As promised, we bring to you part 2 of our series on the advantages and disadvantages of asphalt and metal roofing. In Part 2, we focus on metal roofing.
Advantages of Metal Roofing:
Long-lasting and weather-resistant
Metal is exceptionally resistant to weather, and some copper and zinc metal roofs in Europe have been reported to last for over a century. Generally, a metal roof can be expected to last for about 60 years; but if it is well-maintained, it can last for much longer. Many metal roof manufacturers usually give warranties of about 50 years. A metal roof prevents leaks and it is also wind-resistant and fire-proof. There are insurance companies which reduce premiums by up to 30 percent if one installs weather-resistant metal roofing.
Metal is extremely light, and an aluminum roof can weigh just a quarter of the weight of an asphalt roof. Steel is a bit heavier, but it is still lighter when compared to asphalt.
As a roofing material, metal is a very energy-efficient. It reflects heat, making the house remain cooler during summertime. In addition, metal roofs are often made using recyclable material.
Disadvantages of Metal Roofing:
Expansion and contraction
A metal roof may expand and contract considerably. This may interfere with its performance in the long run and make it less watertight. However this depends on the way it is installed. Hire a trusted professional like Rogers Builders to do the job and the work will be done properly and guaranteed.
Metal has long been used to build agricultural buildings like barns. It can therefore look bit industrial when used for residential houses
The biggest disadvantage of installing metal roof is cost. A metal roof costs, on average, three times more than an asphalt one. Other metals such as stainless steel, zinc and copper cost even much more.
Poor past record
Some time back, roofs made using corrugated metal corroded in less than ten years, particularly in places near the sea. This caused them to be perceived as not being durable. Nowadays however, metal roofs are made using special resins and alloys which means they are very resistant to corrosion, heat and heavy rain.
Some low quality products on the market
While high-grade metal roofs are widely available, there are also some low-quality metal roofs on the market. Building experts caution against using such products, particularly for people living close to the sea.
