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 #9 x 1” woodgrip screw. (Refer to screw placement table). 4. Attach the roof panels at the eave with (6) #9 x 1” woodgrip screws - (6) per panel. 5. Attach the gutter with #14 x 7/8” lapteks @ 24” 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.
STARTING AND ENDING PANEL INSTALLATION Starting Panel 1. Apply adjustable strip as previously instructed. 2. Remove the first rib of the panel, making a straight cut the length of the panel. 3. Apply butyl tape continuously down the length of the adjustable strip, covering the wafer head screw. 4. Insert the cut edge of the panel into the strip, making sure the panel is seated fully into the strip. 5. Attach the panel to the roof with #9 x 1” woodgrip screws on the required centers. 6.
HIGH SIDE RESIDENTIAL EAVE TRIM INSTALLATION 1. Ensure the roof panel is installed completely. Reference the erection drawings for the top dimension to ensure correct installation. 2. Install the outside closure on the top of the roof panel, make sure the closure is in line with the extended flange of the high side eave trim. 3. Install the high side eave trim. 4. Attach the high side eave trim with lap screws @ 12” O.C.
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. Ensure the roof panel is installed completely. Reference the erection drawings for the top dimension to ensure correct installation. 2. Install the outside closure on the top of the roof panel. Make sure the closure is in line with the extended flange of the ridge roll. 3. Repeat the above steps on the other side of the ridge making sure that the flanges of the ridge roll line up with the placement of the closure. 4. Install the ridge roll. 5.
ENDWALL TO ROOF FLASHING INSTALLATION 1. Insert the endwall flashing (#0726) 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. Remove the hems before making the folds. 2. If there is no counter-flashing, install counter-flashing using appropriate fasteners. 3.
SIDEWALL FLASHING INSTALLATION 1. Install the butyl tape to the top of the roof panel. Make sure the tape is running parallel to the panel ribs and is in the correct location to line up with the extended flange of the roof transition trim. 2. Insert the sidewall flashing behind existing counter-flashing with the extended flange centered over the butyl tape. 3. Attach the transition trim with #9 x 1” woodgrip screws @ 12“ O.C. 4.
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. 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”.
STANDARD PANEL ENDLAP 1. Ensure the lower panel is installed completely (except for the top fasteners). 2. Install the tape sealant 10” from the top of the lower panel. Do not remove the paper backing from the tape sealant until upper roof panel lap and the top dimension have been confirmed. Reference the erection drawings for the top dimension. 3. Position the roof panel so that a 12” panel lap is achieved. 4. Remove paper backing and compress the sealant between the upper and lower roof panels. 5.
CHIMNEY INSTALLATION CHIMNEY FLASHING - UPHILL AND DOWNHILL UPHILL 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 26 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. SIDE 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 27 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.
