I have a commerciasl building 25' wide, 65' deep. Want to construct a rooftop deck 25' x 25', which will be near the front of the building (say starting 5' back from the front parapet). There needs to be a 'castwalk' from the rear of the building roof edge, which wil connect to the deck, and, to stairs coming up from second floor.

The 'catwalk' will bee approx 35' long.

The building has a brand new roof, covered wiht rubber membrane that extends to and over the edge ot the building.

I am thinking I need some sort of truss system that will go from one side of the building to the other (25' wide).

What are suggestions regarding truss material, and how to secure to the building, without damaging the new roof. Cost is, of course, a concern too.

Any suggestions appreciated.

For commercial work you'll need to get compliance from the owner, zoning and the building dept. with permits among many first steps. You'll need plans and most likely a structural engineer just to get permits, if you can, which I doubt.

This sounds like a project for a pro, just the the engineering on the supports for the guard which will be 42" high rather than 36" will be a feat, lots of properly sized metal connectors, detailed & engineered. The access will most likely be considered a fire escape so they would need to be steel, the liabilty insurance will be high and the project difficult to stage. Just to name a few.

This isn't a inexpensive project either, if you get by all of those initial steps. If you live in a coastal or any high wind area, a northern snow load area, or a seismic zone the costs will go up exponentially.

You may want to do a little research, like call an experience commercial construction company for a consultation before you even start putting too much time in.

Thanks; have already gotten permission from the City (subject to plan approval), and have spoken with the contractor who did the other work on the building, including the roof. The question seems to be, what material to make the trusses out of ('regular' wood, then cover with membrane material, which is what the contractor's first thought was), or, pressure treated lumber, which one architect thought would work.

The thinking is to use trusses to span the width of the building (25'). Another question is how to anchor to the building, without damaging the new membrane roof. (The new membrane roof goes right to the very edge of the roof). The stairway up is planned to be a metal spiral starcase, the 'catwalk' from the rear roof access area to the deck itself, would also be the same material as the deck itself, which is that synthetic stuff that looks like wood, but is a resin/wood mix.

Assuming this all can work, any guesstimates as to cost?

Thanks!

It obviously difficult not seeing the project.. but to guess I'd always put the little extra in and go with treated, as that will allow you more choice on the decking finishes, as it'll be exposed with the decking you proposed.

I'd look into a galv. strap system similar to an inverted J hanger & anchor those into the exterior wall structure. They can easily be hidden under some decorative applied finish.

Your costs will vary wildly dependent on your area.

Thank you for your feedback. If you are interested, I could e-mail a couple photos I took of the roof....picture worth 1000 words....that might help you see what the situation is, and maybe help with providing some direction.

Thanks, and Merry Christmas!

Did you ever get that Rooftop patio built? I am currently looking into this for my commerical project. How much did it end up costing you?

Thanks!
