Use GRP Dry Valley troughs for roof pitches of up to 60º. Where feasible, we recommend the use of a suitable valley board. The underlay material and battens should be fixed in accordance with standard roofing best practice with a batten running the length of the valley on each side to accommodate the external raised water bar section.
