Using a metal roof calculator helps you determine panel quantities by dividing your roof's total square footage by the coverage area of each panel.
Metal roofing panels come in various sizes, so measuring your roof's length and width for each plane ensures you order the right amount of material.
Complex roof shapes like gambrel or hip roofs need careful measurement of each plane, including triangular sections calculated by multiplying base times height and dividing by two.
Hiring a local roofing professional takes the guesswork out of measurements and panel calculations, ensuring your metal roof project starts with accurate material estimates.

Calculating How Much Metal Roofing You Need

Based on the size of your roof, use the following formula to find out how many metal roofing panels you'll need:
Metal Roofing Panels Needed = Total Roof Area / Area of One Metal Roofing Panel
How to Measure Your Roof
Measuring your roof can be simple or more complicated, depending on whether the roof itself is simple or complex. You'll need to find out the length and width of each roof plane.
Measure the length and width of each plane, then multiply them together to get the square footage of the plane. Next, add together the square footage of each plane to get the total area of your roof.
For example, if your house has a simple gable roof, it has two roof planes. A gambrel roof has four planes. A hip roof also has four planes, but two of those planes are triangle-shaped. To calculate the area of a triangular plane, multiply the base of the triangle by its height, then divide by two.
Who to Hire to Install a Metal Roof
Roofing installation or repair isn't a DIY job. It pays to know who fixes roofs or replaces them entirely. Typically, a local professional roofer, one who's licensed and insured in your area, is the person to hire for the job.
A pro roofing contractor can measure the roof for you and calculate the number of metal panels your project requires. They'll also provide you with an estimate of the project's cost, so you can decide if installing metal panels is the right option for your home and budget.
