Gluing the roof to the shed is one of the more difficult parts of the project. The Plastruct Weldene cement will give you a little bit of working time to get everything properly aligned, but once it sets the position will be final.
Do a dry fit first. Check the that the angles along the side walls are at the right angle and that the roof itself as enough of a bend. You can also mark the underside of the roof to help keep the overhangs on all four sides even.
When ready, apply cement to all of the brackets. Hold the roof in place until dry. The roof may want to lift up from the tension on the support at the peak. Once the glue sets, everything will hold.
All that is left is adding the final roof details!
