I have 2 bids right now for a roofing job and they are very close in price. One of the contractors states that he will use “20” Galvanized metal in all valleys" and the other says “90 lb rolled roofing in all valleys”. It sounds like the metal is a better way to go but is it? Also, the guy with the 90lb rolled roofing states that he does a “double ridge”. Again, does this really matter?
I’m going to get a third quote since that’s what I see recommended here. I’m also adding 5 turbines since I have only flats now and not nearly enough ventilation in my attic. I have about 2200 sqft under roof and 7 flat vents which I don’t think is nearly enough. So, I’m going with 5 turbines and 2 flats with this next roof.
Thanks for any and all comments.
