Roof sheathing cleaning
Plywood and OSB decking with dark staining is cleaned with dry ice blasting, soda blasting, or HEPA sanding, depending on severity and the contractor's equipment.

Fans and dryer vents that end in the attic get rerouted outside, removing a major moisture source.
Insulation pushed against the eaves can block soffit intake. Baffles restore the air channel, and ridge or roof vents are checked so air flows from low to high.
Removing damaged insulation and sealing the gaps where house air escapes keeps the attic colder and drier.
Once the decking is clean, some contractors apply an antimicrobial or a fungicidal encapsulant coating. It doesn't replace cleaning or ventilation fixes, but it adds a layer of protection.

A few recent attic jobs.

The north slope of our roof deck was covered in dark stains. The contractor found both bathroom fans venting straight into the attic. They dry ice blasted the decking and ran the ducts out through roof caps.
Every winter we'd get water spots on the bedroom ceiling. It turned out to be frost on the nails melting. They cleared the soffits, installed baffles, and sealed around the can lights. No spots this year.
A new roof was already on the schedule, so the contractor cleaned the sheathing first and coordinated with the roofer on adding a ridge vent. Good timing saved us a second trip.
The before-and-after photos kept our sale on track. The buyer's agent had questions and the report answered every one of them.
Usually warm, humid air from the house condensing on cold roof sheathing, made worse by exhaust fans venting into the attic, blocked soffit vents, or poor air sealing. Roof leaks are another cause.
Yes. Ongoing moisture can degrade roof sheathing, rust nails, soak insulation, and show up as ceiling stains or odors. It's also commonly flagged during home sales.
Only if the wood is rotted or delaminating. Cleaning handles most attic mold.
It's a method that fires dry ice pellets at the surface to knock off growth. The dry ice turns into gas, leaving no water or grit behind, which suits attic sheathing well.
No. Bath and kitchen exhaust should be ducted all the way outside through a roof or wall cap. Venting into the attic is one of the most common causes of attic mold.
Most attic jobs take one to three days, depending on attic size, access, the cleaning method, and how many ventilation corrections are needed.
