Anyone have any good way to clean asphalt shingles? Of course, won't use power washer. What is best solution to use and wash off - tsp, bleach, anything else?>>>

RABOIN

A 50-50 solution of bleach and water works as good as anything else to kill the algae. Be careful!

What is with this forum. It is scewing with my computer something crazy. I took about 10 minutes to get this far.>>>

REDSHIRT ROOFING

ABC sells a cleaner I think it's called Shingle Shield. It works real well but you should also install zinc strip afterward to help prevent regrowth of algae.>>>
