Pitched Roof Mount Checklist

Inspect roof and, if necessary, replace it prior to installation
Use stainless steel and/or aluminum hardware (rails, supports, clips, etc.)
Use flashing and/or appropriate sealing for every roof penetration
If necessary, reinforce roof with spacers or sistered rafters
Use stainless steel lag screws with sufficient rafter penetration for loading specifications
Make sure rail supports (standoffs, L-feet, or S5! clamps) are appropriately spaced for all loading considerations
Choose rail and module clip color to match module frames
Make sure rail and modules are properly grounded (Wiley WEEB, Unirac UGC-1, or Ilsco lay-in)
Make sure that all mid-clips and end-clips are tight and square, and the appropriate height for the module frame
