Flat roofs have become a common feature on homes across the UK. While pitched roofs are the most popular choice for the main roof, extensions, garages and even bay windows can be covered with a flat roof. The question is – can you convert these flat roofs into their pitched counterparts?

In this post, we’ll look at the planning permission involved, the benefits and whether it’s the best choice for your home.

Planning permission

The short answer is yes, you can convert a flat roof to a pitched roof. But it depends on planning permission. To remain a permitted development, new roofs on a home need to:

  • Stay within 150 millimetres of the existing roof plane
  • Have no alteration above the highest point of the existing roof

Needless to say, a pitched roof will break both of conditions, as it will rise well above the existing plane and high point of a flat roof. So, you will need to apply for planning permission before doing any work on your flat-to-pitched conversion. Even with permitted developments you should check first.

Benefits of a pitched roof

Traditionally speaking, a pitched roof has a range of benefits compared to its flat counterpart. Flat roofs have a slope of less than 10 degrees, while pitched roofs are typically around 25-40 degrees. That makes it much easier for rainfall to run off.

In many cases, pitched roofs are also made from stronger materials than flat roofs, meaning they require less maintenance. On top of that, they can provide more room at the top of a property, and have a more sought-after appearance which could add value to your home.

Benefits of a flat roof

All that said, the advancements in flat roofs have made them much better competition for pitched roofs in recent years. Higher end flat roof materials are now more durable, long-lasting and low maintenance.

For less price than a pitched roof, you can now get a superior flat roof such as GRP. This can easily outlast materials like concrete tiles, making the distinction between pitched and flat less about function and more about appearance.

What’s right for you?

With flat roofs offering better longevity for a cheaper price, a pitched roof is certainly an expensive alternative. Throw into that the need for planning permission, and you may be better off simply upgrading your flat roof.

However, there is no doubt about the visual appeal of a pitched roof. All in all, it’s a question of how much you’re willing to pay for the appearance of a pitched roof. If you’re working to a budget, it’s always best to prioritise the strength and durability of the roof.
