Best way to fix insulation problem in cathedral ceiling? Please help!
I built my chalet about 8 yrs ago and was up in the attic and noticed black water stains (probably mold).
after many days and night researching what was wrong, i believe my issue is insulation and air leakage.
i have called all the insulation and roofing businesses (not many in this area) and each says its the others issue.
this site has been the most informative, but i cant seem to find any article or videos on how to add or change insulation in a cathedral ceiling after construction has been done.
i had 3 contractors, plumbing, paint/drywall and insulation. i have a 12/12 pitched roof with about 22 ft long cathedral ceiling and a 11ft wide attic about 4 ft high i can get into. 2ft on center 2×12 rafters with 2 lowes bought rafter vents in each space except for ends(could on fit one). i installed a ribbed metal roof on perlins with 30lb felt and 1/2 inch advantech roofing. the insulation is blown in white fiberglass. the walls were packed with it but the cathedral ceiling and attic is so fluffy combined with the ceilling not being sealed i beleive the r value is way to low.
this is where i need your expert advice. the more information i gather for roofing the more confused i get. i do not use it for storage and need help with making it a conditioned space vs non conditioned, vented vs not vented, and whats the best way to achieve this from only the attic or attic and soffit if i had to(would have to take gutters, aluminum trim, and soffit to be able to block it off).
right now i am thinking a few thing, but dont know enough to decide.
1. remove fiberglass, blocke off soffit and ridge vent, dense pack cathedral ceilingwith cellulose and sprayfoam attic. http://www.applegateinsulation.com/Product-Info/Technical-Pages/249234.aspx
2. remove fiberglass seal ceiling and install cellulose in attic and cathedral ceiling, leaving baffles
3. remove fiberglass, seal ceiling, cut strips of some kind of foam boardto slide down rafter bays either with or without rafter baffles.
i am getting a lot of icedaming on roof so i know a big issue is insulation in cathedral ceiling.
and the black stain/mold is lessening since i pulled back insulation and blocke gable vents(since i have full ridge, was told i should block them)
i think my biggest obsticle is trying to fix cathedral ceiling 22ft long from either top or bottom
please help, any and all information would be greatly appreciated!
