Roof Flashing Plate Ricom Zorro DN100-125 steel – roof penetration cover for DN100–DN125

Ricom Zorro DN100-125 steel roof flashing plate provides a fitted sealing solution for round duct or pipe penetrations with diameters from DN100 to DN125. Designed as a cover and sealing flange for chimney, ventilation and exhaust pipe installations, the plate is made from steel to withstand weather exposure and provide a durable interface between the pipe and the roofing surface. The product fits common residential and light-commercial roofing materials and is intended to prevent water ingress and wind-driven debris from entering at the penetration point.

Advantages

The steel construction delivers corrosion resistance and mechanical strength suitable for outdoor roof use. The adjustable inner collar accommodates pipes within the DN100–DN125 range, enabling a snug fit without the need for custom fabrication. The flat base flange offers a continuous contact surface for roofing sealants and fasteners, supporting a reliable waterproof connection. Compatibility with multiple roofing types simplifies installation across different roof pitches and materials.

Suitable for

• Sealing chimney pipe penetrations
• Ventilation and exhaust duct roof penetrations
• Residential roofing repair and retrofit projects
• Light-commercial building installations

Key specifications

• Material: steel
• Pipe diameter accommodation: DN100 to DN125
• Function: roof flashing plate / sealing flange for round pipes
• Application: external roof penetration for chimney, ventilation, exhaust systems
• Suitability: compatible with common roofing materials and roof pitches

How to use

Position the roof flashing plate over the pipe penetration so the adjustable inner collar surrounds the pipe and the base flange rests flush on the roofing surface. Apply an appropriate roofing sealant between the flange and roof material, align the plate to match roof pitch and fastening points, then secure the flange with corrosion-resistant fasteners suitable for the roof type. Ensure the collar is tightened or sealed around the pipe according to the pipe manufacturer’s guidance to achieve a weatherproof joint. Finish by applying additional sealant over fasteners and flange edges where required to maintain continuous waterproofing.

Usage recommendations

Use corrosion-resistant screws and compatible roofing sealants for long-term performance. Inspect the flashing and seals periodically and after severe weather to confirm watertightness. For installations on steep or unconventional roof surfaces, consult a roofing professional to ensure correct flashing placement and secure attachment.
