Using Pedestals for Multi-Level Rooftop Terraces

The Foundation of Multi-Level Terraces

Rooftops are rarely perfectly flat, posing challenges for terrace design. Raaft® steel pedestals are simple to install and provide ideal support for modular terrace systems, allowing you to create level surfaces across varying heights and unlocking creative design possibilities.

‍

Creating Multi-Level Spaces with Pedestals

Pedestals make it possible to define distinct zones on your terrace:

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

This multi-level approach adds visual interest while maximising functionality.

Professional Considerations

Structural Integrity and Load Bearing

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

‍

Compliance with Building Regulations

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

‍

Drainage and Waterproofing

• Design roofs with sufficient slope for water runoff.
• Use adjustable pedestals to raise terrace surfaces above waterproof membranes.
• Incorporate slope-correction features for level finished surfaces.

‍

Creating Distinct Zones

• Allocate areas for dining, lounging, and landscaping.
• Use height differences to define zones and add visual appeal.
• Integrate planters and greenery for a more engaging outdoor experience.
