This article explores the diverse range of roof types, their characteristics, and ideal applications.

Exploring the Diversity of Roof Types

Ideal Use: Popular in historic buildings and residential structures seeking additional living space in the attic.

Ideal Use: Frequently found in residential properties, providing ample space for a loft or attic.

Ideal Use: Suitable for areas prone to high winds or hurricanes due to its aerodynamic shape.
