Using Sedum Roof Trays for Instant Green Roof Coverage in the UK

Why Sedum Roof Trays Are Ideal for Quick Green Roofs

Sedum roof trays are pre-grown, modular panels that allow for fast installation and instant coverage. They provide:

• Immediate visual impact on rooftops

• Sustainable and low-maintenance roofing solutions

• Enhanced biodiversity by attracting pollinators

• Energy savings through natural insulation

• Stormwater management by absorbing rainfall

Trays are especially suited to small to medium roofs, including garden buildings, extensions, hotels, and country estates.

Step 1: Planning Your Sedum Roof Tray Installation

• Measure roof area: Calculate total trays required for full coverage

• Assess roof load capacity: Trays are lightweight but ensure the structure can support them

• Choose sedum mix: Options for local UK climate, wildlife-friendly, or aesthetic preference

• Plan irrigation and drainage: Rainwater often suffices, but consider drip irrigation for larger roofs

Tip: Modular trays allow easy replacement or expansion in the future.

Step 2: Preparing the Roof

• Check waterproofing: Existing roofing membrane must be intact

• Install root barrier: Protect the membrane from root penetration

• Lay drainage layer: Prevent waterlogging and ensure proper sediment drainage

• Add growing substrate: Lightweight mix specifically for sedum and modular trays

Step 3: Installing the Sedum Trays

1. Position trays on the prepared substrate in interlocking rows

2. Adjust trays at edges for neat alignment and coverage

3. Fill any gaps with extra sedum plugs or substrate

4. Water lightly after placement to settle the plants

5. Inspect weekly for any displaced trays until the plants establish

Pro Tip: Install from the bottom edge upwards on sloped roofs for stability.

Step 4: Maintaining Your Sedum Roof

• Watering: Only during dry periods, sedum is drought-tolerant

• Weeding: Rare, as sedum competes strongly with weeds

• Inspection: Check trays after storms or high winds

• Seasonal care: Remove fallen leaves and ensure drainage channels are clear
