Killing and removing roof moss isn't really all that difficult. It is however time consuming. It will also require you to get up on your roof. What follows on this page are the steps you'll need to take in order to kill and remove the moss that's on your roof.
I am fortunate enough to have a friend who owns a roofing business. Although his business doesn't deal with roof moss removal, he was able to tell me what had to be done to get rid of it. He explained that in order to completely eliminate the roof moss, it would first have to be killed and then it would have to be removed. Failure to remove the moss after killing it would mean that you'd just have a bunch of dead moss on your roof which, if you plan on preventing re-growth, will hinder the desired effect of the zinc strips you're going to install.
OK Let's Get Started
First, in order to kill the moss, you’ll need:
- A good, safe, ladder
- A rubber garden hose long enough to get up on the roof
- A good roof moss killer
There are many products on the market that claim to kill moss. The moss killer that was recommended to me was a product called Moss Out. As with most of the other products that kill roof moss, the container simply attaches to the end of a garden hose and automatically mixes with the water as you spray. Once on the roof, simply spray the entire roof with the roof moss killer and water mixture, and leave it alone for a few days. The product claims that you could start to see results in as little a few hours. I did not experience that, but within a few days, all the moss had turned brown and died. The whole process from set-up to clean-up takes less then a day to complete.
That Was Easy!…What's Next?
Now it's time to remove the dead moss. It’s important to remember during this part of the project to take great care in not removing the grit on the shingles…so no heavy scrapping. Start with a stiff bristle push broom, and lightly go over the roof dislodging as much moss as possible. Use a paint scrapper to knock off what remains. Again, it's very important to remember to just knock it off…don’t scrape it off. This entire process also took less than a day to complete.
Believe it or not, it really is that easy!! So, with just a ladder, a garden hose, a good roof moss killer, a stiff bristle broom, a paint scrapper, and a little less than two days, you'll have a roof free from moss. It is now time to move on to step 2: installing zinc strips to make sure the moss doesn't start growing again.
