ROOF STAINS

Want to get those ugly roof stains from that algae washed off. Roof is just too steep for the hubby to do it. I know you're not supposed to use high pressure. Has anyone had their roof cleaned and if so who did it??

 

Use the high pressure and spray over so the chemicals "rain" onto the stains instead of being direct spray.

 

What chemicals do you use?

 

I've read to use bleach but not chlorine bleach because it can damage the shingles.

 

I cant remember the name of it, but you can go to the Home Depot and get it.
