How does moss,
mould and lichen affect a roof?

The buildup of moss, mould and lichen on a roof affects roof surfaces in a number of ways. Lichen is by far the worst offender. Apart from being an unsightly and unwanted guest, it also has roots (rhizines) that anchor and etch into the roof, causing irreparable damage.

The lichen disaggregates surface structures and coatings, greatly accelerating oxidation and rust. Lichen also holds moisture against the roof surface like a sponge long after the clean roof has dried after rainfall or condensation, adding to the speed of deterioration.

Other types of mould have their own detrimental effects by creating acidic byproducts that deteriorate roof surfaces and affect the aesthetic and safety of a roof.
