The Cromar GRP Roofing Fascia Drip Trim is an essential component for professional roofers and DIY enthusiasts working on GRP flat roofing systems, specifically designed to ensure effective rainwater runoff into the guttering. Its primary benefit is the creation of a watertight, reliable edge that protects the fascia and roof structure from water damage. While it offers a highly durable finish, users should note that precise installation and the use of correct fastening materials are mandatory to ensure the long-term integrity of the roofing seal.

The trim is made from GRP (Glass Reinforced Plastic), which is selected for its high strength and excellent resistance to weather and corrosion.
While ring shank nails are recommended for their holding power and flush fit, ensure any alternative fastener is corrosion-resistant and appropriate for GRP roofing.
This product is specifically designed for the lowest edge of a flat roof to facilitate drainage into guttering.
Generally, GRP trims do not require priming, but ensure the surface is clean and dry to allow for proper bonding with the GRP laminate system.
You can cut the GRP trim using a fine-toothed hacksaw or an angle grinder with a diamond blade, ensuring all safety precautions are followed.
Check that the support battens are correctly positioned and that 20mm ring shank nails have been driven firmly into the substrate.
Ensure the vertical leg of the trim is centered over the gutter and has not been bent out of alignment during the roofing process.
To install the drip trim, first ensure the roof edge is smooth and free from debris. Position the trim so the vertical leg sits squarely in the center of the guttering. Secure the trim using 20mm ring shank nails through the horizontal flange into the roof deck. It is recommended to apply a small amount of professional-grade sealant beneath the flashing if required by your specific GRP system manufacturer. Maintenance is minimal; periodic checks during gutter cleaning should be performed to ensure the nails remain secure and the GRP material shows no signs of mechanical impact or cracking.
