Common questions

Does every roof replacement need structural engineering?

No. Structural review becomes more important when the roof work includes deteriorated deck replacement, altered openings, parapet repairs, new rooftop loads, or other changed support conditions.

When do roof openings trigger more than a simple roofing scope?

Once skylights, curbs, hatches, ducts, drains, or other penetrations interrupt existing framing or require new support members, the project usually needs more explicit structural coordination.

Do parapets matter on roof replacement projects?

Yes. Roof-edge details often overlap parapet condition, coping support, and attached roof-access or railing items that cannot be isolated from the roof scope.

Which NYC public resources should teams check first?

Start with the 2022 Construction Codes, DOB NOW: Build, the DOB NOW Public Portal, and DOB's parapet guidance when roof-edge conditions are involved.
