Steel sheet roof, also called corrugated metal or standing-seam roof, is frequently used on utility buildings, garages and houses in areas that receive heavy snowfall. The roofing system contains individual panels with contoured overlapping borders that offer weather resistance in which the panels meet. To figure out the amount of material required, it is required to have the building plans or the aid of somebody who’s proficient at working on a framed roof.

Position an extension ladder against the edge of the roof at one end of a run that will be measured. Extend the top section of the ladder until the uppermost level is at least 24 inches above the edge of the roof to ensure stability. Skip this step if the building plans are available, as you are able to get dimensions from these plans.

Measure across the lower edge of the roofing from end to end and notice the measurement as the width of the section. Consult with the diameter of the individual sheets to be used, such as 24 inches or 36 inches, and convert the measurement to feet. Divide the diameter of the roofing section by the diameter of these sheets in ft to ascertain the number of sheets necessary to cover the section from end to end.

Measure in the lower border of the roof to the peak, and notice this measurement as the growth of the section of the roofing. Determine the length of the steel sheets based on the upswing of the roofing. For instance, if the rise is 14 ft, 2 rows of 8-foot-long sheets are utilized, along with the upper row of sheets overlaps the lower row 24 inches when installed.
