To install Palruf roofing, you need to prepare your roof surface, lay down underlayment, and then secure the corrugated panels with fasteners and sealant. Palruf is a lightweight plastic roofing material that works well for sheds, garages, and covered areas. The installation is easier than many other roof types because the panels are simple to cut and attach. Most homeowners can install Palruf in one to two days with basic tools. According to RubyHome, corrugated metal roofing installation costs between $5.50 and $11.50 per square foot, and Palruf falls in that affordable range. This guide shows you the exact steps to get the job done right.

What You Need Before Starting

Gather all your tools and materials first. You will need a measuring tape, circular saw or utility knife, work gloves, safety glasses, a hammer or drill, roofing nails or screws, roofing sealant, underlayment, and a ladder.

Check your roof surface for damage, holes, or rotted wood. Fix any soft spots or broken areas before you start. A clean, flat surface is key to a successful installation.

Step One: Prepare Your Roof Surface

Clean the roof completely. Remove dirt, leaves, and old roofing material. Sweep everything away so you have a bare, clean surface to work on.

Inspect the roof structure for weak spots. Press on wood with a screwdriver to check for soft, rotted areas. Replace or repair any damaged wood before laying Palruf panels. This prevents leaks later.

Step Two: Install Underlayment

Underlayment is a protective layer that goes under your Palruf panels. Roll it out across the roof surface. Use roofing nails or staples to secure it every 12 inches along the edges and center seams. Overlap each section by at least 6 inches.

Underlayment adds extra protection against water damage and improves roof lifespan. According to industry data, proper underlayment installation helps extend roof durability by preventing moisture buildup under panels.

Step Three: Lay and Secure Palruf Panels

Start at the lowest point of your roof. Position the first Palruf panel with the flange side down. Make sure it overhangs the edge by at least 2 inches to direct water away from your walls.

Use roofing screws or nails at the high points of the corrugated ridges only. Do not nail the valleys. Space fasteners 12 inches apart along each ridge line. Over-nailing causes leaks and panel damage. Seal each fastener hole with roofing sealant.

Overlap panels by one full corrugation width. Use roofing sealant under each overlapped section. This keeps water from getting between panels and prevents leaks.

Palruf Installation Task	Time Needed
Surface prep and cleanup	2-3 hours
Underlayment install	2-4 hours
Panel layout and fastening	3-6 hours
Sealing and final touches	1-2 hours

Finishing Your Palruf Roof

Add flashing around pipes, vents, and roof edges. Flashing directs water away from holes and seams. Seal all flashing with roofing caulk.

Palruf roofs typically last 20 to 30 years with proper care. According to RubyHome data, plastic composite roofing can last 40 to 50 years, so Palruf sits on the lower end but remains durable for sheds and temporary structures. Clean gutters twice yearly and remove debris to extend lifespan. Check the roof yearly for loose fasteners or damaged panels.
