1 Many of the houses had OSB sheathing Material, usually plywood or oriented strand board (OSB), but sometimes wooden boards, installed on the exterior of wall studs, rafters, or roof trusses; siding or roofing installed on the sheathingâsometimes over strapping to create a rainscreen.
You are right on both counts DAO1, OSB is cheaper, but not as moisture stable as plywood. Looks like they are using maybe 30 to 40% OSB, strictly as a cost savings. If they were building top quality, they would be using Advent-Tec T&G roof sheathing, which is about twice the cost of OSB and 25% more than good CDX.lywood grasps the nails holding flashing, the finished roofing like asphalt shingles, or the like, better, especially long-term, than OSB which tends to soften more quickly with moisture cycles over the years.
