What is Roof Decking? Types and When Should It Be Replaced?

1. What is the decking on a roof?

The decking on a roof is the layer of material that lies on top of the roofing felt or membrane. It provides a surface for the application of shingles or other roofing materials, and protects the roofing materials from the elements.

There are two types of decking: plywood and OSB (oriented strand board). Plywood is the traditional material, and is still used on many roofs. It is made of thin sheets of wood that are glued together. OSB is a newer material that is made of wood chips that are compressed and glued together.

Both plywood and OSB have their pros and cons. Plywood is stronger and more resistant to water, but it is also more expensive. OSB is less expensive, but it is not as strong and is more susceptible to water damage.

When choosing decking for your roof, you will need to consider the climate and the type of roofing materials you will be using. In areas with high humidity or lots of rainfall, plywood is a better choice. In colder climates, OSB is a better choice because it is less likely to crack in the cold weather.

If you are unsure of which type of decking to use, you should consult a professional roofing contractor. They will be able to help you choose the best decking for your roof and climate.

2. What is the best type of roof decking?

When it comes to roof decking, there are a few different types to choose from. But what is the best type of roof decking? Here’s a look at some of the most popular options to help you decide.

Plywood: Plywood is a popular choice for roof decking because it’s strong and durable. It’s also easy to work with, making it a good choice for do-it-yourselfers. However, plywood can be susceptible to water damage, so it’s important to make sure it’s properly sealed and protected.

OSB: OSB (oriented strand board) is another popular type of roof decking. It’s similar to plywood in terms of strength and durability, but it’s more resistant to water damage. And like plywood, it’s easy to work with, making it a good choice for do-it-yourselfers.

Metal: Metal roof decking is a more expensive option, but it’s also more durable and longer lasting. It’s also fire resistant, which can be a good choice if you live in an area with a high risk of wildfires.

Composite: Composite roof decking is a newer option that’s made from a mix of wood and plastic. It’s designed to be more durable and weather resistant than traditional wood decking.

So, what’s the best type of roof decking? It really depends on your budget and your needs. If you’re looking for something strong and durable, plywood or OSB are good choices. If you’re looking for something more fire resistant, metal decking might be a good option. And if you’re looking for something that’s more weather resistant, composite decking could be the right choice for you.

3. What are the advantages of roof decking?

Roof decking is the material that lies on top of your roofing system and provides protection from the elements. It is often made from plywood or OSB (oriented strand board) and is attached to the roof trusses or rafters. Roof decking can also be made from metal, concrete, or even cardboard.

The main advantage of roof decking is that it provides a solid foundation for your roofing materials. This is especially important in areas with high winds or where there is a risk of severe weather conditions. Roof decking also helps to protect your home from moisture and pests.

Another advantage of roof decking is that it can help to insulate your home. This is because the material helps to keep heat in during the winter and cool air in during the summer. This can lead to lower energy bills and a more comfortable home overall.

Finally, roof decking can also add to the aesthetic of your home. This is because the material can be stained or painted to match the exterior of your home. This can give your home a more polished look and can even increase its curb appeal.

4. How is roof deck made?

The roof deck is the layer of material that lies between the roofing material and the insulation. It provides a flat, level surface for the installation of the roofing material and acts as a barrier to prevent moisture and wind from damaging the insulation. The roof deck is typically made of plywood, OSB, or gypsum board.

Plywood is the most common type of roof decking. It is made of thin sheets of wood that are glued together. OSB is made of chips of wood that are glued together. Gypsum board is made of calcium sulfate that is mixed with water and pressed into sheets.

The roof deck should be replaced if it is damaged or if the roofing material is being replaced. The roof deck can also be replaced if the homeowner wants to change the type of roofing material. For example, if the current roofing material is asphalt shingles, the roof deck can be replaced with plywood so that metal roofing can be installed.
