how much does it cost to build a deck with a roof on it

A deck can greatly increase your enjoyment of your home and give you some extra space. 

However, if you live in a sunny area or an area with a lot of rain, this can be an issue. You can end up only being able to sit out on your deck for half the year. 

One of the best ways to mitigate this problem is to build a deck with a roof. 

Covered decks are not only great for everyday use, but they also increase your home’s value. Features like this can make your home more desirable and fetch a higher sale price. 

In this article, we have laid out the cost of building a deck with a roof on it. By knowing what a project like this will cost, you can plan for your very own. 

Building a deck with a roof on it can be split into several different categories of price. These include: 

  • Labor cost 
  • Materials cost
  • Cost of the deck itself
  • Cost to add a roof 

Why Build a Deck With a Roof on It?

One of the main reasons to build a deck with a roof on it is to be able to use it year-round. When your deck is exposed to the elements, this decreases the amount of time you can use it. 

Most people want to be able to enjoy their deck whenever they want. However, even when it is nice out, the sun can make that extremely difficult. 

A roof on your deck will fix that and make it usable no matter what the weather is like. 

A roof can also protect the actual deck itself from sun and water damage. 

Just like you, your deck is sensitive to the weather and the various elements. A roof will keep the deck itself safe from fading, mold, and mildew.  

Cost of Labor 

Perhaps one of the biggest expenses when building a deck is the labor. 

A deck is a fairly complex project and will require professionals to be built correctly. Professionals can also make sure that your deck is in compliance with all of your local building codes. 

Generally, labor costs between $15 and $35 per square foot. 

This number will be determined by several factors including where you live and what your house is like. It is important that you get a quote before you agree to have your deck built. 

Cost of Materials

Materials are another very important consideration. There are all kinds of decking materials, and they will all have their own costs. 

Pressure-treated wood decking will cost between $15 and $20 per square foot. Plastic decking will usually cost between $30 and $40 per square foot. 

While plastic decking is more expensive, it will also last quite a bit longer than wood decking. It will also be more resistant to fading. 

Cost of Deck

The type of deck you choose to build will also greatly influence the cost. 

A floating deck will usually cost between $20 and $60 per square foot. However, this type is not always necessary and maybe the more expensive, less practical option. 

A platform deck is the most common type that most people install. These stick out from the side of the house and are relatively easy to build. 

Platform decks usually cost around $10 to $20 per square foot to build. This makes them very accessible to most people. 

Cost of Roof 

The cost of the roof itself is quite varied. Depending on what you are looking for, you could end up paying much more. 

Generally, a roof for your deck will cost between $6,000 and $26,000 to build. 

While this is a wide range of price points, you can save money by not having to do as much maintenance. You can also keep your deck looking much nicer for longer.
