To bid a metal roofing job, you need to measure the roof size, pick your materials, add labor costs, and include your profit margin. Metal roofing is one of the fastest-growing roofing types in the U.S. because it lasts so long and saves energy. According to the Metal Roofing Alliance, metal roofing holds 17% market share in residential roofing. A good bid protects your profit and keeps customers happy. Let’s walk through the steps to bid metal roofing the right way.
What Size Is the Roof?
Start by measuring the roof square footage. One square equals 100 square feet. According to the National Association of Home Builders, the average U.S. roof size is 2,647 square feet or 26.47 squares.
Measure twice. Use a tape measure or climb the roof if safe. Take photos and note the pitch. A steep roof takes more time to install.

Calculate total labor hours. Metal roofing takes about 4 to 8 hours per square. Multiply hours by your hourly rate plus taxes and insurance.
What Are Material Costs for Metal?
Metal roofing costs vary by type. Standing seam metal panels range from $10.00 to $17.05 per square foot. Corrugated metal costs $5.50 to $11.50 per square foot. For a 1,700 square foot roof, your material cost ranges from $6,800 to $68,000 depending on the metal type you choose.
Buy materials directly from suppliers when possible.
