How do you hang guttering from corrugated metal roof?

[jake118822]

I want to put up guttering around the sheds in my garden to collect rainwater to go into IBSc.

The shed roofs are 3m in length but the corrugated metal roof overhangs by about 30cm so there's no fascia to screw the guttering clips into. 

Does anyone know of a way to attach guttering to corrugated metal roofs so that they have a fall on them?

The photos attached show 1 shed that I want to put guttering on and 1 shed that I want to replace the "dodgy job" the previous owner had done. 

All have the issue of corrugated iron roofs but no facia.

Good Morning @jake118822 

Welcome to the coommunity, hopefully you will find the anser in here

No Facia, yeah I have that problem on my pool deck (Which I built so the fault is mine lol) 

Easy solution I hope for you. Can you see where the support beams of the roof come out? If you can you can bolt/attach lengths of timber to extend the beam out and then install a facia on the end and attach the gutter to it. Once we have some pics we may be able to suggest some other ideas.

If there is no battens or trusses to support the tin roofs you could potentially "fake it" by installing short lengths (25cm ish) under the edge and screw them to the corrorgated roof from the high points of the sheet (in two places so they lock in place). That way you will make the edge ridged and have a place to attach a facia to.

The gutter itself needs to have a slight fall towards the downpipe area is something to keep in mind once you have a new facia of some kind.

Hi @jake118822 ,

Only thing I can think of right now is to pop rivet some galavanised angle to the gutter's back, then attach that under the end of the corrugated roofing. (The steel angle would act like a small facia.)

Then add some normal gutter brackets to support it.  You could build in end to end fall when attaching the angle to the gutter.

Possibly suitable angle:-

Hello @jake118822 

Thanks for sharing your question about how to hang a gutter on a corrugated metal roof.

It's great that you've received excellent advice from @Dave-1 and @TedBear. I'm in total agreement with their recommendations, just to add to the solutions offered, I suggest using Carinya 20 x 200 x 2mm Flat Make-A-Bracket - single. This bracket can be bent to almost any angle and is strong enough to hold a fair amount of weight. 

When used as a set, it should be able to hold the facia and your gutter with relative ease.

Please make sure to use personal protection such as gloves, goggles and a mask when working on your project.

If you have any other questions we can help with, please let us know.
