How much should a shed roof overhang?
Larger overhangs can help to keep you dry while standing at the shed’s doorway and prevent the sun from heating your shed.

Can I use 4×2 for flat roof?
2×4 rafters are not strong enough for low pitched roofs under any circumstance, so avoid if you are building a shed with a flat or very shallow roof.
How do you slope a flat roof for drainage?
For drainage purposes, the current building codes require a minimum two percent slope or a one-fourth unit vertical for every 12 units horizontal. In other words, the roof must slope one-fourth of an inch for every 12 inches. The slope is barely noticeable to the naked eye.
What kind of plywood do you use for a shed roof?
Most builders use 15/32 CDX for the roof; it is an exterior-grade plywood with a thickness just under 1/2 inch. The floor needs to be more solid than the roof to support lawn maintenance equipment and people. Use sturdy, 3/4-inch-thick exterior plywood for the floor.
What is the minimum slope for water flow?
For efficient drainage, paved surfaces should have a minimum 1-percent slope. Turf or landscaped areas should have a minimum slope of 2 percent.
What kind of roof do I need for a 2 12 pitch?
A pitch of 2/12 is the minimum for shingles made of asphalt, so your roof just barely makes the cut-off for one of the most popular roofing material options. Resilient asphalt shingles lie much flatter to the substrate than slate, tile and concrete, which keeps water from being easily blown under them.
What is the easiest roof to build?
This article will discuss a gable roof, without valleys or dormers, because it’s the most common and the easiest for a first-time builder to tackle. After you determine the rise, span, run, line length and pitch, the next step is to lay out the rafters, or mark the cuts on a pattern rafter to create the roof.

How do you insulate a single slope roof?
Spray a layer of closed-cell polyurethane foam on top of the roof sheathing, supplemented by a layer of air-permeable insulation below and in direct contact with the roof sheathing. Spray a thick layer of closed-cell polyurethane foam on the underside of the roof sheathing.
Are shed roof houses cheaper to build?
Yes, shed roofs are cost-effective options because of their simplicity. A basic roofing design with only one slope is easier and less time-consuming to work on for contractors, and this translates into lower roofing construction costs. In the past, people used shed roofs exclusively for their garden sheds and garages.
Does a shed roof need rafter ties?
Rafter ties are always required unless the roof has a structural (self-supporting) ridge, or is built using engineered trusses. A lack of rafter ties is a serious structural issue in a conventionally framed roof. In most homes, the ceiling joists also serve as the rafter ties.
What size lumber are roof rafters?
Max. Live Load 20 lbs/ft2 (956 N/m2) Maximum Span (ft – in) Nominal Size (inches) Rafter Spacing, Center to Center, OC (inches) Lumber Grade 2 x 6 12 16′ – 4” 16 14′ – 11” 24 13′.
What is the distance between rafters on a roof?
But they do tend to space rafters in one of several industry-standard increments, typically either 12, 16 or 24 inches apart. These spacing intervals are measured “on center,” meaning that the measurement is taken from the center of one rafter’s horizontal surface to the center of the next rafter.
