[Towertalk] Installation of Roof Top Towers on Peaked Roofs?

[Bob Turner]

Roof was reinforced from below.  My Create 9' has about 8' 2" Chrom Moly
4130 sticking out of it.  We installed mast while tower was laying horiz on
roof with 2 legs attached.  Then we stood it up and guyed it.

Antennas were installed top to bottom while mast was vertical.  A friend
climbed the mast up about 3'.  Then 7' alum mast extension was passed up to
him.  This was attached to primary mast with stationmaster type antenna
clamps.  Top antenna was put on mast extension.  Mast extension was slid up
through clamps that were then tightened temporarily.  Next antenna was put
on, and cycle repeats.

I am on the verge of buying a roof top tower Glen Martin RT-936 or Create
CR-45/CR-30 for use on a peaked roof.

My particular "installation" that I am trying to nail down is one of the
following;

Installation Plan #1:
Force 12 C4E
Cushcraft D4 (for 2nd station SO2R)
Tailtwister Rotor

Installation Plan #2
M2 KT-36XA
Cushcraft D4 (For 2nd station SO2R)
Tailtwister Rotor

Maximum Roof Height is at 25 feet, plus the tower height and 10' mast. Max
height will be in the 40-45ft range.
The roof tower WILL BE GUYED AT ALL 4 LEGS (Kevlar rope etc) once it is all
up. (underneath, the rafters will be reinforced, 2x4, 2x6's etc..)

What I want to know is "how did people get the antennas up onto the mast,
roof top tower etc?"
Did you climb the roof top tower and "hoist" antennas up with some Pully/Gin
Pole system (more so for the beams, C4E or M2 KT36XA)

Some vendors have suggested anchoring two legs onto the roof then leaning it
over on its side, installing everything and then raising it all back up.
That sounds like a lot of weight to try and get vertical on a peaked roof,
let alone when it all comes to a sudden stop on the roof once the other two
legs reach the final resting spot.

Any past experience, suggestions, comments or pictures of some installations
would be appreciated.

Thanks for taking the time to help me out.
