OK so I got motivated by Jesse so here are a couple pics. Mostly these are spray and forget yearly accounts. No scraping and the moss starts to loosen after a couple months on its own.

Those are some GREAT roof cleaning photos of BEFORE and AFTER effects of NON PRESSURE, spray and forget roof treatments!

Nice Job!

Keep on posting and providing such nice pictures about this subject of Non Pressure Moss treatment and cleaning in the Pacific Northwest.

Nice roof cleaning pictures

When using SH to kill Moss - it is helpful to lower the PH of it a bit ?

The LOWER the PH of the sh/water solution the better the killing NOT cleaning power.
Cleaning power of SH is enhanced at higher PH.

An easy way to lower the PH of your SH/Water solution is 1 gallon Vinegar to every 50 Gallons solution.

DON'T add MORE

Lower the PH TOO Much and LOOKOUT

Dangerous Chlorine gas will form and you can DIE
