Roofing Standards and Regulations

No BMI product gets on the roof without passing a comprehensive programme of stringent tests in our world-leading testing, research and validation centre. Our roofing and waterproofing systems are specifically designed in the UK to meet the demand of our weather conditions, climate and industry standards.

Testing & Validation

Validation tests

All elements of our roof systems have to pass the tough validation tests. This is the BMI way to ensure that your complete roof resists all weather conditions as a system.

The best at testing

Our own requirements for performance and quality always exceed the national specifications. We test and validate all products much higher and far beyond national standards. Only when the complete BMI roof system can withstand all our tests will it be validated to cover your roof. 


Ongoing development

The testing does not end with the successful development of a product. We take our responsibility seriously in development and also in ongoing production. Even if the products have spent decades on rooftops all over the world in all climates, we get samples to our testing facilities to analyse how they’ve fared and how they could withstand the weather even better.
