I wonder if I'll get any response to this one?

My daughter wishes to have the 1.5m wide passageway between her house
wall and single storey garage covered in with some clear corrugated
PVC.

The problem is that the passageway slopes down and the garage has a
pent roof sloping down to the rear also. I wish to shed rain onto the
garage roof to avoid extra guttering.

So do I fix a 100x50mm timber to the house and level with the
brickwork and fix a similar piece of timber set off from the garage
wall and kept parallel with the timber on the house by having a
sloping up stand with allowance for cross fall.

or

Fix the timber on the house but sloping with the slope of the garage
roof

or

Have the house side timber parallel with the brickwork and the garage
timber following the slope of the garage roof and force the corrugated
PVC sheets into a helical skew

Can't understand that. Try a sketch with a link to the sketch.

Ditto.

I would fix the timber on the house but sloping with the slope of the
garage roof. With an additional slope to the garage roof for water
discharge.

It would look silly otherwise.

Either way, its a recipe for disaster this sheeting tends to go brittle and
crack a lot after a few years, add some wind or strong draught and its gone.

How long inns the walkway?
I've seen kind of straight awnings and some neoprene sheet fitted at one or
both ends where the thing is skewed before. Looks a bit rubbish though, I
have to say.
Maybe buy her an umbrella forChristmas?

Depends on the sheeting and environment. I did have some standard Wickes
clear corrugated over a hay store and this only lasted a few years (but
small branches used to fall on it from large nearby trees, and it saw a
lot of wind). I have just replaced it with industrial/farming grade
fibreglass which should last much longer.

I certainly would not try to install it twisted. In my case, it drained
on to a pitched roof sloping towards the "corridor" so the supporting
purlins were horizontal. In your case I would incline towards tilted
purlins assuming the angle is not too large.

Yes this is the conclusion I was coming to.

I have the clear PVC corrugated over a lean to conservatory, the first
sheets lasted over 30 years till I replaced them 2 years ago, new ones
seem fine.

I have used both corrugated and twin wall polycarbonate for our
temporary shed thingy for many years. The polycarbonate is much better -
stronger, less noisy. I assume insulation isn't important?

One advantage of the corrugated is that you can overlap the joints. You
can do that with polycarbonate, too, but it looks v odd.

Yes and if there is not much fall you can overlap two corrugations,
else a small obstruction will cause water to back up enough to seep
past the overlap.

It's also very cheap.

Beyond a certain point it is probably less hassle to fit the extra
guttering.

Less need to follow the profile of the garage roof precisely and no
problems with rain water splashing back into the passage.

and no one wants rain water in their back passage that's what Bidet's are for. :-)

You can get joining strips

It also looks cheap. Twin walled polycarbonate is strong and resistant
to wind damage.

As Jonathan has said you can get jointing strips.

Except it requires guttering, brackets and pipes, assuming there you can
use the garage drainage.

problems with rain water splashing back into the passage.

There is that, but I would follow the slope of the garage to reduce the
open air gap and the effect from wind in the passage way.

This is a temporary cover until the kids grow up, after which garage
will be demolished for an extension.
