Have you ever asked yourself why metal roofing is gaining a lot of popularity in the global market? The primary reason is that people have begun to realize the benefits that come with this kind of roofs. Metal roofing has a few drawbacks like a high initial cost, a lot of noise while raining, denting, and some painted metals can either scratch, peel, chalk or even fade. Despite these few disadvantages of metal roofs, people still run for this kind of roofing material. The reason is that the advantages of metal roofs outweigh the cons. In fact, metallic materials beat out the conventional roofing materials in several ways. Below are some of the ways you stand to benefit by going for metal roofing materials.
A metallic roof can last as long as the house is in existence as long as you install it well. It should be able to seal out water, survive high winds, and shed snow with a lot of ease. Most metals are resistant to rot, insects, mildew, and even fire. Warranties vary, but reputable Metal Master Shops can give you between 20 to 50 years. Most painting finishes have a limited warranty period of 30 years.
Metal roofing is lightweight especially if you compare it with tiles or concrete. A broad range of metal roofing materials weights between 50 to 150 pounds per square. You can apply some kinds of metal roofs on an existing roof without adding any structural support or tear-off. For instance, if you are building or extending your house, you can reduce or downsize the number of roof supports.
Most of the metal roofing comes in 12 to 36-inch-wide panels or multiple shingles. It allows highly experienced contractors to do the installation with a lot of ease. Shortening the process has several advantages especially if the storm is around the corner or your roof is stripping off. You can save on building the supportive structure and the engineering because the material is lightweight.
Metallic roofing materials are noncombustible and hence have the class A fire rating which is the most resistant. However, a section of the overall classification of the roof depends on the materials that are beneath the surface that can ignite the intense heat. Applying a metal roof on combustible material like wood shingles will give it a low-class rating like C.
Metallic roofs minimize midday absorption of heat because they reflect the radiant sun rays. Therefore, you will be able to save air conditioning energy from the sun. Even though the material has a low R-value insulation, most of the systems use a dead-air space in between the roof deck and metal to enhance the efficiency of the energy.
You can install most of the metallic roofing materials on roofs that are gently pitched without exposing them to the potential of leaking. The minimum roofing pitch is 3 in 12 which means the roof rises three inches for each horizontal foot.
Metal roofs are specifically impervious to snow and rain because of the manner in which the panels interlock as they have hard and slippery surfaces.
