Understand what changes the roof budget
For a 2,000-square-foot roof surface, the Kansas City architectural-asphalt planning example is $8,000 to $12,000. It assumes one shingle layer removed, a new compatible system and haul-away.
Roof area, slope, intersecting rooflines, access and decking repairs change the installed cost. A simpler roof and one with several valleys can need different labor even when the house sizes look alike.
The working calculator keeps its assumptions beside the result and separates measured roof surface from a house footprint.
