Metal Roofing is a new option, both in new construction and when the roof of old age needs to be replaced. Metal Roofing products can be made from various metals, including galvanized steel, copper, aluminium or tin, and they can use many different installation systems.
The metal beats traditional roofing material in several ways:
Expected Life: Appropriately installed, sealing the metal from the roof to the house, sealing the water, surviving in high winds, and easily restoring the snow. Metal fire, mildew, insects, and rot are resistant. Warranty varies widely, but most companies withdraw their products for 20 to 50 years. Paint finish is usually 30 years limited warranty.
Weight: The Metal Roofing is very light. Due to the light weight of the material, you can build engineering and auxiliary structure. In fact, if you are building house or spare, you can often reduce or decrease the number of roof support members.
Some types of Metal Roofing material can be applied without tear on the existing roof or without the need for additional structural support.
Speed & ease of roofing installation: Most Metal Roofing materials come in many multiple-shingle sections or in wide panels of 12 to 36 inches. A complete contractor can install them quickly. If your roof is snatched and a storm is on the way, then one can provide a significant benefit for a day or two to reduce the process. Obviously, if you can reduce the period of installation of the roof and reduce it, then there is considerable labor savings.
Fire Resistance: Since Metal Roofing material is non-combustible, it is generally class A fire rating (most fire-resistant rating). Just be aware that the part of the overall classification of the roof depends on the material under the surface, which can also cause a fire in the warm summer. Most metal roofs are applied to a combustible material such as wood horns with the following reason; due to this reason the class C rating see the notes under “Metal Roofing Drawback” about problems in home fire conditions.
Heat conduction: Metal reflects the sunny heat from the sun, which reduces the benefit of the heat of the afternoon. This means that you save the energy needed for air conditioning during the day. Although the material itself is low in insulation R-value, the Metal Roofing can be applied to hard foam insulation, which has a lot of R-value. In addition, many systems use a dead air space between the metal and the roof deck to increase energy efficiency.
Minimum roof pitch:Most Metal Roofing materials can be installed on roofs gradually without leaking. The minimum roof pitch is usually 3-in-12 (the roof rises 3 inches for each horizontal leg).
Maximum shedding of rain and snow: Metal roof is practically indecipherable for rain and snow due to the interval of the panels and the surfaces are hard and slippery. In addition, encouraging the snow roof, the dark tones of the metal roof are hot in the snow early.
