SDH Advanced Developments Ltd is a well established family run business specialising in flat roofing. Our aim is to minimise costs whilst maintaining the highest levels of quality. We are proud to share with each client our wealth of knowledge and experience enabling us to offer innovating ideas, design input and time. Roofs not only need to perform their weatherproofing function, but they need to look good as well, the Sarnafil membranes we provide come in a range of colours with matching edge trims and aesthetic profiles available to imitate traditional roofing systems, such as lead or other metals. The membrane itself is extremely versatile making it ideal for a wide range of roofing projects. Our systems have been independently certified to have a life expectancy in excess of 40 years. The products we offer include, but are not limited to Green roofing Systems. These systems consist of lightweight, naturalistic planting requiring minimal maintenance with a huge range of benefits including suitability for use on roof slopes. All installations come with a comprehensive 15/25 year guarantee depending on the thickness of the membrane. For further information, samples or literature please contact us on the details below.
