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.
Home inspector found dark staining on your roof sheathing? Seeing frost on nail tips in winter? Breffni Remediation connects you with licensed and insured independent attic mold removal contractors in Como who clean the decking, correct the ventilation, and stop the condensation causing it.
Most attic growth comes down to three issues: exhaust fans venting into the attic, blocked soffit vents, and air leaks from the house below. Cleaning without fixing them doesn't last.

Here's what separates a real attic fix from a quick spray job.

The quote separates sheathing cleaning, insulation work, and ventilation corrections, so you know what each fix costs before anyone climbs the ladder.
Dry ice and soda blasting lift growth off roof decking without soaking the wood, and HEPA vacuums and air scrubbers handle the dust and spores that come loose.

Attic work combines cleaning overhead with fixing how air moves through the house. These are the core services.

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.
A protective coating can go on once the decking is clean and dry, as an added layer rather than a shortcut.

Here's what some recent callers shared.

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. Frost was building on the nail tips and 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.
Condensation from household moisture, poor ventilation, and air leaks are the main culprits. Roof leaks can add to it.
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.
They shouldn't. Ducting them outside is a simple fix that often solves the problem at its source.
Typically a day or two for cleaning, plus time for ventilation or insulation work.
