Findings & Recommendations Report For Nambour Roof Inspection
- Minor foot traffic damage present at the front area of the roof. Should not affect the performance of the sheeting.
- No fasteners installed to the batten in image that has been installed, leaves this roof section non-compliant to SA HB 39 7.2. All battens must be fastened. Also note manufacturer requires 900mm end span maximum centres.
- Minor scratches have been touched up In area shown, Bluescope recommends either replacement or leaving the scratches alone if under 2mm in width. The use of touch up paint can void product warranty on the sheeting.
- Valleys not turned down, non-compliant to SA HB 39 refer 5.6. Potential for ingress into the eaves from water drawback.
- Satellite dish still to be installed, multiple cables penetrating the roof are heavily reliant on silicone which has no longevity due to breaking down under the suns UV rays.Non-compliant to SA HB 39 refer 8.6.1. All penetrations must be flashed. Given that there are several cables
coming through one hole it maybe prudent to install multiple dektites or use the PVC gooseneck method using conduit as shown in diagram.
- Foot traffic damage to the roof around the solar panel installation.
- Foot traffic damage in location shown
- New looking scratches wider than 2mm are evident to the existing gutter with the top image to the left of the house entry. Causes unknown. See item #3 for compliance.
Building & Installation Code References from Nambour roof inspection report:
Roof coverings discharging into a gutter to overhang the back of gutters by 50 mm and have the trays turned down 20 mm at 45°.
NOTE: Roof coverings discharging into the gutter should not overhang the gutter so as to
make maintenance of the gutter impracticable.
8.6.1 Collar flashings
Where any part of the roof surface is penetrated by any pipe, pole, duct, flue, shaft, cable or tank support, the penetration is to be flashed to prevent the entry of rainwater, and to permit the roof surface and penetrating object to expand and contract without detrimental effect to any part of the roof.
B 6.5.1 Surface Damage
Badly damaged panels should be replaced and the manufacturer consulted for the best way to remove and replace the panels. Minor damage can often be repaired in situ.
B 6.5.2 Sheet Damage
A dent, split or puncture in the external skin should not be left untreated as it will accelerate corrosion and, in some insulated products, absorb water into the insulation core. On a roof, it is sometimes possible to repair by over-skinning with a matching profiled skin. All edges are to be sealed to prevent moisture getting between the two skins. On a wall, it is not usually possible to over-skin and in this instance replacement of panel is generally the preferred option. The panel manufacturer should be consulted as to the preferred option.
