How do I calculate corrugated metal roofing?

Multiply the length of the roof by the width to establish the surface area in square feet. For example, if the length is 21 feet and the width is 10 feet, the surface area is 210 square feet — 21 times 10 equals 210. Determine the width and length of the metal sheets to be used.

How many sheets of corrugated metal do I need?

Corrugated metal is 36 inches wide. Divide the length of your roof by the width of the metal. In our example we will use 24-inch standing seam roofing, so we will divide 360 inches by 24, which equals 15. This is the number of metal panels needed for one side of the roof.

How is corrugated metal measured?

Length and Width

The width is measured simply straight across the top of the sheet, from edge to edge, to indicate the coverage width of the sheet. It does not follow the peaks and valleys of the corrugate. The two most common widths are 26 and 36 inches. Other standard widths include 24 and 39 inches.

How many inches do you overlap metal roofing?

Install Metal Panels

Align the first metal roofing panel so that it overlaps the edging by 1/2 to 3/4 of an inch and is square to the roof line. Be sure the larger edge is laid so that the small edge of the next panel will overlap it.

How much should roof sheets overlap?

The product must be overlapped at the sides, not less than 1.5 corrugations. It is generally considered good practice to use fasteners along side-laps; however, when cladding is supported as indicated in maximum support spacings, side-lap fasteners are not usually needed for strength.

SHEET SPECIFICATIONS

Our traditional corrugated roofing sheets are galvanised steel and available in three gauges (thicknesses): 0.4mm, 0.5mm and 0.7mm. The corrugations in these sheets are 3″ (76.2mm) from peak to peak and will direct any rainwater away from the building.

How do you calculate the area of a roof?

To find your roof’s total square footage:
