For guttering I always use one of two different methods depending on what I am doing. The first and easiest is the use of umbrella ribs. Can't get much simpler than that. If you haven't got an old one then pop into a charity shop and lash out. Make sure you get one with the correct section ribs. You will know as soon as you look at them.
The second method, giving you more choice of size, is to use a thin card. Filing cards are great, easily purchased from Smiths or the Office shop and they are of decent quality card and also useful for much exterior detailing on buildings and other projects, things like window and door lintels and sills for example, or, as in this case, guttering. Using a sharp knife and score a 2mm in from one edge of your card and then cut though the card 2mm from that. When creased along the score this will give you a 'V' shaped section. If this isn't what you want then the same piece of card and score the first line as before then score another 2mm from that and finally cut through the card 2mm from the last score. This will give you a very nice 'U' section gutter in 4mm when creased along the score lines. All you have to do is then cut to length. If your card isn't long enough then make two sections and join together with a small length, about 4-5mm of the same section. When coloured this will look just like the real thing.
Takes time to explain but about two minutes to make for each length, if that.
When you have your guttering then it depends on the roof overhang as to how to fasten it to the building. If the overhang is very small then one side of the gutter can go directly on the side of the wall but if the overhang is larger then you will need two or three spacers glued on the wall first to bring the guttering into the correct position.
Collector boxes for the guttering are just as easily made from the same card. Mark out the front and ends of the box on your card in one length and cut out. Then score vertically where the ends meet the front of the box. When folded you now have a three sided box which is glued to the wall in the appropriate place.
