The Metal Siding for a Wall calculator computes the number of vertical panels and other metal siding materials for a rectangular wall based on the dimensions.
INSTRUCTIONS: Choose units and enter the following:
- (H) Height
- (L) Length
- (PW) Panel Width (default 36"). This is the coverage width and not necessarily the measured width of the metal panels.
- (OX) Adder to Panel Length. If you want the panels to have extra length.
Metal Siding for Wall (m): The calculator returns:
- (TA) Area: Total surface area of wall.
- (nS) Number of Screws: Total number of metal screws based on 75 screws per 100 ft2.
- (nP) Number of Panels: This is the number of panels needed.
- (lP) Length of Panels: This is the length of the panels including the adder (OX)
- (TL) Total Linear Feet: This is the total linear feet of panels needed.
However, these can be automatically converted to compatible units via the pull-down menu.
The Math / Science
Because it is better to have too much and to cut it, than not enough, an additional 3" are added to the panel lengths.
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.
- Screws for Metal Gable Roof: This estimates the number of metal panel screws needed for a gable roof based on roof dimensions.>
- Screws for Metal Siding on a Gable End: This computes the number of metal panel screws needed for metal siding for a wall under a gable roof end based on the dimensions.
- Screws for Metal Siding on a Gable End with Door: This computes the number of metal panel screws needed for metal siding on a wall under a gable roof with a doorway based on the dimensions.
- Screws for Gambrel Metal Roof:
This computes the number of screws to attach metal panels needed for a gambrel roof based on the dimensions. - Screws for Metal Siding Wall: This computes the number of metal panel screws for metal siding on a rectangular wall based on the dimensions.
- Corrugated Metal Paint or Coating Volume: This estimates the volume of paint or other coating (e.g., spray insulation) is needed for a corrugated surface.
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
