How much does a flat roof cost?

If you require flat roof installation, whether this is for a new build or you are replacing an existing roof, it’s important that you budget accurately to establish how much you’ll be paying. After all, you need to ensure that it is going to fit into your budget. It is important to understand that there are a lot of different factors that are at play when it comes to determining the cost of a flat roof, and because of this, the price can range anywhere from £1,000 to upwards of £5,000.

Yes, this is a wide range in price. However, you need to factor in the experience of the roofer, the location, the materials used, and the size of the flat roof, as well as a number of other factors. If your roof is difficult to access, more equipment is going to be needed, and this can also add to the cost.

Flat roof cost factors

Flat roofs are popular in a number of different circumstances, for example, for out-houses and garages. However, they can differ in price depending on a number of different factors. So, let’s take a look at the cost of a flat roof in more detail below so you can get a better understanding.

1. Cost of materials

The materials used within the construction of the flat roof do play a critical role. You have many different options to select from, including lead, fibreglass, single ply membrane and felt. The roofing company you hire should help you to understand the options at your disposal so that you can make the best choice for your project.

Naturally, some materials are going to be more expensive than others. If you were to choose a felt flat roof, for example, then the price per metre squared is typically somewhere between £40 and £70. Other materials tend to be more expensive. For example, you can expect to pay between £80 and £100 per square metre for rubber flat roofs. You can expect to pay between £80 and £110 per square metre for fibreglass flat roofs. Finally, you can expect to pay between £90 and £110 per square metre for lead bay flat roofs.

2. The size of the roof

Aside from this, you need to carefully consider the type of project that you are going to be embarking on. In most cases, a flat roof is not used to act as the main roof. We often see flat roofing used for certain sections of a property, rather than being used as the overall roof.

Nevertheless, if you are using a flat roof for the entire roof, for example, if you are looking for a roof for a bungalow or an apartment, then the price is more likely to be higher. As you would expect, the scale and size of the project is going to make a massive difference when it comes to the quotes that you receive for your new flat roof.

3. Are there any additional costs that will be added to your quote?

When figuring out how much you are going to be charged for a new flat roof, one thing that you also need to factor in is whether or not there are going to be any extra costs added to your final bill. For example, some scaffolding may be required when replacing a flat roof or adding a new one, and so there are, of course, costs associated with this. By law in the UK, scaffolding is a must for any sort of work that is carried out at a height.

There are a number of additional flat roof costs that can occur depending on the condition of your existing structure and roof as well as any bespoke requirements you may have. Consider the following questions as they’ll most likely incur extra charges to ensure the work is completed to high standard:

  • Is your roofing structure sound?
  • Do you need a replacement timber board?
  • Is insulation required to meet building regs?
  • Do you require any special detail i.e Velux rooflights, coppings etc?

Important factors when choosing a reputable roofing contractor

When searching for flat roofing costs and quotes, there are a number of important considerations to establish whether the quality of their work is up to industry standards and that you are covered in the event of any issues with the work. Ask your flat roofing contractor the following questions:

  • Are they members of NFRC Competent Person Scheme – if your roofing contractor is part of this scheme, they’ve passed a number of checks to ensure they will not only do a good job, but legal obligations are met. For example, they have to pass a financial check, complete and pass a desktop audit, office audit and a comprehensive site audit to ensure they are adhering to all British standards, building regulations and health and safety requirements. All contractors are audited annually.
  • TrustMark Registered – Alternatively, a reputable company may be TrustMark Registered. This ensures the company doesn’t have any outstanding complaints or criminal charges. Backed by the government, TrustMark assesses a roofing contractor against technical competence, good customer service and good trading practices.
  • Insurance covered – Make sure to double check the insurance details of your chosen roofing contractor. This ensures peace of mind that all checks have been carried out.
  • Can they provide a detailed quote, outlining the schedule, materials used, safety measures and protection? A reputable flat roofing contractor should be able to provide this level of detail.
  • How long have they been established and do they have a valid office with staff you can contact any time throughout the project? It’s important that you choose a contractor that clearly appears reputable and established.
