<DIV><FONT size=2 face=Arial>We've thought about those 18" QuickMounts
but since there are often large gaps and splits in the shakes that there still
would be plenty of opportunity for wind and ice to drive moisture up to the
point where the lag screw is located, only a few inches above the lowest point
of the flashing. I trust the 12" QuickMounts for composition roofs because
they compress the shingle and help make a good seal around the penetration
(with added Geocell). With shakes it doesn't seem you can have the same
sort of confidence since the shakes are porous and subject to expanding,
contracting, splitting, swelling, etc.</FONT></DIV>

do a weather-tight install on a cedar (or other) shake roof in snow country

SnapNRack flashed mounting points on composition roofs. I can't imagine a
