HOW WE CLEAN YOUR ROOF
We start by applying the cleaning agents to your roof. The cleaning agents are allowed to dwell on the roof for about 20 minutes. After the cleaning agents have had a chance to do what it does best the rinse process begins after a through rinse the roof is then inspected if another applications is needed the process begins again and will continue until the entire roof is clean in some cases it may take more than 2 applications of our cleaning agents to get your roof clean. This is all part of the cleaning process. Many companies do include a rinse in the cleaning process. After applying the surfactant they wait for rain to come in to start the rinse process. Advanced Exterior Maintenance approach is different. We feel the homeowner should see instant results and should not have to wait for weeks to see a clean roof. You can see the results below.
