Narrative:

When configuring for landing while on expressway visual approach to runway 31 at lga; the flaps remained at 20 when flap handle was selected to 25; resulting in the 'trailing edge flaps disagree' EICAS message. We performed a go around; coordinated with ATC and completed the associated QRH checklist. We found the checklist confusing in regards to the required configuration for landing. Based upon [minimal] fuel available for diversion and considering the runway length at lga; a decision was made to lower flaps electically to 30 and land lga. The landing was uneventful. Upon debrief; we agreed that it may have been prudent to consider [the possible performance reduction due to] slow electrical flap retraction speed in the event of the need to perform an engine out missed approach.

Title: The flight crew of an unknown Boeing aircraft performed a go around at LGA when they received a TE FLAP DISAGREE EICAS message. They performed the associated checklist and opted to land with flaps extended to 30 degrees using the alternate electrical flap extension procedure.
