Roof Valleys FAQ
What is a roof valley?
A roof valley is formed where two roof slopes meet. Water collects in the valley to flow off the roof into the gutter and downpipe.
Why do I need a roof valley?
The roof valley is necessary for removing excess water and prevents prolonged exposure to moisture. This protects the roof from damage and fights off mould and algae build up.
