Why Choose Metal Roofing Over Asphalt Shingles?

Have you ever imagined being in a home without a roof over your head? Impossible, right? That is how the ceiling is important in every construction. The roofing sheets give you the feel of being secured and safe. Whether you build a home or remodel the existing roof, roofing plays a vital role in every construction. The materials involved in the roofing will enhance the appearance of the house. However, with the help of science and technology advancements, the construction industry has evolved immensely. Traditionally, people used slates and brick tiles for their roofs. Now with innovative technologies, brick tiles have been replaced with roofing sheets made of metal and polycarbonate. Asphalt shingles are one of the roof covering sheets used commonly in North America in early 1903. It is still in practice and a suitable sheet for every establishment. Hence, in this post, let us see the reasons why to choose metal roofing over asphalt shingles.


Metal roofing sheets require less maintenance than asphalt shingles. The asphalt shingles are inexpensive but require more maintenance. These shingles are formed of organic or inorganic materials coated with asphalt and ceramic-coated opaque mineral granules. The disadvantage of using shingles is they may disintegrate into pieces if anything falls or slips on them. But in metal roofing, the core materials are copper, steel, and zinc. Hence, these metals are known for their strength and stability. Therefore have a consultation with the roofing expert to determine the angle and slope of the roofing sheet for better maintenance.


The durability of any material depends upon exposure and regular maintenance. Maintaining any substance with extra care will improve the lifespan eventually. The average lifespan of asphalt shingles is 40 to 50 years. These shingles tend to rip apart due to extreme weather conditions. Especially, wind, sun, and precipitation can wear the shingles much faster. On the other hand, a metal roof can last more than 50 years. As the core materials improve with technology, the newer roofing sheets may last up to 100 years. The metal sheets undergo various processes and treatments with several types of coating to protect them from extreme weather conditions. 


Asphalt shingles cost only one-third of that metal roofing costs. It is commonly used in North America and costs approximately Rs.60 to Rs.140 per square feet. But metal sheets are very expensive and approximately Rs.100 to Rs.160 per square feet. But, metal sheets are worth their price more than the asphalt shingles.

Heat conduction:

The heat conductivity in asphalt shingles is higher than the metal roofing. Shingles reflect the heat into the building and create a heat island effect inside the building. On the other hand, the heat conduction in metal sheets is low and significantly reduces the heat island effect.

However, for a stable roofing sheet, you need a sturdy frame to fix the sheet. C purlin manufacturers provide the best quality framework for the installation of sheets.
