Types of Roofs in UK

Gable Roof

A gable roof, also known as a pitched or peaked roof, is one of the most popular types in the UK. This design features two sloping sides that come together at a ridge, creating end walls with a triangular extension, known as a gable, at the top. The simple design makes it easy to build and suitable for many types of architecture. Gable roofs can be covered with a variety of materials, including clay, concrete or slate tiles. However, it's essential to ensure that the roof is adequately braced against wind, and it's not ideal for high-wind areas.

Hip Roof

A hip roof, or hipped roof, is a common roof style that features all sides sloping downwards to the walls, typically with a gentle slope. Unlike a gable roof, there are no vertical sides or gables. Hip roofs are more stable than gable roofs due to the inward slope of all four sides, making them a better choice for high-wind or hurricane-prone areas. The construction of hip roofs is more complicated and requires more building materials than the gable roof. They can be covered with the same types of roofing material as gable roofs, concrete, clay as well as slate and metal tiles.

Hip to Gable Roof

A hip-to-gable roof is a modification of the hipped roof style. It involves changing the sloping (hipped) side of the roof into a flat (gable) side. This conversion extends the interior space, making it a popular choice for loft conversions. The modification results in a significant increase in space, providing additional room for a home office, an extra bedroom, or even a new bathroom. As with gable and hip roofs, the hip-to-gable roof can be covered with a wide range of materials, including concrete, clay, slate tiles, or metal sheets. Despite its advantages, it's important to note that planning permission might be required depending on the local regulations and the extent of the changes to the roof structure.

Dutch Roof

The Dutch roof, also known as a Dutch gable roof, is a blend of the features of a gable and hip roof. This design starts with the hip roof structure, but instead of having the sides slope down to the walls, it has a small gable at the top. The combination of gable and hip designs in a Dutch roof brings the benefits of both styles, giving it the stability of a hip roof and the added space of a gable roof. The design of the Dutch roof is more complex than the other three types, requiring more materials and expertise to construct. Like the other types, Dutch roofs can be covered with a variety of materials, such as concrete, clay, slate tiles, or metal sheeting. It's worth noting that, due to the extra detail in the roof structure, the cost for a Dutch roof can be higher than for a basic gable or hip roof.

Mansard Roof

A Mansard roof, also known as a French roof, is a four-sided roof style characterised by a double slope on each side that meets to form a low-pitched roof. The lower slope is steeper and more vertical than the upper. This design offers extra living space under the roof, often referred to as the "attic" or "loft", and is commonly used in France, hence its name. It's also a perfect choice for those considering future home expansions. The construction of a Mansard roof is more complex and requires more materials compared to the gable or hip roof, reflecting a higher cost. As for materials, Mansard roofs can be designed with a variety of options including, but not limited to, concrete or clay tiles, metal, slate, and shingles. While offering added flexibility in terms of space utilisation, it's important to note that Mansard roofs are not ideal for areas with heavy snowfall due to their low-pitched portion.

Flat Roof

A flat roof, as the name suggests, is a roof which is almost level in contrast to the many types of sloped roofs. The slope of a roof is also known as its pitch. Flat roofs are an ancient form, mostly used in arid climates and allow the roof space to be used as a living space or a living roof. Modern flat roof designs are typically covered with a waterproof membrane and usually include a drainage system to prevent water from pooling and causing damage. Despite the name, no roof should be entirely flat – a slight slope ensures water can run off and drain correctly. Flat roofs can be covered with a variety of waterproofing materials, including bitumen, PVC, TPO, and EPDM. They are popular for commercial buildings due to their cost-effectiveness and efficiency in terms of space utilization. However, they require regular maintenance to prevent leaks, especially in regions with heavy rainfall or snowfall.

Shed Roof

A shed roof, also known as a skillion or lean-to roof, is a single, sloping roof surface, often not attached to another roof surface. This roof style is akin to a flat roof but has more pitch. It is typically used for additions, porches, sheds, and other structures. It is also increasingly popular in modernist and Scandinavian style homes due to its unique and simple design. A shed roof is relatively easy to construct and uses fewer materials than other roof types. However, care must be taken to ensure a sufficient slope to allow for proper water runoff. As with the other roof types, a shed roof can be covered with a range of materials, including asphalt shingles, metal, and EPDM. Despite its benefits in terms of cost and simplicity, a shed roof may not be suitable for regions with high winds or heavy snowfall due to its single sloped structure.

Garage Roof

Garage roofs come in various types, often mirroring the design of the main house’s roof to maintain a consistent aesthetic. The choice of the garage roof might depend on factors such as local climate, the architecture of the house, and personal preference. Among the commonly used garage roof types are flat roofs and gable roofs.

A flat garage roof, while appearing completely level, typically has a slight slope for water drainage. It is relatively easy to construct and can be covered with waterproof materials such as EPDM, PVC, or bitumen. While being more cost-effective, flat garage roofs often require more maintenance, particularly in areas with heavy rain or snowfall.

On the other hand, a gable garage roof features two sloping sides that come together at a ridge, creating a triangular shape. This design allows for better water runoff and is more suitable for areas with heavy precipitation. The construction of a gable garage roof is a bit more complex and might cost more than a flat roof, but it demands less maintenance.

In terms of materials, garage roofs can utilise the same materials as residential roofs, including concrete tiles, clay tiles, and slate. The selection of materials would depend on factors such as durability, cost, and the desired aesthetic look.

Butterfly Roof

The butterfly roof, characterised by its distinctive 'V' shape, is a modern and aesthetically appealing roof style. The design consists of two tandem pieces which are angled upwards from the middle, giving the appearance of wings in flight – hence the name 'butterfly'. This type of roof is particularly efficient in collecting rainwater, as the design naturally allows water to gather at the central point, from where it can be directed to a specific location. This makes it an excellent choice for regions with a high amount of rainfall or for homeowners interested in rainwater harvesting. The butterfly roof also offers ample opportunities for large, tall windows, resulting in a well-lit, naturally ventilated interior. However, the construction of a butterfly roof is complex and may require more materials than more traditional roof types, typically resulting in higher costs. This roof type can be covered with a variety of materials including, but not limited to, asphalt shingles, metal, or EPDM. Despite these advantages, butterfly roofs are not typically recommended for areas with heavy snowfall, as the design does not promote efficient snow runoff.

Gambrel Roof

A gambrel roof, often referred to as a barn roof, is a design characterised by the presence of two slopes on each side of the roof. The lower slope is significantly steeper than the upper one, which is almost flat. This design is reminiscent of a bell shape and is commonly seen in barn houses, hence the name. The gambrel roof design allows for a significant amount of space under the roof, making it perfect for additional living or storage areas. From a construction standpoint, gambrel roofs are relatively easy and economical to build, as they require fewer materials compared to more complex roof designs. The most frequently used materials for gambrel roofs include slate, asphalt, or wooden shingles, though metal can also be used for greater durability. However, similar to the Mansard roof, the gambrel isn't optimal for heavy snowfall areas due to the lower slope's inability to efficiently shed snow. Therefore, if chosen in such regions, gambrel roofs may require additional reinforcement or regular snow removal to prevent damage.

Dormer Roof

A dormer is a roofed structure, often containing a window, that projects vertically beyond the plane of a pitched roof. It is used to create additional space and headroom within the existing roof of a building while also allowing for more natural light to enter the space. Dormer roofs are typically installed to add an extra room within the existing structure, such as a loft conversion or attic renovation. The design of a dormer roof can vary, but common styles include the gable fronted dormer (the most common type), hipped roof dormer, flat roof dormer, and shed dormer. The choice of dormer style would depend on the existing roof structure, the desired additional space, and aesthetic preferences.

Materials used for dormer roofs often match those of the existing roof to maintain continuity. concrete, clay, slate, and metal are commonly used, but the selection would largely depend on the overall design of the building, local climate, and budget constraints. It's worth noting that while dormer roofs provide additional space and light, they also carry some challenges. These include the potential for leaks around the dormer if not properly installed and additional load on the structure. Proper design and installation are therefore essential to ensure the longevity and functionality of a dormer roof.

M Shaped Roof

The M-shaped roof, also known as the double gable roof, is a unique and easily recognizable design. It essentially consists of two gable roofs combined, forming an 'M' shape when viewed from the front. This design allows for a considerable amount of interior space, making it ideal for larger buildings or those requiring extra room for storage or living areas.

The M-shaped roof provides efficient water and snow runoff due to its sloping sides, making it well-suited for regions with heavy rainfall or snowfall. However, one potential downside of this design is the valley created where the two slopes meet, which can accumulate water or snow if not properly designed and maintained. Therefore, it's crucial to ensure adequate sealing and regular inspection to prevent potential leaks.

In terms of materials, the options for M-shaped roofs are quite diverse. They can be constructed using common roofing materials like concrete tiles, slate, clay tiles, or metal, depending on factors such as cost, durability, and aesthetic preferences. Each material has its own advantages and drawbacks, such as cost, maintenance requirements, and lifespan, so the choice would largely depend on the specific requirements of the project and the local climate.

Extension Roof

An extension roof is a type of roof designed for additions to an existing building. These could be anything from a new room to a garage or even an entire wing. The main challenge with extension roofs is ensuring a seamless integration with the existing structure, both in terms of functionality and aesthetics. There are different types of extension roofs, and the choice depends on the design of the current roof, local weather conditions, and the intended use of the extension.

One common style is the flat extension roof, which is cost-effective and easy to construct. However, they require a robust waterproofing system to prevent water ingress, especially in areas of high precipitation. There's also the pitched extension roof, which could be a continuation of the existing sloping roof or a contrasting style to add architectural interest. Pitched roofs provide excellent rainwater and snow runoff, minimising the potential for leaks.

Materials for extension roofs should ideally match those of the existing roof to maintain consistency. However, there could be instances where contrasting materials, such as metal on a previously tiled roof, might be used for added effect or due to practical reasons like the load-bearing capacity of the existing structure.

Regardless of the type and design, proper planning, design, and execution are paramount when constructing extension roofs, to ensure they not only serve their purpose but also enhance the overall appearance and value of the property.

Conservatory Roof

A conservatory roof is a unique roofing structure designed specifically for a conservatory – a glass-walled room often used for gardening or as a sunroom. Due to the nature of their use, conservatory roofs are usually constructed from transparent or translucent materials to allow maximum light entry.

There are several types of conservatory roof styles, including Victorian, Edwardian, gable-end, and lean-to, each offering a different aesthetic. Victorian and Edwardian roofs have a traditional, ornate look, while gable-end and lean-to styles offer a more modern, streamlined appearance.

The most commonly used materials for conservatory roofs include glass and polycarbonate. Glass is often favored for its clarity and long lifespan, but it can be heavier and more expensive. On the other hand, polycarbonate is lightweight and more cost-effective but may not offer the same level of clarity as glass.

In recent years, there's been a growing trend towards solid conservatory roofs, which use tiles or slates. These provide better insulation and more shade, making the conservatory more comfortable year-round. However, they may require additional structural support due to their weight.

No matter the material or style chosen, the key considerations for a good conservatory roof include adequate light transmission, insulation, durability, and aesthetic appeal. Proper installation and maintenance are also critical to prevent potential issues such as leaks, draughts, and overheating.
