Help! Skylight installation disaster

We hired a company to build a roof with sky lights on to our deck. They have framed it and attached the plywood to the roof, lined roof with the roof felt/paper and have currently started to install one of the skylights (we have 5). We have realized tonight that they have cut the holes too big! One inch too big length and width so that the flanges on the skylights hardly have anything to screw to because the skylight isn't wide enough to reach the rafters. Would should we do!!

You are probably looking at a normal skylight installation as seen from inside the house. From the inside, the skylight might look like it would fall right through the rough opening, but what you aren't seeing is the 3/4" thick extension jamb that must butt up to the interior of the skylight. It hasn't been installed yet. And they've likely left a little extra room around it so that it can be shimmed into place squarely.

There are usually 4 L brackets that will be screwed into the skylight and extend about 2" onto the roof sheeting so the skylight won't fall through the rough frame.

Did you ask the installation company about the apparent mistake?
