wet insulation

we have a leak around nail in roof and thus our fiberglass insulation and part of ceiling is very wet in kitchen. Do we need to try and salvage the insulation by fans in attic or replace it? Also what about ceiling to prevent mold?

The insulation will usually dry out once the moisture has been removed.

If you are doing any drywall repairs and have access to the insulation, it is cheap and you might as well replace the damage sections.

If not, it will usually dry to outside (winter months) pretty quickly once you get rid of the moisture source.

If unfaced fiberglass insulation was not contaminated, and there is no mold growth, insulation manufacturers generally state that previously wetted fiberglass insulation can be reused, see for example:

Question: Should I replace wet insulation?

Many people disagree with this advice, but while in my troubled building consultations I'm quick to push for having water damage corrected "properly" even if this is more expensive, I've never been able to find any objective evidence that reuse-in-place of now dry unfaced fiberglass insulation previously wetted by clean water is an inferior practice - all other things being equal - to replacing it.


I'm paid to be suspicious...

Nasty stuff, that: http://www.inspectapedia.com/sickhou...rglassMold.htm The paper on the drywall attic side got wet?

17,000 dryer fires a year, when did you last clean the inside of the dryer near motor or the exhaust ducting?
