Choosing a unique roof style is the easiest way to improve the overall appearance of any building. Such a significant design is the sawtooth roof, which allows sufficient sunlight to enter a building without creating excess heat. Before the usage of electric lights, saw-tooth roof design was the primary choice for industrial buildings and factories.
This design comprises a series of ridges with dual pitches on either side. It became a popular choice for large industrial buildings.
There is so much to learn about saw-tooth roof style, which is explained in the below:
Types of Saw-tooth Roofs
Saw-tooth roofs are classified into various types, each with its own features and style. Herewith, some of the popular types have been explained below:
Single Sawtooth Roof
It is a series of skillion roofs containing sloping in one direction with vertical surfaces. It provides additional storage space for the existing buildings or structures. This roof type is particularly suitable for a taller wall. It transmits natural light into the building or factory and makes space brighter without any electrical lights.
Multi-Sawtooth Roof
The multi-sawtooth roof is characterised by a series of triangular shapes that are similar to the teeth of a saw. This design accumulates the features of glass panels, allowing natural light to enter the structure. It provides excellent ventilation, as the heated air can escape through the gaps in between the slopes.
Tips on Building a Sawtooth Roof
A sawtooth roof is made with sturdy materials like concrete, wood, or metal. Builders often consider this roof style during construction if they prefer natural light and ventilation as the major sources.
The beams of the roof are far longer and provided with extra reinforcement work. The dead weight of the roof is higher than the live weight. For achieving additional support, builders chase steel bracing to handle the roof’s open parts. They are sturdy and long-lasting.
One of the straightforward ways to frame this roof is by creating a series of ridges and valleys. Unlike asphalt shingles, the building structure is typically weak and often requires metal or slate to provide extra support.
Each section has a roof piece, which is titled at the right angle of 15 degrees. The gutters are another important factor to consider. Ensure they are strong enough to drain water when it heavily rains. If you would like to install box gutters, maintain them regularly to prevent them from falling or leaking.
At last, you must take extra concern about the snow fall on your sawtooth roof. It may lead to the formation of mold growth around the windows.
Applications of Sawtooth Roof in Construction
Due to its functional and aesthetic benefits, sawtooth roofs have become a recognized architectural choice. Here are some significant applications that you need to know:
Industrial Buildings and Factories
Sawtooth roofs provide a unique architectural style where the building requires natural light and ventilation. The glazed panels placed on the steeper slopes allow light deeper into interior space. Additionally, the open gaps between the slopes reduce heated air and provide a constant air flow.
Modern Residential Architecture
A sawtooth roof adds a rustic and modern look to your residential homes. Their angular lines and geometric patterns make the overall appearance awe-striking. The primary reason to use it in the modern structure is offering airy interior space and bright light. However, the alternating slopes on the roof improve privacy for homeowners.
Commercial and Public Buildings
Sawtooth roofs are often found in retail spaces due to their inviting atmosphere. The natural light penetrates inside the space to highlight products and draw customers’ attention. With ample natural light and a ventilated workspace, shops can experience increased productivity.
Advantages of Sawtooth Roofs
Let’s see the benefits offered by sawtooth roofs to buildings, such as:
- Penetrates Natural Light: Glass panels are the primary component of a sawtooth roof, which allows natural light and ventilation on the inside. These panels not only look great by look but also protect buildings from ultraviolet radiation.
- Provides Extra Space: Due to its lofty ceilings, buildings can avail spacious interiors. This is a major benefit offered by the sawtooth roof to the massive structures.
- Creates Unique Design: Sawtooth roofs are functional and aesthetic appeal, which can quickly improve the look of any building. The designs are eye-catching and unconventional, perfect for modern, open-concept homes.
- Energy Conservation: When a sawtooth roof has been installed correctly, it keeps a home warm in winter and vice versa in the heat of summer. Along with a natural light, it improves ventilation inside the home.
Disadvantages of Sawtooth Roof
- Expensive: The construction of a sawtooth roof is more expensive than other roofing styles because of its complex design and increased material requirements. Undoubtedly, choosing an intricate design will raise your budget range, which typically involves material cost and additional labor cost.
- Higher Maintenance: Sawtooth roofs may tend to rust. It is often made of metal and when the water or snow fall is not shed off easily, it requires high maintenance. This means that you need to replace or fix roofing often. During maintenance, it is important to note down the quality of materials used to replace older ones.
Materials Used for Sawtooth Roofs
Sawtooth roofs are constructed of various materials that provide excellent weather resistance, aesthetic appearance, and structural integrity.
Metal Roofing Sheets
Metal roofing is an ideal choice for sawtooth roofs, known for its exceptional durability and longevity. They are available in various materials, including copper, steel, and aluminum, each having its own properties and appearance. Metal roofing is extremely resistant to weather conditions, corrosion, and rust formation.
Glass Panels
Glass panels improve energy efficiency by allowing natural light to enter the building. It creates a modern and rustic look to any structure with increased ventilation inside. The energy consumption for artificial lighting is reduced, and no heat can be experienced.
Concrete and Timber Framework
This is the most commonly used framework, providing increased stability and structural support to the building. Both materials are recognised for their durability and longevity, providing unique architectural styles from modern to traditional structures.
Why do factories have sawtooth roofs?
Factories have sawtooth roofs to maximize natural light and ventilation. The design allows sunlight to enter through the vertical glass panels while minimizing direct heat, improving energy efficiency and working conditions.
Final Thoughts
Sawtooth roofs are aesthetically pleasing and they provide natural light to highlight the interiors. They were initially widely used in factories, but later, their energy efficiency gained popularity among households. If you plan on constructing any commercial or residential building, then consider this roofing style a priority.
