Calculating the amount of materials needed for a GRP roof?

From Alice Nash


My husband is wanting to apply your Fibrelast roofing system over our double garage and I need to know how to calculate how much materials we will need to use.


Hi Alice,

To calculate how much GRP roofing materials you’re going to need for the garage, we have created a handy little GRP Roofing Kit Builder over on our fibreglass roofing website. Work out how many square metres your garage roof is and follow the simple steps to select all the materials you’ll need.

If you have any problems contact a member of our support team and we’ll help you with the project.
