lencolad Posted November 1, 2013 Posted November 1, 2013 (edited) Here's a challenge - how could a gutter be formed on a steel roof that has a gently curved lip ? Sheets have flat surface (not corry). Polypipe ? Is there a commercial option ? Edited November 1, 2013 by lencolad
lencolad Posted November 3, 2013 Author Posted November 3, 2013 I've worked out a way to do it now, but the flashing and downpipes would be a further issue so it's back to plain straight roof edge for a bit of sanity ....
MrHorsepower Posted November 3, 2013 Posted November 3, 2013 I've worked out a way to do it now, but the flashing and downpipes would be a further issue so it's back to plain straight roof edge for a bit of sanity .... Hold on ...you dont get away that easy you have piqued my interest and now you shut it down...Always interested in different builds (we are doing one ourselves now structural steel extension clad with Fielders Finesse, parapet/flat roof) Show us some pics.....Michael. 1
lencolad Posted November 3, 2013 Author Posted November 3, 2013 The roof is still in my head so no pics .... Plans are done and walls are up - the plans can be changed of course. The roof sheets are 'freezer panel' (200 mm thick colorbond/polystyrene/colorbond sandwich). Stratco can do curved flashing and guttering (for some not-cheap meter rate I guess) - http://stratco.com.au/products/flashings/types/curved_flashings/curved_flashings.asp - or else there's the old 'many 25 mm holes in polypipe slit down the middle and pushed onto the sheet lip' approach. Roof in plan view is a simple rectangle so the edge could be done as 4 arcs instead of a continuous curve but the downpipe would necessarily have to be in the middle of each edge (because it would be lowest in the middle). The downpipe could be elbowed to the 'corners' of course but I don't like elbows in downpipes if they can be avoided. Spatial geometry is fun. Simple building is fun too. All I've done for the last 2 years is work and build, so a curved roof edge means that holiday would be even further away. I've thought of recessing the gutter into the roof sheet but once again, simple is good. The house is a bit weird but then so am I. Humungous amounts of mass surrounded by plenty of insulation should equal thermal stability at 33.5° S latitude. Won't need much heating and no cooling.
lencolad Posted November 3, 2013 Author Posted November 3, 2013 (edited) I thought my roof was strange but then saw this made of old 747 wings and sacks of cash - http://www.houzz.com/ideabooks/19325945?utm_source=Houzz&utm_campaign=u380&utm_medium=email&utm_content=gallery0 Pilots have been told to not report this house as a crashed aircraft.

LogicprObe Posted November 3, 2013 Posted November 3, 2013 I used to work at Stratco, we used to make curved flahings and gutters all the time. The important thing is to get your radius right! when giving them the job Do they curve them when they are made or roll them later?
Capone Posted November 3, 2013 Posted November 3, 2013 All curved gutters are hand made by flat sheet metal by tradesman, they use colourbond steel or galv or zinc They can use a template given to them by the customer, or use a given radius. they are labour intensive, so the cost 1
LogicprObe Posted November 3, 2013 Posted November 3, 2013 Having worked on roll forming machines as a young bloke...........a good fitter could adjust a certain amount of gentle curves. You'd probably want a dedicated machine though................because you can waste a lot of steel getting them straight again!

Yes you are right, the roll formers can be adjusted to curve the gutters to a small radius.But to get the radius right, they would waste a lot of material to get it right 1
