 So what you would want to do is install a ridge vent down the peak of the roof from end to end to open that up and then couple that with soffit vents at the overhang so that 24-7, 365, you would have a washer of air in the soffit vents under the roof sheathing and out at that peak, at that ridge, which will keep it very even temperature, keep it at that ambient temperature, which makes the shingles last as long as possible. If it's done well, you could get a roof that lasts you 25, 30 years easy. Okay. Well, thank you.
