The most common reason brake rotors warp is due to improper installation. Lug nuts MUST be torqued correctly. Do not just zing them on with an impact, do not let a shop do that either. Torque them to spec by hand, with a torque wrench. The next best way is to use an impact wrench, but only with a torque stick attatched. And to answer the question better, heat is what enables a rotor to warp, but all rotors get hot during normal operation. The reason they DO warp is the uneven pressure applied to them by the lug nuts.

Seeing how everyone mentioned the most common things like mountain driving, drivers use of brakes, sticking calipers and all that stuff...
There is one more thing to consider while we are on the subject;
Those brake rotors that are solid with no webbing and internal air pockets.. are notorious for overheating and warping.. just drive down a steep mountain one time riding the brakes is enough to warp the whole lot of them.
I've seen them on Subaru and the rear of Buick regals.
That would work for driving in the flatlands, but for driving over 2500 feet above sea level forget about it.
Some brake pads that are designed for long life will destroy rotors also.

Excessive heat. That can be caused by 3 things:
1. Stuck piston(s) in caliper
2. Riding the brakes (left foot brakers often ride the brakes)
3. Excessive use of the brakes -- driving habits, mountain driving or towing heavy loads

Heating the brake rotors up.

your rotors are too thin and need to be replaced. the heat from constant braking is warping them out of shape.

excessive heat I had a 94 t bird that never went over 13000 miles before needing new rotors also problem with transmission not gearing down correctly

overheating ; when the rotors get too thin through wear and resurfacing they tend to overheat which in turn causes them to warp

Heat usually. Happens mostly when you drive with your foot hovering over the brake pedal...

Yes overheating them is one way but the other most common thing is uneven torquing of the lug nuts.

Heat. Ride your brakes - and this is what you get!
