selling our home in allentown pa (lehigh valley). buyer's inspector went into the attic and found black mold across the north-facing plywood roof decking. inspector noted that our blown-in fiberglass insulation was completely blocking the soffit vents. closing is in 6 days and the buyer's mortgage lender requires an official clearance certificate. how do we remediate the attic plywood and restore ventilation baffles without replacing the roof deck?

Direct Answer: You can completely clear attic roof sheathing mold and satisfy buyer reinspection within 48 hours using cryogenic dry ice blasting (-109.3°F) and botanical antimicrobial sealing, followed by raking back insulation and installing continuous rafter ventilation baffles.

Direct Answer: You can completely clear attic roof sheathing mold and satisfy buyer reinspection within 48 hours using cryogenic dry ice blasting (-109.3°F) and botanical antimicrobial sealing, followed by raking back insulation and installing continuous rafter ventilation baffles.

In Pennsylvania winters, warm indoor air rising into an unventilated attic condenses against freezing roof sheathing. Dry ice blasting removes fungal hyphae roots without adding liquid moisture. An independent PRV air clearance report delivers full underwriting compliance.

The 48-hour Lehigh Valley attic protocol:

  • Negative Air Containment: Seal attic hatch with 6-mil poly airlock and run HEPA air scrubbers.
  • Cryogenic Dry Ice Blasting: Blast CO2 micro-pellets at 300 PSI to strip mold off roof decking.
  • Baffle Installation: Rake back insulation and install rigid PVC rafter baffles.
  • PRV Air Clearance: Independent lab certifies Condition 1 normal fungal ecology.

Call our Allentown emergency unit (or connect with our local Allentown mold testing crew) at (855) 215-6261 for immediate clearance.

As a PA inspector: Blocked soffits cause 80% of attic mold in the Lehigh Valley. Once baffles are in place, natural convection keeps the roof deck dry permanently.

Update: Blasted yesterday, 20 baffles installed, and PRV lab report was spotless! Lender cleared the loan for closing on Friday!
