Have you ever looked up at a roof and wondered what the overhang is called? You might not give it a second thought, but knowing the answer to this question can come in handy when you’re designing or building your own home. The overhang of a roof is an important architectural element that serves several useful purposes.
So, what is the overhang of a roof called? It’s called the eave. The eave is the horizontal edge of a roof that extends beyond the exterior wall of a building. It provides shelter from rain and sun, while also helping to prevent water from seeping into the walls and foundation. Additionally, the eave can add aesthetic value to a structure and help create a defined look or style.
Whether you’re buying a home, building one, or just curious about architecture, knowing the various terms and elements that make up a house can be helpful. The eave is just one of many important features that can make a significant difference in the overall appearance and functionality of your roof. Understanding what the eave is and how it works can give you a deeper appreciation for the art and science of architecture.
Parts of a roof
Before diving into what the overhang of a roof is called, let’s discuss the different parts of a roof. A roof can be broken down into several components that work together to provide protection from the elements for the occupants of a building. Here are the main parts of a roof:
- The roof deck: This is the base layer of the roof that the other components are installed on.
- The underlayment: A layer of material that is placed on top of the roof deck to provide an extra layer of protection against water intrusion.
- The shingles or roofing material: This is the visible layer of the roof that provides the main protection from the elements.
- The flashing: A piece of material that is installed around the edges of the roof, as well as around any openings, to prevent water from seeping in.
- The gutter system: This collects rainwater that falls on the roof and directs it away from the building.
Each of these components is crucial to the overall function of the roof. Without any one of them, the roof would not be able to provide shelter from the elements effectively.
Roof overhang terminology
Understanding the terminology related to roof overhangs is essential when planning, constructing, or renovating a building. Here are some of the most commonly used terms:
- Eave: The overhanging lower edge of a roof that projects beyond the wall of the building.
- Fascia: A straight board attached to the lower ends of the roof rafters, which covers the ends of the rafters and provides a surface for attaching the gutters.
- Soffit: The underside of the eave, which is usually finished and contains vents to allow air to circulate in the attic space.
Additionally, different regions may have their own unique terms for roof overhangs. For example, in some parts of the United States, the eaves may be referred to as cornices.
It’s important to note that roof overhang terminology can also differ between different types of roofs. For instance, a flat roof may not have eaves or a fascia board, while a gabled roof may have more than one eave and fascia board.
Common materials used for roof overhangs
There are several materials commonly used for constructing roof overhangs, each with their own benefits and drawbacks. Here are a few examples:
- Wood: This traditional material adds a classic, rustic look to the building. However, it requires regular maintenance and can be prone to rot and insect damage over time.
- Vinyl: An increasingly popular choice due to its low maintenance requirements and easy installation. It’s also available in a wide range of colors and styles.
- Metal: Durable and long-lasting, metal overhangs can be made from materials such as aluminum, steel, or copper. They’re also fire-resistant and can be painted to match the building’s exterior.
Calculating the size of a roof overhang
The size of a roof overhang will depend on several factors, including the climate and the size of the building. In general, a deeper overhang will provide more shade and protection from the elements.
| Roof pitch | Minimum overhang | Optimal overhang |
|---|---|---|
| 12:12 or steeper | 6 inches | 12 to 18 inches |
| 4:12 to 9:12 | 12 inches | 18 to 24 inches |
| Less than 4:12 | 18 inches | 24 to 36 inches |
It’s worth noting that building codes and homeowners’ associations may have specific requirements for the size and materials used for roof overhangs. Always consult with a licensed contractor or local authority before making any structural changes to your building.
Roof Construction Terms
Building a roof requires various terms that experts use to explain different parts of the structure. Understanding these terms can help homeowners during the planning and construction process. Among the terms that people should know is the overhang of a roof. But first, it’s essential to understand other significant terms that experts use during the construction process.
The following are important terms that experts use in roof construction:
- Ridgeboard: The ridge is the highest point of the roof, and the ridgeboard is the element that runs along the top of the roof capped by shingles or roof tiles.
- Rafters: These are the sloping beams that support the roof’s weight and transfer the load to the walls.
- Decking: This is the foundation of the roof, and it covers the rafters. The decking serves as a base where the roofing materials like shingles, tiles, or metal sheets lay.
- Valley: The intersection point of two roof planes forming an inverted V. The valley directs water off the roof by directing it to the gutters.
The Overhang of a Roof
The overhang of a roof is also called an eave. Think of it as the edge of the roof that juts out from the walls. Its primary purpose is to offer shade and prevent rainwater from running down the walls. Additionally, it serves as a protection for the foundation and protects the roof from being exposed to harsh weather elements.
The overhang of a roof varies depending on the standards. Normally, it is between six and twelve inches wide. However, some homeowners prefer a more extensive overhang, leading to the creation of a soffit. A soffit is a horizontal element that links the wall and the overhang of the roof.
It is also critical for homeowners to remember that the overhang of a roof requires adequate support to handle its weight. The structure that supports it is called the fascia, which is the board fixed to the ends of the roof’s rafters. It provides support to the roof’s gutter system and helps prevent moisture damage from the roof’s edge.
The Gable and Hip Roof
The gable and hip roofs differ mainly from their shapes and designs. The gable roof is an A-shaped structure, while the hip roof forms a more pyramid-like structure. Both roof types have an overhang, but the gable roof has a longer one due to its triangular shape. It is also easier to install a gutter system on a gable roof than a hip roof because of the structure shape.

Overall, these terms and definitions are critical for homeowners who plan to build or work on their roofs. Understanding them helps homeowners make informed decisions, choose the right materials and avoid costly mistakes in the process.
Eaves and Roof Overhangs
When it comes to roofing, eaves and roof overhangs are two important concepts to understand. Eaves are the edges of a roof that overhang a building’s exterior walls, while roof overhangs refer to any protrusion from the roof’s edge.
- What are eaves? Eaves serve an important functional purpose, preventing rain and other elements from running down the side of a building. They also help provide shade to the windows and walls of a building, reducing the amount of direct sunlight that enters the interior.
- Types of eaves: There are several different types of eaves, including closed, open, and boxed eaves. Closed eaves are lined with the roof’s material and have no visible soffit, while open eaves have visible rafters and an exposed soffit. Boxed eaves have a solid soffit installed beneath the rafter tails.
- Importance of eaves: In addition to their functional and aesthetic purposes, eaves also help protect a building from moisture damage by keeping rainwater away from the walls and foundation. They also provide a space for exterior lights and other fixtures to be mounted.
Roof overhangs, on the other hand, can serve a variety of purposes beyond protection from the elements. Here are some things to consider about roof overhangs:
- Purpose: Roof overhangs can be used to provide shade to outdoor living spaces, protect windows from direct sunlight, and improve a building’s energy efficiency by blocking solar heat gain. They can also add visual interest to a building, creating a more dynamic silhouette.
- Design considerations: When designing a roof overhang, it’s important to consider factors like wind conditions, snow load, and the weight and placement of any fixtures or accessories that will be attached to it. The size of an overhang will also affect the amount of shade provided, as well as the amount of rainwater that’s directed away from the building.
If you’re looking to install or repair your roof’s eaves or roof overhangs, it’s important to work with a professional roofing contractor who can help you choose the right materials and design for your needs. By understanding the benefits and design considerations of these two roofing features, you can make more informed decisions and ensure that your roof is both functional and beautiful.
| Type of Eave | Description |
|---|---|
| Closed eave | Lined with the roof’s material and has no visible soffit |
| Open eave | Visible rafters and an exposed soffit |
| Boxed eave | A solid soffit installed beneath the rafter tails |
By understanding eaves and roof overhangs, you can make more informed decisions about your roofing needs and create a more functional and beautiful home.
