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.
