What is Roof Decking? All You Need to Know About Your Roof’s Base
One of the most important parts of your roofing system is the roof decking. The decking is what holds everything else together, even though the shingles that you can see get most of the attention. As a New Jersey roofing company, Pro Builders Construction emphasizes how important it is to understand this part so that you can make smart choices about whether to fix or replace your roof.
What is Decking on the Roof?
Roof decking, which is also called sheathing, is the layer of material that sits on top of the frame of your house. It makes a flat, stable surface that can be used to put down roofing materials like shingles. More importantly, it keeps your roof structurally sound by supporting the weight of your roof and any extra loads like snow or debris.
Most decking is made of wood, like plywood or Oriented Strand Board (OSB), but plank sheathing is sometimes used too. This base layer is very important for keeping your whole roofing system strong, especially when the weather is bad.
Types of Decking for Roofs
There are a few types of roof decking materials that are often used on homes:
- Plywood: Construction-grade plywood is very popular because it is strong and lasts a long time. Plywood, which comes in different thicknesses, is a reliable building material for most homes.
- OSB (Oriented Strand Board) is the most common type of material used for roof decking these days. It is a strong and inexpensive choice that is made by pressing layers of wood strands together.
- Plank Sheathing: This older method of roof decking involves laying individual wood planks spaced apart. While less common today, it’s still used in certain types of roofs like those with wood shakes.
Why roof decking is important
Roof decking is an important part of keeping your home safe and saving energy in many ways:
- Strength and Stability: It gives your roof a strong base and helps spread the weight evenly so it doesn’t sag or collapse.
- Protection from the weather: Roof decking protects the house from wind and too much water by acting as a barrier. This lowers the risk of leaks and damage.
- Insulation: Decking that is installed correctly can help save energy by adding an extra layer of insulation to help keep temperatures stable inside.
- Support for Roofing Materials: If you don’t have a solid deck, shingles and other materials won’t stick properly, leading to premature roof failure.
When Should Roof Decking Be Replaced?
Roof decking usually needs to be replaced when a new roof is put on or when it gets damaged. Because it’s under the shingles, its condition isn’t always clear until the old roof is taken off. You will need to replace your decking if it is soft, wet, or rotting because it won’t be able to hold new materials.
Signs that you might need to replace your roof decking:
- Parts of the roof that are sagging
- Leaks or water getting in
- Dark spots or stains on the decking
- Soft or spongy areas when walking on the roof
In some places, especially for older homes, local building codes may require decking updates. For instance, old building codes let the decking be thinner or spaced farther apart. If the decking on your home doesn’t meet modern standards, it might need to be replaced when you get a new roof.
How does roof decking get rotten?
Roof decking is especially likely to get wet. Poor ventilation, leaks, clogged gutters, and even ice dams can let water get into the wood and cause it to rot. Moisture can break down the decking over time, making it weak and putting the whole roof structure at risk. To make your deck last longer, it’s important to have it inspected and fixed up on a regular basis.
How to Keep Your Roof Decking Safe
To make sure your roof decking lasts as long as possible, you should do regular maintenance on it.
Here are a few ways to protect it:
- Make sure the roof has enough air flow to keep moisture from building up.
- Keep your gutters clean to avoid water pooling near your roof.
- Check your roof after big storms or other weather events to catch damage quickly.
