      1. Rafter Spacing 

        1. Rafter spacing is the horizontal distance between the parallel rafters measured from one rafter's center to the next one

        2. The standard roof rafter spacings measured on-center are 12″, 16″, and 24″

        3. Rafter spacing needs to depict attic space below the proposed panel placement

          Examples: 

           

      2. Rafter Depth

        1. Rafter depth is the vertical distance between the top and bottom edges of a roof rafter.

        2. The most common available lumber sizes used in roof framing include 2″×4″, 2″×6″, 2″×8″, 2″×10″, and 2″×12″

        3. Rafter depth needs to depict attic space below the proposed panel placement

          Examples:

           

      3. Rafter Type/Overall Attic

        1. Overall Attic is the space or room at the top of a building, under the roof, often used for storing things.

        2. The most common attic/truss types used in roof framing include Simple Fink, Queen, Howe, and Fan. 

        3. Overall attic needs to depict attic space below the proposed panel placement

          Examples:

           

      4. Measurements of the top cord and spacing between support beams

        1. Measurements of the top cord depicting spacing between support beams

        2. Top chord span from bottom to diagonal and diagonal to peak

      5. Wood grade stamp of top cord

        1. Wood grade stamp of top cord, this is the rafter attached to the roof plywood

        2. ALL photos need to depict attic space below proposed panel placement

           

      6. If to be built: blueprints/building plans from the manufacturer
