	2.2	SHEET METAL ROOFING
		A.	Performance Requirements:
	** NOTE TO SPECIFIER ** Please be aware that minor surface deflections known as oil canning are inherent in thin sheet metal skins. Factors such as reflectivity will amplify the oil canning appearance until the patina occurs. Also wide flat surfaces will show deflections readily.

These are normally a result of improper application.

		C.	Application:
			1.	Notch corner of the sheet and turn 3/4 inch (19 mm) edges (top and one end turned up and bottom and one end turned under) to form 3/4 inch (19 mm) flat seam. Paint one side and dry well before applying to roof with painted side down (Terne II only needs painting). Do not nail through sheets; attach with cleats.
			2.	Hook one end of cleat into the 3/4 inch (19 mm) edge formed on pan. Fasten cleat to deck and bend the other end of cleat over the exposed fastener. Lay pans according to the flow, i.e., placing the pan higher on the roof over the upper edge of the lower adjoining pan.
			3.	Stagger all joints. Seams shall be malleted down to form flat overlapping surface. Carefully mallet the seams to avoid buckling.
