Cleaning moss off your roof not only improves it's appearance but also increases the life span of your roof. It is important to not only remove moss but to prevent further growth. This is a guide about removing moss from a roof.
Here are questions related to Removing Moss from a Roof.
I have a three tab asphalt composition shingle roof. If I use Tide with bleach and spread it by hand all over my roof, I understand it will damage my roof. However, how long will it take a week, month, year, or one to four days to get rid of the moss?

First of all in order to grow moss the roof must be staying damp and dark so I would trim up any trees hanging over the roof, especially on the north and east sides.
Second, moss requires an acid environment to live so your best bet would be to sprinkle some agricultural lime on the roof to cut the acidic condition.
Are you by chance mistaking mold for moss?
I recently had my mossy roof sprayed with Spray and Forget and now have a roof covered with dead moss. How do I get this off? It looks worse than when it was green, even though I know this is better. I'd like to know how to get rid of it. Thanks.

I need to add a warning on killing the moss. Do not use Tide or bleach as these will shorten the life of the roof considerably.

Thrifty Fun has been around so long that many of our pages have been reset several times. Archives are older versions of the page and the feedback that was provided then.
I know that using bleach to kill, and zinc to prevent is OK. The problem I have, is that the roof I've got is huge. I bit off more than I can chew in buying this property, and it's getting quite a lot of moss growth. I know I must remove and prevent.
The problem is that I do not know what jet system to use to mix the bleach and water. Also, I can only do this from a ladder.
The zinc will have to wait.
Thanks in advance.

I have an outside shed that has one side covered with moss. Any suggestions about removing the moss without damaging the shingles?

Remove moss and algae without scrubbing: This product is amazing! You spray it anywhere you want to remove algae and moss, or to stop it from to growing. Just put it into a garden sprayer and spray it on once a year, then every time it rains, it binds with the rain and starts working. It's amazing stuff with no scrubbing required! It's called "Spray and Forget". You can buy it at Home Depot. I use it on my mobile home, my garage siding, and on our camper. I used to have quite the moss and algae problem, but no more. It also removes mildew, fungus, and lichen stains from roofs, siding, decks, brick, stucco, and other exterior surfaces with no scrubbing required.
