Pergolas are almost always quite flat. It only slopes 1+' for the 26' length so very slight (2.3 degrees I think is what we calculated for cutting the tops of the posts).
This is supposed to be very strong polycarbonate (used for making skylights for many of the large supermarkets across Canada, including the Prairies) so hopefully it'll stand up to Vancouver's snowload.
It has 8 4x6 posts and is attached to the house. The main beams are 26' long and made from a laminate (nailed together) "sandwich of 12' & 14' (left) 3 @ 8' (middle) and 14' & 12' (right) 2x6s.
It's No.2 grade WRC so not bad. I lucked out and was able to order it through some guys at BCA for a great price. Altogether, the wood for the pergola was around $500+, but I ordered $734 worth (including $90 delivery) altogether for my other projects.
I plan to build my 10' x 3' x 8' tall bbq pergola next and then a 7' x 3' pergola cover for my patio swing.
Total cost for the project was $1500-1600, but that includes buying a used Bostitch 3.5" nail gun to speed up the process.
