Downpipe angle vs roof

[paro]

Hi All - As part of my work I was hoping to replace the pvc gutter with some nicer looking galvanised steel. The lean to roof is 38 degrees so a non standard size. I was hoping to find some kind of simple adjustable bend but this doesn't seem to be a thing. My next idea was to step it out slightly and then run it down the wall using a standard angle, however this will not look great as it will be at a different angle to the roof. In all honestly I am probably the only person that will ever see or notice this given that it's kind of hidden away. I thought I should ask if anyone was aware of any options for an adjustable bend. I did speak to someone from a reseller who said there are companies that will make custom ones but this will propbably cost a fortune and I am trying to stop myself doing stuff like that. 

 

The final downpipe will be fixed to the return wall on the extension. 

 

Thanks, Paul

We solved a similar problem in a stuff-it-can't-find-the-right-product-way  (wrong angle in the available standard stock)

Not exactly the same issue as yours - but close..... Like this - a few holes drilled in the bottom. Take the boot off, flush out the leaves bingo.

Thanks I needed that with all this build stuff at the moment

All part of the service, sir.

No help in an existing building, but this is just one of the many reasons I think all new roofs should be built at a 45 degree angle.

I'd be gluing a 45 deg bend to the down pipe and then firing up a hot air gun and heating the downpipe just after the bend to make it form to the required 38 deg angle - you are never gonna see it from ground level and the water is going to want to flow along the bottom of the down pipe anyway

Alternatively - if you get some solvent weld adhesive and it melts the down pipe fitting you might be able to pie cut a fitting and then solvent weld it??

Can't two 45 bends be joined and rotated to give the required angle with a slight side step.

Or even one 90 deg to the right and then another 90 deg that can set the angle to whatever is required - good plan

 

it would have to be tight to the wall to stop it being forced apart - depends on how much water is expected?

Perhaps a self tapping screw through the joint on the top would be enough to stop it coming apart? Or a bit of PU adhesive like Tigerseal.

When my neighbour replaced the gutters on her single garage (they are joined to my double length garage) the “handy man” joined the two sections with a wood screw because the gutters were different profiles as well as wood screws holding the gutter to down-pipe join

 

I didn’t know this till later.

 

My garage wall was showing signs of damp so I asked her if I could pop into her garden and check it out.

 

I found this in her down pipe

 

I’m not keen on screws thro plastic pipes as they can catch stuff and lead to blockages…..

Thanks all. I'm going to try the joining angles together to make it work.
