 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. You're very welcome. Good luck with that project.
