Can a roof calculator compute complex roof structures?

This calculator can estimate easy roof structures. But if you want to calculate complex roof shapes, this might be a challenge but still can be useful; we have this area calculator that helps you first to know the area of your roof based on which the other calculation on price can be made. 

In simple terms of complex structure, this does not show you an accurate area but can give you an approximate area while estimating the roofing area for residential purposes. 

It is preferable to speak with a local contractor and request information on labor and material costs per square meter or square foot of roof space. Remember that the cost of removing all layers and disposing of them should be included in this unit pricing, along with any additional components like fasteners.

Right before beginning the work, it is essential to check with other contractors if your contractor's price proposal deviates from these figures. Suppose you cannot reach any contractors; double the cost of materials by 2.5 by finding the closest building supply store, for instance. Using the assumption that labor makes up 60% of the cost and materials make up 40%, you may calculate an approximate price that includes labor.
