Moss on roof

Discussion in 'Misc DIY' started by Stephen Spearey, Dec 20, 2005.

  1. I,ve just bought a bungalow and the roof is covered in moss. Can anyone tell
    me the most likely reason why I have more moss than any other properties
    nearby? The tiles are concrete as are most in this area.

    What are the likely problems caused by roof moss?

    All advice welcome.

    Thanks,

    Steve

    We and our neighbours all have moss on the roofs our houses. One of them
    pressure hosed it (from the top) and that cleaned it for a short time but it
    is now back. Another brushed it off and again it has returned. I had the
    tiles taken off my roof, they were all cleaned and put back and again the
    moss is now appearing again. I fitted a copper wire along the ridge and
    that seems to be helping, copper sulphate will kill moss.
    I fitted gratings in the gutters to stop the moss going down the rain water
    pipes but now have to clean them out regularly. I would not do that again
    as the clumps of moss do not really choke the drains.
    The moss grows more quickly on the shaded sides of the houses.
    Do not think that you can stop it.

    The reason moss grows on a roof is the type of tile, roof pitch and
    vegetation area. Any roof tile constructed of concrete laid on a low pitch
    slope, after about 10 - 15 years will grow moss. What happens is the cement
    starts to disintegrate and releases the gravel and sand content, which
    intern fills up the water channels into which moss gets a foot hold. Certain
    soft hand made will also grow moss. This type of tile as small air pockets
    through out the make up. When these get filled up with dust then moss
    grows. North and north east elevations seem to grow moss more and if the
    area is surrounded with trees this is a natural element for moss growth.
    You can scrape off with a flat garden hoe, put copper wire on the roof even
    take off all the tiles clean them and put them back but you wont stop it for
    long, you can even spray with moss killer if the enforcement people don't
    mind it getting into the fresh water table. Cleaning and spraying with a
    surface
    sealer is not a good idea, one small hole in the sealer and water gets in
    the roof cant get out and there is a leak and will take some finding.

    I've got moss on my roof and I keep it down with Pathclear. This is far more
    effective than Mosskiller, which I find useless. If you leave the moss on
    and spray it there will be something for the chemical to bind to and last
    for some time. Mind you, mine is a thatched roof, but that should change the
    issues.

    All these solutions to a problem which isn't a problem. What harm does the
    moss do?It certainly looks pretty. And it may also insulate the roof too.
    Leave it be.

    I agree with you in the case of a tile/slate roof. But mine is thatched and
    I'm not happy with moss growing on the reeds. I feel they will rot away more
    quickly.

    I live with mine too and simply clear the gutters of all debris including
    leaves and such when needed.I have never experienced any kind of problem
    from having moss on my roof and wasn't away that it caused any problem at
    all.

    Might be worth contacting a thatcher to ask their advice on whether it is
    harmful and what a solution might be.

    Moss can be a problem as the roots can absorb water and freeze in the
    Winter, dislodging tiles.
    We have a very effective solution, a spray that will remove the moss
    and its roots within a few hours, also discouraging its regrowth.
    You may like to look at our specific page at

    If you need any further advice you can also contact me directly.
