Roof eaves are parts of a roof that extend beyond the exterior wall and serve aesthetic and functional purposes. These systems protect your home from moisture, keep animals away, and provide shade. Read more about the functions, types, and benefits of roof eaves below.

What Are Roof Eaves?

Roof eaves are designed to protect buildings from rain and snow, and also keep water from dripping directly down the walls and foundation of a house. Roof eaves run along the lower edges of roofs and extend horizontally from exterior walls.

Eaves are simple structures, but each variety includes different components:

• Fascia: The fascia is a horizontal panel that attaches to the ends of the rafters or trusses. It provides a surface for attaching the gutters and offers aesthetic appeal to any home.
• Flashing: A flashing is a metal element that prevents water from seeping into a building by directing it away from vulnerable areas. It sits at the junction of the roof and the eave. 
• Soffit: The soffit is the underside of the eave, which is usually made of panels. It covers the space between the exterior wall and the edge of the eave.
• Vents: Some eaves have vents that facilitate air circulation in an attic space and regulate temperature and moisture levels. 

Eaves aren’t a necessary part of a roof’s structure, but they can help preserve a building’s integrity.

History and Purpose of Eaves

Eaves have been a staple of roofs for thousands of years across different cultures. Eaves protected homeowners from the sun in ancient Greece and Egypt and kept water away from buildings as part of classic Chinese architecture. The earliest eaves were made of clay tiles, reeds, and palm leaves.  

Early iterations of eaves served exclusively functional purposes, but they quickly became used for aesthetic appeal, too. Architects added ornamental elements such as carved woodwork and decorative brackets to eaves to create distinctive appearances. Eaves also added depth to rooflines.  Contemporary roof eaves still serve primarily as protection from water, but they also make homes more energy-efficient by providing shade and reducing excessive heat levels.

Types of Eaves

There are many types of eaves from which you can choose if you’re planning to roof a house. Consider climate, budget, and your personal style preferences when deciding which type of roof eave is best for your project.

Read more about the most common options below.

Abbreviated Eaves

Featuring a shorter overhang compared to other types, abbreviated eaves are common in modern or minimalist architectural styles. They offer a sleek and contemporary appearance but limited protection from rain and sun.

Boxed Eaves

Also called boxed-in eaves or closed eaves, boxed eaves have a soffit and fascia that extend from the walls to the undersides of roof overhangs. This system creates a box-like structure around the eave and hides the rafters.

Boxed eaves offer a clean and finished appearance, protection from weather elements, and a barrier against pests. However, they require additional ventilation measures to prevent moisture buildup and present maintenance challenges.

Curved Eaves

Curved eaves feature a gentle upward curve or downward curve along overhangs. This slight curve adds a touch of elegance to a building’s design with a distinctive appearance. Curved eaves cost more than other eave types.

Open Eaves

Also called exposed eaves, open eaves don’t have soffit or fascia. They boast traditional and rustic looks that architects can leave unfinished or complete with decorative brackets.

Open eaves offer easy access for maintenance and are less expensive than other eave types. However, they provide less protection from the elements than other eave types and are vulnerable to pest intrusion. 

Soffited Eaves

Soffited eaves include a flat soffit underneath overhanging roof elements. The soffit connects the bottom edge of the roof to the building’s wall and protects the roof rafters. This eave system consists of panels or boards.Soffited eaves offer aesthetic appeal, customization options, and protection from weather elements. However, their closed design makes maintenance more challenging.

Eaves vs. Fascia and Soffit

Eaves, fascia, and soffit share similar qualities but are three distinctive elements of roofing systems and serve different purposes. Read more about the differences between them below.

Eave vs. Fascia

Fascia is a horizontal board or panel that’s attached to the ends of rafters and serves as a finishing edge for the eave. Fascia boards provide a surface for attaching the gutters and allow for proper rainwater drainage. Fascia helps to protect the exposed edges of a roof from moisture and pests.

Eave vs. Soffit

The soffit is the underside of the eave and covers the space between the exterior wall and the eave. It includes vents that allow for air circulation, which prevents the buildup of moisture and reduces mold growth. The soffit helps to maintain a balanced temperature in the attic, which prevents rot.Eaves, fascia, and soffit work together harmoniously. Eaves protect buildings from inclement weather, fascia acts as a support system for the gutters, and the soffit offers ventilation and keeps pests from entering your home.

Benefits and Drawbacks of Eaves

Eaves aren’t critical for every roofing system, and some owners avoid eaves to save on the cost of a new roof. Read more about the benefits and drawbacks of eaves below to help you decide whether eaves are right for you. 

Benefits of Roof Eaves

The main benefits of adding eaves to your roof include the following:

• Aesthetic appeal: Eaves make a home appear elegant. You can customize eaves with different materials, finishes, and decorative elements, depending on which type of roof you choose. This can potentially increase the value of your home.
• Energy-efficiency: Roof eaves can provide extra shade for a building’s windows and walls, which reduces the amount of direct sunlight that enters the interior. This reduces heat gain in the summer and cuts cooling costs.
• Pest control: Eaves with soffits can keep insects, wasps, birds, rodents, and other uninvited guests from settling into the attic or roof space.
• Ventilation: You can promote airflow in the attic by adding soffit to the eaves. This helps regulate temperature, reduce moisture buildup, and prevent mold growth. Proper ventilation can also extend the lifespan of roofing materials.
• Weather protection: The main benefit of installing a roof eave is to add protection from the elements. Eaves create an overhang that acts as an umbrella and keeps rainwater, snow, and debris away from a building’s walls and foundation. This helps to prevent water damage, moisture penetration, and erosion of a building’s exterior.

Drawbacks of Roof Eaves

Roof eaves benefit many homes, but they come with some drawbacks, too. Read more below. 

• Additional costs: Roof eaves can make a new roof installation more expensive and require additional materials and labor.  
• Maintenance: Eaves make roofing maintenance more complicated. Eaves require regular inspection, cleaning, repainting, and repairs.  
• Pest nests: Pests can easily enter or build nests under your roof if you don’t seal and maintain eaves properly. Avoid this by performing regular inspections and maintenance.  
• Wind uplift: Roof eaves can compound the risk of wind uplift for homes in windy areas.

Maintenance of Roof Eaves

Eaves require regular maintenance. Below are the tasks you should perform regularly. 

• Clean the eaves: Use a broom to remove dirt and debris from the eaves, and keep an eye out for cobwebs and pest nests. Finish by rinsing the eave with a garden hose. Be careful not to spray water into ventilation holes.
• Clean the gutter system: Clean the gutters at least twice a year. Overfilled gutters cause water to flow down the fascia and soffit, which can lead to damage.
• Conduct regular inspections: Visually inspect roof eaves at least once a year. Check for pests, debris, mold, and damage. You can inspect some parts of the eaves from the ground, but you may need a ladder to check other parts. Leave inspection to a roofing contractor if you don’t feel safe on a ladder.
• Paint the eaves: Paint roof eaves every three to five years. Materials may otherwise deteriorate and cause water to leak into your home. Failing to repaint wood eaves will make them vulnerable to sun damage, rain damage, and insect damage.
• Repair the eaves: Repair any damage you notice immediately. The longer you let a problem sit, the more likely it is to cause damage to your eave and home.

Our Recommendation

Roof eaves protect your home from moisture, improve its aesthetic appeal, and can contribute to energy efficiency, home value, and comfort, but they aren’t right for all homeowners. Research the different types of roof eaves before you commit to a model, ensure you have the budget necessary to make the investment, and consult a variety of professional roofers to make sure you’re getting the best deal.
