Rafters are usually on 2 ft. centers.
The rafters carry the dead load of the sheathing and roofing material, and the live loads above
For wood framing it can be 16", 19 1/4" or 24 " on center.
It is usually 16 inch.
The easiest way is to use a tool called a pitch finder that can be placed on top of the roof, on gable end soffit, or in the attic under a rafter to find the pitch. This is a special tool and can also be used to find level, plumb, or any angle in between. I have provided a link that goes into great detail on three different methods to find the existing roof pitch.
Rafters are usually on 2 ft. centers.
The recommended rafter spacing for a metal roof installation is typically 24 inches apart.
A rafter is part of a roof, it supports the roof.
The rafter spacing on a flat roof mobile home typically ranges from 16 to 24 inches on center, depending on the design and load requirements. It's essential to adhere to local building codes and standards, which can vary by region. Proper spacing ensures adequate support for the roof structure and helps with water drainage. Always consult a structural engineer or building professional for specific recommendations based on your mobile home's design.
The standard size of a roof rafter typically depends on the span and load requirements, but common dimensions are 2x6, 2x8, or 2x10 inches, with lengths varying based on the roof design. For residential construction, 2x6 rafters are often used for spans up to 10 feet, while larger spans may require 2x8 or 2x10 rafters. The spacing between rafters is generally 16 or 24 inches on center. It's essential to consult local building codes and a structural engineer for specific requirements.
A broken hip rafter refers to a structural failure in a roof system, specifically involving the rafter that supports the hip of a hip roof. Hip rafters are angled beams that run from the ridge of the roof to the corners, providing support and stability. When a hip rafter breaks, it can compromise the integrity of the roof, potentially leading to sagging or collapse. Repairing a broken hip rafter typically requires replacing the damaged rafter and ensuring proper support is restored to the roof structure.
The last rafter on a building is typically called the "ridge rafter." It runs along the peak of the roof and connects the tops of the sloping rafters, providing structural support and helping to define the roof's shape. The ridge rafter is crucial for maintaining the integrity of the roof framework.

Rafter ties are horizontal beams that connect the rafters at the bottom of the roof, while collar ties are horizontal beams that connect the rafters higher up on the roof. Rafter ties help prevent the roof from spreading apart, while collar ties help prevent the roof from sagging.
A common synonym for "roof support" or "wooden beam" that is six letters long is "rafter."
The maximum allowable 2x6 rafter span for a residential roof structure is typically around 9 feet.
To find a roof rafter near the edge of a wall, first locate the wall stud, as rafters are typically spaced in alignment with them, usually 16 or 24 inches apart. Use a stud finder or tap along the wall to identify the stud locations. Once you know where the studs are, measure up from the wall to find the rafter, which should be positioned at the same spacing as the studs. Alternatively, you can access the attic and visually inspect the rafters to confirm their location.
