A board roof or boarded roof [1] is a roofing method of using boards as the weather barrier on a roof. Board roofs can be applied in several ways, the basic types have the boards installed vertically and installed horizontally. Double board roofs were sometimes used on railroad cars. [2]
Vertical board roofs may have the boards installed in a number of ways. The board-on-board roof has two layers of vertical boards, the upper layer covering the gap between the boards in the lower layer. The lower layer may be spaced apart or installed tightly together.[ citation needed ] In any type of vertical board roof the boards may be grooved to catch runoff.
The board-and-batten roof the upper layer are slender pieces of lumber called battens. The lower layer of boards are installed tightly because the battens are narrow.
Traditional roof coverings in Japan are mostly thatch, tile and wood shingle but some board roofs were used and are called yamatobuki (大和葺), the boards themselves naga-itabuki (長板葺). [3]
The framing for a vertically boarded roof needs purlins spaced evenly apart instead of rafters. In parts on New England a common type of roof framing has common purlins which are boarded vertically, but evidence of these roofs having exposed boards as roofing is rare.
Animal shelters may have board roofs which are a single layer with small gaps between the boards to allow light and ventilation. Any leakage is minimal and does not bother the animals. [4]
Horizontal board roofs may be made with rectangular boards or wedge shaped boards called clapboard (architecture).
A roof is the top covering of a building, including all materials and constructions necessary to support it on the walls of the building or on uprights, providing protection against rain, snow, sunlight, extremes of temperature, and wind. A roof is part of the building envelope.
Timber framing and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect. The country most known for this kind of architecture is Germany, where timber-framed houses are spread all over the country.
Siding or wall cladding is the protective material attached to the exterior side of a wall of a house or other building. Along with the roof, it forms the first line of defense against the elements, most importantly sun, rain/snow, heat and cold, thus creating a stable, more comfortable environment on the interior side. The siding material and style also can enhance or detract from the building's beauty. There is a wide and expanding variety of materials to side with, both natural and artificial, each with its own benefits and drawbacks. Masonry walls as such do not require siding, but any wall can be sided. Walls that are internally framed, whether with wood, or steel I-beams, however, must always be sided.
Moulding, or molding, also coving, is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster, but may be of plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones. In historic architecture, and some expensive modern buildings, it may be formed in place with plaster.
Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.
A plate or wall plate is a horizontal, structural, load-bearing member in wooden building framing.
Roof shingles are a roof covering consisting of individual overlapping elements. These elements are typically flat, rectangular shapes laid in courses from the bottom edge of the roof up, with each successive course overlapping the joints below. Shingles are held by the roof rafters and are made of various materials such as wood, slate, flagstone, metal, plastic, and composite materials such as fibre cement and asphalt shingles. Ceramic roof tiles, which still dominate in Europe and some parts of Asia, are still usually called tiles. Roof shingles may deteriorate faster and need to repel more water than wall shingles. They are a very common roofing material in the United States.
A batten is most commonly a strip of solid material, historically wood but can also be of plastic, metal, or fiberglass. Battens are variously used in construction, sailing, and other fields.
A purlin is a longitudinal, horizontal, structural member in a roof. In traditional timber framing there are three basic types of purlin: purlin plate, principal purlin, and common purlin.
Shiplap is a type of wooden board used commonly as exterior siding in the construction of residences, barns, sheds, and outbuildings.
Domestic roof construction is the framing and roof covering which is found on most detached houses in cold and temperate climates. Such roofs are built with mostly timber, take a number of different shapes, and are covered with a variety of materials.
Sarking is an English word with multiple meanings in roof construction:
Pole framing or post-frame construction is a simplified building technique that is an alternative to the labor-intensive traditional timber framing technique. It uses large poles or posts buried in the ground or on a foundation to provide the vertical structural support, along with girts to provide horizontal support. The method was developed and matured during the 1930s as agricultural practices changed, including the shift toward engine-powered farm equipment and the demand for cheaper, larger barns and storage areas.
The Zigzag Ranger Station is a Forest Service compound consisting of twenty rustic buildings located in Oregon's Mount Hood National Forest. It was built as the administrative headquarters for the Zigzag Ranger District. It is located in the small unincorporated community of Zigzag, Oregon. Many of the historic buildings were constructed by the Civilian Conservation Corps between 1933 and 1942. Today, the Forest Service still uses the ranger station as the Zigzag Ranger District headquarters. The ranger station is listed on the National Register of Historic Places.
The Unity Ranger Station is a United States Forest Service compound consisting of five buildings and a lookout tower in the Wallowa-Whitman National Forest of northeastern Oregon. It was previously the administrative headquarters for the Unity Ranger District. It is located in the small unincorporated community of Unity, Oregon. The historic structures were built in the rustic style by the Civilian Conservation Corps between 1936 and 1938. Today, the ranger station is only used during the summer months to house Forest Service fire crews. The ranger station is listed on the National Register of Historic Places.
The Parker Training Academy Dutch Barn is located at that institution on Turkey Hill Road in the town of Red Hook, New York, United States. It is a wooden structure built in two stages between 1790 and 1810. In 2007 it was listed on the National Register of Historic Places.
Roofline is used to describe the fascia, soffits, bargeboards and antefixes that forms the frontage immediately below the roof and the eaves of many homes and buildings. These are traditionally made from wood, but can be made of a variety of different materials, including plastic, such as polyvinyl chloride.
Copper has earned a respected place in the related fields of architecture, building construction, and interior design. From cathedrals to castles and from homes to offices, copper is used for a variety of architectural elements, including roofs, flashings, gutters, downspouts, domes, spires, vaults, wall cladding, and building expansion joints.
The New England Barn was the most common style of barn built in most of the 19th century in rural New England and variants are found throughout the United States. This style barn superseded the ”three-bay barn” in several important ways. The most obvious difference is the location of the barn doors on the gable-end(s) rather than the sidewall(s). The New England and three bay barns were used similarly as multipurpose farm buildings but the New England barns are typically larger and have a basement. Culturally the New England Barn represents a shift from subsistence farming to commercial farming thus are larger and show significant changes in American building methods and technologies. Most were used as dairy barns but some housed teams of oxen which are generally called teamster barns. Sometimes these barns are simply called “gable fronted” and “gable fronted bank barns” but these terms are also used for barns other than the New England style barn such as in Maryland and Virginia which is not exactly the same style as found in New England. A similar style found in parts of the American mid-west and south is called a transverse frame barn or transverse crib barn.
American historic carpentry is the historic methods with which wooden buildings were built in what is now the United States since European settlement. A number of methods were used to form the wooden walls and the types of structural carpentry are often defined by the wall, floor, and roof construction such as log, timber framed, balloon framed, or stacked plank. Some types of historic houses are called plank houses but plank house has several meanings which are discussed below. Roofs were almost always framed with wood, sometimes with timber roof trusses. Stone and brick buildings also have some wood framing for floors, interior walls and roofs.
