Before you begin, it is important to understand the parts of a roof. These parts include the Gable, Soffit, Sheathing, Principal rafters, and Downspouts. The purpose of each component is to help the house remain dry. Below are a few of the most common and important parts of a roof. Read on to learn more. You’ll also learn about the different types of roofing materials used on different types of roofs.
Soffit
The Soffit of a roof is the overhanging edge of a roof. Vents installed in this area allow increased airflow into the attic, reducing the chances of ice building up on the roof during cold weather. The ventilation also helps keep the attic space cool during the summer, improving the overall comfort of the home. Soffit vents are a great way to improve the ventilation of your home, and 4 Weather Insulation & Roofing can help you achieve your desired results.
Sheathing
The sheathing on your roof is a critical part of your roof. Without it, your roof would be vulnerable to damage from high winds, falling tree branches, or natural disasters. Wood is often used for roof sheathing, and the choice you make will have a big impact on your roof’s structural integrity. Depending on the size and style of your roof, you may choose a lighter-weight material such as OSB or plywood for the sheathing.
Downspouts
Downspouts divert water away from the foundations of buildings. They may be simple bends or a more elaborate system that connects to a sewer or runoff water drain. In history, downspouts were first installed on the Tower of London in 1240, whose whitewashed exterior needed protection from rain. Sometimes, downspouts have decorative heads that are placed in areas where they are not normally seen.

Principal Rafters
In a roofing system, the main structural elements are the rafter and the wall plate. These rafters are laid in series and form the base for roof decks and other roof coverings. Rafters are typically made of timber or steel and can either be left exposed or covered with battens. In many instances, a roof will have both types of rafters. Listed below are some benefits of each type of rafter.
Ridges
Ventilating the ridges of a roof requires the installation of vents. These can be either horizontal or vertical. The horizontal vents provide air flow by deflecting the hot air from the roof. They can also be installed vertically, either on a hipped roof or a flat roof. These vents are essential to the ventilation of the hipped roof, as they are positioned high on the hipped roof.
Roofing Materials
The parts of a roof are the weather insulation & roofing materials. A roof consists of four parts: the decking, the eave, and the shingles. The decking is the structural base of the roof and usually consists of plywood, OSB, or wood plank. These parts are designed to support the weight of the roof and snow as well as any other load required by local building codes. When a roof slopes downward, the lower horizontal edge of the roof is called the eave. In some cases, the eave also refers to the underside overhang of the roof deck from the fascia to the outside wall.
