Lead Roll & Flashing

Lead flashing & roll provides the ultimate weatherproof seal for roof junctions, chimneys, dormers, and abutments where tiles or slates meet vertical surfaces. Trusted by roofing professionals for centuries, lead remains the gold standard for durability and workability, offering protection that lasts decades with minimal maintenance.

Our Lead Roll Flashing Range

We stock quality lead rolls and flashing products to suit every roofing application:

• Milled lead rolls - Code 4 (4lb) - BS EN 12588 certified milled lead in 6m lengths across a comprehensive range of widths (150mm, 225mm, 390mm, 450mm, 600mm) for stepped and cover flashings, valley flashings, and weatherings around roof abutments, chimneys, and dormers.
• Ikoflash self-adhesive flashing roll - a 450mm x 6m self-adhesive bituminous flashing tape for quickly weatherproofing roof junctions, abutments, and penetrations without the need for lead working tools, suitable for both repair and new installation applications.
• Leadax lead-free flashing rolls - an eco-friendly lead replacement made from recycled r-PVB (windscreen safety foil), available in 150mm and 250mm x 6m in grey. 75% lighter than code 5 lead, easy to cut and form, and fully recyclable at end of life while maintaining the look and workability of traditional lead.
• Patination oil - a 1 litre surface treatment applied to newly installed lead to prevent the formation of white carbonate run-off staining on roof tiles and walls below lead flashings, an essential finishing product for all new lead work.

Selecting the correct code weight depends on your specific application. Code 4 handles most domestic flashing work effectively, while exposed locations or commercial projects may demand Code 5. Consider the joint length, expected thermal expansion, and building regulations for your area when specifying lead thickness.
