Moss on my Roof: And the problems it causes


Is there Moss on my roof ?  It’s probably something that you don’t notice, or maybe you have seen and not really thought to much about?

Problems start when the moss, absorbs rain water and where there was once a secure, cemented joint, there is now a void allowing that water under your roof tiles and onto your waterproof membrane (if it is indeed waterproof), sitting there soaking into your roofing batten and gradually rotting them, compromising your roofs structural integrity and causing movement of tiles, where more rain water will get at the inners of your roof and worse, in some cases, allowing tiles to slip from your roof and onto the ground below.
