Based on building codes, a 2×6 can span anywhere from 2'-1” to 20'-8” depending on the affecting factors. Ceiling joists don't normally have the same load restrictions, and so can span greater distances.”
A 2x6 floor joist can typically span up to 12 feet and 6 inches without support. However, the distance a joist can span depends on several factors, including the spacing of the joists and the type of wood used: Spacing: For example, a 2x6 redwood or cedar joist can span eight feet if spaced 16 inches apart.
The most common lumber sizes for floor joists are 2x6, 2x8, 2x10, and 2x12. Larger joists can span across wider areas. For example, a 2x6 joist would have a 12-foot, 6-inch maximum span, and a 2x10 joist would have a 21-foot maximum span.
A 2x6 can typically span up to 10 to 12 feet for a metal roof, depending on the load requirements and local building codes.
Common rafters lean at a 30° angle against a wall, allowing for a maximum span of 2.5 meters. Used to cover a building's verandah, lean-to roofs rely on a supporting wall or another roof for stability.
“A general rule of thumb for joist span is 1-1/2 times a board's depth in feet, however, it's not that simple. The distance a 2×6 can span is determined by the species, grade, location, use, load, and spacing. Based on building codes, a 2×6 can span anywhere from 2'-1” to 20'-8” depending on the affecting factors.
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.

Should be nothing less than 2x6 16 on center. If you go to 2x4 purlins you could probably go to 24 on center for the rafters.
Typically, a 2x6 deck board can support around 50 pounds per square foot (psf) when spanning 16 inches on center (OC). However, as the span decreases, the weight capacity per square foot increases. For example, if the span is reduced to 12 inches OC, the load capacity can increase to around 75 psf.
A 2x6 floor joist can typically span up to 12 feet and 6 inches without support. However, the distance a joist can span depends on several factors, including the spacing of the joists and the type of wood used: Spacing: For example, a 2x6 redwood or cedar joist can span eight feet if spaced 16 inches apart.

2x8: They're often used for mid-range floors, such as those in living rooms or dining rooms. They can span up to 10 feet and have a higher load-bearing capacity than 2x6 joists.

PVC Plastic Sheets

To make up for this, a lot of plastic roof sheets are corrugated and as such are unlikely to sag between the frame of your Lean-to.
Generally, lean-to roofs have a pitch that ranges from 1:12 to 4:12, with a 1:12 pitch being the shallowest and a 4:12 pitch being the steepest. A shallower pitch of 1:12 or 2:12 is often used for lean-to roofs primarily designed to provide shade or shelter from the rain.
Slate is the most expensive roof material available. Its high cost is due to its durability and aesthetic appeal. This article explains why slate is costly, its benefits, and if it's worth investing in for your home.
