Tried spray foam in my attic after that leak in Portland last spring - now I'm split on it
My mom's house in Portland had a roof leak last April, and I helped her rip out all the old fiberglass batts. I pushed for closed-cell spray foam, sealed everything tight. Fast forward to August, and her AC has to run way harder, and I'm worried about moisture trapping. Guys on this forum swear by it for air sealing, but my HVAC buddy says it's a nightmare if you ever need to rewire. So what's the real deal - is spray foam worth the risk of high bills and hidden rot, or should I stick to batting?
