To lay corrugated roofing sheets, you need to prepare your roof frame, install underlayment, secure the sheets with fasteners, and seal all joints. Corrugated metal roofing is popular because it is strong and lasts a long time. According to RubyHome, metal roofing can last 40 to 80 years, making it one of the best choices for durability. These sheets are lightweight, easy to work with, and cost between $5.50 and $11.50 per square foot when installed. Let’s walk through the steps to lay them correctly.
Step 1: Get Your Materials Ready
Before you start, gather all your tools and materials. You will need corrugated metal sheets, fasteners, underlayment, a drill, a saw, and safety gear.
Make sure your roof frame is clean and dry. Remove old shingles or debris. According to RubyHome, corrugated metal roofing installation costs range from $4 to $40 per square foot depending on quality and labor. For a 1,700 square foot roof, expect to spend between $6,800 and $68,000 total. Having the right prep work saves time and money later.

Step 2: Install Underlayment
Underlayment is a protective layer that goes under your metal sheets. It stops water from leaking into your home. Unroll the underlayment across your roof from bottom to top. Use staples or nails to secure it every 12 inches.
Overlap each row by at least 6 inches. This overlap keeps water from running under the material. Make sure the underlayment is tight and smooth before adding your metal sheets.
Step 3: Lay Your Corrugated Sheets
Start at the bottom of your roof and work your way up. Position the first sheet so it hangs 1 to 2 inches over the roof edge. This overhang guides water away from your walls.
Lay the second sheet so it overlaps the first by one wave or ridge. Overlap is key to keeping water out. Use corrugated fasteners or self-tapping screws to secure each sheet. Space fasteners 12 inches apart in rows. According to industry data, proper fastening prevents wind damage and leaks during storms.
Step 4: Seal and Finish
Use roofing sealant along all joints and seams. This stops water from entering at connection points. Pay special attention to ridges, valleys, and roof edges.
Add ridge caps at the top for extra protection. Install flashing around any chimneys or vents. Metal roofing can last 40 to 80 years according to RubyHome, but only if sealed properly. Let all sealant dry for 24 hours before any rain.
