Low Slope Shed Roof

Sheds rain and snow quickly.

Low slope shed roof.

However if you choose to build a freestanding shed and use this style of roof you should plan the slope of your roof in such a manner as to slope down from the front to the back of the shed. For a low slope residential roof there are two main options. Fast run off of rain or snow can cause ground erosion behind the shed. A quarter inch slope is the lowest you would go with a metal roof experts recommend at least a half inch minimum to ensure a weatherproof interior for your shed.

The roof is typically sloped down from the connecting wall if the shed is attached to the side of your house or garage. Remember metal roofing is more expensive than shingles. Having a steeper pitched roof allows for more space in a shed loft. Expensive to convert a mono pitched roof to a multi slope roof since all walls need to become the same height.

Some builders even choose to match it directly especially if the shed s roof is attached to the house on the high side and just one simple span pitch. Low slope shed roofs that range in pitch from nearly flat to 4 over 12 are common in the southwest and in dense urban neighborhoods of the northeast. 1 cover the entire surface with a self adhesive flashing membrane such as grace ice water shield there are many. Snow may also build up more on a shed roof with a low slope.

This image shows a relatively shallow roof pitch of 15 degrees. 2 where the roof is not visible consider upgrading to a single ply roofing intended for low slope roofs. These roofs are either framed with deep trusses or framed with rafters that are separate from the ceiling joists. A lower slope makes it more challenging for the water to run off the roof which may cause some pooling.

While most skillion roofs shed water well if yours has a very low slope you may notice some drainage issues. Another widely used method is to follow the house s roof pitch on one side building the ridge off center then sloping down more drastically on the shorter side which will be closer to the house. Asphalt shingles with certain application adjustments can generally be installed down to slopes of 2 12. Clear roof space without truss or rafters.

But for those lower slopes from 2 12 down to 1 2 12 you ll want a membrane system like roof fast.
