I wan't to construct a carport between our house and nextdoor, and will be attached to both walls rather than on posts. And it needs to be clear roofed (corrugated PVC is fine) as it's gonna cover our bathroom and kitchen.
And the houses aren't parallel to each other - if the carport is around 4.0m long, it'll be about 15-20cm narrower at the back...
Logic says the slope will run from front to back, but how can I fix the last row of roofing sheets when it's attached to a wall? The other option is to have it slope from one side to the other and attach a square section 'gutter' to one wall.
Any ideas?

a suggestion is how about fitting the run along the wall first then the second one out but slide it under the wall one and the third from the wall so the only sheet not fully secured is the second one but it is trapped full length of both sides and secured at both ends
also by sliding the sheet in it should flex to allow for missalignment
hope you can understand the gibberish i have just written and that it is of help to you

One way I've seen this done with flat rooves is to use a J section square gutter supported underneath by a 2x4 bolted to the house wall, at a slight cant so it drains from one end to the other, and the back end of the roof draining into that. The last one I saw was made from lead, but that's obscenely expensive, so the plastic ones work well, sealed in at the top with tarpaper and mastic sealant.
Bit like this in x-section

Where the left side is the house, the gutter attaches to it and is held up by the 2x4, and the roof drains in and is sealed inside of the gutter lip. Requires an extra brace across the back of the garage to hold the roof up but it's an option, then seal the corrugated in with that wiggly foam stuff that's meant for it or use a can of expandy-spray-foam

That's the sort of thing I've envisaged for a side to side slope phila.
Just need to find a suitable section of guttering to work with...

Our local builder's merchants used to do it for the sides of big buildings. It was grey PVC about 7-8mm thick, fairly heavy duty and uninspiring stuff, but it's designed to last for ages and is big enough it takes a good while to fill up with leaves and curse word.

Any 1/2 round gutter should be fine as long as you bracket it every 750mm
I wouldnt worry about slope on the gutter itself, the weight of water along its length will force it down the downpipe and leave a small few mm of fluid in there to stop crud sticking too bad.
I'd slope it slightly from side to side (offset by 100mm absolute MAXimum) and bead it with silicone (look for something called CT1, its the absolute dogs balderdash - impervious to EVERYTHING, sticks to EVERYTHING and can be used underwater!)
a 4m length of gutter is less than a tenner, brackets maybe another tenner for the lot, CT1 about a tenner a tube - job done!
