Designing a rooftop terrace is an exciting venture, offering the promise of a private outdoor sanctuary to relax and entertain. However, amidst the excitement, it's essential to consider both cost-effective strategies and the importance of investing in quality solutions for long-term enjoyment.

In this blog, we’ll explore how to strike the balance between cost-effective solutions and the significance of investing in high-quality products by addressing common challenges while prioritising durability and practicality.

Roof Terrace Design Solid Foundation

Before diving into the aesthetic aspects, ensure that your rooftop terrace has a structurally sound foundation. Investing in proper waterproofing, drainage, and structural support will prevent future headaches and costly repairs. While this may seem like a significant upfront expense, it’s crucial for the longevity of your terrace and will save you money in the long run.

Raaft® Weight Loading Roof Terrace Design Solution

One concern with rooftop terraces is ensuring the structure can support the weight of furniture, people, and landscaping elements without compromising safety. To tackle this, a modular extruded aluminium system is a game-changer. Utilising interlocking joists and bracing struts, it creates a robust yet lightweight platform. Height-adjustable pedestals further support, stabilise, and level the platform, ensuring even weight distribution for maximum support.

Raaft® Wind Uplift Solution

Wind uplift can pose a significant threat to rooftop terraces, potentially dislodging decking or tiles and causing damage. Raaft®’s innovative solutions like discreet grooves in composite and porcelain decking, coupled with design-protected stainless steel and Nylon 12 RP anti-uplift clips, offer a secure fix. These clips seamlessly integrate into the groove, holding the decking or tiles firmly in place with minimal visibility, even in high winds.

Raaft® Water Drainage Roof Terrace Design Solution

Addressing water drainage is paramount for the health of your rooftop terrace. To combat water pooling, the Venice Clip offers a meticulously designed solution.

This discreet clip facilitates efficient water drainage from tiles, adhering to NHBC guidelines by ensuring water does not exceed 5mm in depth or 1m² in area within a one-hour timeframe. By implementing such solutions, you can safeguard your rooftop terrace against water-related damage and prolong its lifespan.

Raaft® Service Access Roof Terrace Design Solution

Accessibility for maintenance and servicing is another consideration often overlooked in rooftop terrace design. While the terrace system framework and gravity can suffice for holding decking and tiles in place, areas prone to strong winds may require additional measures.

Enter the anti-uplift clip system, available in tough nylon or stainless steel, providing extra security by aligning with grooves in decking and tiles, ensuring they remain firmly in the frame.

Raaft® Slope Corrector Roof Terrace Design Solution


Achieving proper slope for water drainage is essential to prevent pooling and water damage. Incorporating slope correctors into the design helps to ensure water flows away efficiently, reducing the risk of water-related issues.

Choose Low-Maintenance Rooftop Terrace Design Materials

Opt for materials that not only look great but also require minimal upkeep. Consider using composite decking, which mimics the look of wood but is more durable and requires less maintenance.
