Roof Structural Engineering

Structural review for roof alterations, damaged framing and changes to roof loads or connections.

What this covers

Understanding Roof Structural Engineering

Roof work can affect more than the covering. An engineer may assess the supporting structure and connections where damage, added equipment, a different roof system or a proposed opening changes the design conditions.

When engineering may be required

When to involve an engineer

Engineering help may be needed when the roof structure is altered or damaged, or when a reviewer asks for supporting details. The scope depends on the specific roof and proposed work.

Confirm the engineering scope with the professional you engage and any permit requirements with the local building department.

Engineering tasks

What the engineer may review

Topics that may be relevant to the review: TPO roof, beam, column, flat roof, framing and joist.

The engineer can review existing conditions, evaluate the proposed changes and prepare the calculations or design details included in the agreed scope.

Common projects

Project examples

  • Assessing supports before adding rooftop equipment
