Rafters vs. Rafters and trusses are both structural components that frame the roof. Rafters are framing boards that extend from the ridge to the wall plate and are usually built on site. Trusses are usually prefabricated off-site in a triangular webbing frame to provide support for the roof and exterior walls.
Roof decking (also known as roof sheathing) is the wooden boards (plywood or planks) that make up the framing of your roof. It's the foundation of your entire roof system and what your roofing materials are installed on.
Rafters are the traditional way to frame a roof. This is also known as stick framing, which is cut and built on the job site by a professional carpenter. Major components of a rafter include: Common rafter.
The fascia board is the one mounted at the point where the roof meets the outer walls of the house and is often called the ROOFLINE. However most people refer to it by the name of the main board that carries the gutter – the fascia or fascias.
Decking. Also known as roof “sheathing,” roof decking provides support and an anchor for roofing materials. Laid on top of the rafters, decking is typically made from half-inch plywood or strand board (OSB).
Rafters are put from one end of the roof to the other and will act as a support system for all the other components. The outer rafters at the extreme ends of a roof are called "common rafters" while the ones between those are called "roof rafters".
The fascia is a long wooden board that runs horizontally on the edge of the roof. Usually, a fascia is either 2×8 or 2×6.
So what exactly are fascias & soffits? They are both parts of the exterior trim of a property, along with doors, windows and gutters. The fascia, often known as a fascia board, is a long piece of material, most commonly wooden, that runs underneath the roofline.
Both soffits and fascias make up your roof trim.
Siding. Siding refers to the layer of material placed on the outside or exposed area of a house. Siding comes in a variety of materials, including vinyl, wood, stone, brick, metal, aluminum, and synthetic options.
Framing lumber refers to the grade of lumber that is used in the process of framing a house. Similarly, structural wood is another name for framing lumber. Because of its technological features, it is well suited for usage in circumstances requiring extensive spans.
There are two common ways of framing the roof of a house: with pre-manufactured trusses, or with rafters and ceiling joists, commonly called stick framing.
Rafter. Rafters make up the basic frame to support the incline and siding of your roof. These angled timbers hold up your roof deck and provide your roof cover's main support. They are often connected by crosswise beams.
Roof decking, or sheathing, is the strong layer of wood that is laid on top of the rafters and becomes the base layer for any roof covering. Decks are most often made of plywood sheets or stand board (OSB).
OSB (Oriented Strand Board) – this type of board is made up of layers of wood strands that have been compressed and bonded together with resin. It is strong and stable, making it a popular choice for flat roofs. Plywood – this type of board is made up of layers of thin sheets of wood that have been glued together.
Fascia: The fascia are boards attached to the edges of the roof. The boards run horizontally and support gutters and drainage pipes. Decorative boards beautify the appearance of the house. Keeping gutters clean preserves the integrity of the fascia and soffits.
Fascia and trim can be made from similar materials, such as wood or vinyl, but their applications and locations differ significantly. Trim is used along most edges of the roof, while fascia is only installed on the lower roofline and eaves. The terms "trim" and "fascia" may sometimes be used interchangeably.
Fascia board replacement typically costs between $7 and $22 per linear foot, with an average of around $14.60, including materials and labor.
Roof sheathing (also called roof decking) is the wooden boards that make up the framing of a roof system. These boards are what your shingles and other roofing components are installed directly on. There are two types of roof sheathing, plank and sheet.
The sheathing (also known as decking) is the layer of flat wooden boards that attach to your home's rafters or trusses. The most common materials used for sheathing are plywood and oriented strand board (OSB). Roofers use a nail gun to secure individual panels down, making your roof into one cohesive unit.
[2018 WFCM] RIDGE BOARD
A NON-STRUCTURAL member used at the ridge of a roof to provide a common nailing surface and point of bearing for opposing roof rafters. Simply put, a ridge board is a non-structural nailing board located at the peak between the tops of the rafters.
Decking forms the foundation of your roof. It's usually made of plywood or OSB (oriented strand board). This layer provides structural support and holds the nails for shingles and other materials. What is the wood under the roof called? It's the decking or sheathing.
Ceiling moulding, also known as crown moulding or cornice, runs along the top of a room where the wall meets the ceiling. It softens the transition from wall to ceiling. Crown moulding can be simple or intricately detailed. These types of moulding trim can make a room look polished.
A rafter is a key structure in a roof, along with purlins and joists. Together, they make the framework of the roof. If you imagine your roof with no tiles or covering on, the rafters are the pieces of timber that slope vertically from the top down to the eaves. Rafters are generally laid side by side.
