Apart from slope assisted drainage, damage comes by way of negatively charged accumulated sediments and decaying organic matter interacting with metals which are positively charged. It would be a massive end cap leak to discharge the amount of water as described and it is remarkable if they were not able to fix this minor defect. If I was on site, I would first check the gutter slope and use a hose to run some water off the roof for visuals as there is a need to quickly drain the water from the spreader to the diagonally opposite downpipe. To achieve this, a good slope is required. A concentrated flow of water into a slotted gutter with the downpipe seven meters away and a corner in between is poor design. A downpipe was most probably not installed where the spreader discharges due to aesthetics but this can be worked around by hiding the downpipe. I was wondering what the downpipe size is, is it the same as the others? Amongst the many weird things that I have seen has been small downpipes fitted to small roof areas despite a larger roof area draining to that roof. I can't judge what area of upper roof drains to the spreader because I need to know where the gutter's high points are. The high points determine the roof area that slopes either side of the high point and the low point is where the downpipe is fitted. In any case, compliance does not guarantee good design. Builders not fitting temporary downpipes once the roof is on and also failing to slope the land away from the slab is potentially very damaging if you are on highly reactive soil. 3in1 Supadiverta.

Re: Gutters and downpipe requirements 12Apr 18, 2017 12:42 pm First few things I said to my Draftsman /architect was, want a really good drainage system and extra downpipes put in, 3_4 more than required, have seen way too many water problems due to inadequate downpipe numbers, often causes thousands and thousands of damage internally. Re: Gutters and downpipe requirements 13Aug 18, 2018 4:14 pm "For a tiled roof, the lower section shall be sarked a minimum width of 1800 mm, either side from the point of discharge, and extended down to the eaves gutter" refers to AS3500.2 - 2018. clause 3.4.5 What is the meaning of the above requirement? Re: Gutters and downpipe requirements 14Aug 18, 2018 7:18 pm It comes under AS/NZS 3500.3 Stormwater Drainage, not AS/NZS 3500.2 Do you know what sarking is? If there is a downpipe discharging water through a spreader from a higher roof area onto a lower tiled roof area, the lower section must be sarked a minimum of 1800mm either side of the point of discharge ( which is the spreader) and extend down to the eaves gutter in accordance with AS 2050. The sarking obviously has to extend to the gutter so that it legally discharges to an appropriate drain outside the roof space. 3in1 Supadiverta.

I can't see an alfresco downpipe indicated on the plan but I logically assume that there is one. Is there and if so, what size is it? Thanks so much for this very valuable guidance. Here is another shot from the floorplan. This shows the single downpipe to the alfresco Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Here the the whole upper level plan which I believe shows the roofline (15 degree pitch skillion roof) Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ The gutters seem to be retaining water. The overflow is at the end. We thought that silicone was required and when the roofing company came out to inspect they said they had to put more silicone around the endcap but it did nothing. This morning it wasn't raining. It the gutter was still dripping. I'm guessing this means the gutters are retaining water. I think I read that they are only deemed defective if they retain more than 10mm. Is that right? I'll check the size when I get home but guessing based on the alfresco roof catchment plus the abutting wall plus upper level catchment (not sure how that's determined for a skillion roof) that there should be more than one downpipe. I'm also concerned that temp downpipes were never installed during construction. We had a lot of rain and they didn't create any fall away from the slab around the house. A lot of water pooled around the slab. Is this cause for concern too? C U S T O M. C O R A L. B R O N T E. 43 http://forum.homeone.com.au/viewtopic.php?t=79581 Hi, sorry to bring up an old thread. Do your gutters still retain water? We noticed this one our gutters on the garage, similar set up to yours. Scares me what is going on upstairs which we can't see. Wanted to see if you've had any problem with this since. We are almost a year in and still chasing Coral.
