Roof sheathing cleaning
Growth on the underside of the roof deck is removed by blasting or sanding, followed by HEPA vacuuming of the attic.

Warm, moist air from bathrooms, kitchens, and living spaces leaks into the attic, hits cold roof sheathing, and condenses. Without enough ventilation, that moisture feeds mold on the underside of the roof deck.

Growth on the underside of the roof deck is removed by blasting or sanding, followed by HEPA vacuuming of the attic.
Exhaust fans that dump humid air into the attic are one of the most common causes. Ducts are extended and terminated through a roof or wall cap so moisture leaves the house.
Proper attic airflow needs open intake at the eaves and exhaust at the ridge. Contractors restore that balance.
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.
We were about to replace the roof anyway, 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.
Usually not. Most stained sheathing can be cleaned. Replacement is only needed when the wood is soft, delaminated, or structurally compromised.
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.
Typically a day or two for cleaning, plus time for ventilation or insulation work.
