A review of roof options

Let's take a look at your two main choices when it comes to roof type, flat and pitched.  Your decision will play a major part in the the overall look of your extension.

Flat Roof - Pros

  1. Flat roofs are generally less expensive to construct given the reduced areas involved.
  2. The construction period is often shorter compared to traditional pitched roofs.
  3. Access is generally easier.
  4. Internal space is not imposed on due to the lack of roof pitch angles.
  5. Flat roofs can give a great modern look for more contemporary buildings – although some more contemporary materials such as zinc can bring the costs up.

Flat Roof - Cons:

  1. Flat roofs generally require a greater degree of maintenance – even more so if the surface is disturbed and damaged by people frequently walking over it.
  2. Flat roof drainage can be not as effective as traditional pitched roofs and standing water (ponding) can be an issue if falls are not adequate.
  3. Typically, the lifespan of a flat roof is not as long as a traditional pitched roof – even less so if it is vulnerable to damage (points 1 and 2) or you live in a area subject to poor weather conditions.
  4. Successful sealing of flat roofs from water ingress can be problematic if not correctly executed.
  5. Roof repairs are generally more expensive than traditional pitched roofs.

Pitched roof - Pros

  1. The design of a pitched roof will usually blend in better with the style of more traditional houses, making it a favourite with planning departments.
  2. It also has a definite benefit of space. You can create a higher ceiling beneath it, or even use it for loft space in some instances.
  3. A longer lifespan than a flat roof can be expected thanks to more weather resistant, durable materials and a design that allows water to run off more efficiently.

Pitched roof - Cons

  1. This design cannot be used for buildings with too many multiple levels or complex plans.
  2. There are limitations on the architectural design of a pitched roof.
  3. Cost of installation is generally greater than a flat roof.

The design of your roof may be dictated by a variety of factors such as your local planning department, or what you want to use your extension for, but when you do have a choice, it’s wise to consider carefully what you can afford but also what will be the best long-term decision.
