Roofing is one of those things in a home that everyone needs but nobody likes to discuss. A roof is usually the highest covering of a structure, featuring structures and materials used to support it on top of poles, buildings, or on upper risers, offering protection from sun, rain, wind, extremes of heat, and cold. A roof covering is often a large part of a building envelope. Some roof covers such as gables have overlapping slates which allows water to drain from the roof more easily and some other roof cover such as tiles or slate may feature slabs or pieces that are not used as regularly, with the space being available for covering other items of furniture or fixtures.
Roofing materials are often diverse, although there are standard roofing materials such as asphalt shingles, clay tiles, and rubber slate tiles. Other materials include wood shakes, gravel, gypsum board, ceramic tile, asphalt block, slate tiles, ceramic tile pavers, metal roofing, and slate tiles. Each type of material has its own advantages and disadvantages when compared to one another so it’s important to understand how each type works, why they work, and how they are best used for a specific roofing application. This article will discuss the types of materials commonly used in commercial and residential roofs.
The most commonly seen roofing materials are asphalt shingles and concrete tiles. With asphalt shingles, the materials are compressed together under high pressure and are then laid on top of asphalt. Asphalt shingles are the most commonly used roofing material because of their ability to be molded into any shape imaginable. Concrete tiles are very durable, but they don’t offer the aesthetic appeal of shingles due to the wide range of colors available in concrete tiles. It’s up to the homeowner to determine what type of look is desired and what type of roofing material will work the best in their particular situation.
Another common roofing material is flat roofs. A flat roof may consist of single levels or could have different levels of insulation. A flat roof may be self-supporting or require additional reinforcement elsewhere. Many flat roofs are built on slant roofs, which are ones with a steeply pitched roof. Other flat roof materials include leaf screens and gables. Gable roofs are typically placed on higher levels than other flat roofs, such as slanted roofs, and have an “L” shape to them.
There are also two other types of flat roofs; those that are normally used as green roofs, as well as those that are made with an inner layer of insulation. Green roofs are usually built with a soil base and allow rainwater and snow to run off of the roof efficiently. Insulated green roofs have a liner within the membrane, which is then filled with insulation. These are some of the different types of flat roofs available.
There are also a few special types of insulated roofs. In some situations, concrete tiles would be the best option, especially around swimming pools. Concrete tiles are very effective at conducting heat away from the pool, but they do have some drawbacks. Generally, concrete tiles are more expensive than other materials, such as felt, clay or bamboo shakes, asphalt shingles, or other forms of insulation.
