ROOF PITCH CHANGE INSTALLATION
Details are subject to change without prior notice.
1. Apply lower panels.
2. Install the transition flashing (#1486) making sure the bottom portion of the flashing is at the same pitch
as the lower panels. Attach to decking 1” from top of flashing with wafer head screws on 5’ centers.
3. Install outside closure on top of the lower panel. Make sure the closure is in line with the lower flange
of the transition trim.
4. Attach using lap screw, 12” on center at the rib.
5. All trim end laps should be at least 4”. Secure to the overlapped piece with caulk and stitch screws.
6. Cap the ends of the trim by cutting and folding a tab that attaches to the gable trim. Capping is usually easier to
do before the trim is installed. If done after the trim is installed, be sure and leave 6” of the trim overhanging to
allow enough material for the cut and folds.
7. Before applying the upper panels, place a row of butyl tape continuously along the trim at a point where the
screws holding the lower end of the upper panel will go through the butyl tape. This is usually 4” uphill from the
bottom of the upper sheet. Use eave screw pattern.
NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
