Here is a general list of items that home inspectors typically check when evaluating the roof covering and roof structure of a residential property.
Roof Covering:
- The condition and age of the roofing material
- Any visible signs of damage, such as missing or broken tiles, slates or shingles, deteriorated or badly installed ridge capping and roof valley gutters, or holes in metal, fibre-cement or other roof sheeting; the condition and effectiveness of the roof drainage system
- The pitch (fall) of the roof covering: Is it compliant with the National Building Regulations and Standards for that type of roof covering?
- The condition and integrity of flashing (waterproofing) around chimneys, vents, and other roof penetrations and along intersections between the roof and head or side walls
- The condition and alignment of gutters and downpipes
- Any signs of moisture intrusion, such as water stains, rust or mould growth on the underside of the roof covering
Roof Structure:
- The condition and age of the roof trusses, rafters and other roof timbers
- Any visible signs of sagging or bowing in the roof structure
- The condition and placement of any support beams or posts in the roof cavity
- The presence and adequacy of roof cavity ventilation and insulation
- Any signs of moisture intrusion, such as water stains or mould growth within the roof cavity or on the upper-side of the ceiling structure
- Non-compliant or deteriorated hot water heaters installed within the roof cavity
- Dangerous electrical wiring, or defective plumbing, or air conditioning systems observed within the roof cavity
It’s important to note that the specific items inspected during a home inspection may vary depending on the design of the roof, the type of roofing material, the age and condition of the roof and whether or not the roof cavity and roof is accessible to the inspector.
It’s also important for sellers, buyers, property practitioners (estate agents) and insurers to hire a qualified and experienced home inspector, who is fully-trained in South African building regulations, national building standards and building methods, to inspect and evaluate the roof and all other components of a residential property. All HouseCheck inspectors are SAHITA-certified (www.sahita.co.za).
