Metal roofs are becoming the material of choice for many homeowners, replacing asphalt shingles. Metal roofs offer aesthetic and functional advantages over other materials, including options to design durability and versatility. These roofs are available in a number of different styles and materials, and can easily last for decades with little maintenance.
Materials
The steel is the most common material used on metal roofs. It is also one of the most affordable. Aluminum roofs are much more expensive, but may also be more durable in some applications. Copper is the most expensive metal as roofing option, and is mainly chosen for its intense color and visual appeal. The tin roofs can be used in offices as barns and sheds. This material is more durable, less expensive and more used to create metal roofs.
Forms
Metal roofs can be used both in steep structures and low-slope roofs. Smooth or embossed panels are installed using a locking technique that creates a standing seam design. Some metal roofing tiles are formed, shakes or tile to mimic the look of wood or clay roofing. The metal can be fixed with wooden nails or other patterns to give an authentic look.
Benefits
While metal roofs usually offer many benefits to homeowners, each type of metal roofing material has its own advantages. Steel is one of the most durable types of roofs, and is resistant to dents caused by wind, hail and strong impact. Aluminum is highly resistant to oxidation and corrosion, and is often the best choice for ceilings in coastal areas. Copper, tin and aluminum are usually left unfinished and require little maintenance to maintain their appearance.
Disadvantages
Each of these materials also has some disadvantages that must be considered. The steel can rust or corrode, and should not be used near salt water or very humid areas. Aluminum is a relatively soft metal and tends to dent easily. Copper interacts with atmospheric oxygen to form a greenish coating known as “patina”. While some buyers who like this effect, others consider it a disadvantage. The steel must be repainted every few years to maintain their appearance.
Considerations
When choosing between different types of metal roofs, note the desired look and style of your home. The visual appeal is particularly important when the housing parts are visible from inside the house or from the outside. It also helps to consider the cost of housing compared with its useful life and maintenance requirements. Finally note the local climate, including levels of wind, rain and snow.
