Rafter tails: protecting roof sheathing from water damage
We’re building in central Virignia, Zone 4. We are going to have exposed rafter tails. I’m sistering 2×6 tails onto 2×8 rafters–much like the attached detail I found on the web. I’m concerned about water getting between the T & G and the sheathing and causing problems beginning with the underside of the sheathing. Should I be wrapping the underside of the sheathing before I put it down and if so, what should I be using? House wrap, something like Grace Ice & Water Shield, drainable housewrap? I’d appreciate any thoughts.
I’m note sure if it’s applicable, but we are just venting with gable vents, so negotiating soffit venting is not an issue.
