I know I have asked this before but I can't find the thread. Does anyone know of someone who can cleaned our asphalt shingles? I know someone posted a name of a local, but I've misplaced it. Thanks!

Titanium Dioxide - TiO2 You can do it yourself with a garden hose (the preferred method from above). If applying from the ground, be sure to arc the water to fall over your shingles - not under or causing them to flip up. The results may take a little longer; however, the granules on your shingles will still be intact if by chance someone alternatively misuses a high pressure washer. If you need further assistance, please feel free to call. 904 483 7367
