Standing Seam Metal Roof
The primary characterization of a standing seam metal roof is the raised interlocking seams between panels that allows water to run off without seeping between the panels. Metal roofing hold a number of other advantages. They are very resistant to fire, water, wind and hail. They are energy efficient in that they will readily reflect the sun, thereby saving on cooling costs. They are also low maintenance. They can be easily installed on top of existing roofing such as asphalt or coal and tar, saving on removal and dumping costs. Metal roofing Houston is often used for large buildings due to its strength to weight ratio. Painted metal roofs can also shed snow and ice quite easily making it particularly useful in colder climates. Metal is also easily recycled and the recycling process is very efficient. Finally, a metal roof such as a standing seam metal roof is very durable often with a lifespan three times that of an asphalt shingle roof.
A gable roof has the triangle shape common to many roofs. The shape of the gable is determined by the underlying structure used, often due to climactic factors, and aesthetic reasons. The use of gable style roofing has a long history with many variations found in modern architecture. Advantages include ease of installation which in turn tends to make it a cost effective choice. Most Houston metal roof contractors prefer installing metal roofing on a gable style roof. It does not require the more complex structure of a hip roof, for example. The metal roof also tends to get a lot of style points due to the many possible variations. Living space underneath a gable roof is more easily optimized than some other roof types.
Unfortunately gable roofs have some distinct disadvantages. They are a bad roof type to have in high wind conditions such as a hurricane. The shape of a gable roof resembles that of an airfoil, the more so with a shallower slope, and wind moving across it will try to lift it similar to the wing of an airplane. This is mitigated somewhat by a steeper angle roof which will “stall” the wind and prevent the airfoil effect. Overall the gable roof is a very popular choice used in many architectural designs.
Corrugated metal roofing can be made from a variety of materials including plastic and fiberglass but is most commonly made of metal. Reasons for corrugation include increase of strength in the roofing sheet and aesthetics. Corrugated roofing materials tend to have a good strength to weight ratio while staying quite flexible. Non-metal roofing can be used to let light shine through. Fiberglass corrugated roofing does carry some disadvantages. It does not insulate very well against heat or cold. Because of its thin light nature it can be very loud in rain. It can also rip off more easily in high winds than heavier types of roofing. Ultimately, while corrugation of roofing sheets does offer some benefits, the larger part of associated advantages and disadvantages lie with the type of material from which the corrugated roofing is made.
A hip roof is a roof type where all sides of the roof slope down toward the walls. On a square building a hip roof will look like a gently sloping pyramid. The advantages of a hip roof include the ability to put eaves troughs on all sides thereby sparing the walls some weather wear and tear. A distinct plus for the hip roof is that it stands up much better against wind storms such as hurricanes because it does not produce the ‘air foil’ effect that the more conventional gable roof can in very windy conditions. In the U.S. some windstorm insurance companies will give premium discounts to customers who can prove they have a hip roof. A hip roof is also self-bracing not needing the additional wind-bracing that a gable roof does. A possible disadvantage of the hip roof is the smaller amount of living space right below it. However, the advantages of a hip roof tend to outweigh the disadvantages. Variations of the hip roof include the Mansard, the Gablet and the half-hip roof.
