š” Pro Tips
ā Common Mistakes to Avoid
š Troubleshooting
High energy bills despite new insulation
*Cause:* Air leaks not sealed or insufficient R-value
*Fix:* Perform blower door test and seal remaining leaks
Ice dams forming on roof
*Cause:* Heat loss through ceiling or inadequate ventilation
*Fix:* Improve air sealing and ensure proper attic ventilation
Insulation settling significantly
*Cause:* Over-compression during installation
*Fix:* Add additional insulation to restore R-value
