A roof is usually the covering top of a structure, containing all structures and materials required to support it upon the ground or on uprights, giving protection from rain, snow, sun, extreme temperatures, and wind among other things. The roofing, as with most other structures in a home, must be carefully considered and installed to provide the maximum amount of protection while also being easy to maintain. While some roofs last for decades or more, others are only good for a few years before needing to be replaced.
The most common type of roofing used in North America is the flat or conical roof structure. With this type of roof, rafters are placed in a conical shape around the outer edge of the home. Materials for a conical roof structure can include anything from asphalt shingles to tiles. However, one of the most efficient and least expensive types of this type of roofing is made from concrete. This type of roof has the following advantages over other options:
A conical roof allows snow and ice to slide off the roof easily because the slant of the roof eliminates any slope. This makes it an excellent choice for roofs in cold climates, such as those in Alaska and Canada. In addition, because there are no slopes to contend with, there is little chance for leaks and other types of damage that can occur with other types of roofs. This also allows for smaller roofs, such as those that cover bathrooms, kitchens, and other interior spaces, and can also work for multi-story buildings.
Another type of roofing that is less expensive than a conical roof but offers better insulation is a tile roof structure. This type of roof structure has several different types of tile used in it, which can range in color and size. This makes it easy to find tiles that will complement the existing structure of the home, as well as provide homeowners with the look they want. Tiles are the most effective at thermal insulating a home, although they may not be as durable or resistant to damage as shingles.
The third option, which offers thermal insulation as well as appearance, is a flat roof that is made from clay, concrete, gravel, or rock. Earth roofs have gained in popularity over traditional clay tile roofs over the past few years because they offer a cooler climate friendly option. These types of roofs have the advantage of being fire-resistant, have a flat surface, and are environmentally friendly.
However, flat roofs may be prone to drainage problems, especially if they slope towards the garage. In addition, these roofs may not be the best choice for colder climates because it often requires maintenance. Moreover, these roofs may require additional insulation to keep the heat inside the home. Finally, these types of roofs may not offer a sense of style to the home, although they are often among the least expensive options.
