Do you want a flat roof extension, but are worried about how much it might cost you? There are many reasons why you might want to get a flat roof extension, but the threatening cost of one could be a large reason why many put it off for too long.
Today we’ll be looking at everything you need to know about a flat roof extension as well as how much it is likely to cost you.
What is a flat roof extension?
A flat roof extension is a single storey extension built on either side of the house, or on the back of the house. They can be ideal for people who want extra space in their homes without having to pay for a full-height extension.
Full-height extensions might look more appealing and offer more space on both storeys of your house, but they are much more expensive and take up more space than you might have to spare.
So, a flat roof extension can be a happy medium between getting more space in your house and spending too much money on a two storey extension with a pitched roof.
You might also be forced to get a flat roof extension rather than a pitched roof extension due to neighbouring properties being too close or incorrectly shaped for a pitched roof to be a good idea.
How much will a flat roof extension cost?
The exact price you’ll be looking for when it comes to your flat roof extension is impossible for us to predict. There are many factors that will come into play when getting your estimate, including your location, the materials used, and the contractor that you opt for.
However, the construction industry does have an average for flat roof extensions which is around £52,500. This is based on the average size that the majority of people opt for when choosing the size of their extension. Smaller extensions will cost less, with an average price of £30,000, while larger extensions will come with a higher price tag closer to £75,000.
These figures might not be helpful to you when you cannot visualise how large these extensions will be. Perhaps a better way to look at it is that per square meter of flat roof extension, the average cost is £1,850, with a range between £1,200 and £2,500.
When comparing these prices to a pitched roof extension, you’ll be saving money on the flat roof option. The average costs of a pitched roof extension are between £40,000 and £80,000 with an average of £60,000.
Flat roofs are not typically as aesthetically pleasing as pitched roofs and they can get damaged quicker than the latter. If you chose to convert your flat roof into a pitched roof on an extension you’d be looking at a price of between £3,000 and £4,000 to do so.
Why get a flat roof extension?
There are many reasons why you might choose to get a flat roof extension. They add extra space to a house and give you another room to make your own and let your creativity run wild. You can use the extension as another bedroom, a larger living space, or a hobby room.
Flat roofs are cheaper than pitched roofs while still allowing you to change your mind at a later date and opt for a pitched roof. Some people like the flat roof look; however, as it is modern, stylish, and you can decorate some flat roofs better than pitched roofs.
Flat roof extensions can also increase the value of your home if you were looking to sell in the future, especially if you chose to install an impressive feature such as a skylight. You can also add a roof terrace if you wanted to, creating more space for socialising and making your house look all the more impressive.
Factors that could affect the price of your flat roof extension
As we mentioned earlier, there are many factors that can affect the price of your flat roof extension. With the price ranging from £30,000 to £75,000, there must be a lot of factors that have the ability to affect the price. Let’s look at a few of the most prominent ones.
First up we have the materials used. You might have the ability to influence the decision of which materials are used, or your contractor might use their favourites. Higher quality materials will last longer, look better, and cost more. Cheaper materials have the potential to break and need replacing in a shorter period of time.
Of course, the size of your extension will also affect the cost. The larger your extension, the more materials and labour will be required to create it. This will undoubtedly cost more, whereas smaller extensions will cost less and be completed in a quicker time.
The shape of the extension will also affect the price. A simple box-shaped extension will be easier to build and therefore cost less, while a complex shape will require more labour time and therefore higher costs.
There are many more factors affecting the price, such as the architecture, condition of the space working on, added features, and how easy the job is.
Can you install a flat roof extension by yourself?
If you had the knowledge of how to build an extension, as well as the time and the connections to source all of the materials for a reasonably low price. However, you shouldn’t underestimate the task that you’re thinking of undertaking.
Building your own flat roof extension is incredibly difficult, expensive, and the risks of you doing things wrong are high. Hiring a professional will often reduce the costs as they have suppliers that offer lower prices for them.
It will also take much longer to complete your extension if you’re completing it yourself as a professional will have a team of workers, while you’ll be doing everything on your own.
