The pitch of a roof is measure in a simple way. Rise over run. By this it means that, given the standard example of a 4/12 roof ,for every 12 inches or one foot of distance or run there is an according rise of 4 inches in height. If you wish to determine this you need to know the length of the rafters and then the height from the center of the rafter to the peak of the roof. For instance if the rafters happen to be 24 feet long that means that the run is 12 ft and if the height from the bottom of the rafter to the peak is 8 feet then you have a 8/12 pitch roof.
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.
The horizontal board that connects two rafters on opposite sides of a ridge board is called a collar tie. It helps to stabilize the rafters and prevent them from spreading apart, ensuring the structural integrity of the roof.
Relates in many different ways you are constantly working with fractions, there are different formulas for different things like figuring out the rise and run on a set of steps or the rafters to frame a roof.

Framing rafters are typically installed in a roof structure by first determining the spacing and angle needed for the rafters. Then, they are cut to size and placed between the ridge board and the top plate of the wall. The rafters are secured in place with nails or screws, and additional bracing may be added for support.
Roof joists are horizontal beams that support the ceiling and the weight of the roof, while rafters are sloped beams that support the roof itself. Joists are typically found inside the building, while rafters are located on the exterior.
You can see the rafters of the roof very clearly here.
The recommended spacing for 2x6 rafters in a roof structure is typically 24 inches on center.
At the peak of the roof where the rafters meet instead of the rafters meeting each other, there is a beam between them that they rest against. It runs the length of the roof peak.
The maximum span for 2x6 rafters in roof construction is typically around 9 feet.
The maximum span for 2x6 rafters in residential roof construction is typically around 9 feet.
You can effectively insulate roof rafters by installing insulation material between the rafters and sealing any gaps or cracks to improve your home's energy efficiency.
in need of rafters on my roof,before i can have it weatherized
Roof rafters in residential construction projects are typically framed by cutting and assembling them on-site to form the pitched roof structure. They are usually placed at regular intervals along the top of the exterior walls and are secured in place with nails or screws. The rafters provide support for the roof sheathing and help distribute the weight of the roof evenly.
