The products that Rose Roofing manufacture are covered by ‘BS EN 13707:2004+A2:2009-Flexible sheets for waterproofing – Reinforced bitumen sheets for roof waterproofing – Definitions and characteristics’. The standard harmonises the methods of testing and assessment of the products and provides a consistent manner for the information to be expressed so that meaningful comparisons can be made by the end user. It does not state which products perform best under certain conditions, the decision on whether the product is fit for purpose and intended use still lays with the end user.
The approach the certification takes is twofold, samples of the products are tested for essential requirements as required by the standard (different requirements and test frequencies depend upon the intended use of the product). The test results for the essential characteristics are presented in a Declaration of Performance (DoP) which also shows basic manufacturer information and regulatory compliance of the product / group of products. Please find Rose Roofing’s product DoP’s below.
The certification body also assesses the company’s ability to produce consistent conforming products via its manufacturing procedures and controls and will then issue a FPC Cerfificate (Factory Process Control) which is audited annually.
