Remodeling is not that easy of a task; there are many things to consider as every segment plays a crucial role, and one of such is the roof. There are various roofing options like metal, wood, etc. In this blog, we are dealing with metal. Let’s have a look at the most common kinds of metal roofing available, how long does a metal roof last, and the associated pros.

How long would a metal roof last In general?

The life expectancy of a metal roof depends on the type used and other factors. Let’s first discuss the types.

  • Steel Roof – generally lasts for about 40 years in total.
  • Copper roof – has a lifetime of 50 to 100 years.
  • Aluminum – gives an average of 50 years.
  • Tin Roof – same as above, 50 years.
  • Zinc Roof – 60 t 100 years on the whole.

Factors Affecting the Life Expectancy of a Metal Roof

Now that you know how long each kind of metal roof last, you must know the factors that either increase or decrease their time.

Color of Your Roof
Yes, color does have an impact. Your metal roof will last long if you opt for light colors such as white, reflecting sunlight and heat. This, in turn, reduces the temperature inside the house or building, whichever it is.

Pitch Of the roof
Pitch, or more like the steepness of a roofing system, affects its timeline. A steep slope drains away water easily. At the same time, a low gradient flows off water slower. Resultantly, accumulated water increases wear and tear issues because the metal roof soaks it, reducing its life expectancy.

Moss is poison for the roof; it speeds up deterioration. Organic matter growth is not common on a metal roof which is why they last long; however, their presence cannot be completely ruled out.

They live in shady and moist areas on the roof. If trees surround your project, then it is susceptible to moss growth.

Maintenance of the metal roof is prime for its long life; therefore, many owners use metal as an advantage because they require low maintenance. However, that does not mean you do not examine it from time to time.

Metal Roof – Advantages

They have extensive benefits, including:

Metal roofs easily last up to 40-70 years. This depends on its material, and other factors stated above. If we compare metal roofs with traditional asphalt roofs, they only last 12-20 years.

With accurate installation, metal roofs may be able to sustain wind gusts that go up to 140 miles per hour. Even then, they will not rust or crack.

Metal roofs do not spark or ignite into flames at the time of a wildfire or lightning strike.

Energy efficient
They reflect UV rays from the sun and infrared light rays. Both contribute to roof surface damage. Using metals can result in a more or less 10-25% reduction in cooling costs.

Environmentally friendly

Metal roofing has about 25 to 95% recycled content. Whereas most shingle waste ends up in the waste stream.

Final Words

Metal roofs are expensive compared to other options. However, their long life makes up for the cost. If you want remodeling services, contact Qamar Constructions for help.
