How do they attach it to the roof? Nails or screws? The ones that
were nailed down here in Florida came off the roofs easily during the
hurricanes. Do you have enough openings in the soffit to allow for
good air flow?

Not only a good Q but a critical one!

If you want to be sure you need to do some legwork and research so you
can talk to them with ammo. You need to calculate your roof area and
existing vent opening space. Read this.

Then go the GAF/Cobra site for additional info.

Then when you talk to roofer you can ask if it includes upping (if
necessary) the vents. If not, you have yourself a roofer who would have
done an inadequate install had you not got educated. OK, you may catch
him and he'll up the bill for additional venting but what else are they
messing up on that you don't know about?
