Sheathing, another name for roof decking, is an essential structural element of your roofing system. It helps disperse weight, offers a sturdy foundation for roofing materials, and is essential for shielding your house from weather-related damage. Decking may need to be replaced whole or in part over time if it rots, warps, or becomes compromised from age or water damage.
Replacing roof decking can be done if you’re familiar with safety and home remodeling projects. However, a lot of people decide to hire a professional like PJ Fitzpatrick to do the work because of the complexity and potential dangers involved. Here is a thorough tutorial to assist you with how to replace roof decking.
