Steel Roofs

Steel roofs currently occupy 10% of the market share. However, steel roofs are gaining in popularity, and more clients are choosing to go with this type of roof. As a contractor, your experience has been installing asphalt roofs. However, to keep up with the trend, you need to be knowledgeable about steel roofs.

Materials

Steel roofs can be constructed out of a variety of materials. Traditionally, steel roofs have been constructed from galvanized steel, and it is still used. Corrugated galvanized steel consists of a combination of wrought iron and steel with a zinc coating.

Another popular type of steel roof is one made of standing seam metal. This corrugated product comes in a rolled form. It gets its name from the seams that are created by roofing equipment used to attach each section of steel. When choosing this type of steel roofing or any other type, it’s important to know that the higher the number the lower the grade of steel that you have chosen.

Steel roof titles look similar to traditional shingles once they have been installed. This type of steel roof material usually comes in panels. These panels are interconnected and when they are attached to each other give the illusion of a shingled roof.

Coatings

Coatings are used on steel roofing products to protect against solar radiation, rust, corrosion and to provide waterproofing. Ceramic coatings are used to deflect heat. At first, ceramic coatings deflect 75% to 85% of solar radiation. However, that figure drops by 30% over time. Another drawback of coatings, which are usually made of acrylic or polyester paints, is that they require recoating as part of their maintenance.
