B VERY careful when using treated wood on a metal roof. It will attack
and eat right through it.
I caught my first do-it-yourself mount before it got through the roof of
a multi-million dollar house.
At a minimum use a roof pad. If you can't find one for cheap then ask
around your friends with horses. Use a stall mat cut to the right size.

For ultra low-cost non-penetrating roof mounts, I've been playing
around with J-Bars salvaged from discarded Dish TV equipment, mounted
to a base made from scrap treated lumber and weighted down with
cinderblocks. Then, I mate a vertical length of EMT conduit, 1/2" or
better yet 3/4", using a couple conduit hangers.

Maybe this can give you a general idea, although this would definitely
have a conspicuous DIY look. (I just try to make these things in
batch, to conserve on labor.)
I should note the latter photo, which might be of the most interest to
you, is now out of date. The wood beams making up the base were
rearranged into a "V" shape for more width, with a metal brace
spanning the mouth of the "V" for stiffness. Likewise the 24inch
vertical mast was replaced with a completely straight section of EMT,
instead of that weird zig-zag piece I originally happened to have
lying around.

Hello list,
I am setting up a PtP link between two gas stations for a client.
I am going to be using two Nanostation M5 units going about 1/2mi
diagonally across a highway. I'd like to mount them to a 5ft mast
then to a non-penetrating roof mount, as the only place with clear
line-of-sight is on the roof of both gas stations. Flat roof
without much of a lip to mount an antenna to. All of my Google
searches come up with much larger non-penetrating roof mounts, 3'
or wider, which are designed for much larger and taller masts.
Also very pricey, $150 or more each.
Does anyone make a small non-penetrating roof mount, say 2ft
square out of metal with an attachment to hold a 5ft mast or
including a 5ft mast? Maybe a single cinder/cement block to weigh
it down would be all that is needed. Won't ever need to go higher.
Or do you have another suggestion for mounting?
Thanks in advance,
Josh
