Roof design, covering and waterproofing
Introduction on Roofing
Home inspectors do their best to inspect the roof system within the inspection time allotted.
Inspectors inspect the roof covering, drainage systems, the flashings, the skylights, chimneys and roof penetrations. Home inspectors are not required to inspect antennae, interiors of flues or chimneys or other related accessories.
This inspection report does not comprise an exhaustive investigation of every installation detail of the roof system according to the manufactures specifications or construction codes.
It is often impossible to detect a roof leak except as it is occurring, or unless specific water tests are conducted - such tests are beyond the scope of an inspection. We recommend that buyers should ask the sellers to disclose information about the roof.
Where deemed necessary clients should consider hiring roofing professionals to inspect the roof further before closing the sale of the property.
Fibre Cement Slates:
As fibre-cement slates weather over the years the slates tend to start absorbing some moisture, which may eventually lead to curling at the corners and compromised waterproofing. Painting will delay this process.
Asbestos Cement Roof Sheeting:
Fibre cement roof sheeting and slates on South African buildings built prior to 1980 probably contain asbestos. Asbestos roofing becomes a health hazard when the sheeting deteriorates and asbestos fibres invade the environment. Regular painting can prevent this happening.
Many property owners are unaware that they have a legal obligation in terms of the Asbestos Regulations to conduct Asbestos Surveys on their properties on a regular basis, not exceeding two yearly intervals, and to maintain their asbestos in a good, safe condition.
