Your ridge is plenty for 1400 sq ft. and is the perfect shape for a ridge vent. The roofer should cut 3" of roof decking off of each side of the ridge giving you 1/sf of ventilation every 2". Your numbers were incorrect. Anyway you would only be able to span your ridge vent shy of the total legth so approximately 14 lineal feet. If you are still concerned that it is inadequate you could always install the ridge vent and have a power vent installed. A power vent runs off a thermostat connected to some power supply. If your attic space overheats the power vent turns on removing the hot air. An important note is that if you do not have adequate soffit ventilation or if your soffit vents are blocked with items such as birds nests, coverred with drywall or stucco or more commonly insulation (Blown in or batts) it wont matter what kind of ventilation you have on your roof. make sure your roof has adequate ventilation and you will assure your roof provides the usefull life the manufacturers claim . Especially shingle and metal roofs. Overheating of shingles leads to blisterring curling and shortens the lifecycle of any shingle roof and the axpansion and contraction due to heating and cooling of metal roofs will eventually lead to leaks as well
