The maximum span for 2x6 rafters in roof construction is typically around 9 feet.
Joist hangers for rafters are used in construction projects to provide structural support and stability by connecting the rafters to the supporting beams or walls. They help distribute the weight of the roof evenly and prevent the rafters from shifting or sagging over time.
Purlins are used on double roofs. They effectively reduce the span of the rafters and limit their size to ecenomical sections.
The recommended dimensions for a rafter table used in constructing a roof typically include the length, width, and thickness of the rafters. These dimensions are usually determined by factors such as the span of the roof, the load it needs to support, and the type of roofing material being used. It is important to consult building codes and structural engineering guidelines to ensure the rafters are appropriately sized for the specific project.
Most sloped roofs are supported by a purlin bracing system. A board the same size as or larger than that of the rafters is placed on edge perpendicular to the rafters and attached on the bottom side of the rafters. Legs are then placed under the purlin brace and with the top notched under the purlin and the bottom placed on and attached to the top of a wall, thus transferring the weight of the roof from the rafters to the top of the walls.
A purlin is a structural part of a roof which is used to support rafters and carry the roof cladding By supporting the rafters they allow for longer roof spans to be created allowing for wider buildings to be created.
Poplar.
This will depend on many things including:the spacing between the rafters;the spacing between the studs;the pitch of the roof;the wind zone;the type of fixings being used; andthe span of the rafters.Contact your local authority or a competent local builder or architect regarding what can be done in your area.
2x12 lumber is commonly used in construction projects for structural framing, such as floor joists, roof rafters, and stair stringers. It is also used for building large beams and headers to support heavy loads in buildings.
you can use trusses or rafters.
That is what everyone has used for decades.
Fasciaboard is a type of roof trim that is commonly used on houses. It is mounted on the exposed ends of rafters or the top of exterior walls
