Danelaw Pitched Roofing 
Zenon GRP Rooflights 
Dryseal Flat Roofing 
Secret Dry Fix Valley Trough
The Secret Dry Fix Valley Trough has been specially designed for where it is not seen when the roof is completed. When installed, it achieves the traditional close-mitred appearance expected from more traditional and historic projects. It is compatible with all slates and double lap tiles. Being manufactured from GRP, Danelaw dry valley troughs have the following benefits;
- A proven design omitting the more common
central upstand. - Light in weight and easy to handle
- 30 year service life guarantee
- Significant cost savings over a traditional
individually soakered or lead and mortared valley
installation. - No requirement for special eaves closure pieces.
- Removes the risk of lead theft as GRP has no
scrap value. - No harmful run-off or staining.
