Roof Installation 101: Understanding The Different Layers And Components

Each component, each layer of your roof, is a testament to architectural mastery that has evolved over centuries. Roofing isn't merely about slapping on some shingles — it's a delicate ballet of materials orchestrated to guard your home against nature's wrath. 

Intrigued? Take a look at the different components of a roofing system and how they fit together. 


The term "rake" in roofing refers to the inclined outer edge of a roof that runs from the eave to the ridge. From a structural perspective, the rake provides the necessary slope for rainwater drainage, preventing it from pooling on the roof surface. It also supports the shingles, underlayment, and other roofing materials, ensuring they stay in place.

Aesthetically, the rake forms part of the roof's silhouette and contributes significantly to the overall appearance of the house. It can be customized in various styles, such as a straight or curved edge, to enhance the architectural design. For instance, a steeply pitched rake might be used in traditional or Victorian-style homes, while a flat or sloping rake might be preferred for modern designs.

Furthermore, the rake is also about function and protection. The outer edge of the rake is often fitted with a metal or plastic covering, known as rake edge flashing. This crucial component provides an extra layer of defense against wind-driven rain, ice dams, and critters, preventing them from seeping into the roof's underlayers and causing damage. 


Trusses are essentially the framework that supports the entire roof, composed of triangles linked together to form a stable and rigid structure. The triangular design distributes the weight of the roof evenly across the structure of the house, allowing for larger spans without the need for any internal load-bearing walls.

Trusses are usually made of wood or steel, with the choice of material largely dependent on the architectural design, load requirements, and local climate.

The design of the truss can vary widely depending on the style and needs of the building. Some of the common types include the attic truss, scissor truss, and bowstring truss. Each truss type is suited to different roof styles, with gable roofs working best with most types of trusses, while hip roofs are generally better served by attic or bowstring varieties.

Trusses are not only integral to the structural integrity of a roof, but they also play a significant role in defining the interior aesthetics of a home.

They can create unique architectural features inside the house, especially when left exposed in cathedral ceilings or open-plan spaces. The space between the trusses, often filled with insulation, can also provide an effective barrier to heat loss, contributing to the home's energy efficiency.
