This past summer we had a new roof (architectural shingles) and vinyl siding installed on our 1972 colonial. We live in zone 6, so snow is a part of life. The previous siding was concrete-fiber shingle and the insulation in the walls was original. All of the windows have been replaced within the past six years and attic insulation has been upgraded as well. The attic originally had gable vents at either end with soffit venting under a 10 x20' main entrance overhang. There is an unvented six inch eave overhang in the front but none in the back; the siding abutts a fasciaboard which borders the roof.
The roofing contractors installed ridge venting the entire run of the roof (approx 50') but closed off the gable vents. The siding was installed with 1" foam but no vapor barrier. This winter we have had two large snow events followed by freezing temps. We have had an ice dam form and water infiltration above the same bedroom window each time. This beroom has a sloped ceiling due to the roof design.
My question is whether to remove the gutter and vent the fascia in the back of the house? Or, don't worry about venting the base of the roof and re-install the gable vents at each end of the house?
Thank you in advance.
