Oxfordshire’s approved Sika Sarnafil installer

James Dunn Roofing holds the prestigious honour of being Sika Sarnafil's Roof Assured installer for our area, specialising in the refurbishment of flat roofs for the domestic market sector. Sika Sarnafil’s quality roof membrane enhances the lifespan of your flat roof, minimising the chance of cracks, asphalt creep and slumping.


Felt roofs

Felt roofs are one of the best roof coverings available, having been tried and tested over many years. Felt is very tough indeed, and the progress of roofing technology has meant that its fantastic resilience is still improving. Felt roofs are very good at taking the punishment of the elements and are easy to maintain as time goes by. Many of the felt roofs we have installed have lasted over 30 years - and are only in need of replacement now because they're looking a bit worn. With a combination of quality products and professional workmanship, we provide problem-free roofs which will last for decades.

Single ply roofs

Sarnafil waterproofing membranes have been independently assessed by the British Board of Agrément (BBA) to have a life expectancy in excess of 40 years based on actual projects in Switzerland installed during the early 1960's that are still performing today. It is the most specified membrane by architects due to its aesthetics, durability, stringent quality control of both manufacture and installation and is used on many iconic British buildings. These membranes provide a lasting flat roof solution with virtually no maintenance.
