I would check the facia board for nail heads. The rafters/trusses are 16" or 24" o.c. If you can find protruding nail heads in the facia and measure the distance between two of them, you can determine where the rest are.
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.

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.
Ceiling rafters in a building's structure provide support and stability to the roof, helping to distribute the weight of the roof evenly and prevent it from collapsing.
