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.
