The following steps should be taken when installing
ASC’s Light Gauge Roofing over existing roofing:
1. Inspect the roof for damage and make the necessary
repairs to achieve a flat plane for the metal roof
panels. Wood shingles should be removed.
2. Secure any warped or loose roofing.
3. Make sure that there are no nails or other objects
protruding from the roof that might puncture the new
underlayment or the new roof panels.
4. Remove all moss and other debris from the roof.
5. Cut off any overhanging roofing flush with the roof
deck and remove all hips, ridge caps, and penetration
flashings.
6. Metal debris/shavings should be removed from the
roof progressively and daily to prevent immediate
corrosion and scratching of the top coat.
7. Follow the directions on page 4, #2 through #5 on roof
preparation.
