Roofing Trims

Roofing trims provide the essential finishing touches that protect vulnerable edges, junctions, and verges from weather ingress while delivering a clean, professional appearance. These components work alongside your main roofing materials to seal gaps, direct water away from critical areas, and ensure long-lasting performance across pitched and flat roof applications.

Our Range of Roofing Edge and Verge Trims

McMahons stocks a comprehensive selection of trim profiles to suit every roofing system and material type.

  • PVC cloaking profiles - roofline cloaking trim sections in 65mm and 95mm widths, 2.5m lengths, for covering the gap between the fascia board and the wall at the roofline, providing a neat weatherproof finish and preventing bird and pest ingress at the eaves.
  • PVC window boards - exterior PVC window board trims in 175mm and 225mm widths, 2.5m lengths, for finishing window reveals and external sill areas as part of a complete roofline and eaves installation.

For a complete roofing solution, browse our full Roofing & Ventilation Products range, including Fascia & Soffit options that complement your edge detailing.

When selecting roofing trims, consider the pitch of your roof, the primary covering material, and exposure to prevailing weather. Dry fix systems suit most modern installations, while traditional lead or mortar details may be required for heritage properties or conservation areas. Always check that profiles match your tile or slate manufacturer's specifications.
