Most Common Roof Shapes
The most common roof shapes include gable, hip, mansard, gambrel, flat, and low slope.
Gable
A gable roof is an incredibly popular choice among U.S. homeowners due to its distinctive shape, with two sloping sides that meet at a ridge. This junction creates triangular end walls, known as gables.
Various materials, including siding and stone, can be used to construct these end walls. Many roofing materials, like asphalt shingles, cedar shakes, or slate tiles, are suitable for gable roofs, giving them versatility in style and appearance.
Known for providing ample attic space and excellent ventilation, a gable roof is a practical yet aesthetically pleasing choice for any home structure.
Hip
A hip roof stands out as one of the most common roof shapes. This design offers all four sides sloping downwards from the peak, creating an elegant and functional structure. A hip roof has no flat or vertical end, unlike other designs, such as the gable roof.
The construction of hip roofs involves framing with a ridge board at the topmost point where different faces of the roof converge. Not only does this provide aesthetic appeal, but it also enhances structural integrity.
The continuous slope offered by this roofing style is especially beneficial in areas prone to high winds or heavy snowfall.
Mansard
Originating from French architecture, the Mansard roof, or a French or curb roof, offers an intriguing mix of design elements. Resembling a hip roof but with the addition of a steeper lower slope on all four sides, its unique shape commands attention.
This style is so iconic that even internationally renowned buildings such as the Louvre Museum in Paris proudly showcase it. The combination of hip and gambrel styles results in this distinctive design, leading to additional living or storage space within the structure itself.
Despite its elaborate structure, this common roof shape remains popular for those seeking functionality and aesthetic appeal in their building design.
Gambrel
Popular in Cape Cod-style homes, the Gambrel roof showcases two distinctive slopes on each side. The upper slope presents a shallower angle compared to the lower one, creating an intriguing visual contrast.
This type of symmetrical design also features in Mansard roofs – a more French take on this Dutch-inspired gambrel style. Traditionally linked with barn structures and classic Dutch architecture, it’s not just unique but highly practical, offering ample interior space due to its steep, sloping angles.
Flat
Often considered completely level, flat roofs still require a slight slope for sufficient water drainage. They are usually seen in homes with limited flat surface area combined with other roof designs, such as gable or hip roofs.
Roofing materials commonly used for flat structures include EPDM rubber, TPO, PVC roofing membranes and tar. Despite being referred to as shallow sloped roofs, each type boasts its unique advantages.
Comparatively flat surfaces allow more functional use of space through rooftop gardens or solar panel installation. Therefore, this could make them an appealing choice depending on the architectural requirements of your building project.
Low Slope
Low-slope roofs are often preferred for their simplicity in design and construction. The key attribute to these roofs is a pitch that’s generally 4 in 12 or less, making them easier to construct due to the need for fewer roofing materials.
Despite the low slope, all roofs should have some degree of gradient for effective water drainage.
Shed homes typically incorporate steeper slopes than what is found on many other low-slope designs. This aids in efficient water runoff, which helps prevent structural damage over time.
Though they might resemble flat roofs from afar, shallow slope roofs have a slight angle that allows rainwater to flow off safely into gutters and downspouts. These attributes make it integral within the roofing industry, as it balances both practicality and aesthetic appeal.
Lesser Known Roof Shapes

A-Frame
The A-Frame roof takes its name from its distinctive shape, offering a unique design element to any structure. It resembles the alphabet ‘ A ‘ with symmetrical, angled sides that come together at the peak.
This design is commonly implemented in triangular-shaped homes structured with a series of rafters or trusses. It’s not unusual to spot A-frame roofs on barns, farmhouses and log cabins due to their traditional aesthetic appeal.
Many Dutch Colonial or Georgian-style homes also feature this popular roof shape for an added architectural interest.
Saltbox
Saltbox houses are a unique and charming example of Colonial architecture, particularly in New England. Named after the design of kitchen salt storage boxes from the Colonial era, saltbox roofs have a distinct shape.
These roofs are long and rectangular, with the ridge running along the long end. One side of the roof is flat with a slight slope, while the other has a more “lean-to” structure.
This asymmetrical design adds character to traditional houses and is often seen as an architectural highlight in historic neighbourhoods.
Bonnet
Bonnet roofs are a lesser-known roof shape characterized by double slopes. The lower slope is set at a less steep angle than the upper slope, giving it a unique aesthetic appeal. Sometimes called kicked-eaves roofs, bonnet roofs add style to a house and offer shade and protection from the elements.
It’s important to note that constructing a bonnet roof can be more expensive than other roof types due to its complex design.
In conclusion, choosing a bonnet roof might be worth considering if you’re looking for a roof style that stands out and provides both visual appeal and functionality. Remember that this option may come with an additional cost, but the unique look and added shade make it an attractive choice for many homeowners.
Monitor
A monitor roof is a unique and lesser-known shape that adds an extra level to a building. This raised section runs parallel to the primary roof and creates a ‘second’ roof.
It is often equipped with windows or skylights, allowing natural light to enter the space below. Not only does this provide ample sunlight, but it also allows for additional ventilation and airflow by installing vents or louvres.
The design of a monitor roof can maximize usable space within a building, making it perfect for storage or creating extra work areas. When it comes to construction, monitor roofs can be made using various materials such as asphalt shingles, metal, or even glass.
Butterfly or V-Roof
The Butterfly or V-Roof is a lesser-known roof shape characterized by its unique V-shaped design with two raised wings that meet in the middle. Also known as a split gable roof, this architectural style offers an attractive and distinctive look to any building or structure.
The roof consists of two slopes that slope downward from the centre, resembling a butterfly’s wings. Commonly used in high-rise buildings and considered a design feature in modern architecture, the Butterfly or V-Roof adds an element of sophistication and elegance to any roofing system.
Arched
Arched roofs are known for their distinctive curved design, often seen in Gothic architecture and cathedral roofs. These roofs can range from low slopes to rounded peaks, giving them a unique look that stands out from other roof shapes.
Arched roofs can take on different forms, such as barrel vaults or vaulted designs, adding even more visual interest to the structure. Additionally, dormer windows with arched tops are another feature found in buildings with this type of roof shape.
Overall, arched roofs offer a striking aesthetic and can enhance the beauty of any building or structure they adorn.
Domed
Domes are a lesser-known roof shape that is considered crucial in architecture. These curved buildings have no corners or straight lines, giving them a unique and eye-catching appearance.
Domes evolved from the arch and are often used as ceilings or roofs. The semi-circle shape of a domed roof maintains the same structure all the way around, creating a sense of balance and harmony.
One famous example is the Cathedral of Santa Maria del Fiore, which boasts the largest masonry dome in the world. It took over 140 years to complete this impressive architectural feat.
