Narrative:

Shortly after takeoff we encountered pretty severe wake turbulence. Our aircraft was near max takeoff gross weight. We were cleared for takeoff on runway 15L about 1 minute after a B787. The winds were light out of the south. At about 400 feet the aircraft experienced some light turbulence then began a very fast rolling moment in both directions. The turbulence required me to make very aggressive aileron control inputs in both directions to the stops; as well as associated rudder inputs; although the rudder inputs required were not as aggressive as the rolling momentum was arrested before we departed controlled flight. We were still in the takeoff configuration with the flaps at 5 and gear up; about 190 kts.I did notice on the takeoff that the aircraft had a bit of difficulty becoming unstuck during rotation after the nose rose to the normal take off attitude and required additional pitch inputs. I attributed it at the time to the heavy weight; but think that may have been partly due to wake from the preceding heavy. Not sure. The preceding aircraft was heading down the same route as we were. I offset slightly. There were no injuries or apparent damage; although I later called [maintenance] to advise on making a write up for the aggressive control inputs.
