Hello All,
My name is Mike. I'm new to the forum and a new home owner. I have a rather odd situation and am in need of a little advice.
Last December we had a record rain event where we live. Due to the excessive runoff, we ended up with 4-5 inches of water under the house, in the crawlspace area. I used a sump pump to pump most of it out, but was unable to get the last inch out, so I let it evaporate out on its own. Long story short...I believe my heating system pumped all that warm moist air into my attic through some 3-in ducts that were left over from a couple old floor furnaces that had been removed. Roof was cold and it all sweated on backs of the roof decking and 1X4's and causes some spotty green mold in certain sections of the roof.
I've been in the attic prior to this event and I know for certain this is new growth and that tere are no leaks in my roof. I plan on having a guy come out soon and wire brush and vacuum the mold spots off. I do have two gable vents and plan on getting some box vents installed to help ventillation and prevent a future event.
What else do you guys recommend I do to prevent this mold from returning? It's a 75 year old house and until now, my ventilation has been sufficient as to not have a mold problem. What other preventative measures should I do to prevent future occurrences? I'm afraid the mold might return later since the spores might be embedded in the wood rafters.
Thanks!3249032491
