How Permadeck beats the economy’s problems
Welcome to the Seamless Roofing Permadeck® Web Site
We have been installing the finest seamless roofs for more than twenty years.  Our flagship system, Permadeck 20, has been so successful we are proud to describe it as being truly 'once only' - no other flat roof system comes close for performance and durability.  
We are based in Scotland and Chester - probably the wettest area in Europe!
On a cost per year basis Permadeck 20 fibreglass seamless grp roofing is supreme.
For repairing old roofs or building a new one, Permadeck solves problems, forever!
 The ultimate roof for both REFURBISHMENT and NEW
In 1993 Permadeck 20 achieved full British Board of Agrément Certification and it has been refined and developed continuously ever since, making it the most advanced fibreglass GRP roofing system available.
Countless thousands of our roofs are proof of how durable this system is.
