Metal Screws for Gable Roof

Processing...

The Metal Screws for Gable Roof calculator computes the number of special screws needed for a metal roof. Metal roofs are typically connected to purlins or sub-boards using special screws that self-start through the metal and have a rubber collar to seal out water.

INSTRUCTIONS: Choose units and enter the following:

(L) Ridge Length of Roof
(S) Span of Roof
(oH) Overhang
(P) Pitch of Roof

Screws for a Metal Roof (SK): The calculator returns the number of screws needed for a metal roof. The calculator also returns the Surface Area of the Roof.

The Math / Science

The Screws for a Metal Roof calculator computes the area of the roof based on the ridge length, span, overhang and pitch. It then calculates the number of screws needed based on 75 screws per 100 ft²of roof.

Gable Roof Calculators

Gable Roof Area: This computes the surface area of a gable roof based on dimensions and pitch.
Trusses Needed for Roof: This computes the number trusses need for a roof including gabled roof.
4x8 Sheathing for Gable Roof: This computes the total surface area of a roof, the number of 4x8s and framing nails needed for a gabled roof based on the length, span, pitch and overhang.
Gable Roof Sheathing Cost: This computes the number of 4x8 sheets (32 ft² each) needed to cover a gabled roof based on the ridge length, roof span, overhang and the pitch and applies the unit cost of a 4x8.
Nails for Gable Roof Sheathing: This computes the approximate number of nails needed to nail 4x8 sheets to trusses or rafters on a roof based on the dimensions of the roof, spacing of nails on the edges and field of the 4x8, and whether blocking or clips are use.
Purlins for Gable 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.
Metal for Gable Roof: This estimates the metal panels and trim needed for a metal roof for a simple gabled roof based on the roof dimensions.
Metal Screws for Gable Roof: This computes the number of special screws needed for a metal roof.
Shingles for Gable Roof: This computes the number of shingles (bundles), underlayment, ridge shingles, starter strip, and roofing nails for a gable roof.
Gable Roof Shingle Cost: This estimates to shingle a basic gable roof based on dimensions (length, span, pitch and overhang) and the unit price of a bundle of shingles.
Underlayment for Gable Roof: This estimates the cost of underlayment to cover a basic gable roof based on the area of a roof computed from the dimensions (length, span, pitch and overhang) and the unit price underlayment material.
Roofing Nails for Gable Roof: This estimates the number of roofing nails needed for a common gabled roof based on roof dimensions and wind conditions.
Rafters for Gable Roof: This computes the total number of rafter boards (roof joists) for a gabled roof based on the ridge length, pitch and span. It also returns the length of the ridge board, and the length and number of rafter ties and collar ties.
Rafter Length: This computes the length of the rafters based on the span, pitch and overhang.
Gable Roof Geometries: This computes the length of rafters, pitch and cut angles, soffit and facia base widths of a gable roof.
Weight of Snow on Roof: This computes the weight of snow on a gable roof based on roof dimensions, depth and type of snow.

Metal Panel Screws are a specialized product that include a gasket to seal around the screw head and prevent moisture from penetrating the roof or siding through the screw hole, and a screw tip that cuts through the metal panels and is self-starting. Metal panel screws often come in painted colors to match the metal panels. The screws are used to attach metal panels to purlins or sheathing for a metal roof or to girts or sheathing for metal siding. Metal Panel Screws are typically used with a density of 75 screws per 100 square feet of metal roofing or siding area.

Metal Panel Screw Information

75 screws per 100 ft² of roof surface area is the industry standard for screws in a metal roof.
