Roof leak - drywall repair question
I had a leak in my roof that has caused a significant amount of water to come down through an outside wall and soak my carpet. Roof is fixed, and the carpet was pulled up and dried out. My question is this:
Should I remove the section of drywall and insulation and replace, or should I just let it dry out on it's own. The drywall is solid (although a bit soft in one or two small places), and there are a couple of nail pops. The insullation is blown-in cellulose (packed very tightly).
My main worry is the cellulose holding onto the water, and mold growing in the wall. I've had a couple of different opinions, but all from non-professionals.
Can someone with experience weigh in? Obviously, I'd like to leave it - the repair job will be time consuming, costly, and messy. On the other hand, I'd really don't want a wall full of mold. Please help. Thank you in advance for any advice you can offer.
