EPDM Kerb Edge Trim | 2.5m Length | Raised Edge | Aluminium

EPDM Kerb Edge Trim | Raised Perimeter Profile for Flat Roofs

Create a professional, watertight perimeter on your flat roof with this powder-coated aluminium kerb edge trim. Designed specifically for EPDM rubber roof installations, this raised edge profile retains water on the roof surface, directing it towards designated drainage points rather than cascading over the edge.

🔧 Specifications

✅ Key Benefits

• Water Management – Raised edge prevents uncontrolled water run-off
• Directs Drainage – Water flows to designated outlets, not over edges
• Professional Finish – Clean, defined roof perimeter appearance
• Durable Aluminium – Corrosion-resistant, maintenance-free construction
• Colour Matched – Powder-coated to complement EPDM membrane
• Easy Installation – Mechanical fixings with adhesive membrane bond
• Long Lasting – Aluminium construction for decades of service

🏠 Perfect For

• Flat roof perimeters without guttering
• Roof areas requiring water retention for controlled drainage
• Extension and garage roofs
• Garden rooms and home offices
• Commercial flat roof installations
• Roofs with internal drainage outlets
• Upgrading felt roofs to EPDM systems

📐 When to Use Kerb Edge vs Drip Edge

Choose kerb edge trim when your roof has internal drainage (outlets/downpipes through the roof) or where you need to prevent water cascading over edges. Choose drip edge trim when water should discharge into external guttering.

🛠️ Installation Guide

1. Measure Perimeter – Calculate total length required plus 10% for cuts and overlaps
2. Position Trim – Place along roof edge with raised section facing inward
3. Mark & Drill – Pre-drill fixing holes at 300mm centres
4. Secure with Fixings – Use appropriate fixings for your deck material
5. Overlap Joints – Overlap trim sections by 50mm minimum
6. Seal Overlaps – Apply sealant between overlapping sections
7. Bond Membrane – Adhere EPDM membrane to trim using contact adhesive
8. Roll & Seal – Use seam roller to ensure full adhesive bond

📦 Calculating Quantities

Each piece is 2.5 metres long. To calculate how many you need:

1. Measure total perimeter length in metres
2. Divide by 2.5 (length per piece)
3. Add 10% for cuts, overlaps, and waste
4. Round up to whole number

Example: 15m perimeter ÷ 2.5 = 6 pieces, +10% = 7 pieces needed

🔗 Complete Your EPDM System

For a professional installation, combine with:

• EPDM Membrane – Main roofing surface
• EPDM Corner Pieces – Pre-formed corners for neat finishes
• EPDM Drip Edge – For edges with external guttering
• EPDM Wall Flashing – Where roof meets walls
• EPDM Contact Adhesive – For all bonding

📋 Technical Properties

💬 Frequently Asked Questions

Q: How many pieces do I need for a 4m x 3m roof?
A: Perimeter = 14m. Divide by 2.5m = 5.6, add 10% = 6.2. Order 7 pieces to be safe.

Q: Can I cut this trim to size?
A: Yes, aluminium cuts easily with a hacksaw or mitre saw. Deburr cut edges before installation.

Q: What fixings should I use?
A: Use stainless steel screws for timber decks, or appropriate fixings for concrete/ply. We recommend 40mm screws at 300mm centres.

Q: Is the anthracite colour the same as RAL 7016?
A: Very close match to RAL 7016 (anthracite grey), ideal for coordinating with modern window frames and cladding.

Q: Can I use this with other membrane types?
