hi, just curious are there any restrictions or limitation on what the dish can be installed on?

specifically we have a building with corrugated aluminum that basically looks like this http://image.made-in...minum-Sheet.jpg ...but not sure if its possible to install it on such material.

Is the corregated aluminum attached to a roof decking or is it attached to only the rafters below.

For a stable install the mount needs to be lagbolted or otherwise connected to a very firm base.

The irregular surface of the corregated roofing will also create a problem.

I think you are asking for trouble there. I wouldn't consider it unless, like Jim says, it is a very firm base beneath it and then I wouldn't be sure.
I mounted a dish on a 4X4 post attached to a fence post which went into the ground and was very firm indeed. The only problem was that the ground here is clay and it expands when wet and contracts when dry. I had to repoint the dish shortly into the rainy season and shortly into the dry season. That got old after a couple of years so found a better mounting place.

externally, the roof, overhang and walls are made up of it. basically the entire outside of the building is made of the stuff. this picture is identical to how the corrugation lines run http://rowenamaxwell...iron-shed21.jpg
not sure if that will help.
ps. anyone know how heavy the dish equipment is?

It could be done but to me the simplest way would be to put a pole mount right next to the building.

We did what was supposed to be a temporary install on a building made of that. We did however put up a 2' x 2' sheet of treated plywood that they had on hand on the building and then used regular wood lags into that. Just happens that the plans to relocate the building and dish never happened and that dish was there +10 years with no issues.

If the dish had been fastened directly there would have been too much side to side play when the wind blew on it.

i've considered a pole.. only problem is it would probably need to be 10 feet high b/c of the line of sight clearance issue. basically the same height as the building. if i could attach it to the roof somehow, that would be ideal. maybe i could use something like concrete board, which supposedly its very durable.

If you dont mind attaching something to the roof you could bolt a non penetrating roof mount to the roof.

You could install a corrugated roof mount (some dealers refer to this as a NPRM). :D
