Weatherproofing Rooftop Terraces with Steel Pedestals

Rooftop terraces offer an oasis in the urban jungle, providing a space to relax, entertain, and enjoy breathtaking views. However, creating a functional and durable rooftop terrace requires careful planning, especially when it comes to weatherproofing. Steel pedestals are an excellent solution for ensuring the longevity and stability of rooftop terraces, offering both structural support and protection against the elements.

In this guide, we'll explore the benefits of using steel pedestals for weatherproofing rooftop terraces and provide insights into their maintenance.

The Benefits of Steel Pedestals

At Raaft®, we offer adjustable steel pedestals made of zinc-coated steel, available in 6 height options for even load distribution, and stability.

• Structural Support: Steel pedestals provide robust support for various decking materials, including wood, composite, and porcelain tiles. They distribute the weight evenly across the surface, preventing uneven settling and potential damage to the rooftop structure.
• Weather Resistance: One of the primary advantages of steel pedestals is their resistance to weathering. Unlike traditional materials like wood or concrete, steel is highly resistant to moisture, corrosion, and temperature fluctuations, making it ideal for outdoor applications.
• Adjustable Height: Steel pedestals are designed with adjustable height mechanisms, allowing for precise levelling of the terrace surface. This feature is crucial for ensuring proper drainage and preventing water pooling, which can lead to moisture-related issues such as mould and rot.
• Versatility: Steel pedestals are compatible with a wide range of decking materials and can accommodate various design preferences and aesthetic styles. Whether you prefer the natural warmth of wood or the sleek look of porcelain tiles, steel pedestals offer versatility without compromising on performance.

How Steel Pedestals Help Weatherproof Rooftop Terraces

Steel pedestals play a crucial role in weatherproofing rooftop terraces by providing structural support and protecting the underlying structure from moisture and environmental damage. Here's how steel pedestals contribute to weatherproofing rooftop terraces:

• Elevated Support: Steel pedestals lift the decking material off the rooftop surface, creating a gap that allows for airflow and prevents water from pooling. This elevation helps to protect the waterproofing membrane underneath, reducing the risk of leaks and water damage to the building's structure.
• Corrosion Resistance: Steel pedestals are typically made from corrosion-resistant materials such as galvanised steel or stainless steel. These materials are highly durable and capable of withstanding exposure to moisture, rain, snow, and fluctuating temperatures without rusting or corroding. This corrosion resistance ensures the longevity of the pedestals and maintains their structural integrity over time.
• Adjustable Height: Steel pedestals often feature adjustable height mechanisms, allowing for precise levelling of the terrace surface. This adjustability is essential for ensuring proper drainage and preventing water from accumulating on the rooftop. By maintaining a slight slope, water can flow freely off the terrace, minimising the risk of water infiltration and moisture-related issues.
• Compatibility with Decking Materials: Steel pedestals are compatible with various decking materials, including wood, composite, porcelain tiles, and concrete pavers. This versatility allows homeowners and designers to choose the most suitable decking material for their rooftop terrace while still benefiting from the weatherproofing properties of steel pedestals.
• Easy Installation: Steel pedestals are relatively easy to install, making them an efficient solution for weatherproofing rooftop terraces. They can be quickly adjusted and secured in place, reducing installation time and labour costs. Additionally, their modular design allows for easy removal and replacement if necessary, simplifying maintenance and repairs.
• Long-Term Durability: Thanks to their robust construction and weather-resistant properties, steel pedestals offer long-term durability and stability for rooftop terraces. They can withstand the rigors of outdoor exposure, including UV radiation, extreme temperatures, and heavy foot traffic, without compromising their performance or structural integrity.

Steel Pedestals Maintenance Tips

1. Regular Inspection: Periodically inspect the rooftop terrace for any signs of damage or wear, paying particular attention to the condition of the decking material and the integrity of the steel pedestals.
2. Cleaning: Keep the terrace surface clean by regularly sweeping away debris and dirt. For more stubborn stains, use a mild detergent and water solution to gently scrub the affected areas.
3. Check for Drainage: Ensure that the terrace maintains proper drainage by clearing any debris or obstructions from the drainage channels and gutters. Improper drainage can lead to water accumulation and potential damage to the waterproofing membrane.
