What Is a Roof Deck?

Tuesday, June 9th, 2020 by Michael Fortenberry


Once you’ve found a reliable residential roofing company to handle your roof replacement, you’re likely to come across the term “roof decking.” A roof deck, also known as roof sheathing, is an important part of any roofing system. This is most often built with long planks of plywood and it’s where the underlayment, moisture barrier and the actual shingles are often nailed to.

Understanding your roof deck and the role it plays in keeping your roof in good shape is helpful in ensuring your roof lasts for as long as possible. Here are a few important things to know about your roof deck as explained by our experts at Fortenberry Roofing.

Types of Roofing Decks

Your residential roofing contractor can install one of many types of decks depending on what your roof needs. Decks can be tongue and groove, where one plank has a “tongue” on one edge and a “groove” on the other edge. This makes attaching them next to each other easier and quicker. The most common, however, is plywood sheathing, where planks of 4’ by 8’ plywood are laid down on the roof structure.

Roof Deck Maintenance

Like any other part of the roof, it’s important to include the deck in your regular maintenance inspections. The roof deck is protected from moisture and water by the shingles and the underlayment, but problems can still occur and cause damage.

Replacing a Deck

A roof replacement doesn’t necessarily entail a replacement of the deck although sometimes it is needed. A roofing professional will typically inspect the deck and its support structures to determine if it needs to be replaced. This is usually done before new shingles are installed.
