Hi , I have had 3 rohn 25 sections on my roof for about ten
years . I have never had a problem and that includes hurricane force winds and
a tree falling on a guy and breaking it .
I had a twenty foot mast with a force12 c-4 , over that a 432 beam and over
that a 2 & 6 interlaced quad .The mast is now 16 foot . That was cut because it
was rusting .
Three pieces of about two inch angle iron was attached to
the roof beams as a base .Each piece of angle iron is about 2 foot long . It is
guyed at the 15 foot and thirty foot point .The guy anchors are attached to
beams also .
This was done for me by pro who normally worked on large
business buildings . If you have any more specific questions , you can contact
