RIS Questions

Our award-winning RIS system has been around for over 20 years and is the foundation of our Infinity and Integrated roof integrated systems. If you have a question, you may find the answer here.

Q. Is my roof suitable for RIS?
A.

Most roofs are suitable for our roof integrated system. Please get in touch with your architect’s drawings and we’ll be happy to confirm and offer advice if required.

Q. What information do you need to give me a quotation?
A.

For a new build, please send us an email containing your architect’s drawings (all elevations and a site plan if possible). If it’s an existing building, please provide the roof dimensions and details of any obstructions such as roof lights or vents. If neither of these are possible, please provide the address and we may be able to give a very rough guideline quotation.

Q. How much is the RIS per square metre?
A.

The design of the system will depend on the roof shape and dimensions so there isn’t a fixed cost per square metre. Please contact us with details of our project for a personal budgetary quotation.

Q. Is there a minimum or maximum roof angle for the RIS?
A.

The roof needs to have at least a 15 degree slope to ensure the drainage system is sufficient in removing any condensation from behind the panels. If less than this, contact us and we can discuss the options. There’s no maximum roof angle as the RIS system can be used vertically as our Facade Integrated System (FIS).

Q. Is the Roof Integrated System an accredited product with the Microgeneration Certification Scheme (MCS)?
A.

Yes, contact us to discuss why this may be important for your project.

 

Q. How heavy is the system?
A.

20kg per square metre, so much lighter than most clay tiles & slates

PV Slate chosen for Barnes Methodist Church

We are now fitting x338 of our largest solar PV Slates to Barnes Methodist Church in west London, discretely generating 12kW of solar power on this wonderful listed building. 

The new roof can be seen from the B349 Station Road side of the church.  The trustees of the church decided to use GB-Sol PV Slates after Richmond Council determined that putting conventional solar panels over the roof of this historic building was not appropriate
