INSTALLING THE MOUNT ON A WOOD FRAMED ROOF
You can install the satellite dish onto a wood framed roof. You must use the brace kit. The minimum size for roof truss members is 2
inches x 4 inches. Roof rafters must be nominal 2x material (2x4, 2x6, etc.) Either size roof rafters or trusses must be16 to 24 inches
on center. The roof surface must consist of relatively thin, resilient materials, such as asphalt or composite shingles, sheet metal, or
similar materials, over wood sheathing with a thickness of 3/4 inch or less. Satellite dishes cannot be installed on flat roofs, slate
roofs, or Spanish tile roofing made of clay or other brittle materials. The roof pitch (or slope) must be between 3:12 and 12:12.
All center hole lag screws must be centered in the rafter or truss to which they are attached. For this reason, you must be able to
locate rafters and trusses and the center of rafters and trusses with a high degree of accuracy, which can be difficult to do. Home con-
struction varies a great deal. Construction styles, materials, and dimensions can all vary widely. In addition, stud finders give false
readings on multilayered surfaces, such as a roof. Also, you need experience in home construction to be able to determine the exact
location of rafters and trusses and their centers. The satellite dish should not be installed on a wood frame roof unless the interior of
the roof is unfinished so that placement of lag screws can be verified and the rafters or trusses reinforced if necessary.
If you do not have the knowledge and experience to accurately locate rafters and trusses and the center of rafters and trusses with a
high degree of reliability, you should contact a professional satellite dish installer for installation.
Large-timber roofs with frequent spacing of members are also permitted. These are constructed of wood members larger than the
nominal 2x sizes, and include post and beam structures with members from 4 inches x 4 inches and larger. The members cannot be
spaced more than 24 inches on center. Their physical properties must match or exceed those of Spruce-Pine-Fir #2.
