There’s a lot more to your roof than you think. While shingles are the most visible from the ground level, several layers of materials and components comprise your roofing system’s totality. Much like roof sheathing, roof decking is one of the most important pieces of the puzzle.
Homeowners may not understand everything about their roof—and that’s okay. Adam Vaillancourt Roofing is here to help you understand the importance of roof decking and its role in maintaining structural integrity and protection against the elements.
What is Roof Decking?
Roof decking is the foundational layer of material responsible for maintaining the roof’s structural integrity and load-supporting capabilities. Roof sheathing can be observed as a flat, level surface to which other roofing materials are applied.
Not only does roof decking create a rigid and stable platform for roofers to work on, but it also plays a key role in protecting against adverse elements and improving insulation. Its structural role prevents sagging or collapsing, which could result in costly repairs or a complete replacement of the roof itself.
A key function of any roof is protection against the elements. Roof decking serves as a barrier between things like moisture, wind, snow, and other extreme weather conditions known for roof damage, creating the need for repairs. Additionally, roof sheathing acts as another layer of insulation. With properly installed roof sheathing, your home can stay warm in the winter and cool in the summer. This also improves the energy efficiency of your home.
Types of Roof Decking Material
There are different types of roof decking materials out there. Let’s take a look at different types and the variety of materials used.
Wood-Based Materials
One variety of roof sheathing material is wood-based. This type can be found in two different styles: Plywood and Oriented Strand Boards (OSB). Plywood is known for its strength and cost-effectiveness and is commonly used for residential roofing applications because it’s light and has a more natural look.
OSBs have grown in popularity over the years because they tend to be the budget-friendly alternative to plywood. OSBs are also heavier than plywood, providing higher levels of thermal conductivity.
The main con of OSBs is the material’s response to moisture. OSBs act like a sponge and because of this, excess moisture causes the material to swell. With extended periods of moisture exposure, this wood-based material degrades faster than plywood.
Metal Decking
Metal roof decking is commonly used for commercial properties. The use of steel or aluminum gives this type of decking material enhanced durability and strength.
To fit the various needs of commercial properties, metal roof sheathing is offered in a range of thicknesses, finishes, and profiles. Metal can also be installed over steel, concrete, or wood, and is typically used in flat or low-slope roofing systems.
Concrete Decking
Concrete roof decking is best used in applications where a roof requires higher levels of support. Offered in either precast boards or a concrete pour, this material’s heavy nature holds up well against extreme weather and has excellent fire resistance. Bars are installed for reinforcement if choosing concrete pours.
Signs Your Roof Decking Needs Repair or Replacement
As a homeowner, how do you know when your roof decking needs repairs or a replacement? Considering roof sheathing is one of the first layers installed in a roofing system, it can be hard to know without understanding what to look for.
Common warning signs include:
- Sagging: If you’ve noticed your roof is sagging in certain areas, there’s a possibility it’s directly linked to a deteriorating roof deck. A sagging roof is one of the common warning signs the roof deck either needs to be repaired or replaced.
- Leaks: A damaged roof deck creates an opening for water leaks. Leaks can be spotted by dripping water or water stains on the ceilings of your home. Always keep an eye out for leaks as leaving them unattended can lead to rotting.
- Mold: The presence of mold in your roofing system is a sign of moisture-related issues possibly linked to the roof deck. Since mold is a health hazard, any sign of growth must be addressed immediately.
- Rot: Any sign of rot in your roof’s decking material is a warning sign that can’t be ignored and will undoubtedly need to be addressed through repairs or a replacement. Much like the presence of mold, any amount of rot in the roof deck is a hazard.
Neglecting these issues compromises your roof’s structural integrity and increases the chances of a collapse. If you notice any of these signs or suspect a leak, mold growth, or rot, schedule a roof inspection ASAP.
Roof Decking Installation Process
Any aspect of a roofing service is part of a larger investment. It’s best to understand what services like roof decking installation entail because, at the end of the day, it’s a key role of your home’s protection.

- Collection of roof measurements to determine the size of roof decking sheets.
- Strategically position new decking sheets for strength and stability.

- Inspection for any gaps between decking sheets or instances of any overhang.
- Application of roofing felt or underlayment for preparation of last roofing materials.
Roof Decking Maintenance and Care Tips
One of the best and most effective measures in maintaining a solid roof is routine inspections. Routine roofing inspections thoroughly analyze the current condition of your roof, including the decking. If there are any issues or concerns, a routine inspection will catch them before they get out of hand. Routine roofing inspections go a long way in avoiding costly repairs or premature roof replacement.
In addition, the cleaning and treatment of wooden roof sheathing is recommended to keep the deck in a healthy and functional state. To better prevent water damage and warping, your roof’s flashing and ventilation should be inspected for damages, gaps, and leaks.
