A sawtooth roof is a unique and functional design that can add visual interest to any building. It's characterized by a series of symmetrical, triangular projections that resemble a sawtooth pattern.
This design offers several benefits, including increased roof area and improved ventilation. The sawtooth roof's asymmetrical shape allows for larger windows and clerestory windows, which can bring in natural light and reduce the need for artificial lighting.
The sawtooth roof's design also makes it ideal for use in climates with high snowfall or heavy rainfall, as the triangular projections can help to shed water and snow.

What Is a Sawtooth Roof?
Sawtooth roofs are made up of a row of ridges that have two different pitches on each side, creating a unique shape reminiscent of saw teeth.
These roofs have many parallel roofs that line up to make the shape of saw teeth, with one slope being steeper than the others.

The higher parts of these roofs usually have windows to allow for a lot of natural light.
Sawtooth roofs are popular on factories and other large industrial buildings, and some even resemble a series of skillion roofs.
People choose this roof type mainly to let more natural light into a room while reducing glare and keeping heat out.

Roof Definition
A sawtooth roof is a unique type of roof that features a row of ridges with two different pitches on each side. This design creates a series of parallel roofs that line up to resemble saw teeth.
The higher parts of these roofs typically have windows to allow for plenty of natural light.
Sawtooth roofs are commonly found on large industrial buildings, such as factories. Some of these roofs even resemble a series of skillion roofs.
One of the main reasons people choose sawtooth roofs is to reduce glare and keep heat out.
History of Sawtooth Roofs
Sawtooth roofs have been around since 1827 when they were reportedly first designed by British architect and engineer William Fairbairn.
Initially, sawtooth roofs were intended for power-weaving purposes and didn't become popular until the 20th century.
During the Industrial Revolution, companies greatly benefited from these roofs because of the additional light they provided.
Artificial lighting eventually made sawtooth roofs less necessary, causing them to fall out of favor.
These rooftop styles made a comeback in the late 20th century as eco-friendly commercial construction prioritized natural lighting.
The optimal number of sawtooth roofs is three, which was a key design element in their original purpose.
Sawtooth roofs were once only seen in factories and mills, but their environmental friendliness made them popular in homes as well.
Advantages and Benefits
Sawtooth roofs offer a range of advantages and benefits that make them a popular choice for buildings.
Sawtooth roofs allow for efficient use of headroom and floor space, making them ideal for industrial and manufacturing buildings. They provide maximum headroom compared to flat roofs.
The sawtooth shape of the roof lets in plenty of natural light, reducing the need for artificial lighting and creating a pleasant working environment for people inside a building or factory.
Some of the key benefits of sawtooth roofs include:
- Providing more natural light
- Creating extra space with lofty ceilings
- Accommodating the installation of solar panels
- Conerving energy by insulating against cold in winter and keeping air conditioning costs down in the summer
Reasons for a Roof
A sawtooth roof lets in plenty of natural light, alleviating issues like overheating in an industrial unit.
The sawtooth shape of the roof is designed to provide passive heating and cooling, making it a more efficient choice.
Sawtooth roofs have increased in popularity due to their ability to provide sufficient lighting in enclosed areas.
Natural daylighting refers to using windows and skylights to bring in natural light, creating a pleasant working environment.
It helps with other issues, including heat, at the same time, making it a great solution for industrial units.
Pros
Sawtooth roofs are a great choice for industrial and manufacturing buildings, providing natural light and heat control. Before electric light was common, sawtooth roofs were the primary light source.
Sawtooth roofs allow for efficient use of headroom and floor space, making them ideal for large structures. They also provide maximum headroom compared to flat roofs, which is a major benefit for buildings with high ceilings.
The sawtooth shape of the roof lets in plenty of natural light, which can help alleviate issues like overheating in industrial units. This design also provides passive heating and cooling, making it an energy-efficient option.
Sawtooth roofs have a unique design that can quickly improve the look of any building. They are perfect for modern, open-concept homes because of their unconventional and eye-catching design.
Here are some of the key benefits of sawtooth roofs:
- Provides more natural light: Glass panels are a standard component of sawtooth roofs, allowing abundant natural light to flood the inside.
- Creates extra space: This roof style allows for spacious interiors due to its lofty ceilings.
- Energy conservation: When constructed correctly, a sawtooth roof insulates against cold in winter and keeps air conditioning costs down in the heat of summer.
- Accommodates installation of solar panels: Sawtooth roofs are ideal for installing solar panels, which can significantly reduce energy costs.
Frequently Asked Questions
Which direction should a sawtooth roof face?
A sawtooth roof should face north to allow sunlight in while keeping excess heat out. This design was particularly useful for factories and industrial buildings before the use of electric lighting.
