What is Roof Edge Trim?

Roof edge trim is a finishing component designed to protect and neaten the edges of flat or pitched roofing systems. Typically made from GRP (Glass Reinforced Plastic), aluminium, or plastisol-coated steel, roof edge trims help direct rainwater into gutters, prevent wind uplift, and offer a clean, professional aesthetic. These trims are essential for ensuring the long-term durability and weatherproof performance of any roofing installation.

Plastisol Coated Steel Edge Trim

These trims, notably from ULTRATRIM, are known for their robustness and corrosion resistance. Perfect for environments demanding longevity and strength, these trims ensure a clean finish to your roofing edges.

GRP (Glass Reinforced Plastic) Roof Edge Trim

Offered in a full range by RYNO, GRP trims are versatile and lightweight. These are ideal for projects requiring ease of installation without compromising on durability. Their range includes F2/F2L, F3/F3L, and F4/F4L options, each tailored for different edge profiles.

Aluminium Roof Edge Trim

Aluminium trims, including the AF3/AF3L and AF4/AF4L series, are known for their lightweight and rust-resistant properties. They are available in both internal and external trim types, making them suitable for various roofing scenarios.

External vs Internal Trims

• External Trims: Designed to provide a neat finish on the outer edges of the roof.
• Internal Trims: Best suited for providing a seamless finish at internal corners and joints.
• Colour Options: Several GRP trims like the A3, A4, and F6 series are available in multiple colours, allowing for aesthetic coherence with your roofing materials.

Specialised Trims

Aluminium Roof Edge External and Internal Angles (AA2/AA3): These are specifically designed for precise angle finishing.

AF2, AF5, AF6 Aluminium Internal Trims: These variants offer different dimensions like 45mm x 45mm, 110mm x 64mm, and 150mm x 64mm, catering to specific edge requirements.

Choosing the Right Trim

• Material Consideration: Match the trim material with your roofing for compatibility and longevity.
• Dimensional Fit: Ensure the size and profile of the trim aligns with your roof edge.
• Aesthetic Alignment: Select colour and finish based on the overall look of your building.

Benefits of Roof Edge Trim

• Weather Protection: Seals off roof edges from wind, rain, and water ingress.
• Prevents Uplift: Acts as a barrier against strong winds lifting roofing membranes.
• Clean Finish: Delivers a tidy, uniform look to roof edges and corners.
• Corrosion-Resistant: GRP and aluminium trims are long-lasting and rust-proof.
• Low Maintenance: No repainting or upkeep required — especially with GRP and plastisol-coated options.
• Versatile Aesthetic: Available in various sizes, profiles, and colours to suit different roof styles.

Applications of Roof Edge Trim

Roof edge trims are ideal for a wide range of roofing systems, including:

• Flat Roofs: To terminate the membrane and protect the perimeter.
• GRP/Fibreglass Roofing Systems: As an essential component in finishing off the edge cleanly.
• EPDM/Rubber Roofs: To secure the membrane and enhance water drainage.
• Commercial Buildings: For robust edge protection with steel trims.
• Domestic Projects: For garages, extensions, and garden buildings.

Whether you’re working on a new build, refurbishment, or DIY flat roof project, roof edge trims are a must-have for performance and style.

Installation Tips

• Measure & Cut: Select the correct trim profile (e.g., F2, F3, F6, AF2) based on roof depth and membrane type.
• Dry Fit First: Before applying adhesive or fixings, position the trims to ensure proper alignment.
• Secure in Place: Use compatible fixings — like polypins for GRP or stainless screws for aluminium — at recommended intervals.
• Use Matching Accessories: Internal and external corners, end caps, and joiners ensure a seamless finish.
• Seal Joints: For extra weatherproofing, use compatible sealants at joints and overlaps.
