Description

Roofs perform a critical function - they are the umbrella protecting the building from the outside environment, with a particular focus on protection from water. Good performance with only modest maintenance can be achieved with careful design, cladding selection and installation.

This BRANZ Facts series outlines the minimum performance requirements under the New Zealand Building Code, paths to compliance, the factors that influence the performance of roofs, roofing materials and common problems.

No building element fits in the ‘out of sight, out of mind’ category better than roofs. Good performance with only modest maintenance requirements can be achieved with careful design, cladding selection and installation.

When selecting a roof cladding system, a number of influences need to be considered. These include design, environment, owner and installation influences.
