Expert Verdict — Reviewed by the SuperArbor Pro Desk

Size the rough opening to the 36 in. x 30 in. curb dimension and level the curb before setting the hatch so the lid seals evenly. At 127.5 lb, plan a two-person lift or use a hoist to place the unit on the roof. Flash the curb perimeter into the roof system per the manufacturer's instructions, and pair the hatch with guardrails or a safety post where fall protection is required.

Follow OSHA fall-protection requirements and verify local roof-access codes before and after installing the hatch.


Order the TRI-BUILT 36 in. x 30 in. galvanized roof hatch for safe, code-conscious rooftop access.
