Please can anyone tell me how long a run of roof guttering can be, between downpipes.(ie the recommended interval)
Thank you for your help.

As long as the guttering is sufficiently supported and there's a slight fall towards the downpipe then you can run them for quite a long way, more than you'd ever need to.
The problem lies more with the size of the roof in that a large roof will collect a huge amount of rain therefor overloading the gutter to make it spill over.
There is a 'recommended' length but i've seen huge building with one gutter and one downpipe, th difference was they were huge gutters and huge downpipes, at lot bigger than the small domestic ones.
See the link below to Marley, they are one of the biggest manufacturers of guttering and this is a calculation page to help you work out what you need.

It all depends how long your building is and what guttering you use.
Half round - is ok for an average house length.
Square - Is ok for a front and side of an average house.
Both will need two downpipes.
Deep flo - should go all way round house with one downpipe.
You will need to insure that there is a fall in your guttering.
Usually 1/8 - 1/4 inch per linear meter.
If you can be more specific about your type of house and what guttering you are using this would help.
Have fun

We recently got our gutters replaced (they were inefficient and got filled with seed pods from the tree in the yard which then would sprout little treelings inside the gutters and were very difficult to remove) and the company we used was great. Our house is small but they put our downspouts in every 42 feet and I believe they said that was recommended. For a bigger house, I would believe it isn't necessary to put them in that frequently.
Put in good gutters and WIDE downspouts and you will be problem-free!

It should be on one side of the gutter. The gutter should be installed at a slight angle, and where you see the gutter at the lower spot, this is where the downspout will go. If you put it on the opposite end, the downspout will serve no purpose.

When you hire someone to do this work, leave it up to them to specify for their warranty. Don't tell them, let them tell you in writing. All of these things are dependent upon several things that are too lengthy to write about, get several estimates.
