Rosemount Roof Inspection Purpose:
Provide a roof condition report to AS 1562.1 AS 1562.3 And SA HB 39 2015 The Installation Code for Metal Roofing and Walling and Manufacturer’s Instructions. Provide recommendations to extend longevity.

Findings & Recommendations Report For Rosemount Roof Inspection
- Exposed copper pipe penetration, heavily reliant on silicone which has no longevity, non-compliant to SA HB 39 refer 8.6.1. All penetrations must be flashed.
- Dektite required, ensuring exposed copper is taped/lagged to prevent dissimilar metal water run-off.
- Several fasteners with split/blown out washers across the roof.
- Some sheet laps are not seated correctly in several areas, potential here for ingress during heavy rain events.
- Barge flashings do not align with the sheeting in 2 areas, likely due to the building being out of square, minor potential for ingress as the side turn down has been trimmed back ( cut around
the screws) to allow for the flashing to sit down. More an aesthetic issue. - Dektite required for the coax cable penetration. Foot traffic damage is also present.
- No vent cap installed and the pipe is blocked with insulation.It may be prudent to extend the pipe above the roof a bit further so the cap doesn’t invert the Dektite when installed.
- Fascia has been replaced with a different type of profile/brand and is an aesthetic issue only.A quick google search found the correct product, see below. Original fascia is made by Metroll.
Installation Codes Referenced:
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.
4.4.2 Pierced-fastened Cladding
Fasteners in valleys or crests shall be tightened to compress flexible seals without deforming the cladding or damaging any washers.
Where nails are used, any local distortion shall not extend beyond the area covered by the washer and seal.
NOTES:
- Compressed washers should be used to minimise water leakage and provide cladding performance as per design documentation.
- Care is to be exercised to prevent the entrapment of swarf between the seal and the cladding for both crest and valley fasteners.
