Roof geometry and truss selection: Milestones and timeline — 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 credible timeline is built from dependencies and review gates, not from a desired completion date copied into a spreadsheet.

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

  • Which milestone cannot start until another deliverable is accepted?
  • What review time belongs to a public agency, owner, lender, or supplier?
  • What is the recovery plan if the controlling activity slips?

Common failure modes

  • Showing dates without naming the dependency that makes them possible.
  • Ignoring procurement, review, and decision time.
  • Moving a finish date without showing the cost or scope consequence.
