Moss On Roof Tiles Is It A Problem

If you remove moss from the roof then you will reduce the possibility of tiles suffering from winter cracks.

Moss on roof tiles is it a problem. Ultimately moss growth on a roof can result in costly repairs and can also reduce the lifespan of your roof. Moss on roof tiles can cause multiple problems such as wood rotting and the obstruction of drainage points. Avoid any aggressive cleaning methods that might damage the roof surface. The presence or absence of sunlight dictates the amount of moss or algae growth.

The presence of algae on the roof is an indicator that this roof area is in a shaded spot where you may want to be alert for development of moss or other roof problems but the level of damage from algae is probably low even less than that caused by lichens. Keep your trees well trimmed to lessen the debris that falls onto your rooftop. Shaded areas exposed to frequent damp cool weather will quickly encourage moss to grow on your roof. Fortunately for us the very nice roofing man we called to investigate the problem very quickly discovered what the problem was and fixed it without even charging us.

We had a problem where in very heavy rain the moss build up in the valley was causing water to back up and go under the tile above.
