Application Method

Assess and recommend improvements to attic ventilation to reduce moisture levels that attract wood-destroying organisms. Calculate required ventilation using 1:150 rule (1 sq ft ventilation per 150 sq ft attic floor) or 1:300 with vapor barrier. Identify inadequate or blocked ventilation. Recommend solutions: install ridge vents, add gable vents, install soffit vents, install turbine vents, or add powered attic ventilators. Ensure balanced intake (soffit vents) and exhaust (ridge/gable vents) for proper air flow. Remove insulation blocking soffit vents. Proper attic ventilation reduces moisture accumulation preventing wood decay and conditions favorable to wood-destroying insects. May require collaboration with roofing contractor or general contractor for installation.

Timing

Assess during initial inspection when wood-destroying organisms detected or moisture damage observed. Recommend corrections immediately.

Frequency

One-time assessment and recommendation. Re-inspect annually to verify improvements completed and functioning properly.

Preparation Required

Calculate attic square footage. Measure existing ventilation. Have moisture meter to document conditions. Prepare recommendation report. Knowledge of proper attic ventilation requirements.

Follow-up Required

Provide detailed written report with calculations showing ventilation deficiency. Recommend specific solutions with cost estimates. Follow up to verify improvements completed. Measure post-improvement conditions to verify effectiveness.

Safety Precautions

  • Work safely in attic and on roof
  • Use moisture meter and thermometer to document conditions
  • Ensure recommendations meet building codes
  • Coordinate with qualified roofing contractor
