23. Hips
Install tile battens to suit gauge of tiles, ensure that tile battens project to centre line of hip tree.

|
|
Step 1, Measuring for the Hip Tile
Measure from point (A) to (B). Measure from point (C) to (D), write down these measurements minus 5mm off both distances, this will be the set distance to make your cut at.
|
|
Step 2, Marking Out Your Hip Tile
Markout the same measurement (A) to (B) & (C) to (D) on to a tile. When transferring measurements to tile ensure measurements correspond with the position of the underlying tile batten (see batten intersection drawing below).
Scribe a line from (B) to (D), this will be the bending point for your hip tile.

Step 4, Install ridge cap to hip
The methods for installing Decra D ridges with or without Universal D ridge ventilators is the same in principle as shown for the ridge detailing earlier in this guide.
NOTE: When installing the Decra D Ridge/hip Sealing Strip make a neat incision at each intersection of the sealing strip with the nose of the tile to allow the sealing strip to dress fully into the step between each course of the tiles.

24. Forming A Three Way Intersection At Hips
To form a three way intersection using D Ridges cut and fold tabs and flaps in ridge tiles as shown ridge sections A, B & C above. Install ridge section A followed by ridge section B then C on top. Nail ridge caps into position and touch up with Decra finishing kit.

28. Valleys
Lay valley boards flush with rafter level and install valley runner batten to each side of valley.
If needed install an additional packer batten, parallel to side of valley runner batten, so as to support sweep of tile batten.
Install tile battens to suit gauge of tiles, ensure that tile battens sweep up and over valley runner batten. Cut battens to rake projecting over valley to 65mm short of centre line of valley.

Step 1, Measuring for the Valley Tile
Measure from point (A) to (B), Measure from point (C) to (D), write down these measurements as this will be the set distance to make your bend at
|
|
Step 2, Marking Out Your Valley Tile
Markout the same measurement (A), (B), (C) and (D) to a tile. When transferring measurements to tile ensure measurement correspond with the position underlying tile batten (see batten intersection drawing below).
Scribe a line from (B) to (D), this will be the bending point for your valley tile.
Scribe an additional cut line on to the tile to allow for a tile downturn at the valley.
NOTE: When forming a downturn in the tile take a measurement from top of leading edge of tile batten to valley surface and allow for tolerance in fit to avoid the downturned edge of the tile making any contact with valley surface.
