Roof Trims

Roof trims are an essential finishing component for any flat roofing project, helping to create a clean, weatherproof edge while protecting vulnerable areas from water ingress and long-term damage. Designed for use with felt, asphalt, liquid, EPDM, and single-ply membrane systems, roof edge trims provide both functional performance and a professional finish.

At Gutter Centre, you’ll find a comprehensive range of roof trims, including high-performance aluminium roof trims and durable GRP roof trims, suitable for both domestic and commercial applications.

What Are Roof Trims?

Roof trims are installed along the perimeter of a flat roof to seal edges, direct rainwater, and prevent water penetration. They play an important role in maintaining the integrity of the roofing system by protecting edges, corners, and joints from exposure to the elements.

Common applications include:

  • Flat roofs on extensions and garages
  • Commercial roofing systems
  • New builds and refurbishment projects
  • Fibreglass (GRP) roofing systems

Aluminium Roof Trims

Aluminium roof trims are a popular choice for modern flat roofing systems due to their strength, durability, and sleek finish.

  • Corrosion-resistant and unaffected by atmospheric pollution
  • Lightweight yet strong, making them easy to install
  • Long-lasting and low maintenance
  • Available in mill finish, anodised, or powder-coated colours
  • Suitable for felt and EPDM roofing systems

Aluminium trims are typically extruded for precision and consistency, delivering a reliable, professional edge detail that performs well in all weather conditions.

GRP Roof Trims

GRP roof trims (Glass Reinforced Plastic) are specifically designed for fibreglass and liquid roofing systems, offering exceptional durability and flexibility.

  • Highly durable and impact-resistant
  • Lightweight and easy to handle on-site
  • Non-corrosive and UV-resistant
  • Low thermal expansion, reducing the risk of cracking or leaks
  • Provides a seamless, watertight finish

GRP trims are manufactured using a combination of polyester resin and glass fibres, resulting in a strong, long-lasting solution ideal for exposed roof edges.

Types of Roof Trims Available

Our range of roof trims includes a variety of profiles to suit different roofing applications. From drip edge trims that direct water away from the roof edge, to corner trims that ensure a neat finish at internal and external angles, to flashing trims that provide a weatherproof seal at roof junctions.
