How much is a new flat roof?

How much will a new flat roof cost?

Investing in a new flat roof can be a daunting process; it is hard to know where to begin, and how much it should cost, making it difficult to know whether you are being overcharged or not.  Here at Leak Proof we provide the best flat roofing and GRP fibreglass roofing services in Liverpool, and will always charge our customers a fair price for the service that they are receiving.  This blog will go over some of the key factors to consider when you are getting a new flat roof.


Due to the pandemic, the prices of materials that are needed for flat roofs, such as timber, felt, rubber and GRP, have increased significantly, making it more expensive for roofing companies to fit them.  This increase is due to slower rates of manufacturing, higher demand and backlog, less transport and deliveries, and a whole host of other reasons too.

What should a flat roof cost?

Before the pandemic, it used to be that a flat roof installation would cost anything between £60 and £100 per square metre.  However, as discussed above, this price has increased as the price of goods has gone up, and now a customer can expect to pay between £80 and £150 per square metre, depending on the nature of the job.

Of course, the price of the roof as a whole will vary massively depending on its size, the condition that the property is currently in, and whether roof spars and joinery need to also be factored in.  There are also optional extras such as lanterns, skylights, fascia boards, soffits and guttering, which will of course increase the price.

Things to consider about flat roofing

There are a few things that it is useful to consider if you are looking to get a new flat roof installed; these can also affect the price of the flat roof:

  • Do you require decking to be installed?
  • Does the roof need to be insulated?
  • Do you need a roof covering such as material, felt, GRP fibreglass or rubber?
  • Will the installation be warm or cold?
  • The location and height of the roof
  • Is access equipment required for the roof, such as scaffolding?
  • Is it a domestic or commercial property?
  • The current strength and condition of the flat roof
  • Is stone removal needed?
  • Is it a pitched to flat conversion?

These can all impact the cost of the roof
