Moss on roof tiles is it a problem.

Moss absorbs and retains water. 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. Moss on roof tiles can cause multiple problems such as wood rotting and the obstruction of drainage points. 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.

Roof moss prevention if the above sounds like too much of a hassle which honestly it likely does then know that the most effective method is to prevent the problem of moss on your roof in the first place. The reason being in most instances moss on roof tiles is rarely a problem and only needs to be removed if it is blocking gutters outlets and other drainage points on the 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. If you remove moss from the roof then you will reduce the possibility of tiles suffering from winter cracks.

Ultimately moss growth on a roof can result in costly repairs and can also reduce the lifespan of your roof.
