When it comes to your roof’s protection from the elements, the decking is every bit as important as the shingles attached to it. Here are the things homeowners should know about roof decking.
1. Roof Decking Also Protects Your Roof From Leaks and Extreme Weather
The roof decking provides support for the shingles, which are a lot heavier than they seem with each shingle weighing in at over two pounds. In addition, the roof decking helps distribute the impact from falling branches and other debris that lands on the roof throughout your home’s structure. Aside from supporting shingles, roof decking with waterproof materials serves as an extra layer of protection against moisture.
2. You Don’t Have to Replace Your Roof Decking Every Time You Have a New Roof Installed
Given the importance of roof decking, should you replace it every time you get a roof replacement? Not necessarily—it depends on the condition of the roof decking. A roofing contractor will inspect your roof before making a recommendation about the need for new decking.
3. Inspecting the Roof Decking Can Be Tricky
Keep in mind that inspecting the decking can be tricky. Your roofer will do their best to diagnose the health of the decking before roof replacement begins, but it’s possible that damage will only be revealed once the shingles are removed. This is why it’s a good idea to set aside a contingency fund within your roof replacement budget to cover the cost of repairing unexpected damage.
4. There Are Different Types of Decking
The contractor might recommend installing a different type of roof decking, depending on the extent of the damage and your area’s climate. The three most commonly used types are:
Oriented strand board (OSB) – OSB is made of intertwined wood strands held together by a waterproof resin.
Plywood sheathing – Its dense composition makes it resistant to moisture.
Step sheathing – Step sheathing boards are separated by a few inches of space to allow air to circulate underneath the shingles.
