1) Draw up an overhead plan view of all your gear you intend to put on the roof, using some basic CAD software, to scale. This can be done in Visio, even. Show the dimensions/footprints of each thing and annotate it with weight in kg.
2) Get a copy of the architectural/engineering plans to the building. 3) Provide both your plan and the building's structural plans to a professional engineer (wet stamp P.Eng), pay them to do a structural loading calculation for the roof beams, etc. On Thu, Dec 18, 2014 at 6:09 AM, Jon Langeler via Af <[email protected]> wrote: > > We've been asked to provide a study of rooftop weight allowances in order > to install a bunch of rooftop mounts.
