1. What Is Roof Decking?
If being asked about the definition of roof decking, here is the simple explanation that we can give to you. It is an element which location is in between the components of the structure (the joists and trusses), the weatherproof layers (the materials of the roof, underlayment, and coatings), and the insulation.
To make the definition clearer, you can take a look at the picture above. There, you can see the location of the roof deck. From the same image, you can also find out that the other name of it is sheathing. That is why you should not get confused between the two terms because both of them are the same.
Because there will be different layers or materials placed onto the deck, strength is a must. If the decking of your roof is not strong enough, damages and some other problems may occur over time. That is why we can say that the quality and strength of the roof deck have a significant impact on the durability point.
2. What is Tongue and Groove Roof Deck?
Roof decking comes in at least five different types. Those include the plank, step, plywood, oriented strand board (OSB), and tongue and groove boards. The last one is none other but our main topic in this article.
There are two most common features of the wooden T&G roof deck type that you can use to identify it. The first is the “tongue”, which location is on one edge of the material board, and the second is the “groove”, which is on the other side.
In the installation, the installer will insert the “tongue” of a board to the “groove” of another board. They will repeat this action until they complete the entire decking design.
Still about the installation, before it starts, you need to make sure that the T&G boards get a special finish that will make it more resistant to several weather-related conditions. It will enhance the strength and durability of the material even better.
As we already mentioned earlier, the material of this roof deck type comes in the form of a board or plank. The material used is commonly solid wood. It can hold the weight of any other roofing materials placed on the decking. Besides, it also creates a beautiful natural look, particularly for houses with no ceiling.
3. The Use of Tongue and Groove Roof Deck
As told previously, the most common use of wooden tongue and groove roof deck type is in residential buildings. It looks even better to use for houses that do not come with any ceiling. The good thing is it is suitable to use not only in the exterior but also the interior part of your house.
The distinctive wood look of this roof deck type creates a unique appearance that you can see from beneath the roof. It even works better in specific styles, including farmhouse and rustic.
We already told you that other than this type, there is also plywood that people use quite often as the deck material in residential building roofing. The tongue and groove choice is more expensive in this case because of the solid wood material used. Although so, it offers better strength than plywood so that the higher cost is something worth it for you to pay.
One thing that you should not forget is that the price is also relative. It usually depends on the species of wood chosen. A different selection often results in a different appearance, too, no matter whether you want to add a finish to it or not.
One of the examples that many people are fond of is cedarwood. This one is not only popular because of the attractiveness of the wood grain. It is also because of the excellent weather-resistant properties that it naturally has.
4. The Benefits of Solid Wood Tongue and Groove Roof Deck
From all the sub-topics that we already discussed earlier, there are at least three benefits that you can get when choosing the tongue and groove boards material for the rood decking. To make everything even clearer for you, here is the explanation of each advantage.
Strength and Durability
Other than the tongue and groove boards from solid wood, there are some other material choices that you can use for building the structure of a roof decking. In this case, plywood is another selection used quite often in residential buildings.
FYI, plywood is sometimes available also in the form of T&G. However, this material is commonly quite thin.
On the other hand, the solid wood tongue and groove boards are more beneficial because they naturally have a better level of strength. Something like this is indeed advantageous for the entire roofing design because it makes the deck able to hold any other materials placed on top of it, including the underlay and the other roof materials.
From this explanation, it is clear that the first benefit of the T&G board roof deck is none other but the strength. It gets even better because this advantageous point also leads to another advantage, which is durability.
With durable material, the roof decking can last longer. It can also be away from damages that can lead to other roofing problems. This way, you should not think about decking replacement at any time soon.
Another significant benefit that you can find only in the tongue and groove roof deck boards is the natural appearance that comes from the wood material. It is something that you cannot find in any other choices, including plywood. Although the different options may have a faux wood look, it will not be as natural as the original solid wood appearance.
Installation Process Time Saver
The T&G design of the boards is another benefit that you must know. It is a detail that can save time in the installation process.
Do you know what it means? It means, if you want to build the deck on your own because you have the building skill, you can get the project done faster because of the tongue and groove boars styling.
If you decide to hire builders to do the project, it is still beneficial. The reason is that the T&G design makes the installation process done quickly so you can be sure that the service cost will not be over budget too.
5. Design Ideas
Now that you already know about all the facts related to roof decking from the tongue and groove category, especially the one from wood, it is the time to get inspired. Below, you will find at least ten ideas on how people from many places in the world include the material in their home design.
Pine Tongue and Groove Deck in a Rustic Porch Design
The first picture that you see here is a partial covering for a deck. The area is rather large, and the homeowners want to partially cover it so they can get extra space for spending time outside without having to deal with some weather factors, such as sunlight and heat.
As you can see, the covering has an exposed roof decking. FYI, the material used here is the same as the timber choice, which is pine. This selection is simply fantastic because it creates a complementary look to the existing timber material of the deck.
This idea seems to proof that coloring is not always necessary in roof decking design like this. However, it would be beneficial to add a protective finish to it to lengthen the strength and durability.
Douglas Fir Tongue and Groove Deck in an Eclectic Living Room
As we already told you earlier, the T&G roof decking is a thing that you can include not only in home exterior design but also in the interior. The image that you see here is the proof.
It is a photo of an eclectic living room that feels so open so that plenty of natural light can get in there easily. As you can see, the design of this place does not include any ceiling. Instead, there is a roof decking.
The material chosen by the designer here is Douglas fir. It is a species which origin is from eastern Asia and North America. It belongs to the category of timber trees and has a strong characteristic. That is why people use it a lot in constructions, including for creating the T&G material for roof decking.
Pre-finished Pine Tongue and Groove Roof Deck in a Rustic Entry Interior with Loft
Here is another fantastic example that we want you to take a look at. It is the picture of the interior of a rustic entry, which also seems to have a loft at the upper part.
Here, the type of wood chosen for the T&G roof decking is pre-finished pine. A material like this is an excellent choice because you can directly use it without sanding and finishing first. All those procedures have been done in the factory, and that is why the name is pre-finished wood.
Another stunning inspiration that you can see from this idea is that the use of the material is not only on the roof decking. You can see clearly in the picture that it also appears on the wall even is the style is not T&G, but half log.

The final look does not only affect the appearance of the wooden T&G material. It also affects the whole space and makes it gains an airy and light feel so that it becomes a more comfortable place that the homeowners can use to spend time.
Besides, you can also see the choice of the black and grey furniture set lying in there. The whitewashed roof deck seems to create a balance so that the sunroom does not feel too dark and gloomy.
Cedar T&G Roof Decking in a Pool House
The picture that you see here is the interior of a residential pool house. As you can see, the place has the domination of wood materials, including the T&G roof deck, which is from a red cedar.

Overall, all the wooden material used in the design creates a warm atmosphere. It also looks cozy with a woody appearance that is not dark at all. Plus, there are also some additions of white tone that brightens up the room, including from the beadboard material, the windows, and the doors.
White T&G Roof Decking in a Solid Patio Cover
If you want to create a solid patio cover, you can also include the T&G roof decking as a part of it. A detail like this can enhance the structure style value as well as adding a natural touch to it.
As an example, you can take a look at the picture above. The solid patio cover here is rather large and tall.
It has T&G decking as the detail of the room. The design is quite interesting because there are open parts right in the center of the solid cover that allows some natural light to brighten up the patio area under it.
Wooden T&G Roof Decking in a Gazebo Design
Another idea that you can see in this picture is the use of T&G roof decking in a gazebo design. At a glance, you can see that the type of wood used for this element is not the same as the worn-out timber material of the structure. However, you can see how both of them complement each other nicely.
The T&G roof deck color even looks nice being paired with the bricks of the fireplace and pavers of the flooring under it. Together, they create not only a cozy place to hang out outside the house but also a space with a natural touch to enjoy.
