There needs to be a pitch in order to allow the water to runoff (come rain or snow).
*I need to install lower, too. After studying the drawings and parts lists, I plan to order and install at something under 100 inches. Although it will void the warranty, the support posts can be shortened to keep the pitch within the recommended range. Shortening the posts would lower the gutter edge of the awning, but when you’re installing in unchangeable real life conditions, voiding the warranty and having a lower gutter edge may be acceptable compromises. The posts are aluminum extrusions that will cut nicely with any chop saw with a carbide-tipped blade. If you’re not comfortable doing that yourself, most handymen or contractors should be able to help you out. 90 inches is 7’6″, and a 13 degree pitch 10′ from the wall will result in a gutter height of about 5’2″. If you’re in the tropics and don’t have to worry about snow load, you could probably flatten the angle to something less than 13 degrees to raise the height of the gutter edge. You will have already voided the warranty anyway, so what the heck? An 8.5 degree slope would make the gutter height 6’0″. 10 degrees makes gutter height 5’8-13/16″. A bigger problem for me is that I can’t use the entire 10 feet the awning extends from the wall, so I have to shorten all the ribs and polycarbonate panels. After looking at all the specs, this, too, seems do-able, once I accept that it will void the warranty.
*I would think this is because of the load rating, if you have a flat pitch on the roof and get any type of a snow load, than you might run into a risk of the patio cover collapsing. And with rain fall, the rain might want to run towards the house, plus it would put more weight on the wall mount.
