Elanora Roof Inspection Report Purpose:

Provide a roof condition report following a Elanora roof inspection. References are made to several Australian building standards including N.C.C 2016 Vol.2, AS 1562.1, AS 1562.3 & SA HB 39 2015: The Installation Code for Metal Roofing and Walling. For more information on these building codes, click here. Manufacturer’s Instructions that are referenced are attached to the report. We also provide recommendations to extend longevity.

Findings & Recommendations In Elanora Roof Inspection

  • Several tiles around pipe penetrations have not been cut to a satisfactory standard, with lead Dektites showing signs of deterioration with splits present. Installing lead Dektites as shown below will stop future ingress and will increase longevity.
  • Additional pictures are showing lead Dektites.
  • Evidence that numerous damaged tiles and missing corners are consistent throughout. Replacing damaged roof tiles with new ones will stop future ingress and will increase longevity.
  • Evidence that roof tiles in various areas have been sealed up from a previous repair using silicone, this has no longevity and breaks down under the sun’s UV rays. This does not comply with the manufacturer’s instructions and is likely to trap in water and lead to ingress. Replacing damaged roof tiles with new ones will stop future ingress and will increase longevity.
  • Evidence of numerous damaged and missing corners (example marked on photo) of the tile water courses have been identified, there may be more present, however, it was not possible to identify further tiles due to them being placed on top of one another. In heavy driving storm conditions, ingress is possible. More investigation is required. Rectifying these issues will stop future ingress and will increase longevity.
  • Evidence that a portion of the roof tiles have become raised and are not in their correct position, resulting in gaps. This is non-compliant with the manufacturer’s instructions and poses a potential risk of the tiles being blown off during severe storm conditions. To prevent any future damage to the roofing materials and ensure longevity, it is essential to rectify this safety issue and stop any possibility of water ingress.
  • Skylight frames and lead flashings have reached the end of their serviceable life span, frames are heavily corroded, and require replacement to prevent the spread of more corrosion. The gutter will eventually corrode from dissimilar metal run-off. Also, evidence of a previous repair to the skylight using silicone which has no longevity. Rectifying this issue will stop future ingress and will increase longevity.
  • Evidence that the aerial cable support bracket bolts, which have been placed through the lap of the roof tiles, are sealed with silicone, this has no longevity. This is likely to trap in water and cause future ingress. Installing lead Dektites as shown below will stop future ingress and will increase longevity.
  • Evidence of deteriorating ridge caps pointing in various areas, this is producing gaps and we expect further failures to cause ingress. Also, weep holes are only present in various areas, noncompliant with NCC refer to 3.4 as shown. Loose ridge caps, which are at risk of falling off in high wind conditions. Rectifying these issues will stop future ingress and will increase longevity.
  • Additional pictures are showing inefficient tile caps throughout, slight cracking to mortar to the ridge tile caps due to thermal movement.
  • Chase flashings and lead flashings have reached the end of their serviceable lifespan and are showing signs of deterioration with splits present. Flashings have not achieved the 150mm effective coverage non-compliant with SA HB39 refer to table 8.1.4 as shown. Chase flashing is noticeably lightweight and has not been secured to the roof tiles, and this is likely to blow up in heavy wind conditions and lead to ingress.
  • Evidence of a previous repair to the lead flashing using waterproof membrane and silicone, which lacks quality and longevity. Chase flashings and lead flashings have reached the end of their serviceable lifespan and are showing signs of deterioration with splits present. Flashings have not achieved the 150mm effective coverage non-compliant with SA HB39 refer to table 8.1.4 as shown above. Chase flashings are noticeably lightweight and have not been secured to the roof tiles, and this is likely to blow up in heavy wind conditions and lead to ingress.
  • To prevent damage from excess water flowing from the high level, it is imperative to install a gutter and downpipe in the areas shown. This proactive measure is crucial in minimising the risk of internal and external damage during rain events.
  • Sarking is in average condition, however, it is showing signs of wear and tear in various areas through small splits and holes.
  • There is evidence of sarking present, and the pitch of the main roof is approximately 17.45- degrees, as shown. The minimum roof pitch for this design of roof tile is 20-degree pitch without sarking and 15- degrees with sarking. The use of sarking is additional protection.

Conculsion Outlined In Elanora Roof Condition Report

There are many issues highlighted in this report caused by a lack of maintenance, repairs, and faults. These issues have been aggravated by recent weather events. Repairs to the roof are evident and some have only provided a temporary fix. It would be beneficial to have these issues investigated further by a licenced tradesman to commence with the roof being restored or replaced.
