Mold on roof

I have a customer with mold and black streaks on her shingle roof and she wants them removed… Is there any reason we can’t just use a pump up sprayer with SH in it and spray the mold then rinse with a hose? or do you need a roof cleaning pump?

You can do it like that. It’s a lot of pumping and spraying, but if you load up on Vitamin E…

You could but think about it, if you use 30 gallons of mix that’s a lot of trips up and down the ladder.

Buy a roof kit from Bob. The first job will pay for it.

Ok, thanks guys, ill look into the roof pump system…

Plus with a pump up, you won’t get any distance on your spray so you will need to walk the entire thing.

Those RolFlows from Home Depot could get some air.


Low pressure injector and the water broom 400 psi

Is that a pipe bomb on that sprayer lol

Hey Big J, what’s up?

That’s a wand holder duct taped on the side. The Shooter is my then fifteen year old son. Doing a little call back work.
