The bonnet roof, also known as a kicked-eaves or bell-cast roof, has a nuanced history deeply intertwined with French colonial and vernacular architecture. Though it is not as popular or widespread as other roofing styles, its distinctive design can be traced back to several historical structures, mainly in regions with French colonial influences.
This roof style typically showcases a double slope, with the upper slope having a lesser angle than the lower one. Over time, it found its place in the architectural blueprints of various cottages and bungalows, adding a quaint yet elegant touch to the skyline.
The bonnet roof’s charming aesthetics, paired with its functional advantages, cemented its place as a choice style for individuals seeking a blend of tradition and functionality.
What is its Purpose
The primary purpose of this roof style lies in its capacity to offer increased protection against the elements while providing additional living space. The double-sloped design, characterized by the extension of the lower slope, creates an overhang that offers substantial protection against rain and direct sunlight, safeguarding the building’s structure and enhancing its energy efficiency.
Additionally, the extended eaves create an opportune space for a porch or a shaded seating area, allowing homeowners to enjoy the outdoors irrespective of the weather. The unique design also facilitates better water runoff, minimizing the potential for water damage over time.
What Materials are Used in Bonnet Roof
- Asphalt Shingles: Frequently chosen for their affordability and ease of installation.
- Metal Roofing: Offers long-lasting durability and is resistant to many adverse weather conditions.
- Wood Shingles: Lend a rustic and organic look, enhancing the roof’s overall aesthetic.
- Clay or Concrete Tiles: Offer durability while adding a touch of classical elegance.
- Slate: A premium choice known for its long lifespan and luxurious appearance.
- Synthetic Roofing Materials: These modern alternatives mimic traditional materials but offer improved durability and maintenance features.
Methods to Repair
The repair of a bonnet roof necessitates a meticulous approach to maintain its unique characteristics and functionality. Routine inspections are crucial to identify and address issues like wear and tear or potential leaks at an early stage.
Since these roofs have complex structures with varying slopes, repairs can sometimes be quite intricate. It might involve the replacement of damaged shingles or tiles, addressing leaks, and ensuring the structural integrity of the roof is intact.
Given the complexity, it’s often advisable to engage professionals who specialize in such roofs for repairs and maintenance to ensure longevity and preserve the roof’s distinct features.

Advantages and Disadvantages
One of the distinct advantages of the bonnet roof is its aesthetic appeal, providing a quaint and picturesque quality to buildings. Its design also offers excellent protection against weather elements, thanks to the extended eaves that shield the walls from rain and provide ample shade. Additionally, the provision for additional living or leisure space, like a porch, enhances the functional utility of the structure.
However, the roof style is not devoid of downsides. Its complex structure can mean higher construction costs and a longer time frame for completion. Moreover, the varying slopes create pockets where water can accumulate, leading to potential leakage or damage if not properly maintained. This also implies that regular maintenance is a necessity, which can incur additional costs over time.
