MGN Builders Merchants offers a comprehensive selection of GRP Trims designed to support the integrity and finish of flat roof installations. GRP (Glass Reinforced Plastic) roofing trims are essential components in fibreglass roofing systems, helping ensure durability, effective water drainage, and a polished edge detail. Whether you are a professional roofer or undertaking a DIY roofing project, these trims play a vital role in giving structure to the roof's perimeter and transitions.
Every roofing layout has unique needs, and selecting the right GRP Roofing Edge Trims ensures both function and appearance are addressed. These trims are engineered to guide rainwater away from the roof and to provide a clean, defined finish along the edges. Some common types include:
Drip trims, used at the lowest edge to guide water into gutters
Upstand trims, ideal where the roof meets a wall
Corner trims, to connect adjoining trim sections seamlessly
The ideal trim choice depends on the shape of your roof, drainage points, and adjoining surfaces. Matching the right trim ensures a weatherproof seal and a neat, lasting finish.
Our range of GRP roofing trims includes a wide variety of profiles and sizes to suit different applications. These include grp roof trims for edges, grp wall fillet trim to create clean upstands against vertical walls, and GRP Angle Trim for precise corner detailing. All products are manufactured with weather-resistant, high-quality GRP materials designed for long-term performance on flat roofing systems. Whether you're sealing a roof edge or managing corner joints, you'll find reliable solutions within our GRP trims selection.
