Advantages And Disadvantages Of Metal Roofing

Whether you're putting a roof on a new house or an existing roof that needs to be completely redone, there are many materials available. However, no matter what roof style metal roofs you use, they may be an attractive option due to their long service life, minimal maintenance, and high energy efficiency. You can choose from tin, zinc, aluminum, copper, or galvanized steel.

1.The advantages of metal roofing

Stone covered metal roof have many advantages, including:

A long life

Metal roofs can last 40-70 years, depending on the material. The life expectancy of traditional asphalt roofing materials is about 12 to 20 years.

Durability

Some metal roofs can withstand gusts of up to 140 miles per hour, will not corrode or break, and maybe impact-resistant (depending on the metal of your choice). In addition, metal roofs do not require the regular, expensive maintenance that other roofing materials often require. However, they should be checked periodically to ensure that no repairs are required.

Security

Metal roofs do not spark and burn in the event of a wildfire or lightning strike.

Energy efficiency

Metal roofs reflect radiant heat from the sun, reducing cooling costs by 10-25%.

Environmental protection

Not only are metal roofs 25 to 95 percent recyclable (depending on the material used), they are also 100 percent recyclable at the end of their useful life. In contrast, most ribbon-torn waste ends up as part of a construction-related waste stream - up to 20 billion pounds a year.

2.Disadvantages of metal roofs

Despite its many advantages, metal roofs also have some potential disadvantages.

Affordability

Metal roofs can cost twice or three times as much as other roofing materials. Although metal roofs last longer, it only makes sense to invest in them if you plan to spend enough time in your home to be cost-effective.

Noisy

Metal roofs can be noisy, especially during heavy rain or hail. Adding more insulation to the installation process can often solve this problem, but this can add to the cost.

Expansion and contraction

The metal roofing material used as a connection between large panels tends to expand and contract. If fasteners that allow the metal to "breathe" are not properly installed, the panel may become loose.

The color match is inconsistent

If repairs or additions are needed a few years from now, it may be difficult to find materials that match the existing metal.

Performance

If it accumulates anywhere on the roof due to poor installation or maintenance, it can eventually cause serious damage. Low-grade metals may also be thinner and less durable. During hail or installation, some metals rust in certain climates or sag more easily than others.
