What happened in Green Bay
CCS handled this attic mold job in Green Bay. The project was opened on March 19, 2024, and all 36 photos were taken that day.
The attic is framed with trusses under an OSB roof deck, with pink fiberglass insulation on the floor and a metal flue pipe running up through it. Across much of the roof, the OSB is covered in black spotting, heaviest in the middle of the slopes and near the ridge, and some bays have darker streaks where moisture ran down the boards.
Several photos show sections of the attic where the trusses and the roof deck have been coated white, next to sections that are still bare and spotted. A white encapsulant goes on after the wood is cleaned and treated. It seals the surface and makes any new staining easy to see later. Black spotting spread evenly across an attic deck is a classic sign of condensation from household air rather than a roof leak.
