    Hi,

    On the north side of my house I have moss on the slate roof. I'm
    concerned that it's pushing the slates apart. My roof is 90 years old.

    How do I combat this problem?

    Thanks,

    Aaron

    If it doesn't leak ignore it. Otherwise, contact a slater (not a
    roofer) and get the right kind of help to rermedy the problem.

    He said Moss not Mold. Will bleach kill moss?
    And how does one wash a roof with bleach?

    I don't think that slate by itself would support moss growth. While it is
    possible that the slate is deteriorating to the extent that it is
    generating a growth medium, it seems more likely that debris is collecting
    on the roof and shade is protecting the moss from drying out. SO the
    question is whether there are increasingly large trees leaning over the
    roof where there were none before.

    A zinc strip at the top of roof is common where I live, Laundry bleach
    will kill it now but moss grows in debris , is roof covered by a tree
    and not steep pitch so it collects dirt. Mold or green coloring is
    common and no harm but moss to me means roof doesnt clean itself by
    rain, by moss you mean it is maybe 1/2" thick and it pulls up intact?
    My slate roof has green mold, but no buildup in thickness. Moss would
    be a problem. The only true moss I have or have seen grows on the
    ground. Roundup will kill it but take longer and cost more than
    bleach.

    Moss does not like pulverized lime, but that will color your roof
    white. The are moss killers you can apply.

    Thanks for all the responses.

    I like the inexpensive bleach solution, but won't my roof and back yard
    smell like bleach?

    I don't know if it's moss, but it's a moss like substance that grows on
    the spaces between the slates on the north side.

    Slates have two big nails holding them. 5ft of snow or a person wont
    budge them. Moss in between shouldnt cause harm, they lift a bit, look
    underneath to see if it grows under slates, minimal green growth wont
    hurt anything , you made it sound like the roof is covered with moss
    which to me means debris and dirt, then the roof wont breath and wood
    will rot, a photo is always a good idea. Bleach smells only a few
    days, a garden sprayer pumped up with a straight spray might reach
    8-10 ft

    I used to be able to buy Copper Sulfate for the garden, I cant now
    because its poisonous. Sprinkling copper, Zinc, and" metals" might
    require serious caution, I would not want wind blowing in my
    direction, and on a roof you can get crazy winds since they deflect of
    the house. Maybe in a liqued solution, but I used Copper Sulfate to
    Kill Trees, a dust mask is not good enough protection with CS.
