Pacific Pines Roof Inspection Report Purpose:
Provide a roof condition report to N.C.C 2016 Vol.2, AS 1562.1, AS 1562.3, SA HB 39 2015: The installation Code for metal Roofing and Walling and Manufacturer’s Instructions. Provide recommendations to extend longevity.
Findings & Recommendations In Pacific Pines Roof Condition Report
- Damaged, cracked roof tile and barge cap have been identified, replacing these damaged tiles will stop future ingress and will increase longevity.
- Evidence that the lead flashing and roof tiles at the base of the valley 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. Rectifying this issue will stop future ingress and will increase longevity.
- Evidence that a hole is present between barge cap and lead flashing. By sealing up the gap this will stop future ingress and will increase longevity.
- Evidence of numerous damaged, slipped roof tiles to the rear main roof valley, resulting from lack of tile clips being installed. Also, evidence of silicone being used to hold tiles into position, resulting in blocking water flow to the lap of the tiles. This is likely to trap in water and lead to ingress. Valley roof tiles have not been cut to leave 100mm to 150mm channels as per manufacturer’s instructions, if not rectified may lead to ingress. Information regarding installation of roof tile valley is shown below.
- Evidence that damaged, cracked roof tiles have been identified where the satellite dish has been installed. By replacing damaged roof tiles this will stop future ingress and will increase longevity.
- Evidence of numerous damaged, slipped roof tiles to the front main roof valley, resulting from lack of tile clips being installed. Also, evidence of silicone being used to hold tiles into position, resulting in blocking water flow to the lap of the roof tiles. This is likely to trap in water and lead to ingress. Valley roof tiles have not been cut to leave 100mm to 150mm channels as per manufacturer’s instructions, if not rectified may lead to ingress. Information regarding installation of roof tile valley is shown above.
- Deteriorating and loose ridge caps and pointing are consistent throughout, which are producing gaps and we expect further failures causing ingress. Rebedding and repointing the ridge caps tiles will stop future ingress and will increase longevity.
- More images of deteriorating and loose ridge caps to the main roof and front entrance.
- Evidence of ridge caps being recently restored where the property joins in the middle; however, weep holes are not present, non-compliant to NCC refer 3.4 as shown, if not rectified this may lead to ingress.
- Evidence of damaged and missing corners 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, more investigation is required. Rectifying these issues will stop future ingress and will increase longevity.
- Deteriorating and loose barge caps and pointing to the rear porch, which are producing gaps and we expect further failures causing ingress. Rebedding and repointing the ridge caps tiles will stop future ingress and will increase longevity.
- Evidence of numerous damaged, slipped roof tiles to the front porch roof valley, resulting from lack of tile clips being installed. Valley roof tiles have not been cut to leave 100mm to 150mm channels as per manufacturer’s instructions, if not rectified may lead to ingress. Information regarding installation of roof tile valley is shown above.
- Downpipe spreader, non compliant to SA HB39 refer 5.7.7 as shown. Spreaders are to discharge all roof water in the direction of flow avoiding discharging onto laps of roof tiles and flashings. Sarking is not installed to the lower roof and is required beneath downpipes on tiled roofs, noncompliant to NCC 3.5.1.2.
- Evidence of roof tiles out of position, this does not comply with manufacturer’s instructions. Pulling tiles down into the correct position will make it compliant, will stop future ingress and will increase longevity.
- Evidence of inadequate, non-professional installation of lead flashings to the front entrance, which has not been provided with a minimum 150mm of effective coverage and gaps are present. Rectifying this issue will stop future ingress and will increase longevity.
- Evidence of installation of lead flashings to the Dutch gable of the front entrance, which has not been provided with a minimum 150mm of effective coverage and gaps are present. Rectifying this issue will stop future ingress and will increase longevity.
- There is no evidence of sarking present to the main roof or front entrance. The pitch of the main roof is approximately 21.9 degrees, and the front entrance is approximately 22.7 degrees, as shown. The minimum roof pitch for this design of tile is 20-degree pitch without sarking and 15- degree with sarking.
