How does moss grow on roof tiles.

The presence or absence of sunlight dictates the amount of moss or algae growth. If you have moss on your roof it s likely because your roof is shaded by trees or other structures allowing moisture to linger and moss to grow. When you are spraying on a roof always start on one side and walk backwards away from where you have sprayed. Moss growing under roof slate and tiles can push the slate out of position allowing rainwater to seep into the roof structure.

You also should consider pruning any tree limbs that overhang the roof natural sunlight is a powerful moss. In addition the water trapped by the moss pools in gaps between your roof s tiles and as that water freezes and thaws it can pull the tiles apart causing even more damage. If the moss growth is allowed to develop further it can become a problem for the roof for a number of reasons. If you allow large patches of moss to grow on your roof these patches hold water against the surface of the roof which can cause the roofing materials to rot.

Most roofs will experience moss or lichen growth and small patches of growth are usually not a problem. While moss doesn t have real roots it has tiny protrusions that look like roots and it will form its own soil by collecting dirt and debris from the air. The more water and the more debris the greater the chance of moss growth. Moss is probably the easiest growth on your roof to identify.

It looks like a little patch of grass or maybe a really big patch if you ve let it go for a while. Moss acts like a sponge absorbing large amounts of moisture and resulting in your roof being constantly wet. In this case add a copper strip at the midway point down the roof too.
