I just stumbled on this site and could use some help from the experts!
I live in NH and have had ice dams every winter. I finally inspected the attic and discovered all of the soffit vents were blocked with insulation. For several weeks I cleared them and installed the Corning Raft-R panels to create air flow from the soffits to the ridge vent.
We just had our first snow fall and I have two foot icicles again! :roll:
I have continuous soffit vents and I thought maybe they were dirty. I pulled a section of soffit out to see what it looked like above the soffit vent and was surprised to see that the section where air enters my attic is less than 1/2" thick. Surely, this is my problem.
So I have a ridge vent but totally inadequate air intake through the soffits.
I assumed I would install rectangular gable vents (if that’s what they’re called) in each end of the house but one side is dangerous to get to from the outside especially in the winter.
Can I install one large vent on the safe end (not windward) of the house in hopes that will be the air intake and it will vent out through the ridge? If so, should I have one large or several smaller vents on that side? Should I get close to the top or lower? Sorry for all the questions but I’m not sure where to go from here but I need this solved quickly. Yes, I could hire a pro but I tend to figure things out and do them myself. TIA!!! 8)
