The **Screws for a Metal 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 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 ft^{2 }of roof.

**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.

- 75 screws per 100 ft
^{2}of roof surface area is the industry standard for screws in a metal roof. - Common Screw Packaging Sizes: 1lb, 5lb, 20lb, 25lb, 30lb
- Common Metal Panel Screw Weights and Density
- #10 x 1" - 115 per pound
- #10 x 1
^{1}/_{2}" - 95 per pound - #10 x 2" - 75 per pound
- #10 x 21/2" - 65 per pound

- Total Building Materials Calculator
- Roofing Calculators
- Metal for a Roof - Calculates the number of metal panels for a roof.
- Area of a Roof - Computes the area of a roof based on the pitch and the dimensions of the area covered by the roof. It also returns the number of 4x8 sheets to cover the roof, the number of standard bundles of shingles to cover, and the number of roofing nails for both normal and high wind environments.
- Pitch of a Roof - Computes angle of incline in the roof in both degrees and rise over 12" run (e.g. 26.6
^{o}: 6/12) based on the length of the rise and run. - Number of Trusses Needed for a Roof - number of trusses needed based on the roof width and the truss spacing.
- 4x8s needed for a roof - Calculates the number of 4x8 sheets needed to cover a roof.
- Shingles needed for a roof - Calculates the number of standard bundles (33.3 ft
^{2}) of shingles for a roof. - Roofing nails needed for a roof - Calculates the number of roofing nails needed for a roof in normal and high wind conditions.
- Number and Length of Metal Roof Panels - Computes the length and number of metal panels and trim pieces for a metal roof.
- Screws for a Metal Roof - Computes the number of screws needed for a metal roof.
- Number and Length of Purlins for a Roof - Computes the number of purlins for a roof based on dimensions and spacing.
- Number and Length of Rafters - Computes the number and length of rafter boards based on roof dimensions and spacing.
- Number and Length of Rafter and Collar ties - Computes the number and length of rafter ties and collar ties based on roof dimensions and spacing.
