Help, Joining Poly Carb roof opposite way round?

[sean oc]

Dont laugh at my poor paint skills haha

I have a slanted lean to which is a large area, so the poly car sheets dont reach the full length
so the join will be half way down the slant so i want to know to to join it? thats water tight as a car will be stored under it,

Ive seen the joins and T bar connectors which work great if the poly carb sheer goes the full length and join along ways.

Whats the best way?

Or am i best getting the corrugated effect ones and overlap them

Hope that makes sense. Cheers

What is the length and width of that roof? Are the existing timbers where you've drawn those lines?

I'd be using corrugated something with overlaps rather than trying to join twinwall (presumably what you've got)- all that jointing kit gets really pricey for a garage roof
