Altered roof trusses danger. Identified by Peter Weddell, owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS.

Alteration to roof trusses causing dangerous situation

Danger of altered roof trusses, what were they thinking? 

Cutting out the bottom chords of these roof trusses to fit a garage door could have proven dangerous, if not for advice from Peter Weddell on how to rectify the problem, economically.

  • Bottom chords (horizontal main supports) of the roof trusses have been cut out to accommodate the tilt-door track above this garage.
  • Significantly weakening of the roof structure by altering the roof trusses.
  • Creating a high probability of the roof collapsing.

Economical solution to a potentially serious problem:

  • Replace the concrete tiles with metal roof sheeting.
  • Reinforce damaged sections of the roof trusses.
  • Fit more securing to the roof structure for tying down.

More securing would be necessary to the roof structure when having  roof tiles replaced with metal sheeting.

This problem was brought to the attention of the seller and fixed before it became a more serious problem.
