Metal roofing

When people reckon of metal roofing they reckon of the corrugated “tin barn” look.  But using metal roofs has come a long way.  Today metal roofing includes a variety of styles and materials so that the roof has style and visual appeal, while still retaining durability, longevity, fire resistance and simple maintenance.

Metal roofs are made from a variety of metals.  These include the traditional aluminum and steel, as well as copper and a variety of alloys.  Modern metal roofs can be formed into shapes that imitate Spanish tiles, wood shakes, and even slate.  They can be given a variety of finishes such as granulated stone topcoats to complete a realistic imitation of nearly any other material.  

There are some negatives to a metal roof.  One consideration is the cost, with a typical square running from $150 to $600.  Another is the necessity of professional installation and maintenance, again adding to the overall cost of a metal roof.  But even with these negatives many people feel that metal roofs have benefits that make them worthwhile.  Speaking of cost, a properly installed and maintained metal roof can last as long as the house.  That means, over a typical home’s expected life, the cost of a metal roof is low compared to the cost of other roofing materials that might require replacement after 15 to 20 years.

Metal roofs are lightweight, fifty to one hundred fifty pounds per square compared to seven hundred fifty pounds per square foot for tile or 900 pounds per square foot for concrete tile.  Metal roofs can be installed right over existing roofs without installing additional support.  Metal roofs withstand high winds, snow slides off them, and they are resistant to mildew, insects and rot.

Pitch is another vital factor with roofs.  Many materials require a steep pitch to ensure water flows off the roof so that the roof won’t leak.  The pitch for a metal roof can be more shallow, with a typical recommended minimum being 3-in-12, which is three inches of height for every horizontal foot.  Consider the benefit of a less steep roof next time you have to climb onto it to clean the gutters, or retrieve a ball or Frisbee thrown there by a child.

Just as with other home projects that require a professional, the best way to find a metal roof contractor is through word of mouth.  Talk to friends and neighbors, or look for metal roofs around the neighborhood and question the home owners for the name of their contractor.  The Internet is a excellent source for pre-screened metal roofing contractors, as are architects who design homes with metal roofs.  The National Roofing Contractors Association can also help.  Their number is 1-800-USA-ROOF.

A cat on a hot tin roof may not be a excellent thing.  But if you want a long lasting roof for your home, consider that traditional wood and shingles are excellent, but metal is better.
