Is OSB OK for roof sheathing?
Using OSB For Roof Sheathing
You can use an OSB body for the exterior roof sheathing on your home. The OSB material is different from plywood. But it has become increasingly popular for roofers. It’s all thanks to how well the OSB material can stay strong and secure for long-term use.
Which side of OSB goes up on roof?
OSB roof panels should always be installed with the grade stamp facing into the attic and the screened surface (with the nail guide lines) facing up. When the grade stamp is covered by roofing, the building inspector will not be able to confirm that the correct OSB roofing panel was used.
Can you use half inch plywood on a roof?
Standard roof sheathing thickness is ½” to ⅝” thick. If you are using OSB for your roof deck, then ⅝” is the recommended thickness. For plywood, which is slightly stronger than strand board, ½” thick is appropriate.
Is CDX or OSB better?
Although some people will ultimately choose CDX, many experts argue that OSB is better overall for roofing. OSB is far less likely to expand and contract when exposed to humidity and moisture, even though it will take longer to dry. With wrapping, though, it can withstand the elements without issue.
What does CDX stand for?
The letter “X” in CDX refers to the type of glue used in the factory to bond the plywood veneers. Some mistakenly think the “X” stands for “exterior”—which is not true. The letter “X” stands for exposure, which means the plywood is tough enough to withstand a little moisture—but for only a short time.
Why is CDX cheaper than OSB?
Oriented strand board (OSB) combines wood chips, glue, and resin into the shape of a sheet of plywood and bakes them together. What is this? It is often less expensive than CDX plywood because this manufacturing process doesn’t require the same costly veneers found on the front and back of CDX plywood.
What is the best plywood to use for roofing?
What is the Best Plywood for Roofing? 5/8-inch plywood is the most common choice for roofing with 24-inch rafter spacing.
