Findings & Recommendations Report For Cedar Creek Roof Inspection

  • Foot traffic damage dent in location shown.
  • Aerial base is not flat, and it was noted the screws were loose, likely occurring from the wind moving it as there it is not supported correctly, ingress may occur around the screws if not rectified.
  • Screws missing in several locations as referenced in images
  • Exposed copper piping will reduce the lifespan of the sheeting as future corrosion will occur from copper saturated water run-off.
  • A sheet has been laid on top of another sheet in this location, this will cause moisture from condensation to become trapped between the two sheets that will lead to corrosion and a reduced lifespan of the sheets.

4.4.2 Corrosion due to drainage

Metal roof drainage system components shall be designed and installed to prevent corrosion, erosion, or both, due to drainage from metal and non-metal roof drainage system components and, where applicable, cladding.

A2 Roof Condensation

The roof is the most exposed element of the building fabric. On clear still nights the roof temperature often drops below the outdoor air temperature as it loses heat via radiation to the cold night sky. The cold roof combined with the moisture generated at times within homes makes overnight condensation within roofs likely; however, condensate is also likely to dry during the day due to high roof and roof space temperatures. While it is good practice to minimize the risk of condensation, significant problems will usually only eventuate if condensation is persistent or condensate becomes trapped. Generally, the risk of persistent condensation in roofs is greatest in the coolest climate zones (NCC climate zones 7 and 8). Persistent condensation may also eventuate in other climates with poor detail or in special circumstances, such as when high internal or ground moisture le, els are not controlled, roofs are unable to adequately dry due to lack of outdoor ventilation or roofs are perpetually shaded.

A3 Problems Caused By Condensation

Persistent condensation or condensate that is unable to dry can cause problems in buildings. The cause is often due to poor design or inappropriate use of materials and once present can be difficult to eliminate. Problems that may be encountered include rotting of timber or corrosion of structural steel components, mould growth that may affect indoor air quality, reduction in the efficiency of bulk insulation, physical deterioration of ceilings made from absorbent materials and staining of walls and ceilings. Often repair of condensation effects and retrospective control measures are significantly more expensive than measures available to prevent condensation in the first instance.
