Dry Fix Hip Fixing Instructions
1. For an unventilated dry hip system, install the underlay as normal. For a ventilated dry hip system, lay the underlay and battens, cutting the underlay 30mm short of the hip on both sides of the hip, to allow for ventilation. Ensure the ends of the battens are securely fixed where they meet the hip.
2. Hip batten supports in 50mm x 50mm timber should be screw fixed at the eaves and apex, and spaced along the line of the hip rafter, in between the tiling batten spaces as shown. Supports could be constructed from 2 x 25mm tiling battens.
3. Screw fix hip batten constructed from 50 x 50mm timber to the supports. Complete tiling, cutting the tiles neatly against the hip batten. No cut tiles should be more than 30mm from the hip batten. Small tile cuts should be secured mechanically or by using a proprietary adhesive or other fixing method.
4. Working from the eaves, secure the Dry Fix Ventilated Ridge & Hip System in place centrally over the hip batten using corrosion resistant nails or staples. Roll out along the hip batten and fix at 300mm centres. Remove protective paper from the adhesive strip and press down firmly onto dry, clean tiles all the way up both sides of the hip. A hip carrier is available to assist with aligning the hip tiles when used with profiled tiles (available to order separately).
5. Using a 100mm screw provided, secure the block end hip tile to the hip batten (it may be necessary to drill a hole in the hip tile approximately 30-40mm from the block end for this purpose). Fix hip tiles up to the apex using the 100mm screws and fixing plates provided. An optional screw sleeve is included if the user perceives that there may be a risk of light bleed between hip tiles.
6. At the apex close mitre the hip and ridge tiles, drill and secure to the hip and ridge batten using the 100mm screws provided. If the Dry Fix Ventilated Ridge & Hip System is not used on the ridge, continue the roll 200mm onto the ridge, in place of the standard lead saddle detail.
