Roof Washing
You might have noticed staining or discoloration on your roof and wondered what was causing it. The simple answer is harmful bacteria. The shingles on your roof most likely have a limestone component to them and this is what the bacteria feeds on. The final result if left untreated – your roof will decompose faster.
The decomposition of your roof is caused by the erosion of the shingles done by the infectious bacteria and it can lead to weakening, discoloration, hardening and eventual cracking preceding the shorter lifespan. The more prevalent the streaks or discoloration that you notice, the worse the issue is.
American Window Cleaning offers the only recommended process to clean your roof according to both ARMA (Asphalt Roofing Manufacturers Association) and GAF (North America’s Largest Roofing Manufacturer). This process utilizes a low-pressure application of a proprietary, 100% biodegradable cleaning solution. The cleaning can be applied to all types of roofs including Asphalt Shingles, Slate, Tile, Wood Shake, Metal and Rubber Membranes.
Since our system uses a low-pressure wash method that attacks the root of the problem, we offer a 5 year Spot Free Limited Warranty when you have a complete roof cleaning performed. The warranty is also transferable if you end up selling your home within that 5 year period.
Other issues that can be related to the growth of bacteria and algae on your roof include:
Increased Utility Costs
Loss of Insurance Coverage
Decreased Curb Appeal
It is important to remember that you should never pressure wash your roof. Contact American Window Cleaning to give your roof a professional grade cleaning.
