Metal Roofing System installation Practices
Our metal roofing products can be used in both new and old construction. We recommend installation metal roofing systems over a solid substrate. Installation over strapping is also possible but can cause many issues. The following steps should be taken to prepare the metal roof for installation of any metal roofing panel.

Make sure there are no nails or other objects that might puncture the underlayment of roof panels.
- Check all details for possible roof penetrations which must be added to the roof prior to panel installation (vented ridge – plumbing stacks).
- Cover the roof deck with Nova Seal, overlaying 6″. When installing over strapping, run the felt parallel with the metal panels, making sure that the felt is tight.
Snap a chalk line along the gable end where the first panel will be installed. This line should be ½” away from the edge of the roof and square with the eave.
