Do you REALLY need to use this heavy piece of tower for this project? I
can't help you with any suggestions here, but would like to ask, Wouldn't
a nice roof-mount tripod base work better? Seems to me the necessary
beefing up of your roof trusses would be more work than most hams would
care to do, even for a short 8 foot top section. At least maybe attempt to
trade down to a Rohn 25 piece.

Ed's question about beefing-up your roof is a good one!

Assuming it won't be overloaded, why not get one of the Radio Shack tripod
mounts for each leg?

However you do it, it appears some roofing expertise is needed to prevent
leaks. Perhaps a commercial roofer would have some better ideas about
mounting your 45G.

You can call the professional roofer BEFORE you install, or the first
time it rains AFTER you install.

You decide which costs less. ;-)

Happy trails,

Not a job for the handyman , needs addition braces and special sheathing
over the actual roof , save and pay a professional

This reminds me of the Yugo I saw last year parked at the hamfest. It
had 16 antennas attached in various ways, had the passenger seat removed
so he could stack his radios, and had a huge hole in the side for the
coax., neatly plugged by the way with clear caulking. Classy.

Assuming your house is constructed of steel i-beams, just weld the base
of the tower into the steel roof truss and you should be good to go. If
you have a traditionally constructed home of wood, brick, and plaster,
then just go ahead and file a claim with your homeowners insurance,
indicating the cause as owner stupidity. It will save time on the claim
when the tower crashes through your bedroom ceiling at 3 am and pins you
under the ceiling fan.

I once mounted a section of Rohn 25G on my roof. The house was two-story
with a one-story garage. I built a platform out of 2X pressure treated
lumber and sat the platfrom straddling the ridgeline of the garage. Inside
the garage I spanned several rafters with 2X and ran long bolts through the
platform, through the roof, and through the spans thereby securing the
platform to the garage roof. I drilled holes in the platform to match the
25G legs and fastened the 25G section to the platform with U-bolts. I then
installed a Rohn house bracket on the side of the two-story portion of the
house and clamped the tower section into the house bracket. I put a 10-foot
piece of high tensile mast in the tower and mounted a 24-element 432 Yagi,
small tri-bander, and 5-element vertical beam for 2 FM.

The guy who made the initial post also needs to know that there are
roof-mounted towers. They consist of spread tripod legs; mount with bolts
going through the roof, lumber in the roof spanning several rafters/trusses,
and gobs of roofing tar.

Check out these roof-mounted towers:
