A roof valley is the intersection between a dormer wall and roof surface, or possibly the intersection between two separate roofing systems. This Trim is specifically used for a roof valley. It secures to each batten and on top of the flashing using 40mm galvanised nails. The Trims should be overlapped where they meet and be sealed with silicone.

 

Due to the high volume of water travelling down the valley a patented water drip and multiple outlet system runs along the trim.
