ROHN 55G Tower Base For Flat Roof Mount R-FR55G
ROHN FR55G Plate For Flat Roof Mount Tower Placement
The FR55G bolts directly to Water-tight and Reinforced Flat Roof Surface for a guyed 55G Tower, but Cannot be Used as a Self Supporting Base Plate (none exists). This Tower Base uses double bolted joints which are proven to be the best method of joining tower sections for sturdiness and dependability. The 55G tower can be used guyed, self-supporting or bracketed configurations according to specifications in the ROHN catalog. As a guyed structure, it can rise to a maximum of 400 feet. However, Roof Mounted Tower Options may limit Potential Height considerably. Self-supporting and bracketed heights depend on loading and are also specified in the ROHN catalog (see Footer below).
There is no Wind Load vs. Height Guidance to be found this type of Mounting in any of the Specification Literature for good reason... You need to Consult an Engineer to determine the Load Bearing Capability and Wind Speed Survivability of such an Installation. Guying is an absolute must, but remember that guying will simply increase the down pressure onto the Base support, which in this case, is your Roof! I would imagine that any Roof mounted structure is going to attract the attention of other Building Owners, Code enforcement and the Insurance adjuster. If you cannot find someone local to evaluate the registered plans for your Flat Roof Structure, ROHN may be able to put you in contact with someone who can.
