To lay corrugated roofing, you need to prepare the roof deck, install underlayment, secure the corrugated panels with fasteners, and seal all seams and edges. Corrugated metal roofing is a popular choice for many homeowners and businesses. According to RubyHome (2025), corrugated metal roofing costs between $5.50 and $11.50 per square foot for installation. This makes it an affordable option compared to other materials. Metal roofing can last 40 to 80 years, which means you get great value for your money. Let’s walk through the steps to install it the right way.
What Do You Need to Prepare First?
Start by checking your roof deck. Make sure it is clean, dry, and flat. Remove any old roofing material, nails, and debris. If there are soft spots or holes, repair them before you begin.
Next, install underlayment over the entire deck. Underlayment is a protective layer that stops water from seeping through. Secure it with nails or staples every 6 inches along the edges. Overlap each row by 4 to 6 inches.

How Do You Install the Corrugated Panels?
Start at the bottom of your roof and work your way up. Lay the first panel along the edge. Use corrugated roofing fasteners, which are special screws with rubber washers.
Drive fasteners through the high points of the corrugation into the wood deck below. Space fasteners 12 inches apart along each support beam. Do not over-tighten fasteners, as this can crack the panels. According to industry data, proper fastening prevents wind damage and extends roof lifespan. Overlap each new panel by one corrugation (or 2 inches) with the panel next to it. This overlap stops wind and rain from getting underneath.
What About Sealing and Finishing?
Seal all seams with corrugated roofing sealant or flexible caulk.
Install ridge caps along the peak of your roof. Ridge caps cover the gap at the top and keep water out. Use the same fastening method as the panels. According to RubyHome (2025), corrugated metal roofing installation cost ranges from $4 to $40 per square foot, depending on the quality and local labor rates. Add flashing around vents, skylights, and chimney areas. Flashing is metal trim that directs water away from openings.
