You did not say if you are going to guy the tower to the building
walls...
If not, you are going to need a very large roof area for the
non-penetrating base -plus hundreds of pounds of sand bags and cinder
blocks. You also need to check the maximum loading per square foot for
the roof too.
To be more practical, I would consider a shorter, 10 feet tower or
tripod, with only half the wind loading.

Subject: [TowerTalk] Roof Tower
My Radio club is moving to a new building. We would like to put up a
Rohn
45, 20FT. tower on the roof. We need the tower to hold 10-12 square feet
of
load. We cannot drill any holes in the roof. We need some kind of flat
base.
The tower will be located next to a 6FT cinder block wall which we can
mount
too. We are looking for any kind of engineering plans or information you
may
have. Please e-mail me direct w2npt@arrl.net Thanks to all.
