CRJ-200 First Officer reported a trailing edge flap fail message on takeoff. After completing the Quick Reference Handbook procedures; the flight crew elected to continue to the destination airport.

Narrative

During initial climb out of ZZZ1; Captain called for climb sequence at 7;400 ft. as suggested by company charts. I retracted flaps 8 to up and subsequently received a flap fail caution message. The flaps failed at 8 degrees. We continued our climb due to terrain and respected flap speed limits. The Captain transferred the controls to me and began the flaps fail 8 Quick Reference Handbook procedure. We elected to continue to our destination of ZZZ2 while the Captain read through the Quick Reference Handbook. This decision also brought us out of hazardous terrain landscapes to flat lands.We cruised at 13;000 ft. to avoid terrain and stay below our flap ceiling (minimum vectoring altitude was 11;000 ft. around ZZZ1). Half way to ZZZ2 the Captain finished the initial Quick Reference Handbook procedures which read 'land at nearest suitable airport'. We decided that ZZZ2 was our nearest suitable airport due to longer runways; increased ARFF level; and favorable weather. We asked for a holding pattern outside of ZZZ2 visual approach area in order to burn fuel for a more favorable landing weight. We were concerned landing too heavy would have us land above our nose wheel tire speed according to the Quick Reference Handbook. Purposely burning enough fuel that we called 'minimum fuel' to ATC we began the FMS visual in ZZZ2. Other than higher pitch attitudes and a longer flare the landing was uneventful. After landing we had 1;450 pounds of fuel. We were de-iced prior to takeoff. Delayed flap retraction due to the ZZZ1 Jeppesen all engines running departure chart recommending flap retraction at 7;400 ft. It would be nice to have more clear guidance in the Quick Reference Handbook for the Flaps Fail message on maximum landing weight. On initially reading the Quick Reference Handbook we assumed we would be landing overweight at flaps 8 and potentially exceed our tire speed limit. After some study we realized the Quick Reference Handbook assumed we were landing at 10;000 ft. rather than sea level in ZZZ2. If we would have discovered this sooner we could have landed with an extra 1;000 pounds of fuel and not have declared minimum fuel.
