Flat roofs are a popular choice for modern buildings, offering a sleek and contemporary look. One of the key features that can enhance the appeal of a flat roof is a flat roof lantern. These architectural elements not only add aesthetic value but also bring in natural light, creating a bright and airy interior space.
In this article, we’ll explore the process of constructing a flat roof with a focus on installing a flat roof lantern.
Setting Out the Joists
The first step in constructing a flat roof is setting out the joists. This involves marking the positions of the joists according to the specifications of the flat roof lantern. The joists are then positioned and secured in place using screws and bolts. This ensures that the structure is stable and able to support the weight of the roof.
Installing Perimeter Noggins and Floor Noggins
Once the joists are in place, the next step is to install perimeter noggins and floor noggins. Perimeter noggins are installed along the edges of the roof to provide additional support and stability. Floor noggins are installed between the joists to further strengthen the structure and prevent any sagging or bowing.
Installing Upstands and Trimmers
Upstands and trimmers are essential components of a flat roof lantern. Upstands are raised edges that are installed around the perimeter of the roof opening to create a barrier against water infiltration. Trimmers are beams that are installed around the edges of the roof opening to support the weight of the lantern.
Overboarding with Plywood
Once the structure is in place, the next step is to overboard the roof with plywood. Plywood is a durable and weather-resistant material that provides a solid base for the flat roof. It is important to use high-quality plywood that is suitable for outdoor use to ensure a long-lasting and secure roof.
Installing the Flat Roof Lantern
With the roof overboarded, the flat roof lantern can now be installed. The lantern is carefully positioned and secured in place, ensuring that it is level and aligned correctly. The edges of the lantern are then sealed to prevent water infiltration and ensure a watertight seal.
Choosing the Right Materials
When constructing a flat roof with a flat roof lantern, it’s important to choose the right materials. The quality of the materials will determine the durability and longevity of the roof. For the joists, it’s advisable to use pressure-treated timber that is resistant to rot and decay. Perimeter noggins and floor noggins should also be made from high-quality timber to ensure stability.
For the upstands and trimmers, materials such as metal or PVC can be used for added durability and weather resistance. When selecting plywood for overboarding, look for exterior-grade plywood that is designed for outdoor use. This type of plywood is more resistant to moisture and is less likely to warp or degrade over time.
Ensuring Proper Drainage
Proper drainage is crucial for a flat roof to prevent water pooling and potential leaks. When installing the flat roof lantern, ensure that the upstands are tall enough to provide adequate water runoff. Additionally, consider incorporating a slight slope into the roof design to encourage water drainage towards the gutters or drainage system.
Regular Maintenance and Inspection
Once the flat roof with a flat roof lantern is constructed, regular maintenance and inspection are essential to ensure its longevity. Inspect the roof regularly for signs of damage or wear, such as cracks, leaks, or sagging. Repair any damage promptly to prevent further issues.
Final Touches and Quality Checks
Once the flat roof lantern is installed, the final touches are made to ensure that everything is in place and secure. This includes checking the quality of the timber, making any necessary adjustments, and ensuring that all obstacles are accounted for. A final quality check is conducted to ensure that the roof meets all safety and structural standards.
