How do I prevent moss on siding?

Here is an article that might help - https://homeguides.sfgate.com/kill-moss-siding-43307.html

Hi Jim,

Have you tried using bleach after you clean the siding. Once you finish power washing your home add bleach to a spray bottle and spray the areas that are effected with bleach. ( These are the dollar store spray bottles I like).

Moss grows is very well in shaded areas. Additionally the north side of your home will get the least amount of sunlight, adding to the shadiness of the home/siding. Personally, my parents tried the bleach technique i listed above. However, the algae and moss situation didn't get drastically better until they cut down several pine trees which allowed more light in.

Use a mold/inhibiting deck cleaner and scrub off the old microscopic roots.

Then rinse with fresh bleach water.

We cleaned ours with a product called Wet it and Forget it. It really works. Most hardware stores carry it.

just use table salt and it stops mould growing
