Installing a new roof for your home, conservatory, garage or commercial building isn’t a decision you want to take lightly.

Whilst most of us wish we had endless funds to spend on whatever home improvements we’d like to make; in reality you probably have a fixed budget in mind when it comes to installing your new roof.

It pays to be aware of the different types of roof available, and their pros and cons, as well as their prices. With that in mind, we thought we’d have a chat with you about the price difference between flat roof and pitched roof set-ups.

We’ll also discuss some of the other key points to consider when shopping for a new roof for your home…

The Pros of Flat Roofs

Flat roofs get a bad rap and it’s not entirely justified. Like anything, there are pros and cons to installing a flat roof and we’re here to highlight some of those pros:

  • Flat roofs take less time to install than pitched roofs
  • Less materials are required for installation
  • A flat roof will keep your home warmer than a pitched roof as it attracts sunshine
  • Flat roofs are more accessible so new installation or repairs are easier

If professionally installed, regularly inspected and well maintained, flat roofs can be an excellent, affordable choice for your home or commercial building.

It’s true that they generally have a shorter life span than pitched roofs (the average is around 20 years). But depending on the type of flat roof you choose and how much time you spend maintaining it, this could be extended to up to 50 years in some cases.

The Cons of Flat Roofs

Now, onto the cons. Flat roofs do need to be regularly inspected and maintained in order to prevent problems occurring. Because they’re flat, they are more prone to leaking and other issues.

A flat roof generally requires more maintenance than a pitched roof, so it’s worth factoring in the cost of this to the price of installing your new roof.

It’s also worth considering the average lifespan of a flat roof too, which is only around 20 years – and that’s with regular maintenance.

It’s important to ensure your flat roof is professionally installed, as contractors who know what they are doing will select the correct materials and ensure a perfect installation; reducing the risk of leaks, or other problems further down the line.

What’s the Price Difference Between a Flat roof and a Pitched Roof?

There’s a significant price difference between flat roof and pitched roof projects, and it’s one of the main reasons so many people choose a flat roof for their conservatory or garage.

Generally speaking there are five different types of flat roofs available: single-ply, roll asphalt, multi-ply, flat-seamed metal and modified bitumen roofs.

The type of roof you select will affect the cost and therefore the price difference between flat roof and pitched roof projects may be significant or less significant depending on your choice.

The price you pay will also depend on the accessibility and location of your home or commercial building and the size of the project. As a general guide, a flat roof installation in 2018 could cost:

  • Around £40-50 per square metre for a torch-on flat roof (felt roof)
  • Around £80 per square metre for a rubber roof
  • Around £300 per square metre for a lead bay roof
  • Around £1,200 for a typical single garage

This is only a guide and bear in mind that you’ll also need to factor in the cost of insulation for your new roof. Flat roofs can be insulated with a wide range of materials including wood fibre, perlite, expanded or extruded polystyrene, cellular glass or polyisocyanurate.

The choice of insulation will affect the final cost of your flat roof! When you consider that the average cost to install a pitched roof on a three-bedroom house is between £4,000 and £7,000, it’s easy to see which option is cheaper!

Which Should You Choose? Final Verdict
