15. INSTALLING HIP ROOFS
15.1
ROOF PANELLING
If using plywood panels above rafters, the installer should ensure that there is a ventilation gap of 25mm at the apex ridge area
to allow for interstitial condensation to escape. At the hip beams please ensure that a minimum gap of 20mm is provided to
compensate for both ventilation and panel expansion.
Allow 25mm gap
Allow 20mm gap
FITTING FELT SUPPORT TRAYS
Fix the universal felt support tray to the plywood ensuring the edge of the tray fits to
the edge of the plywood panels at the eaves. Trim the tray at the hip beam as shown
- use the edge of the plywood panel as a guide.
Ensure that the trays are overlapped (see page 11 for full details) by at least 100mm
to ensure water tightness.
