Steep pitched roofs offer the potential for more living space

Ironically, although we are facing drought warnings today, Britain is in fact the country in Europe with the highest rainfall, a fact that has brought about the steep pitch design of Britain’s roofs.

The average rainfall per year for the UK is over a metre (109cm) and without our steep pitched roofs, rainwater wouldn’t flow off the roof so quickly and our homes would be more susceptible to leaks and floods.

The simple fact is, a pitched roof (i.e. set at an angle) is more weather tight than a flat roof as it allows the rain to slide off the roof, rather than sit on top. The typical angle of pitch in the UK is between 30 and 45 degrees and this not only has a practical purpose, but also plays a part in the asthetics of the house too. By a happy coincidence, this is also the best angle at which to place solar PV panels.

One of the big benefits of steeply pitched roofs which has emerged in recent years as more and more homeowners have taken the opportunity to increase the number of bedrooms, is the ease of converting attic space into living space.

The steeper the pitch, the more headroom in the loft, so the greater the potential living space. The roof pitch is definitely worth bearing in mind if you are self building – and of course when deciding on tiles as not all roof tiles can be used on all angles of pitch.
