Spraying paint is significantly faster and uses less labor time for large open spaces, but it is often more expensive overall due to the high volume of paint lost to overspray and the costly masking materials required to protect floors, windows, and trim. Rolling paint requires more manual labor hours, which increases labor costs, but it consumes less actual paint and creates a heavier, more durable film thickness. For occupied homes or small rooms, rolling is typically more cost-effective and practical.
