Im having a standing seam metal panel roof installed and I contracted the roofer to have a ridge vent installed.
Im concerned with high wind driven rain from hurricanes blowing in but the roofers all say that wont happen.
Also the roofer installing the roof was caught by surprise when I asked him how he would do the vent, he said he had to go over the contract because he was unaware there would be a ridge vent. He then mentioned that he would not be making a cut but would be opening 1" holes alternating frm side to side of ridge. Is that an accepted practice? Will that be enough to vent the attic? I was under the impression that the entire ridge would be cut 2-4ft from the ends. By the way its a gable roof, not sure about slope but not too steep, Id say about average.

I would be curious about the design of the ridge vent. Whether they are usinng a commercially available one, one produced by the roofing manufacturer, or trying to make it themselves.
Proper ventilation requires instake (usually eave soffit vents) and exhaust (ridge vent). You will never move more air than those vents permit.
The alternating holes at the ridge will essentially limit the total amount of free air space and air movement which can be achieved.

My $.02 worth. Have the roofer install a manufactured ridge vent. We had a standing seam roof installed last fall and our installers went the homemade route (2 1/2" holes every 4' on the north side of the ridge). But during this past week's heat wave, the attic is hitting 140-150 degrees. So now I'm looking at either installing powered gable fans or installing a real ridge vent.

There are many different ways in which it can be done but normally for residential jobs, the final appearance is really no different than a standard ridge cap, as can be seen on many photos on this site.
