One of my metal roofing bids includes using ice dam membrane on the entire roof deck. Is there any draw back to this? It sounds like a good idea to me.

It will eliminate any breathability through your roof deck. Therefore, I encourage making sure you have good attic ventilation beneath it.

I have attic ventilation but not sure if it's a 1 to 300 ratio. Since I live in an area that has no snow or ice dam issues, is the membrane that much better than a synthetic underlayment? Thanks
