What to look for
- Dark or patchy growth on roof decking or framing.
- Water staining around roof penetrations.
- Damp insulation or signs of a past roof leak.
- Persistent musty odor near attic access.
- Condensation or moisture patterns that recur.
Correct the moisture condition
Cleaning or removing contaminated material without addressing the source can set up the same problem again. Roofing, ventilation, insulation, or other building issues may need attention alongside remediation.
Talk through the scope
Call with any information you have about roof leaks, prior repairs, the location of visible growth, and whether an independent assessment has already been completed.
