How do i install an aluminum sign to the top of the roof of a building if the top is flat and does not have any posts on the sides?
Does it holds if I place some steel frames attached to the beams of the roof?
If you don't know how to do it... my best advice is to partner up with a shop that does.
This could get ugly for you if the sign structure fails...
when i owned a retail direc tv office i would always push "non pen roof mounts"
their great..they were just a metal frame made of 1"x1" angle iron..the base was designed so that you could put 8 concrete blocks on it...and it would hold the big high def satellite dish(bout 50lbs) and it catches a lot of wind..
maybe something like this would work but on a larger scale??
well..like i said....it was for a satellite dish..lol
he might be able to adapt and make something on a bigger scale to work for his sign..just tossin ideas out there
I have installed signs all over including NYC and every install varies to some degree. you need to be familiar in framing and construction to quite a degree and have an idea as to what your fasteners shear streanth capabilities are. I wouldn't give advice with out being able to see the construction of the site as well as the sign construction and even then with out having the experiance behind you to having a "feel" of the material your penetrating into it probrably would not be a good idea to self install.If you don't know how to do it... my best advice is to partner up with a shop that does. No offense meant, but seriously... what if it falls? What wind load is your frame going to be able to take? What does your city, county require?
Around here you have to permit a sign and that includes the detailed plan for installation... complete with pretty pictures of our frame construction...
This could get ugly for you if the sign structure fails...
THANKYOU ALL for advices. What I did, since I couldn't find any help or any other shop with this specific experience in my town, I hired a carpenter
