Designing Your Roof

The most important consideration is clearly to make sure that the roof performs properly throughout its life.

In the UK the best result will be achieved with a pitched roof. We recommend a pitch of between 30⁰ and 45⁰. This is the best angle to cope with British weather, allowing rain and snow to run off the roof surface quickly.  

Fixing the tiles

You should consider the weather conditions that affect the location of your self build. High wind and rain levels will affect the design, particularly in relation to the fixing methods you will need to keep the tiles securely attached. Dry Fix is always a good option, but in areas of high wind it is particularly important.

Remember to consider ventilation in the roof space – inadequate ventilation can lead to condensation in the roof space, so both high level (at the ridge) and low level (at the eaves) should be included. There is a British Standard, BS 5250, that explains this.

Solar power

While you are creating a new roof it is a good idea to include some power generation. Look at our section on Solar Power Roofs to see how you can integrate solar panels: these can generate around 40% of the electricity you will need to run your home and there are generous financial incentives to help with the cost.

When it comes to the design of the roof you should consider the style of surrounding buildings. In some areas there will be planning regulations that dictate the style and colour of tiles you use, but, if not, you have free reign to design the roof you want.  

Design

And finally, look for inspiration in our Roofing Inspiration section. There is a huge amount of decorative detailing that can be included in the roof design which will add hugely to the look of the building. Whether you are looking to re-create a period feel or create a contemporary classic remember that the sheer size of the roof will have huge visual impact that will dictate the character of the house.
