What Are Shingles on a House and Why Are They Important?
What Are Shingles on a House?
Shingles on a house are thin pieces of building material used for roof covering and siding on residential buildings.
They come in various materials such as wood, asphalt, and slate, and are attached in overlapping courses or rows.
The type of shingle affects the roof pitch and construction method, with some requiring solid sheathing on the roof deck while others can be installed on lath.
Shingles are not completely water-tight, so a minimum roof pitch of 4:12 is recommended.
In the United States, fiberglass-based asphalt shingles are the most common roofing material used for residential applications.

Did You Know?
1. Shingles on a house have been used as a popular roofing material for centuries. However, did you know that the word “shingle” actually derives from the Old English word “scindel,” meaning “thin piece of wood”? This origin hints at the original material used for shingles, which were indeed made from split wooden boards.
2. While commonly made from materials such as asphalt or wood, shingles have undergone some unconventional changes over time. In Iceland, for instance, they have a unique type of shingle called “tjaldur,” which is made from fish skin. Yes, fish! These fish skin shingles were historically used as an affordable and sustainable roofing solution.
3. One might expect roofs to be built with shingles as a protective barrier from external elements, such as rain. Interestingly, however, some traditional Japanese homes feature shingles solely for decorative purposes. In these instances, the shingles made from clay or ceramic are designed to mimic the appearance of real shingles without providing any functional benefits.
4. Have you ever wondered why some houses have shingles in an overlapping pattern, while others have a more uniformed appearance? Well, the choice of shingle arrangement often depends on the region and climate. In areas with heavy rainfall, overlapping shingles help enhance water runoff, while in drier climates, a more uniformed pattern might be preferred for aesthetic reasons.
5. When it comes to shingle installation, precision and craftsmanship are key. However, did you know that there are professional competitions where roofers compete to show off their speed and accuracy in shingle installation? These shingle installation competitions, often held at construction trade shows, can be surprisingly intense and entertaining to watch.
Introduction To Roof Shingles
Roof shingles play a vital role in any house as they provide both protection and aesthetic appeal. These individual overlapping elements come in various materials including wood, slate, metal, plastic, and composite materials. Even ceramic roof tiles are still popular in Europe and Asia.
The installation of shingles on a roof follows a specific pattern called courses, where each course overlaps the joints below. The type of shingle used can impact the roof pitch and construction method. Some shingles require a solid sheathing on the roof deck, while others can be installed on lath. Moreover, underlayment material is often utilized to prevent leaks during shingle installations.
Safety is a significant factor to consider when selecting shingles for a house. Certain shingles have higher fire ratings than others. For instance, wood shingles and organic-based asphalt shingles, due to their fire hazards, are less commonly used. However, it is important to note that no shingles are entirely water-tight. Hence, a minimum roof pitch of 4:12 is recommended.

Different Materials Used For Shingles
In the United States, fiberglass-based asphalt shingles are the most commonly used roofing material in residential applications. In Europe, these shingles are known as bitumen roof shingles or tile strips but are less prevalent.
The popularity of asphalt shingles is due to their affordability, ease of installation, and durability, lasting anywhere from 20 to 60 years. They are also recyclable in some areas.
Wood shingles are another popular choice, particularly in areas with a tradition of wooden buildings, such as Scandinavia and Central and Eastern Europe. These shingles are protected by natural oils in the cellulose structure. However, over time, these oils soften and get washed out, leading to shrinkage and rot. This exposes nail heads, allowing water to seep into the building and cause moisture damage. There are two basic types of wood shingles: shingles and shakes. Shakes are longer, thicker, and have a more textured appearance.
Slate roof shingles, also known as slate tiles, are relatively expensive to install but have exceptional durability. They can last up to 80 years, and with proper maintenance, they can even endure for up to 400 years. The primary failure of slate roofs typically occurs when individual slates lose their attachment and slide out of place or start to break up.
Other materials used for shingles include fiber cement, metal, plastic, cedar, and composites. Synthetic or composite shingles are designed to mimic the look of natural materials like wood, slate, or clay. Rubber shingles, made from recycled tires, are also available. These shingles offer increased durability, noise reduction, hail resistance, and high wind ratings if they have a tongue and groove fitting at the front edge of the design.

Installation And Construction Methods Of Shingles
The installation and construction methods of shingles depend on the type of shingle and the roof pitch. Some shingles require solid sheathing on the roof deck, while others can be installed on lath, which is a narrow strip of material. Underlayment material is often used during installation to prevent leaks and provide an additional layer of protection.
Wood shingles are typically cut using methods such as hand splitting, quarter-sawing, or plain-sawing. They are usually cut from green wood and then kiln-dried. In the United States, wood shingles are commonly made from cypress, redwood, or Western red cedar. The surface of wood shingles can be striated, left smooth by sawing, or slightly rough from hand splitting. Weatherproofing stain or paint is necessary to prevent wood shingles from bleaching to a grayish color over time.
The degree to which the shingle’s surface is exposed depends on the pitch of the roof. As siding, the degree of overlap is mainly for aesthetic purposes. However, when used as roof covering, the overlap plays a critical role in preventing water penetration and protecting the underlying structure.

Common Types Of Shingles And Their Characteristics
Among the common types of shingles, fiberglass-based asphalt shingles are the most popular in the United States due to their affordability, ease of installation, and longevity of 20 to 60 years. They are also recyclable in some areas.
Wooden shingles, though less common due to fire hazards, are still widely used in areas such as Scandinavia and Central and Eastern Europe.
Slate shingles offer exceptional durability, lasting up to 80 years and even longer with proper maintenance.
Fiber cement shingles, metal shingles, plastic shingles, and cedar shingles are also options that provide their respective benefits and characteristics.
A new type of shingle material made from a blend of asphalt, fiberglass, and other polymers has recently gained popularity. These shingles mimic the look of natural materials like wood, slate, or clay but offer the advantages of durability and affordability.
Rubber shingle roofs, made from recycled tires, are a sustainable option. They last twice as long as asphalt shingles but are about twice the price. Rubber shingles provide increased noise reduction, hail resistance, and high wind ratings when designed with a tongue and groove fitting.
Shingle Styles And Architectural Examples
The term “shingle style” refers to a mode of wood shingle-covered American domestic architecture that was popular in the 1870s and ’80s. Notable examples of this architectural style include Henry Hobson Richardson’s Sherman House and the Stoughton House. The shingle style was characterized by the extensive use of wood shingles as the primary exterior covering material, creating a distinctive and cohesive appearance.
Shingles play a vital role in protecting and enhancing the aesthetics of a house. They come in various materials, each with its own advantages and characteristics. The installation and construction methods vary depending on the type of shingle and roof pitch. Whether it’s the traditional appeal of wood shingles or the durability of asphalt or synthetic materials, choosing the right shingle is essential for a secure and visually appealing roof.
