Findings & Recommendations In Stafford Heights Roof Inspection

  • Water ingress is event related due to the recent weather events. Upstairs living area, including kitchen have suffered water ingress resulting in damage to the internal ceiling linings. This may be more extensive on the upper side of the ceilings.
  • Evidence of a previous repair using Wetseal to the asbestos sheets. The roof sheets are heavily reliant on Wetseal which is showing signs of deterioration, and a build-up of Wetseal in the pan of the sheets which is blocking the flow of water resulting in the anti-capillary feature of the sheet lap has been compromised. Also, potential to trap in water and cause ingress. Wetseal is only a temporary repair and tends to trap moisture into the joints increasing the risk of ingress. Rectifying these issues will stop future ingress and will increase longevity.
  • Evidence of insufficient roof screws which have been installed in the solar panel brackets, neoprene washers have not been installed in between the fastener and bracket which will lead to ingress. Also, evidence of previous repairs to the solar panel brackets using silicone, which has no longevity and breaks down under the sun’s UV rays. Rectifying these issues will stop future ingress and will increase longevity.
  • Evidence of Dektite which is showing signs of deterioration, lapped onto the roof against the flow of water and is heavily reliant on silicone, which has no longevity and breaks down under the sun’s UV rays, also potential to trap in water and cause ingress. Rectifying this issue will stop future ingress and will increase longevity.
  • Evidence of cracks and splits all along the asbestos ridge capping, this is a possible cause of ingress, previous repair to the asbestos ridge capping using silicone is evident, which has no longevity and breaks down under the sun’s UV rays. Rectifying these issues will stop future ingress and will increase longevity.
  • Evidence of previous repair to the asbestos ridge capping using waterproof tape, which is only a temporary repair and has no longevity. Rectifying this issue will stop future ingress and will increase longevity.
  • Evidence of pipe penetrations which have been previously repaired using Wetseal, lapped against the flow of water, are heavily reliant on silicone and are showing signs of deterioration, also potential to trap in water and cause ingress. Rectifying these issues will stop future ingress and will increase longevity.
  • Evidence of skylight with debris build-up behind the frame, lapped onto the roof against the flow of water, showing signs of deterioration with potential to trap in water and cause ingress. Rectifying these issues will stop future ingress and will increase longevity.
  • Evidence that lead Dektite is heavily reliant on silicone, which has no longevity and has potential to trap in water and cause ingress.
  • Evidence of skylight sheet showing signs of deterioration with potential to cause water ingress. Rectifying this issue will stop future ingress and will increase longevity.
  • Evidence of previous repair using a roof sheet lapped onto the roof against the flow of water, is showing signs of deterioration with potential to trap in water and cause ingress. Rectifying this issue will stop future ingress and will increase longevity.
  • Evidence that the whirlybird is lapped onto the roof against the flow of water and is heavily reliant on silicone, which has no longevity and breaks down under the sun’s UV rays, also potential to trap in water and cause ingress. Also, evidence of slight hail damage. Rectifying these issues will stop future ingress and will increase longevity.
  • Roof fasteners have reached the end of their serviceable lifespan. They are heavily corroded and require replacement. Also, evidence of missing fasteners with redundant holes. Rectifying these issues will stop future ingress and will increase longevity.
