Roof trusses bowing and their danger, in Forest Lake a Southern suburb of Brisbane.
Bowing of roof trusses-Danger. Identified by Peter Weddell owner/operator of Qld Home Buyers Inspection Service and Queensland Building Inspection Service, QBIS.
Sideways bowing of roof trusses:
- Roof trusses supporting this concrete tiled roof were bowed sideways considerably, some as much as 100 mm.
- This degree of bowing far exceeds the acceptable tolerance level
- Potentially making the roof structure structurally unsound.
- The roof structure could collapse in differing weather conditions.
Roof trusses are not designed to take sideways pressure.
Previous misleading inspection report:
This major fault was not identified in the previous building inspection report carried out for the current owners/sellers, this omission cost them a sale!
Remove roof tiles, straighten the roof trusses, replace ceiling linings of affected areas.
This would be costly and disruptive as it would not be achievable safely with the owners still occupying the house.
Bowing of roof trusses-Danger.
In most cases it would be more economical to have the roof tiles replaced with metal roof sheeting. This would require more securing of the structural for tying down but unlikely to require restructuring.
These are examples of the importance of employing a competent independent building inspector. Peter Weddell has the experience and knowledge and is working in your best interest.
