SR2 ROOF PANEL INSTALLATION
18.0 ROOF PANEL END-LAP FASTENING
18.1 When the roof system contains more than one course / row of panels the following steps should be observed for the fastening of the panel
end-lap.
18.2 Stagger the panels per the panel installation sequence outlined in section 16.9. Install the panel fasteners per section 17.0 (except for
fasteners at the end lap support).
18.3 Use metal snips to cut off the exposed metal edge at the side joint face (6") at each side of roof panel for proper nesting of upper course of
overlapping SR2 roof panel.
18.4 Prior to placing the upper course / row of panels, the end-laps of the lower course panels must be caulked. The caulking on the end-lap
should be married to the caulking in the panel side overlap. Apply caulking immediately prior to upper course panel installation.
Notes:
1. All surfaces to be caulked must be clean and dry.
2. Apply end-lap seal to panel surface to be lapped.
3. Sealant strips should overlap one another side by side (minimum 1").
