mossy roof

[ssaamm]

I was cleaning the gutters last week and noticed there were some decent-sized clumps of moss on the north side of the roof. I could loosen them up and remove a few of them with the leaf blower. I assume that it's a good idea to remove them if possible. Could a person spray a little dilute bleach or something else to kill them off or loosen them up? Appreciate any words of wisdom. Thanks. Go Vikes. A miserable season would be a little better with two wins over the pack. thanks

manards or home depot have zink strips that you nail under your cap shingles. the zink is suposed to kill the moss. just an idea........

yeah, first you are going to wanna do what Hawk said then spray the diluted bleach on the roof. It should be able to take care of itself after that. let them die and they should come off by themself. Thats funny you ask this question because the exact same thing was on "This Old House" this weekend. If you put the zinc strips down remember to put silicone on the nail heads.

you may want to test an area on your siding etc. with the bleach, it may change its color.

I had this same problem on my garage a few years ago. I found a product made for this problem in the Home & Garden section of our local Menards/Home Depot. It came in a spray bottle that you attach to your garden hose. Its sprayed on the roof and over the course of a week or two it killed the moss. It didnt hurt any of the grass or surrounding plant life but you are suppose to try and keep it off such stuff....so its best to do it on a calm day. Sorry, I cant remember the name of the product....

I just saw it on "this old house" Saturday, also!!

my 2 cents as an x and on the side roofer- zink strips like you guys said. Another thing to keep in mind besides sealing the nail heads is that some of it is sharp as all you know what. I learned the hard way but it only took once!

I re-roofed my parents house 5 years ago (cedar shingles) and we put two courses of zinc strips on the roof. One row on each side of the peak and one row halfway to the d-edge. He used to have lots of moss on the old shingles and previously had to use the bleach method to keep it off. 5 years later the shingles still look brand new. We also cut back a lot of the tree limbs that were near the roof so that it would dry off more thoroughly. Hope this helps you.
