Riverside damp and shaded gardens both play a part in how quickly moss and algae build up on roofs around Henley-on-Thames. Left unchecked, that growth can trap moisture against tiles and slates and start to affect their condition over time. Properties close to the river or surrounded by mature trees can see this happen more quickly than most.
