We stopped everything until we can find out which way to go. What is the best wayto to this. What other information do you need from me. We do need to add some kind of insulation.
Need help please. Joyce

How large is the cavity between the existing ceiling and the underside of the roof? Are there soffit vents and/or ridge vents?
