Dark stains on shingles?
 

Does anyone have a solution for the formation of I believe mildew
or mold that can discolor shingles? I believe there is a chemical that
can almost makes these stains disappear upon contact. I once saw a
demonstration of mildew disappearing from a sidewalk with a chemical
but I have no idea of what the chemical was.

a solution for the formation

zinc or copper strips. May have to go to a real building supply place
for them.

of I believe mildew

Black Algae probably

a chemical that can almost makes these stains disappear upon contact.

Household bleach will do in most of that stuff. That was on a sidewalk.
Bleach ain't gonna hurt that.

If you get any ideas, DON'T PRESSURE WASH A ROOF. The only people that
will recommend that are people that do it for money and people that have
done it.

While I agree with what they say is the problem, they are trying to rope
you in to keep buying the stuff.

"A standard practice should be to clean your roof and then apply a
preventative such as Spray & ForgetTM every 18-24 months"

"Adding a roof algae/moss prevention program to your ..."

Zinc/copper strips will stop it as long as there is zinc/copper on the
strips.

Anytime reroofing is done, Algae Resistant shingles should be used. Might
even be standard across mfgrs by now.

And BTW, the best leak prevention program is to stay the hell off the
roof.

I would never consider cleaning the roof if it involved any physical
pressure on the grains in the shingles. The above product does not
require scrubbing or rinsing. It only requires a time period for the
results to show.
