Factors that Affect the Flat Roof Replacement Cost
The total cost of roof replacement depends on different factors like roof size, material, and labour charges. Below, we mentioned these factors to give you a better idea of what to expect.
1- Roof Size
The cost can change according to the size of the roof. A larger roof needs more materials and takes more time to fix or replace. On the other hand, small roofs require less time and labour. The slight differences in size can change the total price, so make sure to measure carefully when getting quotes.
For example, replacing a 10m² roof is much cheaper than a 30m² roof because the cost of the roof increases with the size.
2- Type of Flat Roof Material
The material you choose for your flat roof has a big impact on the total cost and how long the roof will last. Here are the most common materials used in Enfield:
Felt Roofing: It’s easy to install and good for small areas, but it doesn’t last as long. It can last 10–15 years and costs around £40–£70 per square metre.
EPDM Rubber Roofing: It is great for larger roofs and can cost you around £80–£100 per m² and last over 20 years.
GRP Fibreglass Roofing: This material is strong and waterproof. It’s a bit more expensive but very long-lasting. It costs around £90–£120 per m².
PVC or TPO Roofing: It is used more in big or commercial buildings. It’s a premium option and costs around £100–£130 per m².

3- Labour Costs
Professional roofers in Enfield usually charge between £180 and £250 per day. Labour makes up a big part of the total cost. If your roof is easy to access, it will take less time and cost less. But if the job is complex, like working around skylights or chimneys, it may take longer and cost more.
4- Scaffolding
If your flat roof is high or difficult to reach, the roofer may need scaffolding. This keeps the workers safe and makes the job easier. Scaffolding usually costs between £300 and £600, depending on how long it’s needed. For single-storey garages or extensions, scaffolding might not be necessary, but for taller buildings, it is always required.
5- Removal of Old Roof
Removing the old roof and disposing of the materials also adds to the cost. If there’s just one layer, it’s usually easy to remove. But if there are multiple layers, it takes more time and effort. You have to pay around £500 – £1,200, depending on the size of your home and the type of roofing material being removed.
6- Permits
You usually don’t need planning permission to replace a flat roof in Enfield unless you live in a listed building or conservation area. However, building regulations still apply, and it’s best to check with the official Enfield Council website for any specific rules. Some councils charge £100 to £300 for inspection and approval.
7- Additional Repairs
Sometimes, the roofer finds other things that need fixing. These extra jobs will add to the final bill:
- Gutter Cleaning: Old or blocked gutters should be cleaned or replaced. This costs around £50 to £150.
- Fascia and Soffit: These are the boards that sit just below the roof. Replacing them costs £300 to £600, depending on the size of your home.
- Roof Insulation: If your roof isn’t well-insulated, it’s a good idea to fix it. Insulation reduces heat loss and saves money on bills. This can cost around £300 to £1,000.
DIY vs Professional Roof Replacement Cost
You might think of doing the roof replacement yourself to save money, especially if you’re good at DIY. But before you decide, here’s what you need to consider:
DIY Flat Roof Replacement Cost
If you choose to do it yourself, the biggest benefit is saving on labour. You’ll only pay for materials, tools, and possibly waste removal. A small roof replacement might cost you £500 to £2,000.
However, roofing is not a simple job. It involves working at heights and doing proper sealing. If you make a mistake, like causing a leak, it can be costly to fix. Also, DIY jobs don’t come with any warranty, so you’ll have to pay again if something goes wrong later.
Professional Flat Roof Replacement Cost
On the other hand, hiring a professional roofing company typically costs more, ranging from £1,500 to £5,000, depending on the size and condition of the roof. But in return, you get expert work from someone who knows how to handle different materials and roof types.
Most importantly, their work often comes with a guarantee of 10 to 20 years, giving you peace of mind that your roof is protected.
Cost-Saving Tips for Flat Roof Replacement
Here are some easy ways to reduce the overall cost of your flat roof replacement without compromising on the quality:
- Always get 3 to 5 quotes from local Enfield roofers. Prices can vary a lot between companies, and getting different quotes helps you avoid overpaying.
- Pick a material that fits your budget and long-term plan. EPDM might cost more upfront than felt, but it will last much longer and save you money in the long run.
- Roofers are usually busiest in summer. If you schedule your roof replacement in early spring or late autumn, you might get a better price or quicker service.
- If your gutters, fascia, or insulation also need fixing, do them all at once. This is usually cheaper than doing them one by one later.
Conclusion
Replacing a flat roof in Enfield is a major expense, but understanding the costs and options makes the process much easier. Whether you’re dealing with a small repair or a full roof replacement, knowing what affects the price, like materials, labour, and roof size, can help you plan better.
While DIY may seem like a cheaper option, it comes with risks that could cost more in the long run. Hiring a professional offers peace of mind and long-lasting results. With the right planning, you can protect your home and your budget at the same time.
