Why the assessment matters
No two roofs or enclosed spaces behave exactly the same
Roof profile, access, solar exposure, existing vents, moisture sources and the desired result all influence the right response.
Practical: start with the real conditions.
Technical: separate airflow issues from other building problems.
Honest: explain limits instead of promising a universal result.
