Installation Guidance - Decra Plus

1. Fix two tiling battens 50 x 25mm side by side at top of ridge, using galvanised nails. 2. Secure top course of tiles using 4-no Decra Plus Nails driven through the downturned nose of the top course into the battens.
3. Nail additional 50 x 25mm batten, with Decra ‘D’ Ridge Sealing Strip attached to underside, onto the top course of tiles in a position to suit the fitting of the Decra 0.43mm ‘D’ Ridge Cap.
4. Fold Ridge Cap to shape and fit over batten (above) and fascia.
5. Secure Ridge Cap with 4-no Decra Nails/Screws both sides. The procedure for installing the monopitch ridge is essentially the same as the detail for the ridges NOTE: Where roof pitches exceed 35° it may be necessary to adjust the return angle of the downturned leg of the D Ridge cap and use an alternative size of ridge fixing batten. NOTE: Decra D Ridge Caps are tapered to allow for laps. Overall length of ridge cap 1280mm, lap each ridge cap 80mm to provide 1200mm overall length of cover.
