Why I Recommend Replacing Your Roof Deck with OSB
This photo shows a sample of delaminated plywood.

When it’s time to replace your roof, you have a decision to make regarding the decking. Will you keep what you have, or upgrade it? I recommend replacing your roof deck with OSB.

Roof decking – the material covering the rafters and covered with shingles or another roofing material – is the workhorse of your roof. It keeps out water, provides a surface for nailing and braces the entire roofing system against heavy winds.

To help your shingles last 50 years, you need a sturdy deck.

Muth & Company Roofing recommends that older 3/8-inch plywood roof decks be replaced with 7/16-inch OSB (oriented strand board) when it’s time to install new roofing in Columbus or other areas of Central Ohio. This is especially true if the attic is not properly ventilated, because the 3/8-inch plywood will delaminate and not provide a good surface for nailing (see picture).

Replacing 3/8-inch plywood will also help your home meet the IBHS FORTIFIED Home™ standards, which call for 7/16-inch OSB or plywood. OSB is far less expensive than plywood, and is the most frequent choice for roof decks. OSB is made from wood ground into thin wood strands that are mixed with wax and adhesive, and then hot-pressed. Approximately 50 layers of strands make one sheet of OSB. This has greater sheer strength. And it tends to hold nails better because there are no core voids or knots in the panels.

OSB won’t cup, warp, split or delaminate as easily as plywood. OSB is environmentally friendly because is it made of wood from small, fast-growing trees. That means less waste and better use of our natural resources.

We’re happy to help you make the best decisions for your home.
