Although metal roofs may seem like a fairly new concept, they’ve actually been around since the 3rd century B.C. Copper roofs were commonly built to protect everything from homes to temples. They were made in the form shingles that were layered in order to keep rain out. Since then metal roofs have grown into one of the most popular types of material in America. They are a far cry from original tin roofs that early Americans used on their homes.
What are Metal Roofs Made Of?
The term ‘metal’ is a broad concept for the various types of materials used for making metal roofs. Various metals utilized in roof construction have led to the evolution of metal roofs over the last eight decades.
● Galvanized steel. One of the most common materials used in metal roof construction is galvanized steel that is corrugated and coated with a tough zinc finish.
● Stainless steel. Stainless steel has proven to be a better option than galvanized steel because it resists corrosion caused by heat and humidity.
● Copper. Speaking of resistance to corrosion, copper has rust-free properties that have made it a mainstay of roofing for eons.
● Metal blends. Depending on the application, there are times when combining different types of metal makes an ideal roof. In such cases, manufacturers may blend zinc and aluminum or steel and silicon.
The Manufacturing Process
Standing seam metal roofs are the most utilized type of residential roofing material in the industry. Standing seam roofs are produced by feeding coils into a roll-former. This machine converts raw metal into roofing panels of varying sizes. These panels can be up to 22-gauge in thickness and made of extremely tough steel.
Once the sheets are developed, they can be altered into specific panels depending on the type of roof a building requires. For instance, standing seam panels are often fitted with snap-locks and designed to be a certain dimension in order to perfect fit the roof design. Panels are generally made in widths of 12, 16, and 20”. The roll-former is controlled by a computer that decides the panels dimensions. it can cut them to precise measurements.
In addition to the panel itself, several accessories have to be made so that the roof installation can be completed according to industry standards. The accessories can include the following:
● Drip edges
● Rake/gable trim
● Valley pans
● Ridge caps
● Z-bar, sidewall, head wall, chimney, and skylight flashing
Once the sheets are produced, a hard coating is applied to the surface to ensure that the sheet is weatherproof and will last for well over five decades. The finished product is ready to install on the house.
