20.12 After drilling or cutting panels, always remove metal chips and foam dust that has fallen on panels or trims.
20.13 If the roof system consists of one course / row of panels, then proceed to the next panel and repeat steps 17.7 through 17.12 until the
roof is complete. If the system consists of more than one course / row of panels, do not fasten the panels to the steel supports at the
end lap and refer to section 13.0 for HR3 roof panel end lap support.
20.14 After all panels are installed, fasten the eave, rake, and peak trims, respectively. The trim should be fastened as shown on the shop

21.0 ROOF PANEL END-LAP FASTENING
21.1 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.
21.2 Following the panel installation sequence as outlined in section 16.0, the lower course panels should be installed first. Install the panel
fasteners as described in section 17.0 (except for the fasteners at the end lap support).
21.3 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").
