I had a 5BTV vertical on my roof at an earlier installation and used 
a swivel bracket mounted directly on the roof with three guy 
ropes.  I had four radials on each band stretched across the 
roof.  It was a cedar shingle roof.  A friend of  mine used a tripod 
and it worked for him, but it was a bit harder to get the antenna 
onto the tripod.
