The Sarnafil Roofing Membrane

***The Sarnafil roofing membrane is dimensionally stable and impervious to extremes of temperature***. It's also UV resistant, so there's no need for a layer of chippings to collect moss and soil or to cause puncture problems some time in the future. We finish the edges and joins with a weld technology that's even stronger than the membrane itself, and pipes, skylights and other intrusions are positively sealed using Sarnafil-approved and patented tapes and sealants.
