Findings & Recommendations Report For New Farm Inspection
- Sheets double lapped, high chance of accelerated corrosion here as moisture gets trapped between the sheeting. Noncompliant to manufacturers installation instructions. Remedy is to remove and replace with single lap sheets.
- Vent pipe through the lap of sheeting affecting the anti-capillary feature and already shown signs of ingress, noncompliant to AS 1562.1. A solution is to install tray flashing to cover lap and install new Dektite.
- Soaker trays at skylights have silicone failure, show signs of ponding and water flow is being blocked by the conduits. This is an area of concern as the trays aren’t adequate for the inflow of water. Several patching attempts have been made here. Remedy is to install a box gutter valley with falls to run across the front and down the sides of the skylight penetration to allow correct water flow and alleviate ponding. Reinstall new sheeting and flashings around penetration.
- All roof penetrations are ponding and blocking laps reducing water flow and causing ingress. Non complaint to SA HB 39 refer 8.6. Remedy is to re-flash all pipes, penetrations and tray flash to the top barge cap.
- Sheeting is short to top barge roll cap, sheets not turned up to stop ingress. Remove gable roll, turn sheets up and replace with a barge capping that will give adequate protection.
- Same situation as #5 although this has been patched and solely reliant on silicone, joints not sealed and unsure if sheets have been turned up. (didn’t want to deconstruct and disturb silicone). Remedy removal and replacement with a correctly folded barge capping.
- All eaves gutter shows severe signs of ponding corrosion with the exception of the front entry roof. Non-compliant to AS 3500 refer 4.5.3. Remove and replace eaves gutter where required.
- AC units discharging copper saturated water directly onto roof sheeting, non-compliant to AS 3500 refer 4.4.2. AC drainage pipes should be run directly to the gutter outlets to prevent further corrosion.
- Sheet lap corroding. Replace sheeting.
- 55% Extensive hail impact damage on all corrugated roof surfaces.
Roof Inspection Conclusion Based On Findings:
Due to the extensive ingress issues, poor repair works and the hail impact damages, the only feasible solution to rectify all of the issues noted in this New Farm roof inspection would be to re-roof all corrugated roofs and replace the guttering where required.
