To install metal roofing on a house, you need to prepare the roof base, add underlayment, and secure the metal panels with proper fasteners. Metal roofing is a smart choice because it lasts much longer than asphalt shingles. According to industry data, metal roofing can last 40 to 80 years, while asphalt shingles only last 20 to 30 years. The installation process takes planning, the right tools, and careful work. Many homeowners hire professionals, but understanding the steps helps you know what to expect. Metal roofs cost between $10 and $17 per square foot for standing seam panels, which is more upfront but saves money over time.

Step 1: Prepare Your Roof Base

Start by removing old shingles and any debris from your roof. Make sure the roof deck is clean and dry before you begin. Check for soft or damaged wood and replace it.

Your roof base must be solid and flat. Measure your roof carefully to know how many metal panels you need.

Step 2: Add Underlayment and Flashing

Underlayment goes under the metal panels to stop water leaks. Roll out the underlayment across your entire roof from bottom to top. Nail it down with roofing nails spaced every 12 inches.

Flashing is metal trim that seals edges, valleys, and areas around chimneys. Install flashing before you add the metal panels. This keeps water from running under your roof.

Step 3: Attach Metal Panels

Start at the bottom of the roof and work your way up. Line up the first panel straight and nail it down. According to RubyHome, roof installation costs range from $4 to $40 per square foot depending on the material type. Use metal roofing fasteners with rubber washers to prevent leaks.

Overlap each new panel over the previous one by 1.5 inches. This lets water drain down without pooling. Use a screw gun or drill to attach fasteners every 12 to 16 inches along the seams.

Why Choose Metal Roofing?

Metal roofs are fire resistant, lightweight, and energy efficient. According to the Insurance Information Institute, hail damage cost U.S. homeowners $160 billion in reconstruction cost value in 2024, and metal roofing resists hail better than asphalt.

According to RubyHome, the average roof replacement cost is $9,526, with a range of $5,868 to $13,217. Metal roofing costs more upfront but delivers an ROI of up to 110% at home resale according to the NAR Remodeling Impact Report 2025. According to This Old House, 31% of homeowners pursued roof renovation or repair in the last 3 years, and 79% hired contractors to do the work. Proper installation is key to getting the full lifespan from your metal roof.
