Not just about appearance
Nothing looks worse than moss growing on your roof or weeds sprouting from the gutters.
But it's not just about appearance. Moss growth can encourage moisture to linger on the roof and track beneath the slates and tiles. Similarly, weed growth can cause a build up of soil and debris that blocks gutters, harbours water that causes rotting in the supporting timbers and can be a breeding ground for pests and vermin.
Old concrete tiles are particularly susceptible to surface damage caused by moss algae attack.
P W Contractors has specialist equipment to clear and kill moss, lichen and other vegetable matter that is damaging your roof.
