About Roof Assured  

Roof Assured is part of the Sika group of companies, which operates the leading brand of single-ply roofing: Sarnafil.
Sarnafil launched its first waterproofing membrane in Switzerland over 40 years ago and many early Sarnafil roofs installed in the 1960s are still performing superbly today.

Here in Great Britain, Sarnafil roofing has been specified for many prestigious projects such as Arsenal FC’s new Emirates Stadium; the Bluewater Retail Centre, Kent; Heathrow, Gatwick, Stansted and Bristol Airport passenger terminals; and the new St. Pancras Railway Station.
World class roofing for the home owner
Roof Assured takes the wealth of knowledge and experience gained within the commercial sector to provide home owners with a superb long term, Sarnafil flat roof solution. You’ll see our roofs on all kinds of domestic buildings, from simple garages to superb, architect-designed houses. Sarnafil roofs have even appeared on television, in programmes including ‘Grand Designs’ and ‘Property Ladder’.
Installed by experts
Even the best product can be compromised by poor installation, so Sarnafil roofing membranes are only installed by Registered Installers who have been trained by the manufacturer. Also the company’s Applications Department provides advice and practical on-site assistance through its team of experienced Field Technicians who support the Roof Assured Registered Installers.
