Conventional slope roof range between 4 in 12 and 8 in 12. Calculating the surface area of a sloped roof can be time consuming without the right tools. Roughly speaking 1 millimetre of rain over 1 square metre of roof equals 1 litre of water. Anything more than 9 in 12 is considered steep.

You want a roof area calculator that provides accurate estimates to help you order materials such as shingles membrane roofing or ceramic tile. Average would not be a real meaningful number depends too much on the overhang and the shape of the house and roof slope. A low slope roof is anywhere from 2 in 12 to 4 in 12. A 12 in 12 roof can cost up to 50 more than a 4 in 12 roof.

This capacity can be calculated using the following formula. As such while it can be cumbersome measuring the area and pitch of each part of the roof and multiplying by the corresponding correction factor will result in the most accurate estimate of necessary.
