Choosing between steel and aluminum for your new roof often boils down to a simple question: Where is your home? Metal roofs generally have many benefits over asphalt shingles, tiles, and wood shakes. They are more robust and can withstand strong winds, wind-driven rain, extreme temperatures, fires, mold and termites. A proper metal roof should last the life of the home. The most important thing for a proper ceiling installation is a worthy ceiling installation company, take a look at http://www.londonecometal.com/. Compare thick aluminum pans with steel or cast iron pans even close to similar thickness and see for yourself. Thin steel sinks develop “hot spots” due to a lack of thermal conductivity. Aluminum roofs weigh about one-third the weight of steel roofs and corrode relatively little. It also does not retain paint. Bolts/bolts shall be of stainless steel or aluminum to reduce the galvanic corrosion of aluminum where different metals come into contact or are close to each other. High-quality metal surfaces feature several layers of coatings that work effectively to prevent corrosion of steel surfaces as long as they are not severely damaged or the pieces are not sealed. Here are some of the qualities homeowners should consider while shopping for steel and aluminum ceilings. What you need to know about steel roofs Steel roofs are strong, safe and environmentally beneficial due to their 100 percent recyclable nature. Steel roofing sheets, common in older structures in Europe, are becoming more and more popular in North America. Many steel roofing materials come with “lifetime” warranties of 40 to 50 years and often last more than half a century. Consider the following factors while looking at steel surfaces: Durability / Gauge – The lower the number, the more durable the metal. The thickness of the roofing sheets varies from 22 gauge (thickest) to 29 gauge (thickest). Solar reflectivity improves energy efficiency because it allows less heat to enter the dwelling. Aesthetics – Steel can be colored or customized to match the decor. Thermal Conductivity – Galvalume coating (also known as mill coating) provides additional UV protection. Steel roofs offer a variety of benefits, including: Value – Although initial installation costs may be greater than those of other types of roofs, steel lasts longer and reduces energy expenditure by reflecting radiant heat away from the home. Steel can be customized to appear as wood, tiles, panels or wood panels. Steel roofs are lightweight and can be built quickly, even over existing roofs. Algae and Fungus Resist – Steel is completely impenetrable to algae and fungus, which may shorten the life of your asphalt or shingle. Animal Resistant – Steel is inhospitable to termites and other species that may seek refuge under surfaces, such as raccoons and mice. Cons: Steel roofs are expensive and can rust in the long term when in contact with moisture. On the other hand, steel roofs have a first-class steel rating, which does not perform well in sea water. Moisture coming from the ocean oxidizes the iron component of steel over time, producing ferric oxide, often known as rust. Manufacturers combat rust by coating roofing sheets with zinc or Galvalume, an alloy of aluminum and zinc, to produce a protective barrier. Aluminum Roof Basics Aluminum, like steel, is renowned for its durability, longevity, ease of installation, energy efficiency, and resistance to fire and pests. It is also lighter and more adaptable than steel. Aluminum is inherently resistant to oxidation and corrosion, making it ideal for coastal locations. Special coatings may provide much greater protection. Since aluminum is a good conductor of heat, it is often used as a heat sink. That is, it absorbs heat and loses it at a rapid pace. The best heatsinks are made of 70% silver and 30% copper, but they are so expensive and rare that they are not worth discussing. Aluminum is more corrosion resistant than steel. Aluminum is lighter than steel but softer, so it puts less stress on your home’s construction but won’t withstand the pounding of a violent hailstorm as well as steel. Also, aluminum “retains heat” better than steel; It heats up quickly in the day and doesn’t cool down as quickly at night. This (in addition to its weight) is the reason why it is so widely used for cookware such as frying pans. Steel is the polar opposite of all of these properties. It is stronger at a certain thickness but heavier, and even stainless steel (which is very expensive) may rust. Either of these two minerals often have a few liberal coats with a very strong coating; For steel, it is critical not to puncture the coating layer. Aluminum also has the following advantages: Malleability – Aluminum is more flexible than steel and can be built into complex shapes, giving the appearance of vibrating shingles in a longer-lasting and more protective product. Fire Resistant – Aluminum alone is not Class A approved, but may be with the addition of a fire retardant. Thermal conductivity – aluminum cools quickly after being heated. Aluminum roofs are light in weight and strong winds can easily reduce their durability. Both steel and aluminum are good materials for residential roofs. Before choosing, homeowners should evaluate the properties of both minerals as well as the location of their property.
