BEGINNING THE PROJECT STANDARD EAVE TRIM INSTALLATION 1. Install the eave trim by sliding it underneath the underlayment and securing it to the roof surface with wafer head screws on 5’ centers. 2. There are no screws or nails to be placed in the exposed fascia of the trim. 3. At the corners, cut the eave trim 1 1/2” long and prepare the ends with tabs to receive the gable trim. NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
STANDARD EAVE TRIM INSTALLATION WITH GUTTER 1. Install the eave trim to the substrate with wafer head fasteners at 5’ O.C. 2. Position the roof panel so that the down slope end matches the dimension called for on the erection drawings. 3. Attach the roof panel with #10 x 1” woodgrip screw. (Refer to screw placement table). 4. Attach the roof panels at the eave with #10 x 1” woodgrip screws - Reference Type 1 Fasteners. 5. Attach the gutter with #14 x 7/8” lapteks @ 12” O.C. 6.
STANDARD ADJUSTABLE GABLE & STRIP INSTALLATION 1. Starting at the corner, install the adjustable gable trim along the sloping gable, placing it on top of the underlayment. 2. Attach with wafer head screws 5’ on centers (adjustable strip applied after valley trim). 3. Slide gable trim over eave trim at corner. 4. At the peak, one gable trim should be cut vertical to the ground and overlap at the junction of the two gable trims. NOTE: Alternate trim profiles are acceptable using the screw pattern shown.
HIGH SIDE RESIDENTIAL EAVE TRIM INSTALLATION 1. Attach the high side trim (#0802) to the fascia with woodgrip screws on 5’ centers. Make sure the 6” side of the trim is on the rooftop with the hem resting on the highs. 2. 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 cut and folds. 3.
VALLEY PANEL AND TRIM INSTALLATION 1. Start at the low end, trim and place the valley flashing. The valley end should overhang the eave trim 1”. 2. If there is an end lap required in the valley pieces, caulk and lap at least 8”. 3. Use wafer head screws on 5’ centers to secure the valley in place along the outside edge. 4. Hem the edges of the valley over the eave trim, after trimming the center “V” back 1” to align with the edge of the eave.
STANDARD RIDGE ROLL and HIP INSTALLATION 1. Lay a piece of the #0221 ridge roll or hip in position, making sure it is centered and in the correct position. (Refer to step #7 for end capping instructions) 2. Temporarily fasten the ridge roll in place at one end with a lap screw, positioning the screw through the hem of the ridge roll, centered on the corrugation. 3. Position the corrugated closure on the sheet. 4. Attach with (1) lap screw, centered on the corrugation, 12” O.C.
ENDWALL TO ROOF FLASHING INSTALLATION 1. Insert the endwall flashing (#0724) behind the existing wall counter-flashing and attach to the wall using appropriate fasteners. Make sure the receiver hem of the endwall flashing is resting on the top of the roof sheet rib. If required, cap the ends of the trim by cutting and folding a tab. 2. If there is no counter-flashing, install counter-flashing using appropriate fasteners. 3. Position the corrugated closure on the roof. 4.
SIDEWALL FLASHING INSTALLATION 1. Apply butyl tape continuously to top of corrugation. 2. Insert the sidewall flashing behind existing counter-flashing and secure to the top of corrugation with lap screws. 3. If there is no existing counter-flashing, install counter-flashing to wall with appropriate fasteners. NOTE: Alternate trim profiles are acceptable using the screw pattern shown. 19 Details are subject to change without prior notice.
ROOF PITCH CHANGE INSTALLATION 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. Position the corrugated closure on the roof. 4. Attach using one lap screw, centered on corrugation, 12” O.C., through the hem of the transition flashing and corrugated closure, into the panel.
STANDARD PANEL ENDLAP 1. Ensure the lower panel is installed completely (except for the top fasteners). 2. Install the butyl tape 10” from the top of the lower panel. Do not remove the paper backing from the butyl tape until upper roof panel lap and the top dimension have been confirmed. 3. Remove paper backing from the butyl tape. 4. Position and place upper panel so that a 12” lap is achieved. 5.
CHIMNEY INSTALLATION CHIMNEY FLASHING - UPHILL AND DOWNHILL UPHILL 22 The uphill flashing will be 4” wider than the width of the curb (2” on each side). Cut an 1/8” slot in the two uphill corners of the panel slightly wider than 2 1/16”, so the uphill flashing can slide through the two slots. UPHILL DOWNHILL 1. Trim both ends of the uphill and downhill sides of the flashing as indicated. 2. Slide the uphill flashing into the slots of the roofing and apply liberal amount of tube caulk.
CHIMNEY INSTALLATION CHIMNEY FLASHING - SIDE 1. Trim and bend the right side flashing as indicated. 2. Trim the left side in a similar fashion. NOTE: Alternate trim profiles are acceptable using the screw pattern shown. NOTE: The left and right side flashing are mirror images of each other. SIDE SIDE SIDE 23 FLASHING - VENT Procedures: 1. Trim the opening in the flashing to 20% smaller than the pipe diameter. 2. Slide the flashing down over the pipe. 3.
