Retro Insulation and Roof Venting
We live in Massachusetts and recently replaced our roof with Ecostar plastic shingles and the rep forced the roofer to expand our soffit vents and ridge vents as part of the installation. We had a much delayed energy audit in the midst of the installation and the recommendations have put us in the middle of what seems to be an experts’ dispute. The energy consultant says seal the soffits, spray foam and dense pack the closed rafter area leading from the second floor knee wall to the attic flat. The existing fiberglass in those closed areas does not include baffles at the soffit or proper vents, which seem to be minimum requirements if venting is maintained, and it will be very difficult to install such items (the roofer proposal is to pull the fascia and gutters and shove in the vents).
Any thoughts on an appropriate direction? We’ve even considered venting the south roof, sealing the northWhat is the latest thoughts on the venting issue, or is it still up for debate? Certainly there are those installing shingles over SIP roofing which is the ultimate in unvented roof decking.
Thanks, Stuart Warner
