Roof Sq Ft Calculator – Easy Roofing Measurement

This tool will calculate the total square footage of your roof based on your inputs.

Roof Square Footage Calculator

How to Use

Enter the length and width of the roof in feet, as well as the slope of the roof in degrees. Click “Calculate” to receive the total square footage.

Explanation

This calculator estimates the square footage of a pitched roof. It considers the length, width, and slope of the roof. The slope is the angle of the roof relative to a flat surface. The calculation uses these steps:

  1. Calculate the area of the base by multiplying length and width.
  2. Adjust for the slope using the cosine of the slope angle.

The formula is: Area = (Length * Width) / cos(Slope in radians)

Limitations

This calculator assumes a single, simple slope for the roof. Complex shapes and multiple slopes are not considered. For more accurate measurements on complex roofs, a professional assessment is recommended.

Use Cases for This Calculator

Calculate Square Footage of a Flat Roof

Enter the length and width of your flat roof, and the calculator will give you the total square footage. This is useful for determining materials needed for a flat roof replacement or repair project.

Determine Square Footage of a Gable Roof

If you have a gable roof, simply input the length and width of each section, and the calculator will provide the total square footage. This helps in estimating the cost of shingles or metal panels for your gable roof.

Estimate Square Footage of a Hip Roof

For a hip roof, input the dimensions of each hip section, and the calculator will give you the total square footage. This is essential for budgeting roofing materials for a hip roof construction or renovation project.

Compute Square Footage of a Mansard Roof

If you have a mansard roof, input the measurements of the lower and upper roof sections to get the total square footage. This aids in planning for materials like slate or tiles required for a mansard roof makeover.

Calculate Square Footage of a Gambrel Roof

For a gambrel roof, enter the dimensions of the upper and lower roof sections to find the total square footage. This allows you to estimate the quantity of asphalt or cedar shakes needed for your gambrel roof renovation.

Find Square Footage of a Saltbox Roof

If you have a saltbox roof, input the length and width of the roof sections, and the calculator will determine the square footage. This information helps in budgeting for materials like wood shakes or composite shingles for your saltbox roof project.

Estimate Total Square Footage of a Butterfly Roof

Calculate the square footage of both roof sections of a butterfly roof by providing their dimensions. This assists in planning for roofing materials like polycarbonate panels or green roofing systems for a butterfly roof construction.

Determine Square Footage of a Shed Roof

Enter the length and width of your shed roof to find out its square footage. This is helpful in deciding the amount of corrugated metal or EPDM membrane needed for a shed roof replacement or construction.

Compute Square Footage of a Pyramid Roof

If you have a pyramid roof, input the dimensions of its base to calculate the total square footage. This is essential for ordering materials like clay tiles or standing seam metal for a pyramid roof renovation.

Calculate Irregular Roof Square Footage

For roofs with irregular shapes, enter the measurements of distinct sections to determine the total square footage. This feature is beneficial for accurately estimating materials required for renovating or constructing roofs with complex designs.
