Roof decking, or sheathing, is the plywood base where shingles are attached. The deck acts as an important foundation for the underlayment and covering of your roof, as well as connects the roof to the frame of the house. Even though it’s not a visible component in the roofing system, unlike the often discussed shingles and gutters, the deck is a critical part of the entire structure. When damage to the roof sheathing goes unnoticed, it can lead to pervasive water issues and untimely roof repair calls.
What Does the Roof Decking Do?
Roof decking is a flat surface that is attached to the trusses and joists — your roof’s basic structure. The deck serves many purposes, including the following:
1. Supporting Shingles: A single shingle weighs up to 2.5lbs. Including the layers of asphalt shingles and tar paper or felt, the overall pressure your roof structure endures is more than you might initially expect. The decking provides the needed support for all of the weight so your roofing system won’t suddenly collapse.
2. Weather and Fire Protection: The decking helps in distributing the weight throughout the structure of your home, leading to better resistance against severe weather conditions. In addition, roofers often spray flame retardants on the decking as an extra line of defense.
3. Fewer Leaks: Similar to weather resistance, a sturdy roof sheathing provides protection from pervasive moisture issues and water leaks.
Maintaining the Plywood Decking
Moisture is the main enemy of wood materials, including your roof decking. When your plywood base is rotted, it can’t safely grip the nails attached to the roof structure, weakening its necessary support system. In addition, rotted wood absorbs water even more readily than dry, fresh wood. This means letting water compromise your attic and ceiling much quicker.
When getting a new roof, you should have your roof decking carefully inspected by roofing contractors. This can only be done when the old shingles have been completely removed. Although replacing damaged decking adds cost to a roofing project, it will significantly reduce the potential problems you may experience along the way.
