The most common slopes are.
Good slope fro shed roof.
Metal roof slope is expressed by a ratio indicating the roof pitch which notes the vertical rise of the roof in inches for every 12 inches the roof runs horizontally in other words dividing the vertical rise and its horizontal span.
Whereas a hip roof and other popular roof types have at least two sides the shed roof has a single slope that can vary in steepness depending on the design.
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.
Think of a shed roof as a flat roof at a steeper slope.
Felt shingle systems can achieve lower slopes down to about 20 degrees.
Remember metal roofing is more expensive than shingles.
Beyond that you re free to choose whatever slope best fits your plans for your shed.
Roof pitch for the shed roof pictured above the back has a 5 12 pitch.
A roof with a slope of 10 degrees 2 12 or less is generally considered a flat roof.
Basically the steeper the pitch the better it can shed snow and rain.
For slopes below 20 degrees systems such as epdm fibreglass metal roofing can be used.
The roof is typically sloped down from the connecting wall if the shed is attached to the side of your house or garage.

Acceptable flat roof coverings include tin roof sheets and pre fabricated plastic sheets.

There are advantages and disadvantages to having a steep pitch versus a shallow or low pitch the most obvious of which is the roof s ability to shed or withstand heavy snow rain or wind.
When looking at metal roofing panel you will need to.
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.
If you have to go with a roof pitch less than 3 12 then it would either have to be a metal roof or a roof covered with a rubber membrane to prevent water penetration.
The flip side to this is that it also becomes more expensive to build both in materials and logistical difficulty.
Because these roofs shed snow ice and rain more easily they tend to last longer than low pitch roofs.
You can also think of it as one half of a traditional gable roof.
Heavier materials such as slate and clay tiles need a larger.
These roofs require you to have special equipment to walk on them safely.
