WHY STEEL ROOFS?

Many homeowners concerned with aesthetic appeal are often positively impressed with the wide variety of contemporary styles, profiles, and vibrant colors available in modern steel roofing. Other benefits that help make steel roofs stand out among other roofing products, include low life-cycle cost, superior energy efficiency, and sustainability. For anyone who wants their roof to be an asset for years to come, rather than it being a constant source of problems, steel roofing can be a wise choice.

STEEL IS EXCEPTIONALLY STRONG AND DURABLE

Steel is one of the strongest, most durable building materials, which is why it is so widely used in commercial and industrial construction. Your home can benefit from superior durability of steel in several different ways; The inherent properties of steel make it highly resistant to cracking, warping, curling or peeling — all of these are common problems associated with asphalt shingles.

Did you know? A steel roof will not be susceptible to rot, decay, discoloration, mold growth or termite infestation. The superior durability of steel will free you from expensive and time consuming maintenance and repair issues that are a necessary part of owning most other types of roofing systems.

RESISTANT TO SEVERE WEATHER

Steel is famous all over the world for its ability to stand up to severe weather conditions, and for good reason. Steel is specifically designed to withstand harsh climates and extreme temperature fluctuations. With a steel roof, your house will be safe and secure against hail, snow, wind and fire, as steel roofs meet and exceed all local strict building codes.

Hail: Steel roofing is resistant to structural impact damage from hail. Steel roofs carry a Class 4 Hail Resistance rating, which means that they will not get punctured, chip or crack like slate or clay roofs do. Similarly, a steel roof will not be damaged by falling branches or any other objects or debris falling on it.

Ice and Snow: One of the most persistent roofing problems in northern climates is related to ice and snow. A steel roof can be your ultimate solution, because it sheds heavy ice and snow much better than other types of conventional roofing. Your steel roof can help prevent excessive snow build–up and eliminate the formation of ice dams as well as damage associated with them.

Wind: Your steel roof will never be damaged or blown off by strong wind. Steel roofs carry a Class 90 Wind Uplift rating and can withstand winds of up to 120 mph.

Fire: Steel is a non-combustible material and will not spread fire. Steel roofs carry the highest (Class A) Fire Resistance rating. Your steel roof will not be susceptible to windblown sparks, which are a common issue if areas with frequent wildfires.

LONG AND MAINTENANCE FREE SERVICE LIFE

Long service life is one of the best benefits of metal roofing, and one of the main reasons for its growing popularity among homeowners. A properly configured and installed steel roof can last at least fifty years, which means that most likely it will be the last roof you will need to install on your house.

What many homeowners love is that this long service life is also maintenance free. At most, you can periodically wash your steel roof to remove any debris. A steel roof’s maintenance – free service life provides a huge relief, as most roofing systems require a continuous investment of money and time for maintenance and repair.

The secret of steel’s long and maintenance – free service life is in the way steel roofing systems are manufactured. Before being painted, the base steel is either zinc-coated (galvanized steel), or is 55% aluminum – zinc alloy coated (galvalume steel), which prevents rust and corrosion. Moreover, steel roofing pre-finish and paint systems go through rigorous testing and are approved for exterior applications in all types of climates, successfully meeting the standards for weathering, fading, hardening, and chalking.

ABUNDANCE OF STYLES AND COLORS

Thanks to cutting-edge technological advancements in the steel industry, modern steel roofing offers a multitude of styles and color choices that will satisfy any aesthetic preferences. For homeowners who want the roof to enhance the contemporary style of their house, profiles that are distinct to steel roofing, such as standing seam, vertical rib or corrugated, are a perfect match. people looking for a more traditional look, can find a wide variety of styles in stone coated steel roofing profiles. Stone coated steel roofs are designed to replicate the looks of other roofing materials such as traditional composition shingles, cedar shake, clay tile, or slate, but without the many structural, maintenance and cost issues associated with many of the above roofing options.

Many prominent manufacturers also carry a wide array of standard and premium paint coatings for steel roofs include modified polyester, fluorocarbon (Kynar) and PVC (plastisol) coatings. For the longest service life, it is important to consult your roofing contractor and choose the right coating that will be the best match for your home’s particular architecture and local climate. Paint systems are typically guaranteed to last for 25 years. It is actually possible to repaint your steel roof to ensure many more decades of service.

LOW LIFE CYCLE COST

One of the greatest benefits of steel roofing is its low life – cycle cost. While an initial investment into a steel roof is higher than into an asphalt shingles roof or another conventional roofing material, few homeowners realize that over their life-cycle these cheaper roofs will actually end up costing more than a steel roof. Consider the fact that while you will pay for your steel roof only once and will never have to re-roof again, you will need to replace your asphalt shingles roof every 10-20 years. – This means you will be paying for a new asphalt shingles roof 2-4 times over the same period of time that you could have installed just one steel roof built to last. Also, tack on to the bill frequent maintenance and repairs required by most conventional roofing systems, and the total life-cycle cost of a steel roof will actually be less than that of an asphalt shingle roof.

ENERGY – EFFICIENT

A steel roof can help you realize even greater savings because of its energy-efficient properties. Steel roofs have reflective coatings, and are therefore considered “cool roofs“, reflecting sun’s UV rays back into the atmosphere. A highly reflective painted or granular-coated steel roof can actually re-emit up to 90% of absorbed solar radiation. This keeps the inside of your home cooler during hot summer months. This is an especially valuable feature for homes located in regions where it is hot and sunny year round. A steel roof can save you as much as 40% annually on your energy bills and enable you to live a life less dependent on polluting energy resources.

HELPS THE ENVIRONMENT

Homeowners that care about the environment and are looking for green construction materials, will be most satisfied with a steel roof. By far, steel is the real “green” choice in the residential construction industry, helping reduce pollution in a number of ways. First, steel is the most recyclable building material in the world. Consequently, your steel roof will contain between 25-95% of recycled steel content, depending on the manufacturer. Unlike other roofing products such as asphalt shingles, manufacturing of steel is not dependent on the oil industry, which means that by installing a steel roof you are contributing to lessening our nation’s dependence on oil.

Steel’s reflective properties help mitigate the heat island effect in urban areas, lowering temperatures by as much as 12 degrees and helping keep the air free of smog and pollution. Lastly, because steel roofs are lightweight, you will most likely be able to install a steel roof right over your old roof. This means that your old roof will not end up in the landfill, and will not contribute to the rapidly growing landfill waste problem in our country.

INCREASES REAL ESTATE VALUE & IMPROVES CURB APPEAL

You can feel good about investing into a steel roof, because unlike most conventional roofing systems, it will actually increase the value of your home. In case you ever decide to sell your house, a steel roof will be an attractive selling point: buyers will give preference to a roof they know is long – lasting, durable, energy efficient and maintenance – free. Independent studies confirm that a steel roof can increase the resale value of a home anywhere from 1-6% depending on the geographic location.

MISCONCEPTIONS AND MYTHS

Some homeowners are cautious about installing a steel roof over their home because of some common misconceptions. One is that steel roofing is very noisy, especially when it rains. In reality, this is not the case. Modern steel roofing is typically installed over plywood decking and felt or an already existing roof. Consequently, any noise from rain, falling branches or any other objects is muted out by this layer of insulation, making the level of noise from a steel roof the same as you would hear with any other conventional roofing material. Moreover, as with traditional roofing options, insulating your attic will lead to additional noise reduction. Another misconception is that a steel roof will attract lighting. Nothing can be further from the truth, as a steel roof does not attract lightning any more than other types of roofs.
