Roof geometry and truss selection: A practical checklist — RiverTruss educational resource

Why this matters

Roof geometry influences truss families, framing intersections, drainage, ceilings, mechanical space, and the final appearance of the building. A checklist is useful when it records decisions and evidence, not when it becomes a box-ticking exercise.

Choosing a truss form from a catalog without testing the whole roof can create conflicts at intersections.

A practical framework

  1. define slopes, hips, valleys, and overhangs
  2. coordinate ceiling and mechanical requirements
  3. test intersections and bearing conditions
  4. review the result in three dimensions where useful

Questions to answer

  • What must be true before this decision is safe to advance?
  • Which fact should be verified by a document, site observation, or qualified professional?
  • Who owns the next action, and when will the record be updated?

Common failure modes

  • Starting with a preferred answer and collecting only confirming facts.
  • Leaving the owner of a task or the date of the next review unstated.
  • Treating a preliminary screen as a final approval.
