How much metal roofing do I need for a 12×20 shed?

A 12×20 shed with a 4:12 pitch and 36-inch wide panels needs approximately 160–180 linear feet of panel (both slopes). Use our calculator at /calculator for a precise estimate based on your pitch and dimensions.

Can I install metal roofing on a shed myself?

Yes. Through-fastened metal roofing (9-5 Panel or corrugated) is a feasible DIY project. You need panels, ridge cap, eave trim, metal-to-wood screws, closure strips, and sealant. Instructions are available from panel manufacturers.

What is the minimum order at FL Sheet Metal?

Metal Roofing for Sheds and Workshops in Florida

What Is the Best Metal Roofing for a Florida Backyard Shed or Workshop?

Backyard sheds, workshops, garages, and outbuildings are a perfect application for affordable metal roofing panels. Metal outlasts wood shake and asphalt shingles significantly in Florida's sun and rain, requires no maintenance, and is available from FL Sheet Metal with no minimum order — perfect for DIY homeowners and small contractors.

For shed and workshop roofing in Florida, 29-gauge 9-5 Panel in Galvalume is the most popular choice. At $4.00/ft, it's the most affordable metal panel we carry, and it provides decades of maintenance-free performance on structures that don't require the full structural capacity of 26-gauge panels. A small 12×16 storage shed (2 slopes of approximately 100 sq ft each) uses roughly 140–160 linear feet of 9-5 Panel panel — a project that can be completed for $525–$600 in panel material.

For workshops and garages that need a more finished appearance, 29-gauge colored 9-5 Panel in Polar White, Charcoal Grey, or Barn Red provides a clean aesthetic at minimal additional cost over Galvalume ($6.50/ft colored vs. $4.00/ft Galvalume). Color-matching ridge caps and eave trim complete the professional look.

Corrugated metal panels ($6.00/ft, 2-ft wide, up to 14 ft long) are an excellent option for small sheds and outbuildings where the traditional corrugated aesthetic is desired. Their 14-ft maximum length covers most small-structure applications, and Galvalume's bare-metal look is well-suited to agricultural and industrial building aesthetics.

For DIY shed re-roofing projects, the installation materials are simple: panels, ridge cap, eave trim, wood-to-metal hex screws, closure strips, and sealant. FL Sheet Metal sells all accessories individually with no minimum order — you can buy exactly what you need for your project.
