They're not really tiles though, are they...
low pitch roof

Depends what your interpretation of a tile is i suppose
The reason I wanted that shallow angle was to continue the line of a cantilevered canopy I currently have, and planned to reattach.
But I'm not going to be able to reattach it, as the support members are too deep. I might end up with a shorter one, which won't have such deep supports, but the slope will be the same, however having thought about what we'll be able to see from the garden I'm not as worried about the pitch of the roof matching that of the canopy as I once was.

Of what?
I don't quite understand the above. Do you want to join the roof to the cantilevered canopy?
Top sketch shows what I currently have. The canopy has a pitch of 10°
The bottom one shows what I wanted to achieve - I imagined that provided there was a way to stop water running up the underside of the lowest ones that the tiles would overlap the canopy as shown, but I never got as far as finding out if that would be the way to do it.
As I said - it was a purely aesthetic desire - I just thought it would look better if the canopy and the roof had the same pitch, but having realised that we wouldn't spend much time standing in the driveway admiring the consistency of line, I'm not so bothered now.
I think that I would still want the bottom tiles to overlap the canopy though.

The canopy sheets are thin - it's not that multi-wall polycarbonate stuff...
I know I have them on my property and I was told they are very strong fibreglass sheet unless yours is difference, maybe give them a ring and they may have some idea, maybe a metal profile self-tap to the of the brackets the same way the sheets are fitted.
I have worked on many vast commercial buildings with a roof slope less than 10 degrees. (Cannot remember exactly). Many of these used profiled aluminium sheets which came in lengths over 6m. Not very handsome, but keep the rain out. Just take a look at some recent warehouse units on an industrial estate.
Reasonable alternative is to board the roof and lay EPDM rubber sheet. I am not sure of the maximum slope the adhesive will hold the sheet down, but it may be an answer.

You can try looking at Dupont Tyvek. This is available from most good builders merchants. Take a look at their details on line they have the all important BBA certificate showing how to detail a roof membrane below minimum pitch using 2 layers with a good lap between sheets.
Doing it this way keeps the construction simple, allows the roof structure to breathe and keeps the roof water tight.
For added peace of mind you could lay 9mm marine ply down on top of your rafters, then your roof membranes, battens running down the slope of the roof then counter battens accross for your tiles to fix to.

Thanks!
there is a new system from Permavent called the easy roof system that will put all natural slates down to a pitch as low as 12.5degreesHi i have been told i have a low pitch roof and have the wrong tiles on it for that pitch, could you tell me what sort of tiles in need.
Thanks
