Attic Smells You Should Never Ignore
Attics can experience temperature extremes and they aren’t going to smell exactly the same as the rest of the house. But some attic smells can indicate a pest problem, a mold problem, or some other issue.
Have you ever paused in your attic to wonder what that funky smell is? Whether you’ve run up to the attic to stash a box of summer clothes or whether you’re inspecting your roof’s ventilation system, you need to pay attention to what your nose is telling you.
If you smell something suspicious or something out of the ordinary, you may have a new roof or attic problem that requires your attention.
Damp or Mildewy Smell
If the air smells damp but you don’t see any mold or standing water, that doesn’t mean everything’s fine.

The moisture source could be under the insulation, down inside the walls, all the way down in your basement, or even in your HVAC ducts, or simply tucked away in a corner where the roof has started to leak unobtrusively.
Unfortunately, once you have an attic mold problem, it’s likely to spread unless you get to the bottom of it and eradicate it, then remove the source of moisture.
