Using Pedestals for Multi-Level Rooftop Terraces

Creating a stunning multi-level rooftop terrace is now easier than ever with the innovative use of pedestals. 

These versatile components are the key to transforming uneven or sloped surfaces into beautiful, functional outdoor spaces.

The Foundation of Multi-Level Terraces

Rooftops are rarely perfectly flat, which can pose challenges when designing outdoor areas. This is where pedestals shine.

The robust Raaft® steel pedestals are simple to install and provide ideal support for modular terrace systems.

They allow you to create level surfaces on varying heights, opening up a world of design possibilities.

Creating Multi-Level Spaces with Pedestals

With pedestals, you can effortlessly create distinct zones within your rooftop terrace:

• Elevated dining areas
• Sunken lounge spaces
• Tiered garden sections

This multi-level approach adds visual interest and maximises the functionality of your outdoor space.

Professional Considerations

For professionals, here are key considerations when designing multi-level rooftop terraces using pedestals:

Structural Integrity and Load Bearing

When planning a multi-level rooftop terrace, carefully assess the building's structural capacity:

• Calculate the total dead and live loads, including pedestals, decking, furniture, planters, and occupancy.
• Ensure the roof structure can support the added weight without compromising integrity.
• Consider load-spreading solutions to distribute weight evenly and protect insulation and waterproofing membranes.

Compliance with Building Regulations

Adhere to relevant building codes and fire safety standards:

• Familiarise yourself with Approved Document B for fire safety requirements.
• Specify BROOF T4 classified roof constructions where required.
• Use fully tested and certified terrace build-up systems to maintain compliance

Drainage and Waterproofing

Proper drainage is crucial to prevent water damage:

• Design the roof with adequate slope for water runoff.
• Utilise adjustable pedestal systems to raise the terrace surface above the waterproof membrane.
• Incorporate built-in slope correction features in pedestals to ensure a level finished surface

Creating Distinct Zones

Leverage the multi-level design to create functional spaces:

• Designate areas for dining, lounging, and landscaping.
• Use height differences to add visual interest and define separate zones.
• Incorporate planters and greenery to enhance the outdoor experience

Benefits of Pedestal Systems

1. Versatility: Pedestals can accommodate different surface materials, from porcelain tiles to composite decking, allowing for diverse design options
2. Easy Installation: The intuitive modular terrace system can be easily constructed in a simple three-step process, making installation quick and efficient
3. Adjustability: Height-adjustable pedestals ensure a perfectly level surface, even on significantly sloped rooftops
