These include the decking, which plays a huge role in ensuring the roof system remains intact and your home dry and damage-free. What Exactly Is the Roof Decking? This refers to the flat surface that is attached to the roof’s basic structure. Without the decking, your system will be made up of just trusses and joists – a frame with empty spaces in between. But with this component in place, you’ll have a solid surface to where waterproof materials, such as shingles and underlayment, can attach. The Importance of a Roof Deck The roofing deck serves as an additional protective layer between your roof and home, helping reduce the risk of water infiltration. Given its essential role, the decking will need to be checked thoroughly if you’re planning to get a roof replacement. Your roofer may look for signs of dry rot or flexing in your roof deck. It may not be necessary to have the decking completely replaced along with your roof. Any damaged sections may be replaced, and those in fairly good condition will be left intact. Types of Roof Decking This component is available in several types, including tongue and groove, which is usually found in homes without a ceiling and adds an architectural element to the rafters. There’s also step sheathing, a typical option used when installing cedar shingles and the most common type, oriented strand board (OSB), which is known for its rigidity and resistance to moisture.
