[GSBN] Curved Gutter

Thu May 2 23:06:49 UTC 2013

Hi 

Thanks for the replies.

We ended using an I beam which we could curve to the correct radius – it was very expensive – but other choices were not available to us.

Regards

Bohdan

For curved earth roofs we've used flexible perforated foundation drain line, which holds back the soil and allows the water to seep in.  It's worked quite well, and the same could be adapted as a gutter, without the perforations.

Here's a pic of the short straight segment technique in cut and soldered copper. Old school, pretty and nice for a long service life. Can't see it in this photo, but they peened the whole thing to make it look extra cool, which it definitely did. 

At one point when the copper price crashed it was the same cost as enameled steel I considered using it on our roof instead of steel. I calculated the amount of Cu leaching from a 1600± ft2 of it with 18" a year of rain and concluded that it was fine if it was adsorbing into soil but not if it was going directly into a freshwater aquatic ecosystem. For gutters only it's probably too little Cu to worry about unless you are filling an aquarium. By the time the HOA approved our project--a year later--Cu was 4x as expensive as steel. Glad I didn't use Cu, as it saves us $ on an armed guard to keep an eye on the roof...

Thanks for that.

There is an interesting building in the Grampians in Victoria – which has a curved roof – and the architect made up the gutter with short lengths of metal half round gutter.

So I couldn’t work out how to curve a metal gutter!

Hi Bodhan

We used lengths of plastic water pipe, split and popped over the edge of the roof.

We get plenty of rain - and the detail works great. See photo attached.
