Lead Free Flashing for Safe Water Harvesting: Addressing Public Concerns with Wakaflex

For centuries, lead flashing has been the go-to solution for creating a watertight seal around chimneys and other roof penetrations. However, if neglected, these lead flashings can wreak havoc on tank water systems. The advent of safer alternatives is now challenging this traditional practice, setting the stage for a paradigm shift in water harvesting safety.

Rainwater is widely regarded as safe to drink, particularly in Australia, where the risk of illness from consumption is generally low, provided the water appears clear, lacks taste or smell, and is harvested via a well-maintained tank and roof catchment system. However, the use of lead flashing in such systems has raised significant public health concerns. These apprehensions stem from the potential of lead to contaminate the water, especially when the lead flashing is not properly maintained. This has thrust the need for safer, non-contaminating components into the spotlight.

Stepping up to address these concerns is Wakaflex with its innovative lead free flashing solution. By providing an alternative to traditional lead flashing, Wakaflex is not merely responding to public health concerns but is also spearheading a transformation towards more sustainable practices in the roofing industry. The introduction of Wakaflex’s lead free flashing underscores the industry’s capacity to innovate and adapt in response to new challenges, setting a promising precedent for the future of sustainable and safe water harvesting. This article will explore how Wakaflex, a lead free flashing solution, addresses these concerns and how it is transforming the roofing industry to be more sustainable.

 

The Issue with Traditional Lead Flashing

In the realm of roofing solutions, lead flashing has traditionally held a prominent position. Known for its malleability and longevity, it has been the preferred material for creating watertight seals around roof penetrations, including chimneys. However, its usage is not without concerns. When lead flashing is ineffectively maintained or incorrectly installed, it can pose significant problems, particularly for those utilizing tank water systems. A lapse in maintenance or improper installation can compromise the integrity of the water system, highlighting the need for caution and precision when dealing with this traditional material.

The consumption of rainwater is widely deemed safe across many regions of Australia, as long as the collection systems are diligently maintained and kept free from contaminants. This practice aligns with the broader push towards environmental sustainability, encouraging households and businesses to tap into nature’s resources responsibly. However, the urban environment, with its myriad pollution sources, presents unique challenges to this endeavor.

Within this urban context, lead has surfaced as a significant concern, primarily implicating poorly maintained roofs and gutter systems. If these systems employ lead flashing and are not adequately cared for, they can become inadvertent sources of lead contamination. This issue underscores the importance of regular maintenance and inspection of these systems to prevent potential health hazards.

Further complicating this scenario are environmental factors, such as the acidity derived from leaf litter. Such factors can exacerbate the risk of lead leaching into roof run-off, amplifying the potential for contamination. This increased risk highlights the complex interplay between human-made structures and the natural environment, emphasizing the need for roofing solutions that are not only durable and effective but also mindful of their environmental impact.

The Law and Public Sentiment

In a world increasingly cognizant of environmental health and safety concerns, laws and public sentiment often converge to drive significant change. This is evident in the roofing industry, where the Building Code of Australia 2006 has unequivocally outlawed the use of lead flashings on any part of a roof designed for potable water collection. The risks associated with lead—a material once ubiquitously used in everything from petrol to paints and plumbing fixtures—have become impossible to ignore. Its potential to significantly contaminate water tanks is a grave concern that underscores the need for safer alternatives.

This legislation and the accompanying shift in public sentiment have sparked a paradigm shift in the construction industry. The prohibition of lead in roofing applications is not merely a regulatory requirement; it is a reflection of a broader societal commitment to reducing environmental hazards and safeguarding public health. The days of widespread lead usage are receding into the past, replaced by an era of increased awareness and accountability. The challenge now lies in identifying and implementing safe, effective alternatives to lead, ensuring that our roofs can withstand the elements without compromising our health or the environment.

The Wakaflex Revolution: Ushering in a New Era of Eco-Friendly Roofing

In an era where sustainability and environmental consciousness take precedence, the introduction of Wakaflex marks a significant stride towards eco-friendly roofing solutions. Developed by Combined Group and manufactured by LaFarge Roofing, Wakaflex is a lead free flashing alternative that champions the cause for non-toxicity in roofing materials. This innovative product not only assuages public concerns over the use of toxic substances but also redefines the standards of eco-friendly roofing, offering a robust solution to the industry’s pressing challenges.

Since January 1, 2007, new houses in southeast Queensland have been required to comply with Part 25 of the Queensland Development Code and the Public Health Act 2005, section 59. These regulations stipulate that lead or any substance containing lead must not form part of a roof system coming into contact with potable water. In response to these stringent mandates, several alternatives to traditional lead roof flashings have emerged, including malleable coated aluminum, malleable zinc, colorbond, and zinc aluminum. Among these, Wakaflex stands out as a premier choice, offering a flexible, adhesive, and most importantly, lead free flashing solution.

Evaluating Risks and Embracing Alternatives

Assessment and mitigation of lead risks are essential practices, especially when there is a conceivable threat to household water purity. Isolation of potential sources of contamination, like old pipes or roofing materials, is critical for maintaining a secure water supply.

The Science and Research

In the ever-evolving world of science and research, new discoveries continually reshape various industries. One such industry that has been profoundly affected is roofing, particularly in relation to the use of lead sheeting. Research led by prestigious organizations like CSIRO (Commonwealth Scientific and Industrial Research Organisation) has illuminated that the primary cause of lead sheet failures often lies not with the material itself but with improper installation practices. This significant finding shifts the focus towards the quality of installation and the essential role that the proportion of flashing plays within a roofing system.

One product that has risen to meet these challenges head-on is Wakaflex, an innovative lead free roof flashing solution. After thorough testing by CSIRO, Wakaflex has been confirmed to comply with the rigorous requirements of AS 2904:1995 ‘Damp Course Flashing’.
