SR114 Survey of nail plate corrosion in the roof space of houses near the coast (2002)
Product Description
The objective of this project was to determine the condition of the nail plates in the roof space of houses with concrete tile roofs. Of primary concern is the extent of corrosion of nail plates in the roof spaces of houses that are built near the coast and have concrete tile roofing with no building paper underlay.
This survey gives confidence that, in general, the nail plates in the roof space of houses near the sea will easily meet the 50-year durability requirements of the New Zealand Building Code.
However, for houses built near the coast where the level of salt deposition is particularly high (e.g. a surf beach), this survey does not provide a sufficient level of confidence due to the inability to locate suitable houses in such severe locations for the survey.
