As many of our clients know and have experienced, we guarantee our services. Part of our roof cleaning process is our follow up process. During this process we come out and inspect the roof for up to 3 months and retreat it if necessary at that time unless more time is needed for heavy growth. Doing this ensures 100% removal and that it’s done safely. Imagine pulling weeds out of the ground where the roots tear up the area. We avoid this by allowing them to die and detach from your roof. If we didn’t do this and promised results within the same day, it could damage your roof which none of us wants to let happen. So taking a safe, slow and efficient process we can allow these microorganisms to die and detach themselves from your roof, leaving your roof unaffected by the removal process and looking great again for years to come.
