A roof is on the top of a building. The essential features of its design: material, construction and durability. There are a variety of materials used to build roofs. Straw, seagrass, banana leaves are some natural materials used. Laminated glass, precast concrete and aluminum sheeting are some man-made materials utilized. Construction depends upon the primary element of support. Durability is essential because the breakdown of these structures can lead to serious problems.
Roofs have many purposes. They primarily function as protection. They protect property and people from weather and outdoor elements. The structures can assist in drainage. Most have the ability to repel off water. Stagnant water on a rooftop can cause damage and be an inconvenience. Roofs insulate buildings. They prevent the passage of heat, cold, dirt and noise.
Roofers specialize in roof construction. In Australia they are also known as roof carpenters and in the United States they are sometimes called journeymen. The state of California requires contractors, who plan on doing extensive roofing, to participate in a roof-licensing process. Other than licensing requirements, which vary by location, roofers should have good balance, carpentry skills and no fear of heights. Those interested in expanding their skills can participate in training institutes. Most roofers learn their skills through experience, mentors or self-teaching. Still, institutes offer courses that go in depth on carpentry, techniques and materials. Generally, formal training is not required.
There are many different styles available when it comes to this building structure. Some examples: hip, pyramid hip, cross-hipped, gable and cross-gabled. Flat, shed, saltbox and gambrel are more examples. Deciding which style is suitable for your building is a matter of taste and effectiveness. Some people may consider consulting a contractor before making a decision.
A new innovation in roofing systems is solar roofs. These roofs usually incorporate solar shingles. These shingles are able to generate electricity through the sun. In advanced forms, these structures can produce electricity and recover thermal energy. Solar roofs, though complex, still serve the basic functions of other roofs.
There are several options available to construct roofing structures. These materials range from foam to metal, slate to shingles, tile to plants. Style of roof should be chosen before material. Some materials cannot be used on specific styles. When deciding on a material, consider cost, maintenance, building location, climate and desired appearance. If you are replacing an existing roof, keep in mind the current style and material you have.
Roofing is not only the construction and installation of roofs; it also involves maintenance and repairs. Problems with these structures can develop over time. Sometimes they are the result of lack of maintenance or bad installation. If a roof was installed incorrectly, it can shorten the lifespan of the structure. Not maintaining the structure can also affects its endurance. Some common roof problems: ridging, tending, blow-offs, splitting, leaks, blistering and billowing.
