Air Shammee Mounting

[JamboWash]

i just purchased some air shammee air dyers for my Self serve wash , debating on mounting inside the bay or on the roof , I am leaning towards mounting on the roof which would reduce the noise in the bay, but my roof canopy is open on the top so worried about rain , weather doing the damage. anyone mounted them on the roof can share their pros and cons.

I have one site with them on the wall and another in the attic. The ones on the wall are more visible and get used more. They are louder though, but since my office is nearby it is nice to hear when then are on and being used lol.
