The basic construction of a flat roof starts with roofing timber that is laid across two upright items usually two walls.

A skillion roof is made up of a single flat plane which slopes gradually from top to bottom. Now that the walls are rigid from the structural sheathing we re going to tackle the framing the roof. One of the important decisions when building a shed is the foundation. Roofs with a pitch below 10 degrees are known as flat roofs.

From there the flat roof system you choose will determine the materials you apply. Do you want to build a shed that makes a perfect garden shed. The saltbox roof design offer lots of character and charm to the backyard. This will give additional stability to the roof structure.

I decided to use concrete deck blocks like i d used on my first shed. But flat roofs take a pounding from harsh weather which is why they rarely last as long as a good sloped roof. For a shed with this type of roof bitumen mineral felt on plywood decking or sheet metal will be the main options. Flat roofs have experienced problems over the years with leakage and durability.

Pitch 0 to 10 degrees. And their horizontal lines abound in the west and in urban areas. Traditional homes often have sections of flat roof over shed dormers above porches and garages and on balconies. Building a loft in the roof cavity is easy and provides much more storage space than either the gable or saltbox sheds.

The foundation also helps to keep the shed off the ground preventing dampness and rot. It provides a flat level stable base on which to build your shed. Underneath the basics flat roofs are usually constructed with a ceiling nailed to joists which support a deck usually wood in residential construction a vapor barrier insulation and a roof board. This involves covering the roof in epdm and then adding a frame that can be filled with soil and planted with a mix of grass and flower seeds.

Skillion roofs are one of the simplest roof styles used in shed building. If your shed roof is flat or has a pitch of 18 degrees or less consider building a green roof on it. Saltbox roofs look like skillion roofs but with an extra short slope opposite the long angled plane like an upside down check mark.
