What is Flat Roofing Installation?

Whether you’re looking for a replacement roof for your garage or a new roof for your extension, a flat roof is often an appealing option.

Flat roofs are generally the cheapest type of roof, making them a popular choice. Choosing to hire a professional roofer will ensure that your flat roof is properly installed, reducing the chance of problems occurring.

Contrary to popular belief, a flat roof shouldn’t be completely flat. To prolong the life of your flat roof, it should be slightly angled to allow rainwater to escape into gutters or outlets and avoid pooling. This will give your flat roof the best possible chance of achieving a long life.

What changes the price of Flat Roofing Installation?  

The price that you’ll pay for your flat roofing installation will be influenced by several different factors including:

  • Roof size

  • Specification

  • Location

Roof size

The cost of your flat roof installation will be dependant on the size of the roof you require. For example, a flat roof for a single garage could cost £1,000 whilst a flat roof for a double garage might cost £1,500. The bigger the roof you require, the higher the price of flat roofing installation will be.

Specification

The specification that you choose for your flat roof will impact the price. You’ll have the option to specify the thickness and type of both the roofing membrane and the insulation. Certain options will come with a higher price tag, based on their cost and quality.

Location

Your location will also influence the cost of flat roofing installation. The price of hiring a roofer varies across the UK, with prices typically higher in the South of England and in London. However, the prices should still fall within the average price range.

How to reduce the cost of Flat Roofing Installation

If you’re looking to reduce the cost of flat roofing installation, there are a few things that you can do to keep the price down.

  • If you’re replacing an existing flat roof, the easiest way to keep the cost down is to recover the existing flat roof. This will speed up installation whilst reducing labour costs and minimising disruption.

  • You’ll be given options for the type and thickness of the roofing membrane that you require. Generally speaking, the thicker the membrane, the longer it will last. This membrane often comes with a warranty. You can reduce the price of your flat roofing installation by choosing to go without the warranty, or opt for a shorter warranty.

  • You will also need to consider how much insulation you need. You can improve the insulation by opting for two thinner layers of roof insulation instead of one thicker layer. This will improve the R-value performance along with reducing air leakage. This will help you to keep the costs down as you can get the same performance with less insulation.
