malu asked:

The people who worked on the roof they closed eleven holes in the roof for roof-vent with shingles, and they installed vents afterwards.

Now the contractor says there is no problem in installing Vents and Drip edge after the roof work is done? Is he telling truth??

The bottom of the metal roof of my canopy carport has condensation on it in the mornings. How can I insulate the bottom side. A friend recommened to use close cell foam insulation that is sprayed on but it is expensive.
