I have done 12ft above the peak of the roof without guy wires with a 91XG/Y1317 antennas on a 3ft tripod, but do not recommend, the not having guy wires, a good wind prolly could pull it out of the roof....
Do you have access to the underside of the roof? If so, you can use regular bolts with large fender washers on the bottom side and add 2x4 bracing to the rafters or trusses to make sure that the tripod does not leave the roof with a hole in a wind storm... If you were to go with a 10ft tripod, well braced from below, guy wires would prolly not be needed, and you could prolly get 15ft of height or more out of a 10ft tripod with strong mast...
