To install pro rib metal roofing, you need to prepare the roof deck, add underlayment, snap chalk lines, and screw the panels down with proper fasteners. Metal roofing is growing fast because it lasts 40 to 80 years and resists weather damage well. According to industry data, metal roofing now holds a 17% market share in residential roofing, up from just 10% a few years ago. This guide shows you the steps to do it right.

What Do You Need Before Starting?

First, gather your materials and tools. You will need pro rib metal panels, fasteners made for metal roofs, an underlayment, a drill or screw gun, and a tape measure.

Check your roof deck for rot or soft spots. Replace any bad wood before you start. Your roof must be dry and clean. According to the U.S. Bureau of Labor Statistics, the median hourly wage for roofers is $24.05, which shows this is skilled work that takes time and care.

How Do You Prep the Roof Deck?

Remove old roofing material if needed. Sweep the deck clean. Check that all nails are flush or removed.

Add a water shield underlayment across the whole roof. Start at the bottom and work up. Each row should overlap the row below by 6 inches. Nail or staple the underlayment every 12 inches. This stops water from getting under your panels.

What Are the Steps to Install the Panels?

Snap chalk lines on your underlayment every 24 inches. These lines help you keep panels straight. Start at one end of the roof.

Place your first pro rib panel at the bottom edge. Use three fasteners per rib at the overlap zone. Then slide the next panel into place and fasten it. Keep going until you reach the top. According to RubyHome, metal roofing installation costs range from $4 to $40 per square foot, so quality installation matters for your investment.

Seal all fasteners with a waterproof sealant. This keeps rain out of screw holes.
