The Different Types of Roofing
Roofing refers to the process of adding protective coatings to a structure to enhance its aesthetic appearance, but also to provide necessary protection from natural elements. Roofing may be defined as the roofing materials used to cover and strengthen the roof structure, including metal, asphalt shingles, wood shakes, stone aggregates, and concrete. The roofing system may include one or more roofing systems such as girders, trusses, and fascia, which are joined by hinges, tiebacks, shear boards, and valleys. A roofing system is usually a continuous membrane or sheet attached to the main building structure with through-bolts, screws, and nails.
A roofing material is any material that is used to add to the exterior of a structure, such as roofs, buildings, homes, or landscapes. Roofing is basically a roofing membrane, consisting of an asphalt layer. The asphalt roofing is then followed by a protective coating, which is usually comprised of rubber or a combination of resins and polyurethane. The roofing is usually part of the exterior structure, included in the construction package, which is why it’s often referred to as the exterior wall. If a structure has a completely open interior, a roof covering is not required, but if there is a door or windows, then an exterior wall is installed to enclose the open space.
There are two types of roofing systems; flat roofs and pitched roofs. Flat roofs consist of flat strips of asphalt or tar attached to the ceiling or the wall at the roof’s edge. Often, these flat roofs are built up as an extension of the home or business by adding interior wallpapered cavities that serve as insulation. The flat roofs are designed to conserve space and facilitate movement. A drawback of flat roofs is that they are susceptible to damage from ice accumulation, so it’s recommended that snow never accumulate on them.
Pitched roofs, on the other hand, are roofs that follow a prescribed pattern. These roofs are typically built using manufactured or pre-fabricated steel panels that have been rolled onto a foundation. In most cases, pitched roofs have an interior support layer as well, which is composed of gravel or crushed stone. The exterior face of these roofs is then covered with either asphalt or tar, depending on the weather conditions. In addition to being flexible, pitched roofs offer several advantages over flat roofs, such as their ability to slope gradually.
All roofs typically cost approximately 12% of the house’s overall value. There are many factors that influence this figure, including the type and number of rooms in the house, its age, existing condition, and its design. Older houses often cost more to install because of their limited appeal, while newer houses are less expensive due to their more appealing designs. Newer homes may also require more frequent maintenance, which increases the total cost of installation.
Wooden shakes are the most flexible type of roofing material, but also the most vulnerable to damage. Because they are constructed out of wood, they are subject to weathering and rotting. Although wood shakes can be installed by professional installers, they are not recommended for do-it-yourself projects because the increased risk of injuring yourself makes it risky to work on such projects without proper protective gear. Installing shakes is usually a better alternative than installing wooden roofs, because they are less likely to become damaged by wind and water. However, they are still vulnerable to damage, especially if they are situated in areas prone to heavy rain or snow.
