Full details

The Cromar GRP Roofing Fascia Drip Trim (90mm x 90mm) is designed for professional roofers and DIY enthusiasts who need to ensure effective rainwater management at the eaves of a roof. By creating a reliable bridge between the roof edge and the guttering, this component prevents water ingress and protects fascia boards, though it requires precise measurement and specific fastening techniques to ensure a watertight installation.

FAQs

What tools are needed for installation?

You will need a hacksaw or fine-tooth saw for cutting, a hammer for the ring shank nails, and a measuring tape.

Can I use screws instead of ring shank nails?

Ring shank nails are recommended for better hold in the timber, but if using screws, ensure they are stainless steel and have a flat head to prevent interference with the roof covering.

Does the GRP trim need to be painted?

No, GRP is inherently weather-resistant and designed to withstand exposure without the need for additional painting or sealing.

Can this trim be used on curved roof edges?

This trim is rigid and designed for straight runs; it is not suitable for tight curves without specialized cutting and professional fabrication.

How do I overlap multiple lengths?

Overlap the lengths by at least 50mm and apply a suitable roofing sealant between the overlapping sections to maintain a waterproof seal.

Troubleshooting

Trim is not sitting level in the gutter

Adjust the support battens beneath the trim to ensure the vertical leg hangs correctly in the center of the gutter.

Water is dripping behind the gutter

Check that the drip edge has sufficient overhang and that the fixings are flush, ensuring no gaps exist between the roof felt and the trim.

Pros and Cons

Pros

  • Resistant to corrosion and rot
  • Provides a clean, professional finish to the roof edge
  • Simple to cut and customize for specific roof lengths
  • Compatible with standard guttering systems

Cons

  • Requires professional-grade fasteners for optimal performance
  • Needs careful alignment to ensure proper drainage angle
  • Brittle if handled roughly before installation

Setup, Compatibility & Care

To install the drip trim, align the unit along the lowest edge of the roof. Secure the trim to the roof deck using 20mm ring shank nails, ensuring they are spaced evenly to prevent warping. The vertical leg must be positioned directly over the center of the gutter system.

Care instructions involve regular inspections during your annual roof maintenance check. Ensure that no debris or moss is blocking the transition from the roof edge to the gutter, as this can cause water to overflow or sit against the trim. If cleaning is required, use a soft-bristled brush and mild soapy water to remove sediment buildup; avoid harsh chemical cleaners that might degrade the GRP composite.
