 10 Types of roof design along with their functions and advantages:

1, Gable Roof: A gable roof consists of two sloping sides that meet at a ridge, forming a triangular shape at each end. It's one of the most common roof designs and provides excellent water drainage and ventilation. The steep slope allows for easy shedding of rain and snow, making it ideal for areas with heavy precipitation.

2. Hip Roof: A hip roof has slopes on all four sides, meeting at a ridge at the top. This design offers greater stability and durability in windy conditions compared to gable roofs. It also provides more attic space and allows for efficient rainwater drainage from all sides.

3. Mansard Roof: A mansard roof has two slopes on each side, with the lower slope being steeper than the upper one. This design maximizes interior space by providing additional headroom in the attic or upper floors. It's often used in historic or traditional architecture for its decorative appeal.

4. Gambrel Roof: Similar to a mansard roof, a gambrel roof has two slopes on each side, but the lower slope is steeper than the upper one. This design offers ample attic space and is commonly used in barns and Dutch Colonial-style homes.

5. Flat Roof: A flat roof has a minimal slope or no slope at all, making it appear flat. It's a cost-effective option and allows for easy installation of HVAC systems, solar panels, or rooftop gardens. However, flat roofs require proper drainage systems to prevent water pooling and potential leaks.

6. Shed Roof: Also known as a lean-to or skillion roof, a shed roof has a single sloping plane that slopes downward from one side of the building. It's a simple and modern design often used for additions, sheds, or contemporary-style homes. Shed roofs provide efficient water runoff and easy installation of roof-mounted equipment.

7. Butterfly Roof: A butterfly roof has two upward-sloping planes that meet at the center, creating a distinctive V-shape resembling butterfly wings. This design allows for large windows or clerestory openings along the center ridge, maximizing natural light and ventilation. Butterfly roofs are popular in modern and eco-friendly architecture.

8. Saltbox Roof: A saltbox roof features two asymmetrical slopes, with one side being longer and steeper than the other. It's a traditional New England-style design that provides added space for second-floor living areas or attic storage. Saltbox roofs offer architectural charm and efficient water runoff.

9. Dutch Gable Roof: A Dutch gable roof combines elements of a gable roof with a hip roof, featuring a gable at the top with hipped sides. This design offers the aesthetic appeal of a gable roof with the added stability and durability of a hip roof. Dutch gable roofs are commonly used in residential and cottage-style architecture.

10. Skillion Roof: Also known as a mono-pitched or shed roof, a skillion roof has a single sloping plane that slopes in one direction. It's a modern and minimalist design that offers architectural simplicity and efficient water drainage. Skillion roofs are often used in contemporary homes, cabins, or commercial buildings.

Each type of roof design has its unique functions, advantages, and aesthetic characteristics, making it important to consider factors such as climate, architectural style, and budget when selecting the most suitable option for a building project.
