The Roof Deck: What Exactly Is It?
When professionals in the roofing industry refer to the term "decking" or "sheathing," they are discussing the layer of plywood or other wood material that lies beneath the shingles. The roof deck serves as the backbone of your roofing system, held up by the framing of your roof. It is an indispensable component that is often overlooked by roofing companies that are more focused on cutting costs than ensuring quality.
Why a Robust Roof Deck Matters
Installing new shingles on a deteriorating or damaged roof deck is akin to building a house on a shaky foundation. The shingles may become compromised, reducing the longevity of your new roof. A weakened roof deck can lead to pooling of water in sagging areas, eventually causing leaks. Moreover, if the roof deck is not in optimal condition, the nails used for installing the shingles may not hold securely, making your roof susceptible to wind damage.

The Role of Roof Decking in Ventilation
Proper ventilation is crucial for the longevity of your roofing system. A sagging roof deck between rafters is often indicative of inadequate ventilation. Poor ventilation can lead to a cycle of heat and moisture accumulation, weakening the plywood decking over time. This results in a roof that not only appears wavy but also struggles under the weight of snow. At Equity Roofing, we emphasize the importance of discussing ventilation options with your roofing contractor to ensure the longevity of your new roof.
Roof Decking in Older Homes
If your home was constructed more than three decades ago, it's likely that traditional lumber boards were used for the roof deck. While these boards may still be in good condition, they often have large gaps that can cause issues during the installation of new shingles. In such cases, it becomes necessary to add a layer of plywood or OSB decking on top of the existing boards. If you're transitioning from a slate or wood shake roof to shingles, installing a new roof deck should be a priority.
Key Questions to Ask Your Contractor
When you're considering a roof replacement, it's crucial to inquire about the condition of your roof deck. Make sure your contractor inspects the sheeting thoroughly and replaces any sections showing visible damage. If you have an accessible attic space, ask your contractor to inspect the roof deck from the inside as well. This ensures that any required decking is included in the initial estimate.
