You will still need to go though your insurance as it everyone will take the points provided by your builder as fact. They inspected the property and they believe the work is satisfactory. The storm was a major event with wind driven rain and not likely to occur again for a number of years. Both points will remain factorial unless a more common rain event causes leaks. Until then for some reason both you and your insurance company are out of pocket and inconvenienced. For some context A work colleague just finished a house with over ground flooding due to what I consider a poor design of the driveway they all the water was intentionally diverted towards a drain beside the house rather than away from the house. The first rain event they were told the same thing “ big storm, lots of water”. Funny enough the second rain event a week later “ big storm lots of water”. Thanks for your feedback. Head of Construction replied my email below. Head of Construction replied my email below. "Please see below detail showing what we have constructed at your home. This is directly from Department of Fair Trading details showing we have completed the roof flashings correctly. To answer your question No, you will not have to contact your insurance every time you get a storm as it will not leak under normal storms. What we encountered recently was a rain cell that we have not seen in 30 years and homes that never leaked before leaked. The rain intensity was more than many houses were designed for."

I I was a betting person, I would take a punt on the actual profile of the sheet being “upside down” The image shows a high edge closest to the wall. I think the opposite is more likely to be the case. This would explain how “wind driven rain” could enter. Re: Builder denied the new home warranty for the leak on gar 32Feb 25, 2020 7:02 am westbourne the Australian standards clearly require the roof to be sealed against upwards wind driven rain. If Rawson Homes have omitted the foam sealing the roof does not these meet standards and is defective. The NSWDFT guide diagram is not the standards document and just indicates the basic construction method. Ask Rawson Homes to reference the correct standards documents and sections in their response, assuming they have ready access to these. If they don’t have professional access to the building standards then they have a much bigger problem! In the standards documents Rawson will find references to the sealing materials and pictures of compliant installation Including these on metal roofs. If you interpret and quote standards you need to actually reference them. Should be quick and easy for Rawson Homes to do this for you. If they have difficulty with this they can easily ask the HIA's technical manager for assistance. It’s unlikely an insurance company will approve a claim for your defective building works. They are on to this cost shifting game. Rawson Homes is either incompetent and does not understand Australian building standards or they are simply trying to bluff you, like they have done previously to many other customers to manage their costs and the maintain the top insurance rating they promote. A quick scan of product review’s Q&A indicates this behaviour is most likely to be the case. Don’t accept this rubbish from Rawson. Based on their responses you have shared, its likely all their other roofs have also omitted the required sealing foam and will also leak with wind driven rain. Wisdom homes will be liable to correct these defects and pay for the damage that occurs. I suggest Rawsons customers check their own roofs carefully for the missing weather seals that Rawson asserts is normal. Re: Builder denied the new home warranty for the leak on gar 33Feb 25, 2020 9:39 am They have now given you two bits of useful information. - They have now stated what their design is (or is meant to be) and its that of the default standards. - They have now stated it wont happen again in a normal rain event. (If it happens again its clearly their fault. ) What about hiring a third party inspector to compare your design vs that of the standards that they provided. If there is a deviation then you've got them. And you can send them a bill for the third party inspection too. Re: Builder denied the new home warranty for the leak on gar 34Feb 25, 2020 9:54 am Note Rawson Homes has not yet provided sufficient details of the AS 1562.1 2018 section 3.3.1 standards. If they check these standards they will confirm their work on this roof as well as their standard design is not compliant. The NSWDFT guide picture Rawson has provided is not the standards document above. I believe they are using this picture inappropriately and as a misleading bluffing tactic to try and avoid their responsibility to rectify many customers’ non compliant and defective works. Re: Builder denied the new home warranty for the leak on gar 35Feb 25, 2020 12:18 pm The National Construction Code (NCC) is a 3 part performance based legislated publication comprising the Building Code of Australia (Parts 1 & 2) and the Plumbing Code of Australia (Part 3). Being the primary document, the NCC has hierarchy over referenced Australian Standards. If the Australian Standards cannot meet a NCC minimum mandatory Performance Requirement, then a certified Performance Solution must be used to meet that requirement. The NCC Part 2 under Part 3.5.1 Sheet Roofing states: Appropriate Performance Requirements Where an alternative roof cladding is proposed as a Performance Solution to that described in Part 3.5.1, that proposal must comply with— (a) Performance Requirement P2.1.1; and (b) Performance Requirement P2.2.2; and (c) the relevant Performance Requirements determined in accordance with A2.2(3) and A2.4(3) as applicable. P2.1.1 Structural stability and resistance states: (a) A building or structure, during construction and use, with appropriate degrees of reliability, must— (i) perform adequately under all reasonably expected design actions; and (ii) withstand extreme or frequently repeated design actions; and (iii) be designed to sustain local damage, with the structural system as a whole remaining stable and not being damaged to an extent disproportionate to the original local damage; and (iv) avoid causing damage to other properties, by resisting the actions to which it may reasonably be expected to be subjected. (b) The actions to be considered to satisfy (a) include but are not limited to— (i) permanent actions (dead loads); and (ii) imposed actions (live loads arising from occupancy and use); and (iii) wind action; and (iv) earthquake action; and (v) snow action; and (vi) liquid pressure action; and (vii) ground water action; and (viii) rainwater action (including ponding action); and (x) differential movement; and (xi) time dependent effects (including creep and shrinkage); and (xii) thermal effects; and (xiii) ground movement caused by— (A) swelling, shrinkage or freezing of the subsoil; and (B) landslip or subsidence; and (C) siteworks associated with the building or structure; and (xiv) construction activity actions; and (xv) termite actions. P2.2.2 Weatherproofing states: A roof and external wall (including openings around windows and doors) must prevent the penetration of water that could cause— (a) unhealthy or dangerous conditions, or loss of amenity for occupants; and (b) undue dampness or deterioration of building elements.

The roof was not damage at all and the rain poured down from the roof like a shower. The leak is apparently due to construction design which cannot withstand a heavy thunder storm. Who should take the responsibility, Rawson builder or home owner? Should the leak and ceiling damage be take care by the builder under new home warranty? Re: Builder denied the new home warranty for the leak on gar 37Feb 26, 2020 9:50 am westbourne Rawson Homes is legally obligated to rectify their non compliant and therefore defective roof, and to fix all the damage it has caused. This is required on your house, as well as all other houses they have built covered by their warranty. Rawson have confirmed to you in writing the roof on your house is their standard design. Without the appropriate weather sealing their standard roof design is non compliant to Australian standards and the NCC and as such is defective. It’s likely Rawson’s other customers’ standard design roofs will also leak under heavy wind driven rain.
