Chesapeake Hydro-Wash’s Roof Cleaning Process

Chesapeake Hydro-Wash can make your roof look new again, while extending the life of your shingles.

Our roof cleaning process begins when our certified technicians arrive at your home. They will carefully inspect your roof’s condition, assess the surrounding landscape and check for any obstacles in the work area. As our proprietary blend of algaecides and surfactants are being mixed, technicians will begin setting up ladders and installing bags on gutter downspouts. These bags will capture any roof treatment solution runoff, so it can be diluted and disposed of away from the landscaping.

It’s now time to apply the first coat of our roof cleaning solution.  This coat will be applied to the heaviest of stains.  Often the entire north facing side will be treated as well as visible algae on other areas of the roof.  As the lead technician applies this first coat using fine nozzles to carefully control the spray patterns,  the ground technicians will be rinsing the adjacent landscaping of any over-spray.  Keeping plants rinsed of over-spray is very important during the cleaning process.  The first treatment will be allowed to dwell for 10-15 minutes.

After the dwell, it’s time for the second coat.  At this time, the entire roof will be treated to ensure 100% of all algae and fungus are eliminated.  Just as with the first coat, the ground technicians will continue to rinse adjacent landscaping.  As the second coat is applied, the algae and discoloration will begin to disappear.  If you happen to be watching our roof cleaning process, this is when you will really begin to notice results.  We guarantee you will be amazed by the instant same day results!

Again, our cleaning solution will be allowed to dwell for 10-15 minutes.  Now it’s time for the final coat to be applied. The entire roof will be treated again, providing a uniform finish for curb appeal and a guaranteed removal of all algae, mold, and mildew. Moss or lichen may still be noticeable at this point but rest assured that all fungus infested areas have been treated and will rinse clean with a few hard rains.

Now that the roof cleaning is completed, the crew will begin to pack up.  At this time gutters will be flushed to remove any remaining cleaning solution, and landscaping surrounding downspouts will be watered. Crew members will remove any bags that were attached to the downspouts and the captured solution will be thoroughly diluted.

All complete Roof Cleanings are backed by our  5 Year Streak Free Warranty.

Our non pressure cleaning process is fully approved by all shingles manufacturers including ARMA (Asphalt Roofing Manufacturers Association) and is recommended by all insurance companies. Roof cleaning is now considered regular home maintenance, and insurance companies are refusing to renew home owners policies on homes with dirty roofs.

We never use high pressure for any part of our roof cleaning process.  Pressure washing (low- or high-pressure) is never recommended. The use of high pressure will not only damage your roof, but will also void any existing warranty that the shingles may have. Even LOW PRESSURE is too much pressure.  Just remember…..No pressure / No Damage.
