Metal roofing is usually manufactured in steel, copper, aluminum or stainless steel. It can be coated in a many different types and colors of paint and other coatings, making it as beautiful as it is durable. Modern metal roofing frequently carry warrantees of 50 years.
Metal roofing, which is manufactured and installed as panels, generally breaks down in two groups: structural and architectural. Traditional standing seam metal roofs, commonly seen in commercial applications such as fast food restaurants, are examples of structural panels.
Architectural panels, which can mimic the look of tile, shakes, shingles or slate when installed, have increased the use of metal roofing in the residential market.
Several new types of seaming methods, styles and colors have been developed to offer homeowners a wide range of prices as well as aesthetic choices. There are many styles and colors available that blend in with existing shingle colors. However, local building codes and neighborhood bylaws should be addressed when considering metal roofing.
Metal roofing offers the following advantages:
Because it does not warp, split or crack and is impervious to mildew, rot, termites and pests, a metal roofing system is virtually maintenance free over the life of the roof.
Properly installed metal roofing systems will withstand inclement weather, including high winds, hail, snow and rain better than any other roofing material. Metal easily sheds snow and ice and does not absorb water that causes cracking and rotting in the freeze-thaw cycling in other materials. In testing, metal systems have withstood winds up to 200 mph, and have historically survived hurricanes and wind storms when other materials have failed.
Most metal roofing systems carry fire ratings that can reduce a homeowner’s overall insurance rates.
Its light weight often allows metal roofing to be installed over the top of existing roofs, bringing significant savings in time and labor in addition to eliminating the growing disposal problem associated with shingles.
Although the initial cost of metal roof systems may be higher than shingles, the cost/benefit ratio over the life of the roof is superior to shake, slate, or tiles. When the finish eventually deteriorates over many years, it’s often possible to repaint the roof instead of replacing the panels.
