When you’ve been in the roofing game as long as I have, you learn to spot true innovation. And Sarnafil? They’re the real deal.
The Birth of a Roofing Revolution
Founded in 1962, Sarnafil emerged in Switzerland as a specialist in high-performance roofing membranes. Decades later, in 2005, Sarnafil was acquired by Sika, a global leader in construction chemicals founded in 1910 by Kaspar Winkler. This powerful union combined Sarnafil’s membrane expertise with Sika’s legacy of innovation and global reach.

From Swiss Precision to Global Leadership
What began as a local Swiss operation quickly grew into a global powerhouse. By focusing on precision engineering, long-term durability, and forward-thinking design, Sarnafil evolved from a small manufacturer into a benchmark in roofing technology worldwide.
The Technological Breakthrough
The G 410-60 EnergySmart membrane became their flagship product, and for good reason. But if you want to know why I changed my mind about single-ply systems after years of hating them, read my full breakdown here: Why I Went from Hating Single-Ply to Swearing by Sarnafil.
-
Exceptional Durability: 60 mils thick with fibreglass reinforcement
-
Reflectivity: Highly reflective, helping reduce heat absorption
-
Longevity: Independently certified by the BBA to last over 40 years
Sustainability: Long Before It Was Trendy
While many companies are only recently embracing sustainability, Sarnafil has been doing it for years. Since 2008, their recycling program has diverted over 100 million pounds of PVC from landfills.
A Closed-Loop Approach
Their Old Roof Take Back Program allows building owners to recycle their old PVC roofs at no additional cost. This isn’t just a marketing tool—it’s a genuine commitment to environmental stewardship.
Technical Innovations That Set Them Apart
Hot-air welded seams, factory-applied coatings, and membranes that handle extreme conditions all make Sarnafil stand out. I’ve shared real project stories—both disasters and successes—that prove how much these innovations matter in practice. See the full article here: Why I Went from Hating Single-Ply to Swearing by Sarnafil.
-
Hot-air welded seams for superior waterproofing
-
Factory-applied lacquer coatings
-
Membranes that perform reliably in extreme temperatures
-
Excellent resistance to fire and chemicals
Global Recognition and Proven Performance
The British Board of Agrément (BBA) has rigorously assessed Sarnafil membranes and confirmed their exceptional quality. When installed by approved contractors, these membranes have a certified life expectancy of over 40 years, a rare feat in the industry.
Energy Efficiency: A Real-World Benefit
While many manufacturers make bold energy-saving claims, Sarnafil takes a measured approach. Their white reflective membranes are designed to reduce heat absorption, contributing to improved energy efficiency. While specific figures like a 14% reduction in peak demand or 11% drop in daily usage aren’t officially confirmed by public sources, there is general industry support for the cooling benefits of reflective roofing systems.
Beyond the Membrane: A Commitment to Quality
Sarnafil’s success isn’t just about products, it’s about a relentless commitment to quality, demonstrated through:
-
Strict manufacturing processes
-
ISO 14001 environmental management certification
-
Comprehensive warranty options
-
Ongoing research and innovation
Why Professionals Trust Sarnafil
Having worked across the UK, Canada, and the US, I’ve seen why contractors stick with Sarnafil. My own experience took me from near business-ruin to swearing by it for complex projects like roof gardens. The full story is here: Why I Went from Hating Single-Ply to Swearing by Sarnafil.

The Manufacturing Advantage
Made to Swiss engineering standards, Sarnafil membranes are a hallmark of quality. While PVC membranes generally use less petroleum-based material than many other roofing systems, the specific claim that Sarnafil membranes are made from 53% salt could not be independently confirmed.
A Legacy of Innovation
From their beginnings in 1962 to becoming a leader in global roofing solutions, Sarnafil has never stopped innovating. They’ve helped redefine what flat roofing can be: a durable, efficient, and environmentally responsible system.
Looking Forward
As roofing technology evolves, Sarnafil continues to push boundaries. Their dedication to sustainability, high performance, and innovation continues to raise the industry standard.
For professionals and building owners looking for reliable, long-lasting solutions, Sarnafil isn’t just an option—it’s the benchmark.
