Moss on roofs can cause problems not big to start with but if it continues without any maintenance the problem grows bigger just like the moss on your roof. Wood rotting and the obstruction of drainage points can become a issue and it can also reduce the lifespan of your roof. Most roofs do experience moss or lichen growth, small patches are fixable quiet easy but if it spreads these are some of the things they may happen, Moss can break off and fall into gutters and downpipes blocking your drainage systems which if not cleaned out can lead to replacement of guttering. Moss also is like a sponge absorbing moisture which in turn makes your roof constantly wet, if the moisture travels to the underneath tiles it may rot the wooden components of your roof, then this could result in structural integrity being comprised and costly repairs, having a pitched roof you would think it would be ok, but think again moss is everywhere, the main benefit of having a pitched roof is easy drainage of precipitation due to the sloped angle, moss can however hold onto the water by absorbing the moisture and not letting it drain away.
Removing moss from tiles
Be cautions when using chemicals like moss killer and always where the correct clothing and protective accessories, be mindful the chemicals can run off your roof and have the potential to contaminate groundwater. Try using a brush and gentle brush the moss from the tiles given the area is not large and manageable. Also be mindful when using a pressure washer as this could lead to further damage of your tiles and the water can leak into your roof interior making it soaking wet.
Prevention of Moss
One of the best ways to stop moss growing is by installing copper ridges to your roof, the rainwater falls onto these ridges , a coppery residue is released and runs down the roof discouraging moss growth. Maintenance and cleaning your roof is also one the best things you can do.
