Homeowners who would never consider roofing their homes often entertain the idea of roofing their backyard shed or workshop. And for good reason: Shed roofs are far smaller and more manageable, and they tend to be much closer to the ground than house roofs. Learn about the best shed roofing materials for this satisfying DIY project.

  Roll Roofing Corrugated Sheets Composite Shingles Galvanized Panels

Pros Fast installation Easy to install Matches look of most houses Look like standing-seam roofing
Cons Difficult to waterproof May come off in winds Slower to install Pricier than corrugated panels
Installation Roofing is rolled out and nailed down in overlapping fashion Sheets are nailed down lengthwise (facing down) and overlapping Each shingle nailed individually and overlapped by shingle in upper row Sheets nailed lengthwise with galvanized nails

Roll Roofing

Pros
  • Very inexpensive

  • Easy to install

  • Quickly covers large spaces

  • Easy to transport materials

Cons
  • Less attractive than other roofing materials

  • Thin

  • Needs frequent replacement or repair

Roll roofing, also called mineral-surfaced roll or MSR, has a similar makeup to conventional asphalt shingles but it comes in wide rolls.

Roll roofing is thinner, less expensive, and easier to install than shingles. Roll roofing can be installed with nails, as long as the roof has some pitch (slope) to it. For flat roofs, it is usually installed using a torch-down method.

A standard roll of roll roofing is 36 inches wide and covers 100 square feet, an area that roofers refer to as a square. In most cases, one or two rolls should be sufficient to cover the average shed or workshop.

Torch-Down

Torch-down is the process of applying roofing materials by melting adhesive materials with an open-flame torch. The flame heats up the adhesives until they become soft, thus joining the roofing materials.

Roofing With MSR Roll Materials

In most cases, MSR roll roofing is the cheapest shed roof material you can buy. Roll roofing is also the easiest shed roof to install because you can cover large areas quickly by simply rolling it out and nailing it down.

Rolled roofing is not considered to be very attractive and will do nothing to raise your property's resale value. Roll roofing is thin, so five years is a comfortable life expectancy of roll roofing before it needs to be replaced.

MSR Roofing Cost

The roofing material itself costs about $0.50 to $1 per square foot, making it economical to install. The cost of the fasteners for roll roofing is about $6 per 400-count of large-head, corrosion-resistant roofing nails,11-gauge.

Corrugated Roofing

Pros
  • Covers large spaces

  • Reasonably attractive

  • Waterproof

Cons
  • Large sheets difficult to transport with a truck

  • May rip off in high winds

  • Homeowner covenants may not allow this type of material

Corrugated roofing panels come in three common materials: metal (galvanized steel or aluminum), fiberglass, or polycarbonate plastic. The metal version is the classic roofing often referred to as a tin roof.

Corrugated roofing panels are 8 feet long and about 2 feet wide and install very quickly. Their edges overlap at the seams to keep out water, and the panels are installed with special nails or screws that have neoprene gaskets or washers to create a watertight seal.

Corrugated steel panels are not the same as standing seam metal roofing. Standing seam is more expensive roofing with sealed edges that are only installed by qualified roofers, not by homeowners.

Corrugated Roofing Cost

Corrugated roofing costs about $1 per square foot, based on galvanized steel 8-foot panels that 25-3/4-inch wide. The cost of the fasteners is about $15 per 250-count for #9 Galvalume wood fasteners with built-in washers.

Roofing With Corrugated Materials

With some corrugated steel products, entire roofing systems are available that include closure caps, valleys, ridge caps, hip caps, and other accessories used in roofing a home.

Corrugated roofing can rip off in high winds. Corrugated roofing in good condition looks reasonably attractive. But rusted metal corrugated roofing is an eyesore. Homeowner's associations may prohibit the use of corrugated metal roofing.

Composite (Asphalt) Shingles

Pros
  • Inexpensive

  • Attractive

  • Can match house roofing, if desired

Cons
  • Installation takes some know-how

  • Premium shingles are expensive

  • Longer installation time

Standard asphalt three-tab shingles represent a compromise between the utilitarian (galvanized steel or rolled asphalt) and the gorgeous (cedar shake shingle). 

You can buy asphalt shingles at your local home center in a limited range of colors. For a shed, a standard-grade shingle is sufficient, unless you want the look of a thicker, premium-grade material.

Roofing With Composite Shingles

Composite shingles mean that you can install a shed roof that matches, or comes reasonably close to, the color and look of your home's roof. Shingles tend to give your shed a better look since they look less shed-like and more like a house.

Installing three-tab shingles is a bit more involved than corrugated and roll roofing. Each shingle must be installed individually and in the correct order. Composite shingles will not be waterproof on very low or no-slope roofs.

Composite Shingle Cost

Composite shingles cost about $1 per square foot for standard-grade 3-tab shingles. The fasteners cost about $25 per 1,000-count of roofing nails.

Galvanized Metal Roof Panels

Pros
  • More attractive than corrugated panels

  • Durable

  • Fireproof

Cons
  • More expensive than corrugated roofing

  • Not true standing-seam roofing

  • Wind may pull it off

Galvanized metal roofing panels emulate the look of standing-seam metal roofing. Every 6 to 8 inches, there is a 3/4-inch high rib and the rest of the panel is flat.

The rib is all for show. Galvanized metal roofing panels are installed just like their corrugated panel counterparts. But the standing-seam simulation helps the panels avoid much of the eyesore factor of corrugated panels.

Panels 8 feet long and 3 feet wide cost in the range of $38 to $42 each: about 25-percent more than corrugated panels.
