The Use of Metal in Residential Roofing Materials
There are many types of residential roofing materials. One that is a very popular choice is metal. Metal roofs are known to last a long time, sometimes over 50 years, and are able to withstand many different types of elements from rain to wind and even snow and ice.
The materials used for metal roofs range widely from steel to copper, tin and aluminum. Though metal roofs were used frequently in the past, they are now coming back into style. They are extremely expensive to build and come in a variety of conditions.
Two popular types are galvanized or galvalume. Galvanized is the most widely used of the two while galvalume is frequently used in the south where hurricanes are a common occurrence.
Metal roofs are durable because of their fire retardant properties. They are also almost maintenance free and energy efficient. This is because metal reflects heat, therefore blocking its transfer into the attic of the home. Coatings with high reflective values to steel sheeting will actually increase the thermal efficiency of homes located in areas where the temperatures are often high.
Steel roofs offer other benefits when used as residential roofing materials. They offer 60 to 65 percent recyclable material, thus making them an environmentally friendly choice. They also weigh very little which means this type of roof can be installed over an existing one. This eliminates the need to dispose of access material that would otherwise exist if it was first necessary to remove a pre-existing roof.
Standing-seam roofing is the most popular choice for residential roofing materials today. The term standing-seam refers to upturned edge of one metal panel that connects it to other adjacent sections of the roof.
This creates vertical lines that are distinctive in nature and makes it a trendy choice with a historical look. Metal roofs can also be constructed to resemble wood shakes, clay tiles, shingles and Victorian metal tiles.
Here, aluminum or coated steel may be formed into individual shingles or tiles or into modular panels that mimic them. Because of this, the installation of some types of metal roofing can be quite an intricate process and is best accomplished by someone who is a professional roofer.
Also, the initial cost of a metal roof that is premium in value is higher than most other residential roofing materials. Still, when you take the low maintenance and longevity factors into consideration, it may be well worth the investment.
