Our take on the 20-Pack Heavy Duty Corrugated Galvanized Steel Roofing Panels

A 20-pack of corrugated galvanized steel panels, each about 3.54 by 1.39 ft, giving roughly 98 sq ft of coverage. The zinc coating resists rust, and the corrugated profile sheds water and adds stiffness without framing. They suit small carports, sheds, lean-tos and garden structures where a light, low-cost metal cover is enough. Against painted steel or polycarbonate panels they are cheaper and tougher but thinner, so they dent and are not meant for walking on or for a full house roof.

Questions and answers

How much area do 20 panels cover?
Each panel is about 3.54 by 1.39 ft, roughly 4.9 sq ft. Twenty panels give about 98 sq ft before you allow for overlaps at the seams.
Can I use these on a house roof?
They are best for sheds, carports and outbuildings. The panels are thin and short, so a house roof needs longer, heavier-gauge panels and proper underlayment.
Do I need to overlap them?
Yes. Overlap one corrugation at the sides and several inches at the ends so water runs off rather than through. Plan for the overlap when you count panels.
What fasteners and trim do I need?
Use galvanized or coated screws with sealing washers driven into the crests, plus ridge caps and edge trim. None of these come in the pack.
Will the panels rust?
The galvanized zinc coating resists rust, but cut edges and scratched spots are vulnerable. Seal cuts and avoid contact with untreated steel or pressure-treated lumber.
