vinyl siding under triangular gable vent
I have a two story colonial house with vinyl siding. At the top of the gable there is a triangular gable metal vent. The last piece of vinyl siding which is about 4 foot long attaches to the previous piece of siding and the top slides under the bottom of the gable metal vent. This piece of siding has blown off the wall because I only have 2 nails which attach it to the wall. At this location there is not ample framing to put additional nailing into the siding. Does any one have any suggestions ? Any help will be greatly appreciated. Each sheet of siding are double 4's. The piece in question has had the top nailing holes cut off to fit under the gable vent.
