I am replaceing a sttep wood shake roof. I live in Los angeles. I’m replacing with Certainteed Presidential shake. I got offers in a wide price range. Some offered plywood some offered OSB plywood and some offered CDX plywood. What are the cost differences and quality differences?
OSB is Oriented Strand Board. Cheaper than plywood but not as strong. Plywood comes in many different types. CDX is exterior grade. It is really ugly but since it will be covered by shingles, siding, etc it doesn’t matter what it looks like. CDX plywood is stronger than OSB but cost more.
Pay the extra money and get the better product. You don’t want to have to come back in a few years and rip up your roof to repair it just to save a few bucks today. The cost of repairs will far exceed any savings you realize.
