical bulletins recommending.
DO: Treat your roof with a cleaning and disinfecting solution
DO NOT: Pressure wash your asphalt roof under any circumstance
Before we treat your roof, we prep your roof for maximum effectiveness. We remove the bulk of the moss with tools, leaving behind only the tough roots that cannot be removed safely. This achieves two goals, your roof will look great upon completion, and it allows us to treat the roots directly.
How does the moss and algae damage the asphalt shingles?
1. Moss & Algae feed on the filler in the asphalt shingles. As the filler is eaten away, granules will come loose, accelerating deterioration.
2. Moss Lifts Shingles. Moss grows along the edge of shingles, and will eventually start to move underneath, lifting the shingles.
3. Retained Moisture can be hard on your roof over a long period of time. It can be especially hard over the winter when freezing occurs.
