Divide the width or length of building by (3) to determine number of sheets needed for that section.

Example:  Building is 30' long then you would take 30/3=10.

Multiply number of sheets by length of each sheet.

Example:  10-13' sheets                   10x13=130(linear feet)

                 5-16' sheets                     5x16=80(linear feet)

                                                        Total=210(linear feet)

Multiply total linear feet by the current linear foot price to get total metal price. 

Trim and Accessories are figured seperately.

Multiply Total Linear Feet by (2.5) for 2' centers.

Multiply Total Linear Feet by (1.875) for 3' centers.

Multiply Total Linear Feet by (1.25) for 4' centers.

Example:  2' centers                     210'x2.5=525 screws

               3' centers                     210'x1.875=394 screws 

               4' centers                     210'x1.25=263 screws

(Ridge Cap) Multiply number of Ridge Cap by 30.

(Corners)  Total running feet equals number of screws.

Ridge Cap                                  5x30=150 screws

Corners                                     5x12'=60 screws 

(2" Fiberglass)--Multiply Linear Feet by (.03) then divide by (6) for number of rolls needed.

(Bubble Wrap)--Multiply Linear Feet by (.03) then divide by (7.5) for number of rolls needed.  

Example:   2" Fiberglass          210'x.03167=6.66/6=1.25 Rolls

                Bubble Wrap          210'x.03167=6.66/7.5=1 Roll

*Multiplying The Total Linear Feet by (.03) determines total square of metal.
