Browse Forums Building A New House 1 Nov 28, 2014 10:58 am Hi everyone! This is my first post! Would love to hear any feedback! Thanks! (is that enough exclamation points?) I have always noticed that when designing a wall/roof connection, people act like placing the gutter directly above the wall (as opposed to completely external and outside the finished wall surface) is one of the seven deadly sins. The fear behind this is clearly that the gutters will malfunction and leak rainwater into the wall structure. However, the issue with having the gutters external is that if you are building on boundaries, you have to 'skinny-up' the entire floor plan in order to accommodate gutters on both sides. Furthermore, I prefer to 'hide' the gutters behind the wall so they don't sit proud on the facade. I imagine the best solution is to use flashing, or sarking, or both, to create a moisture-proof barrier between the underside of the gutter and the wall itself. I wonder if there is a proprietary product designed specifically for this situation. I would love to hear opinions, experiences that have suceeded/failed etc. Thanks everyone! Re: Gutters directly above the wall - ill-advised or do-able 2Nov 28, 2014 12:03 pm gutters hidden behind the wall are called 'box gutters' Very common, although project builders (at least here in WA) prefer not to touch them. Typically here they will locate a gutter on-top of a wall - PM me your email if you would like me to send you some standard details. Box gutters are typically custom made pressed zincalume or colorbond, and can sit over a plywood gutter board or trimdeck/spandek support sheet. You can install overflows at a height lower than the height where water would flow into building. As long as the gutter is designed to handle 1/100 year (from memory?) rainfall event, are installed properly and you keep them clear of leaves and rubbish - you should have no issues. The building code has requirements related to these, so your designer/draftee should have it covered. Only horror stories I have heard are related to downpipes being blocked by water bottles and plastic - hail can also cause major issues - but when they do overflow, it is generally pretty catastrophic Small footprint in Eliza Ponds, Spearwood WA Re: Gutters directly above the wall - ill-advised or do-able 3Nov 30, 2014 9:14 am Thanks buddy. By overflows do you just mean cylindrical 'pipes' oriented horizontally? I'd love to see those details if you wouldn't mind. Re: Gutters directly above the wall - ill-advised or do-able 4Nov 30, 2014 9:45 am Pat its common practice where you have a zero boundary for the gutters to sit on top of the bricks. It just means a flashing comes down from behind the fascia across the top of the bricks and down the face of the top brick slightly. These are custom bent and supplied by the roof company. Dont stress if the gutter is on and the flashing is yet to be fitted, its an easy process to remove the gutter, fit the flashing and put back together. Have look at your house plans and you will probably find that brick articulation joint has been missed.
