Bonnet Roof vs. Gambrel Roof: Which Design is Right for You?

When it comes to choosing the right roof design for your home or building, two popular options often come into play: the bonnet roof and the gambrel roof. Both styles have distinct advantages and aesthetics, making the decision process quite nuanced. In this article, we’ll explore the features, benefits, and considerations of each roofing type to help you determine which design suits your needs best.

Understanding Bonnet Roofs

A bonnet roof, sometimes referred to as a double-pitched roof, features two slopes on each side, creating a shape similar to a bonnet. The upper slope is steeper, while the lower slope is more gradual, often extending past the walls of the building. This design is commonly seen in traditional American architecture and offers unique aesthetic and functional benefits.

Key Features of Bonnet Roofs

  • Design Aesthetic: The bonnet roof’s unique shape adds character and a sense of elegance to a structure.
  • Extra Space: The overhang allows for additional covered outdoor space, which can be useful for porches or patios.
  • Water Drainage: The dual pitch facilitates effective water drainage, reducing the risk of leaks.
  • Material Versatility: Various roofing materials, from shingles to metal, can be used effectively on a bonnet roof.

Delving into Gambrel Roofs

The gambrel roof is often recognized for its distinctive barn-like appearance. This style features two slopes on each side, where the lower slope is steeper than the upper slope. The gambrel roof design maximizes vertical space in the attic, making it a popular choice for homes that require extra storage or living areas.

Key Features of Gambrel Roofs

  • Spacious Attic: The design allows for more usable space in the attic, making it ideal for conversions into living areas or storage.
  • Classic Barn Look: This roof style is synonymous with rustic charm, often found in countryside homes and barns.
  • Effective Water Drainage: Similar to the bonnet roof, the design facilitates effective drainage, reducing maintenance issues.
  • Cost-Effective: Generally, gambrel roofs can be more affordable to build compared to more complex roof designs.

Roofing a gambrel design can seem daunting, but with the right guidance, it becomes manageable. Here’s a basic overview:

Steps to Roof a Gambrel Roof

  1. Prepare the Framework: Build the gambrel roof frame, ensuring both pitches are accurately measured.
  2. Install Underlayment: Lay down a moisture barrier to protect against leaks.
  3. Shingle Installation: Use shingles or metal roofing, starting from the bottom and working your way up to ensure proper water runoff.
  4. Finish Edges: Secure the edges with flashing to prevent water intrusion.

Cost Comparison: Gambrel Roof Cost vs. Normal Roof Designs

One significant factor when choosing between a gambrel roof and other styles is the cost. Generally, gambrel roofs can be more cost-effective than complex designs like mansard roofs, while also providing ample attic space.

In recent years, more homeowners have considered using a metal roof on their gambrel designs. Metal roofs provide numerous advantages, such as longevity and durability, making them an attractive option.

Benefits of Metal Roofing

  • Longevity: Metal roofs can last 40-70 years with minimal maintenance.
  • Energy Efficiency: They reflect heat, potentially reducing energy costs.
  • Lightweight: Easier to install compared to traditional materials.

Shingle a Gambrel Roof: Key Considerations

If you decide to shingle a gambrel roof, it’s essential to consider both the aesthetics and practical implications.

Shingling Tips

  1. Select Quality Materials: Opt for high-quality asphalt shingles or consider architectural shingles for added durability.
  2. Mind the Pitch: Ensure the pitch is suitable for the selected shingles to prevent issues with water drainage.
  3. Professional Help: If unsure, hire a professional for installation to avoid mistakes.
