Previously, metal sheet roofing was mainly used for agricultural, commercial and industrial purposes. Barns and industrial buildings with such a roof were commonplace at the time. Although it was rarely used for residential purposes, the popularity of metal sheet roofing gradually decreased. The material was prone to rust and corrosion. Over the years, these products have evolved and now metal roofing is available in a variety of styles, models and types. These new versions are not only rust resistant, but also aesthetically pleasing.

What is corrugated sheet metal roofing?

Most of us are familiar with corrugated cardboard, which is used to make cardboard boxes, and shipping containers. Made of thin paper, corrugated cardboard is stiffer and stronger than a stack of plain paper. This is due to the wavy pattern in which the papers are arranged. The same principle applies to corrugated metal sheets that are made in the shape of a wave, with alternating protrusions and grooves.

This model gives them extra strength, despite the fact that it is lightweight. Thus, corrugated metal sheets are stronger than conventional metal sheets.

Various metals and alloys are used for the manufacture of the roof. These include copper, aluminum, zinc alloy, tin (blackthorn), stainless steel, and galvanized sheet. Aluminum is generally preferred for residential spaces, as this metal is extremely lightweight. It is also durable and resistant to rust, even if there is no coating. Usually, the coating serves for a better look and a longer service life.

Corrugated stainless steel sheets have a “triple” coating that gives a natural matte gray finish. However, this type is very expensive. Copper roofing is easy to install and has a shiny sheen, but can be very expensive. Metal roofing can also be made of alloys that are strong and durable, but again, the cost of alloys is on the higher side.

Thanks to the latest technological advances, corrugated sheet metal roofing has a wide range of convenient functions. Modern versions are not only resistant to rust and other natural elements, but also correspond to the latest trends. Various types of coatings are used to give the product waterproofness, algae, rust and heat reflection. However, it is advisable to have a basic knowledge of the pros and cons before choosing a roofing material.

Advantages of corrugated roofing

– The most popular feature of corrugated sheet metal roofing is its durability. With proper installation, these roofing sheets can easily last from 25 to 50 years. Some manufacturers offer a 50-year warranty.

– These metal roofing sheets are treated and coated with chemicals to prevent the growth of algae and mold. They are also resistant to rotting and rust, as well as insects such as termites. Other useful properties include its non-combustible nature. This roofing material has a class of fire resistance class A, which is the highest indicator of fire resistance of the product.

– Those with heat-reflecting coatings benefit from reducing air conditioning costs. Tax breaks are also offered to those who install certain types of energy-efficient metal roofs.

– Metal roofing is ideal for people living in cool climates, as metal attracts heat and warms interiors. Some types also come with weather-resistant properties.

– Metal roofing is also lightweight and easy to install. This reduces the load on the roof structure and the building itself. Unlike asphalt shingles, each metal roofing sheet is large enough to cover more space, and this saves time.

– Maintenance is minimal in the case of metal roofing, which can also be easily cleaned. All you need to do is check once or twice a year.

– First of all, the roof of corrugated sheet metal is an environmentally friendly product that saves space in the landfill, because it lasts longer and is suitable for recycling.

Disadvantages of corrugated roofing

– This roofing material is expensive compared to other materials such as asphalt shingles. Another disadvantage is the high cost of installation. This is usually compensated by less maintenance or repair work. This requires experienced installers with technical skills and experience.

– The corrugated sheet metal roof is prone to dents. Dents can be caused by any heavy object that can fall on the roof. Even hail can lead to such dents.

Users often complain about the noise created by rain falling on these metal sheets. This can be reduced by installing insulation under the roofing material.

– Despite its long service life, this roofing material can scratch, peel off and fade over time. In some cases, metal roofing sheets may bend due to temperature fluctuations.

Although various metals and alloys are used to make corrugated sheet metal roofing, the most popular among them are aluminum, stainless steel, galvanized steel and copper. Galvanized steel roofing is cheaper than other types, but it can develop rust if the coating wears off.

It can also be damaged due to salt exposure in coastal areas. Aluminum roofing is good for those who live in coastal areas, but is more prone to dents. Copper roofing is more expensive than steel and aluminum.

When installed correctly, corrugated metal sheet is an ideal material for roofing. It is lightweight and durable and meets the criteria of most builders and home owners. However, it is always advisable to learn more about the material before investing. To do this, you need to seek advice from contractors or manufacturers of roofing materials.
