Installation of R-Panel / PBR Panel (Exposed Fastener) Roof Panels
The three most important factors to remember when installing any metal roof panels are:
1) SAFETY IS PRIORITY #1 – Follow All OSHA safety guidelines
2) Panels must be installed square
3) Fasteners must be installed in the proper location.

R-Panel / PBR Panels installation should begin at the gable end of the roof. R-Panels / PBR Panels are installed from right to left. To begin, measure one full panel width in from the edge of the roof. At this point chalk a line or pull a string from ridge to eave (avoid getting chalk on panels— it may stain the panels!). Place the leading edge of the first panel along this line. It is extremely important that this panel be laid square to the eave and ridge so that the remaining panels will line up square. Depending on crew size, it is wise to have a person at the eave and one at the ridge to ensure that the proper panel coverage is being maintained and the panels are running squarely across the roof. In applications where end-lapping is necessary, the upper panel on the slope should lap over the panel that is lower on the slope. Lower sloped roofs require a greater amount of panel overlap (6” minimum). All end-lap applications require two horizontal rows (across the panel) of butyl sealant tape and proper fastening to provide a maximum water seal. An overhang of 2 to 3 inches is recommended to provide a drip edge, while only 1 inch overhang is necessary where gutters are used. The open panel ribs at the eave should be sealed with inside closures and one row of butyl tape.
Trimming and Cutting Steel Panels
The best device for cutting steel panels across the profile is either a portable or hand shear, double cuts or a nibbler. Tin snips may also be used. When using Tin snips, be aware; they do come in right-hand and left-hand models. Be careful when using a nibbler; nibblers do have a tendency to leave hot metal particles that can burn paint surfaces or leave rust marks on panels and trim. The same is true of any filings left on the roof caused by the application of screws. Care should be taken to brush all such particles from roof surfaces after application.
To cut panels lengthwise: Use a straightedge or chalk a line to indicate where to cut. Depending on the length of cut, either a double cut, or nibbler is suggested. For short cut, tin snips can be used.
CAUTION! Clean All Metal Shavings and Particles Off of Roof To Avoid Rusting and Rust Stains
