A metal roof is basically a roofing system composed of metal sheets or tiles characterized by their high tensile strength, durability and resistance to fire. It is essentially part of the building envelope, which is generally comprised of claddings, membrane roofs, ridge vents and gables.
Metal roofing is available in a wide variety of colors, textures, and designs. Metal roofing is preferred to wood, clay, or slate because of its low maintenance costs, aesthetic qualities, and durability.
Generally, metal roofing systems are more stable than the traditional one because it consists of heavier materials Metal roofing. These include steel for the frame and aluminum for the sheet metal. The installation requires advanced knowledge and skill due to the intricate construction procedure, which is time consuming. Moreover, there are different types of metal roofing systems such as roll-to-roll, pitch-and-fit, modular and prefabricated steel construction.
Compared to other roofing systems, metal roofing is relatively less expensive with respect to energy consumption and maintenance. However, because of its heavy weight, it requires specialized transportation that involves expensive fuel. Furthermore, it is susceptible to mechanical damage during strong storms that may lead to its premature deterioration and failure. Thus, it needs periodic maintenance and repairs.
In addition, the installation process for metal roofing is more complex and difficult than the traditional type, which makes it more expensive. Metal roofing panels are exposed to more sun, so you need to have them installed in an area that is least exposed to direct sunlight.
There are different types of metal panels such as cold rolled, hot rolled and pressure-treated cold rolled. For the hot-rolled panels, the process includes welding and coating while the cold-rolled ones include quenching and annealing.
Moreover, this type of roofing material is not flexible as it has sharp edges that can be damaged easily. Also, rusts and corrosion are some of its major disadvantages. The UV rays from the sun can lead to the damage of your metal panels. This is why it is important to regularly check and treat the metal roofing material for signs of degradation.
Despite the disadvantages, metal roofs offer a lot of advantages when compared to the traditional types of roofs like ceramic tiles, clay tiles, slate, and wood shakes. They are durable and strong. And aside from its strength and durability, it is also environment friendly.
Thus, they are considered one of the most viable options when it comes to home improvement. But before installing metal roofing materials, you must consider their pros and cons. With this, you will be able to decide whether to install it or not.
