On chipped coated roofing tiles the lichen gets rid of the coating and exposes the tile to corrosion.
If the expansion is authorized to go unchecked on interlocking tiles there is a threat the channels of the roofing can develop into clogged leading to leaks.
Also, roof moss stops the roof covering from drying out. This will deteriorate the paint on metal roofs and finally make concrete and clay tiles extra porous. The trouble is created even worse by frosts and cold climate situations. The moss/lichen retains drinking water which expands on freezing which can blister the paint. In serious scenarios it will crack roof tiles or lead to extreme pitting.

The strips need to be put at intervals down the roof to be certain adequate fungicidal clean addresses the roof. For an ordinary sized household one size alongside the ridge with a 2nd fifty percent way down the roof is adequate to hold the lichen down. Soon after a number of yrs the copper will acquire a inexperienced patina and the fungicidal qualities will be lowered. By scrubbing this patina absent the copper can be “reactivated”.
