Roof Access

[snowocean]

I am working on a project where the owner prefers a stairway be provided to roof rather than ladder. We are looking into a roof access hatch that has a stair integrated with the hatch, but are running into some tight headroom clearances. I was curious if anyone knew of any exceptions for headroom? It is technically not a "means of egress".

Ship ladder?

Guess they don’t want that

What is the alternate stair thing called??

Talk to the AHJ.....If someone was making it easier to get to the roof, I do not think I would punish them with MOE headroom....

Roof access is for maintenance and for fire access. no "headroom clearance" exemptions

Mark, we are NOT talking of where a stair to roof is required, just when you put one in so the HVAC guy does not have to climb a 25' ladder with his tool bucket....

I agree with Mark, there is not an exception. Use a ship ladder and headroom should be ok with traditional curb mounted roof access hatch.

Build a roof Hatch dormer to get the correct headroom.

The building code might not regulate it, but OSHA probably does. Don't use the typical 2 ft. x 3 ft. hatch, it will take a 4 or 5 ft. long hatch to give you the headroom.
