Flat Roof or Pitched Roof Extension – Which One Should You Choose?

An increasing number of people are choosing to renovate rather than relocate and an extension can solve the problem of space.

Whether you’re extending your kitchen, converting a garage or even refurbishing an existing extension, the roof is a critical factor to consider.

The two main choices are either a pitched roof or a flat roof. The former is usually preferred by planning officials but the latter is better if height is restricted, so it’s not a straightforward decision.

Here’s a look at the factors you will want to consider.

Flat Roof or Pitched Roof Extension – Cost

Renovating or refurbishing your home is a big expense and it’s easy for costs to creep up.

The cost of the roof design shouldn’t be the only factor you take into account but for many households, it’s a major factor.

A flat roof extension is the cheaper option because it’s less labour-intensive to build and uses fewer materials.

The maintenance costs are lower too because the compact dimensions mean a flat roof is less likely to get damaged.

Flat Roof or Pitched Roof Extension – Planning Permission

It’s frequently easier to get planning permission for a pitched roof, especially in neighbourhoods where the properties are more traditional.

A pitched roof preserves the character of existing properties and is generally considered to fit in better with the overall look.

However, not all extensions require planning permission, especially a flat roof.

Providing the roof extension doesn’t exceed four meters in height and doesn’t rise beyond the existing roof, you won’t be required to seek planning permission (subject to the other rules being
met).

A flat roof is much more likely to meet these conditions, therefore it’s very probable that you won’t need to worry about what a planning official might think.

Flat Roof or Pitched Roof Extension – Installation

There’s no escaping the fact that building work can be disruptive. Noisy and messy, it’s a long-term gain for short-term pain!

A flat roof extension will slash the time required for the work as they’re quicker and easier to install.

The latest technology can save up to 50% on the time of building a pitched roof, while still offering a sleek and modern finish.

Flat Roof or Pitched Roof Extension – Versatile Design

A flat roof provides many more design options than a pitched roof, with different colours and finishes available.

They can also accommodate a soffit system that provides shelter for the doors and gives the appearance of the indoors flowing outside, with level external flooring.

If you have a heritage or period property, it’s also possible to fit a 25° lantern roof to create a focal point and a more vintage appearance.

Flat Roof or Pitched Roof Extension – Maintenance

We’ve mentioned above that flat roofs have lower maintenance costs because of their simple design.

This may come as a surprise as flat roofs have a reputation for causing problems with issues such as cracking, water pooling, condensation, and thermal movement reported.

The good news is that a well-fitted modern flat roof doesn’t have any of these problems, thanks to tiny tweaks in the design.

A fall system drains water effectively while a 4° pitch is barely noticeable but prevents any pooling, condensation, or other water-related problems.

The latest technology means that a flat roof can easily last 25-30 years, providing a durable solution that you can install and forget about.

Both flat and pitched roofs provide a fabulous finish to every extension; to find out more, get in touch with us today.
