RIS Questions

Our award-winning RIS system has been around for over 20 years. 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 5 degree but ideally 10 degree slope to ensure the drainage system is sufficient in removing any condensation from behind the panels. If less than this, we would advise a fully waterproof membrane would be required beneath the panels. There’s no maximum roof angle as the RIS system can be used vertically as our Facade Integrated System (FIS).

Last night one of GB-Sol’s most ambitious projects was showcased on Channel 4’s Grand Designs.

Creating panels and mountings for such a unique curved roof proved quite a challenge but bespoke architectural solar is our speciality and producing aesthetic designs to compliment a building is what we do best.
