If you have recently purchased a property with a flat roof then you should be able to find out how much of it is flat by referring to the home buyer’s survey for specific measurements.

Alternatively, you can have a survey carried out by a qualified builder, roofer or surveyor and ask them to calculate the percentage of the roof that is flat. It’s important to have this information to hand when taking out a quote so as to be able to secure accurate cover for your property. To get a quote, you need to know which bracket your flat roof fits in to: 0-33%, 34-50%, 51-75% or 76-100%.
