A new roof is typically installed when building a house or adding a new structure, while a replacement roof involves tearing off the old one and putting up new materials. The key difference is that a replacement starts with demolition, which adds labor and disposal costs, whereas a new roof installation begins with a clean deck, making it simpler and often cheaper. Replacement also lets you address underlying issues like rotten sheathing or poor insulation that a new roof wouldn't have.
