Roof Types Glossary

Every home is built with a specific roof style, and each design influences drainage, ventilation, durability, curb appeal, and overall weather performance. This roof types glossary helps Florida homeowners understand the terminology behind many common roof structures found throughout the region.

Each roof style has its own characteristics, maintenance considerations, and performance features. Whether you’re reviewing an inspection report, preparing for a roof replacement, or simply learning more about your home, this guide provides clear and reliable explanations of various roof designs.

This glossary is organized alphabetically by roof style. You can scroll through the list to find a specific term, or skim the headings to explore different roof shapes and structures commonly referenced in inspection reports and roofing estimates. Browse the Roof Types Glossary below to better understand your home’s architectural structure and how its roof design supports long-term protection and performance when properly designed and installed in accordance with applicable building codes. Then visit our our Roofing Terms Glossary and Roofing Materials Glossary to complete your general roofing knowledge and get a head start on your next roofing project with SEC Roofing in Jacksonville.

A

A steep, triangular roof forming the shape of an “A.” This style sheds water efficiently and provides strong structural support when properly engineered. Although not widely used as a primary roof type in Florida, it can be designed to meet high-wind performance requirements when compliant with the Florida Building Code and applicable engineering standards.

B

A hip-style roof design with lower slopes that flare outward near the eaves, creating natural shade and excellent water runoff. Bonnet roofs can complement Florida homes by helping shield walls and outdoor spaces from sun exposure and heavy rainfall when properly detailed and drained.

D

A rounded or spherical roof known for its efficient load distribution and potential energy efficiency benefits. Dome roofs can be engineered to perform well in hurricane-prone regions, but they are less common in standard residential roofing because they require specialized design, framing, and installation methods.

A combination of a gable roof placed on top of a hip roof. This hybrid design can provide additional attic ventilation and architectural interest while maintaining stability when properly engineered. In Florida and other high-wind regions, framing details and fastening methods must comply with applicable wind-load requirements.

F

A low-slope roof often used on commercial buildings and some modern homes. Because flat roofs depend on controlled drainage and reliable waterproofing, systems such as TPO, PVC, EPDM, or modified bitumen are commonly used. Proper design, slope, and installation are especially important for Florida roofs due to frequent heavy rainfall and high humidity.

A roof with the gable end facing the front of the building. Often used for architectural emphasis on entryways or facades, a front gable roof can add curb appeal without changing the overall structural performance when framed and braced correctly.

G

A classic two-slope roof design that meets at a ridge to form a triangular gable at each end. Gable roofs are cost-effective, provide good attic ventilation, and are among the most common roof types for Florida homes. In high-wind areas, proper bracing, sheathing, and hurricane-rated fastening are important for wind resistance and code compliance.

A double-sloped roof often associated with barns or loft-style homes. The upper slope is shallower, while the lower slope is steeper, creating additional interior space. Gambrel roofs are less frequently used for coastal or high-wind Florida homes unless they are specifically engineered and constructed to meet local wind and structural requirements.

H

A roof with all sides sloping downward from a central ridge or peak. Because there are no vertical gable ends, hip roofs tend to distribute wind loads more evenly than some other roof shapes. When properly designed, framed, and fastened in accordance with the Florida Building Code and applicable engineering, hip roofs are widely regarded as a strong choice for homes in hurricane-prone areas.

M

A four-sided roof with two slopes on each side, where the lower slope is much steeper than the upper. Mansard roofs create additional living or storage space and offer a distinctive architectural look. Due to their complexity and multiple transitions, they require thoughtful design and careful installation in high-wind climates such as many parts of Florida.

S

A single-sloped roof commonly used on additions, porches, and modern-style homes. Shed roofs provide efficient water runoff and a clean, contemporary aesthetic. In strong-wind regions, including coastal parts of Florida, structural connections and fastening patterns should be designed to handle uplift forces in accordance with local codes.

V

Not a stand-alone roof type, but a critical intersection where two roof planes meet and channel water into a shared drainage path. Because valleys handle concentrated water flow, proper slope, underlayment, and metal flashing are essential to help manage heavy rainfall and reduce leak risk—especially important for Florida roofing systems.

Understanding your home’s roof style can make inspection reports, repair recommendations, and replacement conversations easier to follow. While this glossary provides general, homeowner-focused explanations, your licensed roofing contractor and design professionals should always be consulted for project-specific requirements, code compliance, and engineering details.

If you are considering a roof repair or replacement, reviewing your roof type alongside materials and terminology can help you ask better questions and feel more confident in your decisions. Roof design is only one part of understanding your home’s roofing system. For more homeowner-friendly explanations, you can also explore:
