Columbus Roofing: Article About Metal Roof Overview For Homeowners
For homeowners that live in severe weather conditions, metal roofing offers a suitable alternative to shingle based systems. Once considered a material strictly appropriate for business applications, today's metal options come in designer finishes and fashionable colors that can complement the home's color and style.
Energy efficient, this roof's smooth surface enables snow to easily slide down the slope without accumulating. For homeowners that live in snowy climates, upgrading to a metal roof can greatly increase the home's value. When properly installed by an experienced Columbus roofing contractor, a metal roof can last as long as the house does. Most manufacturers will back their products for 40 to 50 years due to its ability to seal out water and withstand heavy winds.
In addition, the insurance rates for home policies often go down after installation due to the roof's resistance to fire, insects, mold, mildew and even rotting. However, a roof's fire rating takes the materials that sit underneath the roof into consideration as well as the roof material itself. For example, laying a metal roof over the top of a cedar shake wouldn't protect against fire as well as if the prior roof was stripped of all combustible materials first. If laid over the top of asphalt shingles, the weight of a heavy snow can dent the metal panels from underneath.

Likewise, the condition of the insulation and ventilation in the attic play an important role in how susceptible the roof is to moisture and mold getting into the deck and supporting structures from the attic. While metal is tough and designed to shed water, resulting in fewer long term maintenance costs, cutting corners during installation by sidestepping needed upgrades or avoiding tear off costs can affect the overall protection of the roof.
Metal roofing comes in a wide variety of materials. Aluminum, tin, zinc, steel, galvanized steel and copper are popular options. Each metal gives the homeowner different characteristics and properties. Copper roofs, for example, last longer than other metals, but the price can be prohibitive. For that reason, copper is sometimes used on homes for specialized accents around windows or front porches.
Steel is more practical for both homes and businesses due to its lower cost. Due to its corrosive properties, galvanized steel offers the necessary protection from the weather. Heavy and more difficult to install, homeowners might prefer to pay a little extra for an aluminum roof instead. Aluminum also comes in shingles for those who want a natural look.
