The core of any roofing system and parts of a functional roof begins with the roof structure, which provides the foundational support for all other parts of a roof.
Roof Decking and Gable Roofs
A roof deck, commonly referred to as roof decking, is laid out as a base for the roofing materials. One of the most prevalent materials used is asphalt shingles, due to their durability and cost-effectiveness. These shingles are installed over the deck to provide the primary water-shedding surface. For a gable roof, another popular design, the roof slopes downward on two sides, forming a triangle-like appearance. A critical component in ensuring water is directed away from the roof’s edges is the drip edge, which channels water off the sides, preventing potential damage to the underlying structures. Choosing the right roofing material or materials can be overwhelming for homeowners, but with the expertise of a seasoned roofing contractor, the process can be streamlined, ensuring a sturdy and long-lasting roofing system.
Parts of a Roof
Roof Deck: Typically constructed from plywood or oriented strand board (OSB), this layer provides the structural foundation for the roof covering and underlayment. A roof’s decking acts as a barrier against moisture which is also known as roof sheathing.
Underlayment: This is a protective layer, usually made of felt or synthetic materials, that sits between the roof covering and the roof deck. It acts as a barrier against water infiltration.
Roof Covering: One of the most important parts of a roof. This can be shingles, tiles, slate, or metal. It’s the outermost layer that protects against weather conditions.
Gutters and Downspouts: Gutters collect rainwater and channel it away from the foundation via downspouts. This prevents erosion and safeguards the foundation of the building.
Rafters and Trusses: These are the structural supports that hold up the roof and transfer its weight to the walls of the building. Rafters are individual beams, usually made of wood, that run from the peak of the roof down to its edges, while trusses are pre-fabricated structural units that support the roof deck.
Ventilation: Roof vents, ridge vents, and soffit vents all help to maintain a flow of air in the attic, preventing moisture build-up and heat accumulation.
Ridge: The ridge roof, where two roof planes meet, contrasts elegantly with the home’s horizontal line (or roof tiles) design elements, creating a harmonious balance of vertical and lateral architectural features.
Roof Valley: Where two sloping sections of roof meet to form a V-shape, it’s called a valley. They are crucial as they handle a significant amount of water runoff.
Roof Flashing: Made from metal or plastic, flashing is placed around roof protrusions to prevent water leaks such as chimney flashing or flooding in plumbing vents.
Drip Edge: A drip edge is a metal strip installed at roof edges to guide water off the eaves and into the gutters which can prevent leaks.
Roof Designs
Roof designs have evolved over the years to cater to different architectural styles, weather conditions, and aesthetic preferences. Here are some common types of roof designs:
Gable Roof: Gabled roofs, also known as pitched or peaked roofs, have a triangular shape and are among the most popular roof designs. This design can provide an attic space.
Hip Roof: All sides of this roof slope downwards to the walls, and it’s more stable than a gable roof. The sides are typically all equal length, forming a symmetrical structure.
Gambrel Roof: Similar to the Mansard, but it’s only two-sided. Common in barn houses, it’s often referred to as a barn roof.
Flat Roof: As the name suggests, these roofs appear flat but usually have a slight pitch to allow for water runoff. They’re commonly used in commercial buildings and modern homes.
Pitched Roofs: characterized by its sloping surfaces, not only offers efficient water runoff but also adds a classic architectural appeal to many homes.
Sloping Roof: A sloped roof facilitates effective drainage of rainwater, acting as an ice and water shield.
Types of Roofing Material
Asphalt Shingles: A primary roof covering and one of the most common residential roofs as they are cost-effective, easy to install, and come in a variety of colors. If you are looking for a roof with natural light, skylight flashing, which is made up of waterproofing material, is suitable for asphalt shingles.
Metal Roofing: A metal roof can be made from steel, aluminum, copper, or zinc. They are durable, fire-resistant, and recyclable, coming in panels or shingles.
