How does a rational design impact a roof inspection?

There are many levels of competence within the roof construction industry and the cheapest building quote can easily become the most costly exercise in the end. But once having received the formal completion certificate, the homeowner is protected.

The National Building Regulations require that roof designs be checked on site and signed off by the responsible engineer.  This is the law.

Furthermore, failing to obtain the completion certificate will prevent the homeowner from obtaining the occupation certificate for the house/or modification of the roof that was completed.

All rational designs by engineering calculation must comply with the requirements of the National Building Regulations. They are sophisticated and reliable.

Roof inspection and formal certification by a registered engineer for roof safety is the best money spent, since the roof is the most vulnerable part of the structure.

Rational designs by engineering calculation must comply with the requirements of the National Building Regulation:

SANS 10160 – The loadings and procedures according to structure/building design.

SANS 10163 – The structural use of timber.

Manufacturing and erection procedures:

SANS 10243 – The manufacturing and erection of timber trusses.
