Is a metal roof the answer to all your roof problems? Not always – there are pros and cons of residential metal roofing. Most people think a metal roof is a permanent solution, but that is just not true.
With metal as a material, there are many different design possibilities for roofing. Metal roofs are becoming more and more popular, not only on factory buildings or churches, but also more and more on residential buildings. The most unusual roof shapes can be clad with metal. In addition to aesthetics, metal roofs meet the highest requirements in terms of durability, strength and stability. Metal roofs are virtually maintenance-free when professionally installed and are therefore very cost-effective in the long term. Metal roofs are also more durable compared to asphalt or wood roofs. Metals are available in various colors and shapes, that are available in all varieties of appearances.
Copper has the highest elongation at break of all construction metals, ie it can be stretched and deformed the most before the material breaks. It is therefore very well suited for complicated connections, where strong deformations are required. When assembled, copper is glossy red metallic. As a result of the weather, a patina decking layer rapidly forms, so that the sloping roof shows a light green to blue-green hue. For vertical surfaces is not to be expected with a green color but with a deep brown to anthracite gray color. Copper edges, folds and bends. Among other things, the metal can be artfully processed.
The material used in a zinc roof is titanium zinc. This alloy contains at least 99.995% fine zinc. This gives the material an improved creep resistance, the thermal expansion is very low and it can be processed well. Due to weather conditions, a gray-blue protective layer is formed. The processing of titanium zinc is easy. For example, it can be adapted to all types of construction by means of edges or folds.
Stainless steel roof
The surfaces of stainless steel roofs can be bright rolled, frosted or tinned. The tin surface coated stainless steel can be processed in conventional plumbing technology. The material also has a low coefficient of expansion, a low weight and resistance to corrosion.
Aluminum roofs have been tried and tested for decades in old and new buildings. Cold-rolled aluminum forms a resistant protective layer with the oxygen in the air. This becomes harder over the years and renews itself when mechanically removed. Often aluminum roofs have a color coating, so you can choose the most suitable among many color options. However, these coating systems also offer protection against the environmental influences. Farm aluminum is very resistant to corrosion since it is created with aluminum sheets, which have different cross sections and profiles. Aluminum is very light, so the requirements for statics are correspondingly lower.
Advantages of a metal roof
A big advantage of the metal roof is its stability. Roofs made of metal have a high strength and are durable. When using a plastic coating, the roof is protected from thermal expansion. This is especially important for zinc roofs. Metal roofs also have excellent insulating properties, deflecting the harsh rays of the sun in the summer, and melting snow in the winter. The 26 gauge metal is can be installed directly on top of the old roof or decking with waterproofing, with one inch airspace allowance for maximum insulation.
Metal roofs are very low maintenance compared to roofs with bricks or other variants such as thatched roofs. In addition, the roofs are 100% recyclable, depending on the material, such as the titanium zinc. This makes them extremely environmentally friendly. In contrast to roofs made of wood or roofing with clay tiles, metal roofs are less susceptible to weathering. This makes them particularly suitable here in Northwest Arkansas where we have extreme weather changes and high temperature fluctuations. Unlike a brick-roofed roof, individual parts can not fly away in a storm. Roofs made of metal represent an ideal lightning protection. This is similar height as in a car. The condition is that the roof is grounded, usually via a metallic gutter. The property has a positive effect that the material can be used to create a variety of roof shapes. Depending on the architectural design, self-supporting and non-self-supporting roof structures are possible.
Disadvantages of metal roofs
One of the disadvantages of a metal roof is the high cost. Compared to other materials, the purchase price is usually higher. Due to the low maintenance costs, this pays for itself at a later date. There must be an exact planning phase. Building physics aspects as well as the roof construction have to be analyzed exactly. If a roofer does not work cleanly in the roofing or if there are deficiencies in the planning, unwanted background noises like crackles or pops can often occur later. The key to avoiding such noises is by appropriate insulation material and the correct roofing type.
The metal can be susceptible to denting, and because the roofing is secured to the decking with screws and neoprene washers, leaking can occur when those wear out. Those screws are exposed in a material such as Panel LOC Plus, and the neoprene washers can go bad in 15-20 years. A better choice is Standing Seam where all the screws are covered, yet it still not permanent.
