The Metal Panels and Trim for a Shed Roof calculator computes the total number of metal panels and lengths of trim needed to cover a single sloped roof based on the span, pitch, ridge length and the front and back overhangs.

INSTRUCTIONS: Choose units and enter the following:

• (L) Ridge Length (include rakes)
• (S) Span
• (P) Pitch (choose: flat, 2/12, 4/12, 6/12, 8/12, 10/12, 12/12, 14/12)
• (oH) Overhang (default: 12")
• (MoE) Margin of Error (added to the calculated Panel Length)
• (maxLen) Max Length of Panels

Metal Panels and Trim for Shed Roof (TL): The calculator returns the following:

1. Gable Trim: total length of gable trim, equals four times a gable length
2. Metal Panels:  number and length of metal panels for the roof. 
3. Metal Screws: number of screws needed to attach panels to roof.
4. Snow Guard: total length of snow guard, equals twice the ridge length.
5. Angle Trim: total length of angle trim (used as facia and on the ridge).
6. Purlins: number and length of rows of purlins for the roof
7. Area: area of the roof in square feet.

A Shed Roof is a roof with a single slope. Shed Roofs are used in simple agriculture buildings and state of the art modern buildings.  A Shed Roof can be made with trusses or rafters and can be covered will various waterproof materials including shingles, metal panels and tile.

Metal Roof and Siding Calculator

Functions for roofing and siding using metal panels and trim to compute the number of metal panels, trim and screws for various shaped roofs and walls based on the dimensions of the building.

• Metal for Gable Roof: This estimates the materials needed for a simple gabled metal roof based on the roof dimensions.
• Metal Siding for Gable End Wall: This estimates the vertical metal siding panels for a wall under a gable end based on the dimensions.
• Metal Siding for Gable End Wall with Door: This estimates the metal siding materials for a wall under a gable end with a door based on the dimensions.
• Metal Siding for Wall: This estimates the metal siding materials for a rectangular wall based on the dimensions.
• Metal for Dormer Roof: This estimates the metal panel and trim materials for one or more roof dormers based on dimensions.
• Metal for Gambrel Roof: This estimate the length and number of metal panels needed for a gambrel roof based on dimensions.
• Metal Panels for Gambrel Wall: This computes the number of vertical siding panels, their lengths and the total length of vertical panels on a wall under a gambrel roof. It also includes the total square feet and the number of metal screws needed at 0.75 screws per square foot.
• Metal for Hip Roof: This estimates the metal roof materials for a hip roof based on dimensions.
• Metal for a Pyramid Roof: This estimates the metal roof materials for a pyramid hip roof based on dimensions
• Metal for a Shed Roof: This estimates the total number of metal panels and lengths of trim needed to cover a single sloped roof based on dimensions..
• Metal for Shed (Roof and Walls): This estimates the total number and length of metal panels for the roof and walls based on the ridge length of the roof, the front and back heights, the width of the shed roof building and the front and back overhangs. See simple ag run-in below.
• Pole Barn Materials: This uses an estimated the linear feet of metal panels needed for a pole barn with a door way, and provides an estimated cost for the metal panels for the roof and siding based on a the dimension and cost per linear foot of panels.  
• Pole Barn Metal Roof and Siding Cost: This uses an estimated the linear feet of metal panels needed for a pole barn with a door way, and provides an estimated cost for the metal panels for the roof and siding based on a the dimension and cost per linear foot of panels.

Materials for roofs, walls and dormers include panels (number and length), panel cut angle, the number of required metal panel screws, lengths of ridge cap, gable trim, angle trim, snow guard, purlins (number and length), surface area and ridge and valley lengths where appropriate.

 

Ag Panel Pricing

There are several price points for metal roofing and siding, but the common Agriculture Panel (Ag Panel) is widely used and often the most economical. Ag Panel metal has reached the point where it is less expensive as a roofing material than common asphalt shingle.  For this reason, Ag Panel pricing is provided from a survey for convenience. 

The C-Lok, Ag Panel, G-Rib price survey includes the following for the most recent pricing surveyed:

• Date Survey: 3/7/24
• Source of Pricing Source: CN Metals
• Cost per Unit:
  • [$3.19 USD/ft] - Panel (36" wide) - dollars per linear foot
  • [$0.09 USD/screw] - Screws (with seal gasket) - dollars per screw 
  • [$1.74 USD/ft] - Ridge Cap - dollars per linear foot
  • [$1.84 USD/ft] - Outside Corner (trim) - dollars per linear foot
  • [$1.25 USD/ft] - Snow Rail - dollars per linear foot
  • [$2.85 USD/ft] - Drip Edge - dollars per linear foot
  • [$0.2 USD/ft²] - Fanfold Insulation - dollars per square foot
