Steps to reduce mold prior to installation

Return to Installation

Return to Forum

Twenty years ago, we redid the house we live in. In the living room we have a cathedral ceiling. We foolishly did not remove the sheetrock and add baffles. We have no idea if there is insulation or what value might be if it is there. We put up popcorn to hide cracked paint. Popcorn cracked and peeled. I scraped popcorn and have started putting up boards over the sheetrock and have discovered some mildewed spots. We did install ridge and soffit ventilation. We were thinking to put a metal roof on but now I am concerned it will only increase the condensation. Would baffles and an underlayment help or do I need to rip out the ceiling? We do have a moisture problem from an old chimney. Any suggestions would be greatly appreciated.

Usually, metal roofing doe snot impact things as far as condensation but you have a situation where the lower temperature of a metal roof could increase the risk of condensation. Preferably, I'd like to see (from the inside out): oil base paint, drywall, vapor barrier (such as polyethylene), insulation, ventilation, roof deck, underlayment, metal roof. I hope this helps. Please contact me anytime.
