Better reception through an attic vent or through the roof?

(I searched the forum but couldn't find this specifically addressed.)
I have a question about the best direction to orient an AntennaCraft C290 antenna in my attic. (I don't want to put it on my roof- not yet, anyway.) I live 15 miles north of WashDC and 25 miles W-SW of Baltimore. From the map shows major signals from DC: 15 miles at 185 deg; and from Baltimore: 25 miles at 62 deg. The report is here. The house is wood frame with vinyl siding. The roof is a typical low-pitch, open gable roof, plywood w asphalt shingles. The ridge runs almost east/west (95deg/275deg), so the flat roof sections face almost north/south (5deg/185deg). At the eastern end of my attic (on the east-facing gable and centered under the ridge) is a small, rectangular, louvered plastic vent, about 15"W x 25"T, with a metal screen over it, but otherwise open. My question is- how should I orient my antenna for best reception of the WashDC signals from the south? Will signals from DC be stronger coming through the small, east-facing vent or coming directly through the south-facing, pitched, plywood, asphalt-shingled roof? I'm sure pointing the antenna toward the vent will let it receive the Baltimore signals better, just not sure about the best orientation to get the DC signals. All thoughts appreciated.
