A Non-Lead Waterproof Flashing Solution
When it comes to weatherproofing structures, versatility and durability are key. Traditionally, lead flashing has been the material of choice for various roofing applications. However, Ubiflex Standard—a non-lead waterproof flashing material—offers a modern solution with a host of advantages. From easier installation to reduced theft risks, Ubiflex Standard is becoming the go-to choice for roofers and builders alike. But where exactly can you use this innovative product?
1. Fixing Into a Wall or Chimney
One of the most common uses of flashing is sealing the junctions between a roof and a vertical surface, like a wall or chimney. Ubiflex Standard performs exceptionally well in these situations, ensuring a watertight seal that protects against leaks. With its flexibility and lightweight nature, Ubiflex can be easily molded to conform to awkward angles or curves around chimneys and walls, making installation quicker and more efficient compared to traditional lead.
2. Without a Damp Proof Course (DPC)
Lead flashing often requires the installation of a damp proof course (DPC) to prevent moisture from penetrating the structure. Ubiflex Standard, however, doesn’t require a DPC to provide superior protection against water ingress. Its waterproof properties make it ideal for scenarios where you want to avoid the extra step and material of adding a DPC. It’s a simple, efficient, and reliable solution that maintains a high level of waterproofing.
3. Larger Joints
In cases where there are larger gaps between surfaces or irregular joints, Ubiflex Standard excels. Thanks to its flexibility and malleability, it can easily bridge larger gaps without compromising the seal. This is especially beneficial in older buildings where walls and roofs may not align perfectly. Ubiflex fills the gap and ensures water stays out, offering a long-lasting and durable solution for larger, uneven joints.
4. Flashing to a Flat Roof Upstand
Ubiflex Standard is perfect for creating a waterproof barrier where a flat roof meets a vertical upstand, such as parapet walls or roof terraces. Its lightweight design and ease of cutting allow it to be precisely tailored to these joints, forming a secure and weatherproof seal. Moreover, Ubiflex is 50% quicker to install than lead, allowing roofers to complete projects more efficiently without sacrificing quality.
5. Flashing to a Wall or Chimney
Whether it’s a brick, stone, or concrete wall, Ubiflex Standard offers a reliable flashing solution that’s easier to install than lead and provides long-lasting protection. It can be securely fixed into mortar joints or surface-fixed to ensure watertightness. Around chimneys, Ubiflex can adapt to various profiles and shapes, creating a durable weatherproof seal while eliminating the theft risk associated with traditional lead flashing.
6. Flashing to Vertical Tile and Slate Hanging
In areas where the roof tiles or slates are installed vertically, such as gable ends or dormer windows, Ubiflex Standard offers a seamless flashing solution. Its flexibility allows it to easily conform to the contours of tiles and slates, ensuring a tight seal that prevents water ingress. Ubiflex is also less likely to crack or tear over time, ensuring long-term durability and performance in vertical tile and slate hanging applications.
7. Flashing to Canopies, Hoods, and Carports
Ubiflex Standard is ideal for canopies, hoods, and carports where a waterproof junction is required between the roof structure and any adjoining walls. Its light weight makes it easy to install without the risk of damaging the structure, and the material’s longevity ensures it will withstand exposure to the elements for years to come. Whether it’s a residential carport or a commercial canopy, Ubiflex guarantees watertight protection.
8. Pitched Valley Lining
In pitched roof valleys, water drainage is critical, and Ubiflex Standard offers an excellent solution for lining valleys where two roof slopes meet. Due to its flexibility and ease of shaping, it can create a perfectly fitted valley lining that directs water away efficiently, preventing leaks and pooling. Its lighter weight also reduces the overall strain on the roof structure, making it ideal for pitched valley applications.
