Flat roofs are often praised for their modern appearance and space-saving benefits; however, they also present unique challenges, particularly the issue of water ponding. Ponding, or the accumulation of standing water, can compromise the longevity and functionality of a flat roof, leading to water damage, leaks, and even structural issues if left unaddressed. One of the most effective solutions to this problem is the application of liquid roof covering. In this article, we explore how liquid roof coverings work to prevent ponding, and why it’s an ideal choice for flat roofs in Soham, Cambridgeshire.
Understanding Ponding on Flat Roofs
While flat roofs are designed with a slight gradient to allow water runoff, ponding can still occur due to structural shifts, poor drainage, or heavy rainfall. Even minimal water accumulation can be problematic, as it adds extra weight to the roof and can weaken its structural integrity over time. Repeated cycles of ponding and drying can cause material degradation, cracks, and ultimately water infiltration, leading to potential damage to the interior of the building.
What is Liquid Roof Covering?
Liquid roof covering is a highly flexible, waterproof membrane applied in liquid form across the surface of a flat roof. Once applied, it cures to form a seamless, protective layer that not only prevents water infiltration but also helps redirect water flow to drainage points. The material’s adaptability and durability make it an ideal solution for flat roofs, where traditional roofing materials may struggle with water resistance and flexibility.
How Liquid Roof Covering Prevents Ponding
1. Enhanced Water Flow and Drainage
Liquid roof covering creates a seamless, even surface across the entire roof, eliminating gaps, seams, or overlaps where water might accumulate. By forming a continuous layer, it enhances the roof’s natural slope, aiding in the redirection of water to designated drainage points and thereby reducing areas where water could pool.
2. Flexibility to Adapt to Roof Settling
Over time, roofs can experience slight shifts or settling, which may lead to low spots where water can pond. Liquid roof coverings are designed to remain flexible after application, meaning they can accommodate these minor shifts without cracking or peeling. This flexibility ensures that the protective membrane continues to function effectively, even as the roof settles or expands due to temperature changes.
3. High Resistance to UV Rays and Temperature Fluctuations
Exposure to ultraviolet (UV) rays and fluctuating temperatures can weaken some roofing materials, causing them to become brittle and susceptible to damage. Liquid roof coverings are formulated to withstand UV exposure and extreme temperatures, maintaining their durability over time. This resistance means the roof can continue to repel water effectively, reducing the risk of ponding as the material maintains its integrity.
4. Self-Levelling Properties for a Smooth Surface
Many liquid roof coverings possess self-levelling properties, ensuring that once applied, the covering naturally spreads out to create an even layer across the entire roof. This self-levelling ability minimises any existing dips or depressions in the roof, addressing small low spots where ponding could occur. By smoothing out these areas, the roof covering significantly reduces ponding risks.
5. Fast and Seamless Application Process
Liquid roof covering offers an efficient application process, reducing installation time and minimising disruptions. Applied in liquid form, the covering fills in every crack, seam, and corner of the roof surface, creating a highly uniform membrane. Without seams or joints, there’s less chance for water to seep beneath the surface, ensuring long-lasting protection against moisture penetration.
Additional Benefits of Liquid Roof Covering for Flat Roofs
Beyond its ponding prevention capabilities, liquid roof covering brings several other benefits that make it a practical investment for flat roofs:
- Extended Roof Lifespan: By preventing water damage and UV deterioration, liquid roof coverings help extend the lifespan of the roof, reducing the frequency and cost of repairs or replacement.
- Eco-Friendly Solutions: Many liquid roof coatings are low in VOCs (volatile organic compounds) and environmentally friendly, making them a responsible choice for property owners looking to minimise their environmental impact.
- Energy Efficiency: Some liquid coverings have reflective properties, which can help reduce the roof’s heat absorption. By reflecting heat away, these coatings can help maintain a cooler indoor environment and potentially lower cooling costs in warmer months.
Conclusion
In areas like Soham, where variable weather conditions can lead to water accumulation on flat roofs, liquid roof covering offers an effective, durable solution to combat ponding. Its seamless application, flexibility, and resistance to weather conditions make it ideal for preventing the costly damage that ponding water can cause. With the added benefits of longevity and energy efficiency, liquid roof covering is a valuable investment for maintaining a flat roof’s integrity and performance.
