Benefits of Lead flashing The Code 4 Lead Roll by Midland Lead is considerably more flexible and resistant to wear when compared to the older Code 3 option due to its increased gauge making it a suitable choice for almost every type of pitched roofing including vertical cladding, dormer roofs and cheeks, as well as a variety of flashings (such as hip, ridge, chimney, apron, and cover ones). If you’re looking for lead flashing, Code 4 will help waterproof your roof for generations. Lead is malleable but durable, and it typically lasts over 100 years. Lead is a sustainable and environmentally friendly product too. It is 100% recyclable and has a significantly smaller impact on global warming than the production of synthetic materials, not to mention it is also cost-effective, practical and stylish, easy to use and comes in a range of sheet thickness codes to suit your project’s needs.
