What is a Pitched Roof?

A roof is one of the most important components of every property. 

Quite literally providing a roof over our heads, they offer important protection to every house and business, offer shade from the elements and even contain necessary insulation that can help enhance the energy efficiency of a building. 

While you might not have given it much thought before, there is actually a wide range of different roof types, all featuring different benefits and qualities. 

One of the most popular roof types is pitched roofs. In fact, here in the UK more than 90% of domestic properties have pitched roofs which make them by far the most common type in the country.  

But what is a pitched roof?

In this article, we’ll explain what a pitched roof is and the benefits it can bring.

What Is A Pitched Roof?

A pitched roof is a type of roof that slopes down from a central point. It comes down at an angle that gives it a triangular appearance and the pitch is usually the ratio of the roof’s vertical rise to its horizontal span. There are different pitches at different angles depending on what is most suitable for your individual property. 

Due to the amount of rain we experience here in the UK, pitched roofs are favoured as the angle stops the moisture from pooling and damaging the roof material. Instead, the water is drained off the roof which prevents leaks from occurring in the loft or attic space.

Many properties that have pitched roofs can also benefit from larger attics on the inside as the angle creates higher ceilings.  

Types of Pitched Roofs 

There are a wide range of different types of pitched roofs. This includes the following:

Single-pitched Roof

Also known as a mono-pitched or skillion roof, a single-pitched roof only uses a single sloped surface. This makes it one of the simplest pitched roof designs, and also more cost-effective due to the fact it is one of the easiest to construct. 

While they were initially used for extensions, these days they can be found in most residential properties across the country. Typically, a single-pitched roof is constructed using a variety of rafters that are attached to plates at the very top of the supporting walls. This allows for weight to be more evenly distributed and making the roof safer. 

As well as their cost-effectiveness and straightforward installation process, they are also extremely good at draining rainwater and snow as well as improving the aesthetics of your home.

Double-pitched Roof 

A double-pitched roof is what most people think of when considering pitched roofs. Also known as a gable roof, they use a traditional style and are regarded as one of the most common choices in the UK.

It uses a triangular design which incorporates two sloping sides that meet together to form a ridge. As well as rafters, it also has a horizontal beam known as a purlin that offers support and takes the loads of the rafters. 

They’re also extremely attractive in terms of style, and they are also easy to build. 

Hip Roof

A hip roof is a pitched roof type that consists of four sloping surfaces (one on each side) with each side meeting at the top of the ridge of the roof. 

Usually, the slopes will be symmetrical on all sides which allows for greater airflow and provides great protection against severe weather like heavy winds, rain and snowfall.

Mansard Roof

Sometimes described as a French roof, a mansard roof is a four-sided pitched roof that features double slopes on each side. These roofs are considered to be very traditional in terms of design, and were named after the 17th Century French architect Francois Mansart who invented the design. 

If you visit Paris or other French cities, you will likely see Mansard roofs in a wide range of places, especially hotels. 

The design has now spread around the world, including here in the UK. Their popularity has largely grown due to the classic, elegant look they offer. As well as the aesthetics, Mansard roofs are also extremely functional and offer significant head room on the top floor or attic. 

Butterfly Roof

If you want something a bit different or more contemporary, then a butterfly pitched roof may be the best choice for you.

With two slopes joining at an angle to form a V shape, this roof is so named due to the butterfly-winged design it offers. The biggest benefit of a butterfly roof is that it allows for bigger windows to be installed.

Benefits of a Pitched Roof

A popular architectural feature in the UK, there are a whole host of advantages of pitched roofs including:

Improved Water Drainage

One of the most significant advantages of a pitched roof is its ability to efficiently shed water, snow and debris. The sloped design allows rain to flow naturally into gutters and away from the building. This reduces the likelihood of water pooling which can cause leaks or structural damage. This efficient drainage system also prevents the build-up of snow or ice during the colder months of the year.

Enhanced Durability and Longevity

Pitched roofs tend to be more durable compared to flat roofs. Due to their slope, they can better withstand various environmental pressures like heavy rainfall, wind and snow. These elements will be less likely to accumulate on a pitched roof, which helps prevent moisture from entering your property, mould growth and weakening structures, enhancing longevity.   

Better Thermal Performance

Pitched roofs provide far better thermal performance than flat roofs. The extra space created by the sloping design can be used for installing insulation materials, which helps in regulating indoor temperatures. During the winter months, it will help to retain heat and during the summer it assists in keeping houses cool. Additionally, the attic space created beneath the roof acts as a natural barrier between the exterior and interior of the house – improving energy efficiency further.
