Do you know where your garden stops and your roof starts? Not only can it look unsightly, it could be doing a lot of damage to your home. The moss can 'lift' your slates as it grows, inviting in the weather into the woodwork - and all sorts of insects. Not only can this be unsightly it can also damage the woodwork - and this will cost you money to repair or devalue your property if left untreated. Do yourself - and your roof - a favour. Give it a fresh start with a clean slate.
