Hi can anyone help. I want to fit a canopy with a slope to the front of my house, spanning over the front door and a bay window. It will need to be about 6.5 metres long. The bay window has a flat roof and I need the under side of the canopy to marry up with it. i'm not sure which style of bracket would give the best support. If I used 100 x 75 timber do you think it will be overkill, I do want it to look substantial.
