Product Information

Full details

The Rubbertech ROOFROLL SLATE is a premium flashing solution designed for professional roofers and DIY enthusiasts who need a durable, lightweight alternative to traditional lead. It provides a reliable waterproof seal for complex roofing areas like chimneys and abutments while maintaining an aesthetic slate finish; however, users should note that while it mimics lead in appearance and flexibility, it is a synthetic EPDM-based product that requires specific adhesive or mechanical fixing methods for long-term securement.

FAQs

Can ROOFROLL SLATE be painted?

It is not recommended to paint the product, as the textured slate finish is designed to be color-fast and durable on its own.

Is this product safe for drinking water collection?

Yes, ROOFROLL SLATE is chemically inert and safe for use on roofs where rainwater is collected for garden use or irrigation.

What tools do I need for installation?

You will need a pair of heavy-duty snips, a retractable utility knife, and a soft dressing tool or roller.

How does it compare to lead in terms of longevity?

It offers an expected service life of over 40 years, which is competitive with traditional lead when installed correctly.

Can I install this in wet weather?

No, the surface must be clean and dry to ensure a proper bond, especially if using adhesive sealants.

Is this roll suitable for flat roofs?

It is primarily designed for pitched roof junctions, but it can be used for detailing on flat roof upstands.

Troubleshooting

Material not adhering to the substrate

Ensure the surface is dry and free of oil or dirt. Use an EPDM-compatible adhesive if mechanical fixings are insufficient.

Difficult to dress into tight corners

Warm the material slightly if working in very cold temperatures, or use a wider dressing tool to spread the pressure across the mesh core.

Water leakage at junctions

Check that the top edge is correctly tucked into the mortar joint or secured with a cover flashing or sealant to prevent water ingress.

Pros and Cons

Pros

  • Significantly lighter than traditional lead, reducing labor strain.
  • Highly flexible for complex geometries such as dormers and junctions.
  • Excellent resistance to UV rays and extreme weather patterns.
  • Non-toxic material composition is safer for installers and the environment.
  • No scrap value, making it less prone to theft on job sites.

Cons

  • Requires specific installation techniques compared to traditional lead welding.
  • The slate finish may fade slightly over several decades of intense exposure.
  • Not suitable for applications requiring heavy-duty weight bearing.
  • Must be used with manufacturer-recommended sealants or fixings.

Setup, Compatibility & Care

Installation of ROOFROLL SLATE is straightforward but requires attention to surface preparation. Ensure that all surfaces are clean, dry, and free from dust, debris, or oily residues before application.

  1. Measuring: Measure the required length and cut with heavy-duty shears or a utility knife.
  2. Dressing: Use a soft-headed dressing tool or a gloved hand to mold the material into the shape of the tiles or masonry.
  3. Securing: If required by the specific roof design, utilize mechanical fixings or a recommended EPDM-compatible flashing adhesive along the upper edges to prevent wind lift.
  4. Maintenance: Periodically inspect for any loose edges after extreme weather events. The material generally requires no maintenance, but clearing debris from the flashing area helps maintain the integrity of the seal.
