`"Metal Roof" = "Gable Roof Metal"`

Enter a value for all fields

The **Metal for a Gable Roof** calculator estimates the materials needed for a metal roof for a simple gabled roof based on the roof dimensions.

**INSTRUCTIONS:** Choose units and enter the following:

- (
**L**) Ridge Length - (
**S**) Roof Span - (
**P**) Roof Pitch - (
**oH**) Overhang - (
**R**) Rake of Roof Overhang - (
**PD**) PANELS or DETAILS

**Metal for a Roof (RM):** The calculator returns the number and length of panels. If "DETAILS" are chosen, the calculator returns the following:

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

The Metal for a Roof calculator is meant to help with material estimates for a metal roof. In all cases, confirm your estimates with a professional estimate and adhering to local building codes.

The calculator uses the ridge length, pitch and roof span to compute the roof area. The most common width of both G-Rib and R-Rib metal panels is 36". This is the default in this calculator. Note: under the ridge cap, you will need **foam closure** which keeps rain from being driven up under the ridge cap. The length of the foam closure that you'll need is four times the ridge length, two for either side of the ridge, and two for the bottoms above the angle trim.

A spacing of twenty four inches (24") between rows of purlins is used to compute the number and length of purlins. To compute the length and number of purlins using a different spacing, use the Purlins for a Roof Calculator (CLICK HERE).

The Pole Barn Calculator contains functions to compute the construction materials for a pole barn with concrete piers, a slab, wood framing, roof trusses for a normal gabled roof and metal panels and trim for the roof and siding.

**Gable Roof Metal**: This estimates the materials needed for a metal roof for a simple gabled roof based on the roof dimensions.**Purlins for a Roof**: This computes the total number and length of purlins for a simple gable roof based on the ridge length of the roof, the roof pitch and the span of the roof.**Trusses Needed for Roof**: This computes the number of trusses needed for a roof based on the ridge length and spacing.**Metal Siding for Gable Ends**: This computes the metal siding materials (vertical panels) for a wall under a gable roof end based on the dimensions.**Metal Siding for Gable End with Door**: This computes the metal siding materials for a wall under a gable roof end based on the dimensions.**Girts for a Building**: This computes the number of rows of girts and their lengths for a building.**Wall Beams for a Building**: This computes the lengths beams for the outer wall of a building.**Posts for a Building:**This computes the number of vertical posts for a building based on dimensions and spacing.**Rebar and Concrete in a Slab**: This computes the total length and weight of rebar and the volume of concrete needed for a slab.**Piers for a Building**: This computes the number of piers for a building and the amount of concrete needed.**Pole Barn Materials**: This computes the top to bottom framing and roofing materials needed for a pole barn (see picture) based on a few dimension.

**IMPORTANT NOTE**: **Confirm all calculations with authoritative sources** such as architectural drawings before risking health or wealth on the results of any calculator, and **ALWAYS adhere to government approved building codes**.
