How do you fix the Onduline ridges?
Onduline has a range of ridges and verges available to match the different corrugated sheets and tiles. Follow the below steps to correctly install the ridges.
1 - Use a rafter to support the ridge.
2 - The ridge should be fastened at each corrugation of the overlapped sheet.
3 - Add an extra purlin when necessary if the distance between the last purlin and the ridge is too wide.
See full technical installation guide.
4 - Start fixing the ridge at opposite end of the roof from prevailing winds.
5 - Maintain 12 cm minimum overlap between ridge and ONDULINE sheet.
6 - Maintain 12.5 cm minimum overlapping between ridges.
7 - A ridge cap can be cut from exterior quality plywood to finish the ridge unit at the verge.
