Brief History of Tin Roofs

While today, metal roofs are often referred to as “tin roofs”, the reality is that no roofing product has ever been made of pure tin. In Europe metal roofs have been around for centuries, originating in ancient Rome, and were made out of copper, lead, and zinc. Metal roofing material was produced by heating and hand hammering the metal to a thin sheet. In the 17th century, tin was first used in Bohemia as a coating for rolled steel to prevent rust.

Just before 1800s, “tin” plates, or shingles began to be imported into the US from Wales, where, tin was mined. Since initially tin shingles were expensive, and imported, they were not used in residential construction. However, after the Civil War, tin roofs became more widely used on homes when tin became available as shingles that could be installed with nails.

Tin’s popularity continued to grow due to declining prices, which resulted from replacing pure tin coatings with 65:35 lead to tin alloys. This newly created dull finish became known as “terne” plate. Tin roofs were highly esteemed for their durability in inclement weather, fire resistance, and longevity.

Metals Used in Modern Roofing

Today, home and business owners can enjoy a wide variety of options when it comes to choosing a type of metal they would like to install on their roof. Tin is still available as a coating (combined with lead) on one of several soft metal options, such as steel. One of the most popular and economical metals is galvanized (G-90) steel, made of alloyed steel with a protective coating of zinc to prevent corrosion. A step up from steel, is aluminum, which naturally resists corrosion and tends to reflect solar radiant heat better than steel. Homeowners who want to the most durable and long lasting protection for their roof, can choose to install a copper, or zinc roof. Both are premium metals that cost significantly more than others, but for the price, they offer great curb appeal, superior durability, and can easily last well over 100 years.

Advantages

Versatile and Attractive

Taking a look at various profiles of modern metal roofs, it becomes clear that there is nothing outdated about them. In fact, contemporary metal roofs are ultra-modern, stylish and appealing. Discerning buyers will find a wide variety of designs, colors, and textures that will compliment any type of architecture. Also, metal roofing can be manufactured in traditional vertical/standing seam profiles, or can be made to resemble shingles, cedar shakes, slate, or clay tiles.

Durable and Maintenance Free

Metal roofing systems are highly valued for their durability. They are resistant to cracking, shrinking, warping, curling, splitting, flaking, peeling, breaking, and being damaged by termites. A metal roof provides superior protection in all types of climates, and is most resistant to freezing and thawing cycles, inclement weather, and natural disasters. It will keep your property safe from fire, hail, wind, heavy rains, snow, and iced dams.

This exceptional durability lends itself to a long, maintenance-free service life of at least 40-50 years. Given that your new metal roof is installed properly to begin with, you will not need to spend any extra money, time and energy on roof maintenance, and costly repairs that are common with asphalt shingle roofs.

Energy and Cost Efficient

While a metal roof initially costs more than other types of roofing systems, it is a highly cost-effective investment. Metal roof’s reflective properties allow home and building owners to save up to 40% in annual energy costs, depending on geographical location. A metal roof increases the resale value of a residential property, adding about $1.45 per square foot to a home’s overall value. Moreover, recognizing metal roof’s superior durability, many insurance companies give discounts of up to 35 % to homes with metal roofs.

Green

For people looking for a “green” roofing material, metal is one of the most environmentally – friendly options. Metal roofs not only add to the home’s overall energy efficiency during their life time, they can also be recycled. Residential metal roofing systems are made from at least 30-60% recycled material. Moreover, being lightweight, metal shingle roofs can often be installed over an existing roof, omitting the need to tear-off and send the old roof as waste to a landfill.

Disadvantages of Metal Roofs

In comparison to other roofing materials, there are relatively few drawbacks to metal roofs. One of the main disadvantages of metal roofs is their relatively high upfront cost. For people who are not planning to stay in their home for decades, installing a metal roof may not be the most economical option, as they will not realize a quick return on their investment. Another drawback is that dark colors will tend to fade over time, so it is better go for lighter colors, which will not have this issue. Additionally, metal roofs tend to expand and contract more than other roofing materials during the thermal cycle. However, properly installed metal roofs have built-in design features to counter this issue. Lastly, it is critical to take extra care when walking on a wet metal roof, as it will get very slippery.
