How Raaft’s modular roof terrace system speeds up commercial projects

When it comes to commercial construction, time is money, and every day of delay can mean lost revenue. That’s why developers, architects and contractors are turning to smarter building solutions to stay on schedule.
One solution for commercial roof terraces is Raaft’s modular roof terrace system. Designed with efficiency in mind, this innovative system streamlines installation, reduces on-site labour and delivers high-quality results.
We will explore how our modular approach is transforming rooftop projects and helping commercial developments move faster to completion.
Why speed matters in commercial construction
Speed is crucial in commercial construction for many reasons, including:
- Profitability: Faster project completion means lower labour costs and less time spent on site.
- Client satisfaction: Speed allows contractors to deliver on time, leading to generally happier clients.
- Safety and efficiency: Faster progress reduces downtime caused by delays or unforeseen circumstances, improving overall efficiency. A well-paced project can also contribute to improved safety as it minimises the need for rushed work and potential accidents.
The challenges of traditional roof terrace installation
Traditional roof terrace installations can be time-consuming, labour-intensive and full of logistical hurdles. These systems often require:
- Complex substructures
- Custom fabrication
- Precise coordination between multiple trades
All of these can increase the risk of delays and cost overruns.
Weather conditions can also play a disruptive role. Since many traditional installations depend on dry, stable conditions for accurate levelling and material handling, even short periods of bad weather can halt progress.
Uneven surfaces or structural limitations may require time-consuming adjustments or bespoke solutions. Adding to the challenges of traditional roof terrace installation.
While traditional methods can yield strong results, they often demand more time, coordination and contingency planning than most commercial timelines can afford.

What makes Raaft’s system different?
Raaft’s module roof terrace system stands apart by offering a comprehensive, screwless solution that addresses the unique challenges of rooftop construction. Here is how it is different:
1. Modular, screwless installation
The system uses a modular design with interlocking aluminium joists and bracing struts, eliminating the need for screws. This approach not only simplifies installation but also facilitates easy maintenance and future modifications.
2. Adjustable and lightweight support
Raaft’s Preventa pedestals are height and slope-adjustable, accommodating uneven roof surfaces. Made from corrosion-resistant steel, they provide a robust yet lightweight foundation. This ensures stability without adding excessive weight.
3. Fire and wind resistant
All core components, including pedestals and joists, are constructed from BRoof (t4) fire-rated materials. The system is designed to withstand wind uplift, with secure locking clips or high-strength adhesives tested to meet UK wind conditions.
4. Enhance drainage and service access
The design incorporates efficient water drainage solutions, preventing pooling and potential damage. The secured decking allows for easy removal, ensuring unobstructed access to underlying services for maintenance.
5. Aesthetic and functional versatility
Raaft offers a range of surface options, including Atria porcelain tiles, available in various styles and finishes. Complemented by steel planters and furniture, the system provides both aesthetic appeal and functional flexibility.

Design flexibility without the delay
Whether you’re working with complex layouts, tight corners or specific aesthetics goals, Raaft’s system adapts easily. Its wide range of finishes, surface options and modular configurations give you the creative, design freedom you need. Without compromising project timelines.
In addition to decking and tiles, Raaft’s integrated planters allow for seamless incorporation of greenery into the design. These planter systems not only enhance visual appeal but also support biophilic design principles, helping create more inviting, functional rooftop spaces with minimal structural disruption.
Reduced on-site labour and complexity
The simplicity of the Raaft roof terrace system minimises the need for large, specialised installation teams. With fewer materials to handle, lightweight components and clear modular logic, installation is straightforward.
Long-term benefits of Raaft’s roof terrace system
Beyond speeding up installation, Raaft’s roof terrace system delivers long lasting advantages that continue well after project completion.
- Low maintenance and easy access: Thanks to its gravity-secured design, surface materials can be lifted easily for inspections or repairs without damaging the structure. This makes routine maintenance and access much simpler, saving time and money over the life of the terrace.
- Durability in harsh conditions: Raaft components are engineered to withstand extreme weather, moisture and UV exposure. Designed to handle varied environmental stresses, Raaft’s system also ensures predictable weight loading. This is critical for maintaining roof integrity over time.
- Sustainability and compliance: With fire-rated, non-combustible materials and designs that support rainwater drainage and green infrastructure, Raaft helps clients meet modern sustainability standards and building regulations.
