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 shingle, tile, and wood shake. It is more stable and can withstand strong winds, wind -driven rain, extreme temperatures, fire, mold, and termites. A properly fitted metal roof should last the life of the home. The most important thing for a qualified roof fitting is a qualified roof fitting company, see http://www.londonecometal.com/ .
Compare thick aluminum pans to iron or cast iron pans of even close to comparable thickness and see for yourself. Thin steel pans form “hot patches” that are due to a lack of heat conduction. Aluminum roofs are around one-third the weight of steel roofs and are quite devastating.
It also does not retain paint. And the screws / nails should be stainless or aluminum to minimize galvanic corrosion of the aluminum where the metals are in different contact or close to each other. High-quality metal roofs have many layers of coating that work effectively to prevent corrosion of steel roofs as long as they are not heavily damaged or the cuts are not sealed.
Here are some of the features that homeowners should consider while shopping for steel and aluminum roofs.
What You Need to Know About Roof Roofs
Steel roofs are strong, safe, and ecologically beneficial because of their 100 percent recyclable  that nature. Steel roofing panels, which are common in older structures in Europe, are becoming more popular in North America.
Many steel roofing materials have a 40- to 50-year "lifetime" guarantee and often exceed half a century. Consider the following factors when looking at steel roofs:
- durability / measure – The lower the number, the more durable the metal. Roof panels vary in thickness from 22 gauge (the thickest) to 29 gauge (the thinnest).
- Solar reflection improves energy efficiency because it allows less heat to enter the dwelling.
- Aesthetics – Steel can be colored or customized to match the decor.
- Heat Running – A Galvalume finish (also known as Mill Coating) offers extreme protection against UV radiation.
Steel roofs offer a variety of advantages, including:
- Cost – Although initial installation costs can be greater than other types of the roof, the steel lasts longer and reduces energy costs by reflecting radiant heat away from the home.
- Steel can be customized to appear like wood, tile, slate, or shingles.
- Steel roofs are lightweight and can be built quickly, even on an existing roof.
- Resistant to moss and fungus – Iron is completely impervious to algae and fungus, which can reduce lifelong asphalt or wood shingle.
- Animal -proof – Steel is inhos harmful to termites and other species that may seek sanctuary under roofs, such as raccoon and rats.
- Steel roofs are relatively expensive and can rust in the long run with contact with moisture.
Steel roofs are marked Class-A
Steel, on the other hand, is not good in sea water. Moisture from the ocean oxidizes the iron component of iron over time, resulting in ferric oxide, often known as rust. Manufacturers combat rust by coating roofing panels with zinc or Galvalume, an aluminum-zinc alloy, to make a protective barrier.
Aluminum Roof Fundamentals
Aluminum, like steel, is known for durability, longevity, ease of installation, energy efficiency, and resistance to fire and pests. It is also lighter and more adaptable than steel. Aluminum is naturally resistant to oxidation and corrosion, making it ideal for shore settings. Special coatings can provide even greater protection.
Because aluminum is an excellent conductor of heat, it is often used as a heat sink . That is, it absorbs and loses heat at a rapid rate.
The finest heatsinks are constructed of 70% silver and 30% copper, but are so expensive and scarce that they are not worth discussing.
Aluminum is more resistant to corrosion than steel. Aluminum is lighter than steel but softer, so it will ' t put more strain on the construction of your home but will not withstand the pounding of a violent hailstorm as well as steel. Aluminum “also holds heat” better than steel; it heats up quickly during the day and does not cool down quickly at night. This (along with its weight) is why it is widely used for cooking tools such as pans. Iron is the polar opposite in all these properties; it is stronger at a given thickness but heavier, and even stainless steel (which is relatively expensive) can rust. Either of these metals tends to have some liberal coats of very strong paint; for steel, it is critical that the paint layer does not penetrate.
Aluminum also has the following advantages:
- Malleability – Aluminum is softer than steel and can be constructed in complex forms, giving the appearance of shingle shingles into a longer, more protective product .
- Fire resistance – Aluminum alone is not Class -A certified, but this may include the addition of a fire barrier.
Heat treatment – Aluminum cools quickly after it is heated.
- Aluminum roofs are very lightweight and strong winds can easily lower their durability.
Steel and aluminum are both excellent materials for residential roofing. Before choosing, homeowners should check the properties of both the metals as well as the location of their property.
