Shed roof plans
There are many types of roofs when it comes to small house plans and today we are going to look closer at one of them – shed roof, also known as pent roof or skillion roof: a mono pitch roof slightly sloped in one way. It is one of the simplest roof types, well suitable for tiny houses, small cabins, garden sheds but also patios, shelters, garages or different extensions to residential buildings.
As apparent, shed roof can be seen on both individually standing constructions as well as roofs leaning to a wall, fence or another roof and it adds a modern, minimalistic look to the structure.
Advantages of shed roof
Shed roof design combines advantages of gable roof and flat roof, with beams spanning between two walls, one of which is higher than the other one thus creating a slant, usually ranging usually ranging from 7° to 35°; depending very much on specific small house design, its proportions and weather conditions of the location. This leads to eliminating or minimizing spaces with sloped ceilings, providing more spacious interior instead, yet sufficient drainage is still ensured thanks to the roof slant. The additional space can be used to install large windows or additional clerestory windows, which brings more daylight in and will visually enlarges the room.
Another benefit of mono pitch roof is that is an opportunity to extend a roof and gain bigger overlap, which does not need an internal gutter and can be used to create a covered deck. Although it is important to make sure the shed roof with cantilevered part is designed properly to avoid any damage for example due to snow load, etc.
Shed roof framing
Without need for too many parts or complicated construction process, shed roof construction can be built easily and fast with quite low expenses. It distributes the load equally to the load bearing walls, as it does not include many roof members; the main shed roof parts are rafters and beams. Rafters are the sloped elements that run from front wall to the back and support the roof cladding and ceiling. Beams are placed horizontally. In case rafters are longer than what the recommended length for them to be without support, beams serve as blocking, providing the support and ensuring the roof structure is solid and stable.
To the top of that roof sheathing is attached. For shed roof design, typical roofing made of roof shingles or tiles is not suitable. Large format, one piece metal sheets or shed felts are used with various profiles such as bitumen sheets or PVC foils.

- Batten fixing the foil creates a ventilated gap between the osb boards
- Suspended ceiling
- Thermal insulation
- Vapour barrier
- OSB boards
- Corrugated metal
