Attic Mold from Roof Leaks and Ventilation Failures
Ice dams, missing shingles, and inadequate attic ventilation create perfect conditions for mold on roof sheathing, rafters, and insulation. We fix the moisture source and treat contaminated wood safely.
Ice Dam Forces Water Under Shingles Creating Attic Mold
Recurring winter ice dams allowed snowmelt to infiltrate under roof edge, soaking attic insulation and causing extensive black mold growth on plywood sheathing covering 150+ sq ft. Multiple rafters showed active growth requiring immediate remediation before rot developed.
Our Solutions:
- Coordinate roofer to repair damaged shingles and flashing
- Remove contaminated insulation from affected areas
- HEPA sand blast or dry ice blast removes mold from sheathing
- Apply EPA-approved wood fungicide to all treated surfaces
Poor Attic Ventilation Causes Frost and Mold Growth
Inadequate soffit and ridge venting trapped warm moist air in attic during winter. Condensation formed frost on roof deck that melted in spring, creating widespread mold on sheathing, rafters, and trusses throughout 800 sq ft attic space.
Our Solutions:
- Install proper ridge vent and clear soffit vents for airflow
- Add baffles between rafters to maintain ventilation pathway
- Remediate mold on all affected wood surfaces
- Upgrade attic insulation with proper air sealing
Bathroom Exhaust Fan Venting Into Attic Grows Mold
Bathroom exhaust fan improperly terminated in attic space instead of venting outside. Years of shower steam moisture condensed on sheathing and rafters directly above bathroom, creating 40 sq ft mold zone with visible discoloration and musty odor detectable in bathroom.
Our Solutions:
- Reroute exhaust fan duct to proper exterior termination
- Insulate new duct run to prevent condensation inside duct
- Remove mold from affected sheathing and framing
- Seal ceiling penetration to prevent future moisture migration

Step 1Assessment & Scope
Identify sources and affected areas
- Visual inspection with moisture mapping and thermal imaging
- Define remediation scope by area and material type
- Plan containment zones and negative air setup
- Document conditions for insurance and reporting
- Safety review and PPE requirements
🚧
Step 2Containment & Negative Air
Prevent cross-contamination
- Install plastic containment with zipper doors
- Negative air machines with HEPA filtration
- Pressure monitoring to maintain safe airflow
- Isolate HVAC and protect clean areas
- Establish decon area for crew entry/exit
🧼
Step 3Removal & Cleaning
Remove contaminated materials safely
- Source removal of porous materials (drywall, insulation, carpet)
- HEPA vacuuming and wire-brush cleaning of framing
- Application of antimicrobial/fungicide per label
- Bagging and proper disposal as per local codes
- Content protection and limited pack-out as needed
🌪️
Step 4Air Filtration & Drying
Improve air and reduce humidity
- HEPA air scrubbers run continuously during work
- Dehumidification to reach target RH levels

Frequently Asked Questions
Everything you need to know
Why is there mold in my attic?
Attic mold is almost always caused by moisture: roof leaks (current or past), poor ventilation trapping humidity, bathroom exhaust fans venting into the attic, or ice dams causing snowmelt intrusion. Inadequate insulation and air sealing can also allow warm, moist air to rise from living spaces and condense on cold attic surfaces. We identify all moisture sources during inspection and recommend permanent fixes.
Can attic mold affect my indoor air quality?
Yes, especially if you have ductwork, air handlers, or recessed lights in the attic. Mold spores can infiltrate living spaces through these penetrations, causing musty odors and respiratory irritation. Even sealed attics allow some air exchange. Removing attic mold and fixing moisture sources improves overall home air quality and prevents health concerns.
Do I need to replace my attic insulation after mold removal?
If insulation is contaminated by mold, it must be removed per IICRC S520—it cannot be effectively cleaned. However, if mold is limited to roof sheathing and framing, insulation may be salvageable with HEPA vacuuming and antimicrobial treatment. We assess contamination extent and provide honest recommendations. Replacing insulation also offers an opportunity to upgrade R-value and improve energy efficiency.
How do you treat mold on attic wood?
Mold on wood sheathing and framing is treated with wire brushing and HEPA vacuuming to remove surface growth, followed by EPA-registered fungicide application to kill remaining mold and prevent regrowth. Severely damaged wood (soft, crumbling) may need replacement for structural integrity. After treatment, we address ventilation and leak issues to prevent recurrence.
How much does attic mold removal cost?
Attic mold remediation costs vary based on extent of contamination and attic size: small areas (less than 100 sq ft) typically run $2,000-$4,000, moderate contamination (100-300 sq ft) costs $4,000-$8,000, and extensive growth throughout large attics can reach $10,000-$15,000. Price includes containment, mold removal, antimicrobial treatment, insulation removal/replacement if needed, and proper ventilation improvements. We provide free assessments and detailed quotes.
Will homeowners insurance cover attic mold removal?
Coverage depends on the cause. If mold resulted from a sudden covered event (burst pipe, storm damage, ice dam from covered roof leak), insurance typically covers remediation. However, mold from long-term neglect, poor maintenance, or gradual roof deterioration is usually excluded. We document all damage thoroughly, provide detailed estimates, and work with your adjuster to maximize coverage when applicable.
