Whether you are building a new house or renovating your present one, the choice of roofing material is an important decision to make. If you are looking for sustainable and aesthetic roofing then steel is one of the best choices. While asphalt continues to be a popular choice, steel is becoming increasingly popular as it is cost effective and environment friendly. Let’s look at the steel roofing pros & cons.
Steel roofing offers contemporary designs and is available in a plethora of colors. It’s mainly three types i.e. galvanized, galvalume and weathering steel. Galvanized steel comprises a layer of protective zinc coating that prevents rusting. Galvalume steel consists of a coating that has 55% aluminum, 43.4% zinc and 1.6% silicon. This coating makes the steel highly resistant to corrosion. Weathering steel is a strong alloy steel that provides an increased resistance to rusting as compared to other carbon steels.
Advantages and disadvantages of steel roofing
Strong and Durable
Steel roofing has the ability to withstand harsh weather conditions. It is preferred in regions having snow or hail because of its strength and durability.
After installing a steel roof, you do not have to worry about it for decades as it does not crack or warp in humidity, sunlight, or weather extremes.
Steel is relatively cheaper than other roofing materials and because of this it has been a primary choice for both residential and commercial projects. Also, steel roofs are more reflective as compared to other roofing materials. This helps in saving money as it keeps the heating and cooling costs low. Steel roofing keeps the house cool in summer by reflecting sunlight whereas it keeps the house warm in winters by reflecting heat from below the roof to the inside of the building.
Steel is available in many contemporary styles and colors. Also, a steel roof can be made to look like any other roof. This is done with the help of paints that are used to match the natural patina of materials such as wood, copper, tiles, clay, or shingle.
Steel roofs generally weigh less than one pound per square foot. As your house gets older it becomes weak as the structural lumber cracks and the foundations move. Having light weight steel roof system helps in increasing the life of your house and also in providing integrity.
Studies reveal that the North American landfills comprise more than 20 billion tons of asphalt shingles. These shingles will take around 400 years to break down. Therefore, steel roofs should be preferred over asphalt shingles as they can be recycled and therefore put less strain on the environment. Steel roofs can be entirely recycled making them an excellent environment friendly option.
The slick surface of steel and other metals makes snow and ice more likely to slide down the roof all of a sudden. This can cause serious injuries to people and may damage the objects below. In order to prevent this from happening, home owners should use snow or ice guards that hold the snow thereby allowing it to melt slowly.
Denting is another common problem with steel and other metal roofs. Hailstones and snow may sometimes cause denting and chipping in the roof. Therefore, you should carefully check the warranty against denting before investing in a metallic roof.
