<br />Cutting
<br />
<br />Because tho bottom side is flatter, it is recommended that roofing and siding be cut from the bottom,
<br />A power saw, nibbler, snips, or profile shears may be used.
<br />Metal filings from cutting to length or for roof penetrations will create rust and cause serious appear-
<br />ance problems. Be sure the roofing and siding surfaces are free of all such filings.

<br />
<br />Storage Instructions
<br />
<br />If metal roofing or siding is not going to be used immediately, it should be stored in a dry area. It
<br />should be unbundled and slood on end against an interior wall,
<br />If materials must be stored outside, protect with canvas or waterproof paper, Allow for air circulation,
<br />do not cover air tight.
