  1. Cleaning Roof Streaks

    Hi, Ive got the dark roof streaks from algae on the north side of the house. I would like to get rid of them without it costing me a fortune. I dont particularly want to get on the roof. My question is this: Does anyone know anything about DIY cleaning with Spray and Forget? May understanding is you can spray it on the roof by attaching the water hose to it and just leave it. The streaks will be gone in 3 to 6 months. Apparently it does not damage your shingles in any wayThe other method is to get some chloride or oxygen bleach up there one way or the other. Chloride bleach is the simplest and least costly but will it damage your shingles??? I have heard it might and I dont want that. I would try to find something to squirt the bleach up there and then rinse off with a garden hose using a ladder after a few minutes. Ive heard it works a lot quicker. Chloride bleach did a good job of getting rid of the dark stains around my stucco base -- at least after 4 days. Please help. I did not find the right solution from the internet.
