They also report protection against new biological growth. For these reasons, Spray and Forget proves itself for the lang haul.

Cleaner Today’s Roof Cleaner QSE just needs a garden hose with a jet sprayer for application. Once you soak your roof shingles with the biodegradable cleaner, wait 25 minutes for a noticeably cleaner roof.

It works just as well and is more forgiving in application than the Roof Cleaner QSE. Also consider the company’s Roof Mold Armor to protect your freshly cleaned shingles against new mold and algae.
