Please use our online roof tile calculator to calculate an estimate of how many interlocking roof tiles you need for the whole of a gable to gable roof. The calculator makes four calculations to calculate the amount needed:
Interlocking roof tile calculator
Enter length of the roof (eave length): cm
Enter length of the gable end roof verge: cm
Enter width of the interlocking roof tile: cm
Enter height of the interlocking roof tile: cm
For one side of the roof:
Interlocking roof tiles are needed across the roof length (eave)
Courses of interlocking roof tiles are needed up the roof verge
For the whole roof:
Approximately interlocking roof tiles are needed for this type of roof (including 5% wastage)
Please note that this is an approximate estimation based on a mathematical formula. If you need a more accurate figure we recommend that you carry out your own independent calculation
