Some Actual Disadvantages To Metal Roofs

Architectural shingles vs Metal roofing: Which Roof is Best?

Fear of lightning strikes may be an imaginary problem, but there are a few genuine disadvantages to metal roofs.

The one disadvantage that poses an actual safety risk is the fact that metal roofs are indeed slippery when wet or when covered with snow. It is never a good idea to climb on a metal roof when it is moist or covered with snow. They are so slippery that snow “avalanching” off the roof is a definite hazard in areas that experience heavy snowfalls in winter.

There are some advantages to this, since snow that slips off the roof can’t build up on top of it. People owning asphalt-shingled homes in heavy snow areas may need to rake snow off their roofs in winter, but this is never an issue on a home with metal roofs. But it is also possible for snow to avalanche off a metal roof in such quantities that it can damage decks, shrubs, cars, or even people.

In ski areas notorious for heavy snowfalls, metal roofs are often equipped with snow guardsmetal or plastic clips or even horizontal bars mounted to sturdy brackets. Homeowners can employ the same technology to prevent avalanches from the roofs of their homes.

    Steel Or Metal Roofing: Pros/cons & Avg Cost

    When talking about metal roofing, stainless steel tends to dominate the market. Steel is made up of iron and carbon, forming a strong metal alloy that can be rolled into various lengths, widths and Profiles.

    There are three varieties of steel, which are used in different circumstances, including:

    Galvanised Steel – Galvanised steel is manufactured using a layer of zinc. The zinc gives the sheet an extended life by protecting the inner layers of the steel from corrosion. Galvanised steel sheet metal and roofing panels are the most common steel metal roofing on the market.

    Galvalume Steel – Like galvanised, but instead of using just zinc to coat the steel, galvalume steel uses zinc metal with aluminum. Aluminum zinc protects the steel from a range of environments, including rust and corrosion.

    Thanks to its aluminum qualities, galvalume roofing can stand the test of time and offers improved protection. Care must be taken during the installation of sheets, as the surface can be easily scratched and marked.

    Weathering Steel: Weathering steel is a metal that has been designed and manufactured for the heavy steel industry and is commonly used for building projects such as bridges.

    The outer layer of metal is designed to corrode and rust, which, while sounding counterproductive, will protect the interior of the metal. Weathering steel is not the right metal for structural buildings because it will rust and require regular maintenance.

    Metal Roofs And Lighting

    Types Of Roof Shingles Commonly Used Carmel

    The misconception that metal roofs attract lightning is probably because metal itself is known as a good conductor of electricity, and people, therefore, assume that a metal roof must attract lightning. In reality, when lightning strikes, it is seeking a path to ground and almost always will strike whatever object is highest in the area that also has a direct path to ground. Your metal roof is not grounded, and thus lighting has no reason to strike it.

    A metal roof in no way makes your home more vulnerable or susceptible to lightning strikes.

    What Is The Installation Process For A Metal Roof

    A metal roof can be installed on your own with the right tools, knowledge, and assistance. However, the installation can be difficult and can vary slightly depending on the type of panels or shingles you choose. It is always advisable that metal roof installation should be done by experienced roofing contractors.

    Heres a generalized and quick step for installing a metal roof.

  • Prepare your roof surface: Clean and dry the roof surface and measure the length, width, and rise of the roof.
  • Install the edging: The edging, also known as eave flashing, is made up of metal strips that run around the edge of the roof.
  • Install the metal panels: Always start with the peak-to-eave distance that is the longest. Place the first sheet of metal on the roof so that it hangs over the edge.
  • Add the flashing: This is a metal trim that looks similar to eave flashing but is used to cover roof joints where different sections meet. This should be utilized as end caps over the tops of two sides that meet and in valleys.
  • Finish the roof: Ensure that the metal has completely covered the roof, that all edges are smooth and finished, and that no loose parts remain.
  • Stainless Steel Metal Roofing

    Stainless steel is an iron alloy made up of at least 10.5% chromium and contains other elements and metals/materials to obtain desired properties.

    When people think of stainless steel, they often think of large architectural structures such as elevators, bridges, building columns, handrails, etc. Or perhaps their kitchen appliances, cutlery, cookware, or beyond.

    However, stainless steel is also an option in the metal roofing industry primarily because this material is known for its strength which makes it a high-end specialty metal that could be the right material choice for some projects.

    Cons Of Galvalume Roofing

    Oil canning Oil canning is an inherent characteristic of light-gauge, cold-formed metal products, especially products with broad flat areas. It is a visual phenomenon seen as waviness or distortion in the flat surfaces of metal wall and roofing products. Oil canning is subjective and normally only an aesthetic concern that does not affect a products strength or performance. This occurrence is possible for any kind of metal roofing or walls, including Galvalume. But there are methods to minimize the appearance of oil canning, including:

    • Hiring an experienced contractor who knows the best methods to reduce oil canning, including:
    • Panel thickness
  • Buying trustworthy brands of coil
  • Using striations or bead stiffeners in the flat area of the panel to minimize the appearance of oil canning
  • Not suitable for animal enclosures or buildings Galvalume is not suitable for use on buildings where animals are housed or held. Manure from the animals breaks down into ammonia gas over time and then reacts with the Galvalume coating. This process breaks down the Galvalume coating and leads to the degradation of the metal. However, Galvalume is sometimes used on modern chicken houses built with a vapor barrier between the chicken area and the roof for appropriate ventilation. Its best to check with the manufacturer before putting Galvalume on an animal confinement building, as its often dependent on the specific design and use.

    Which Metal Roof Is Right For Your Residential Home

    There are two types of metal roof systems to choose from: standing seam and screw down panel. Remember, both metal roof systems have their place in the roofing industry, but a standing seam metal roof is the best choice for residential purposes.

    The main reason for this comes down to the expansion capabilities of the two types of metal roofs.

    For example, a standing seam metal roof systems panels are locked together at the seams or seamed mechanically. Under each rib is a clip that fastens the panels together and allows them to glide back and forth freely as the metal goes through thermal expansion.

    On the other hand, a screw-down panel metal roof system is installed by screws that are screwed straight through the panel. This leaves no room for expansion and contraction.

    Because theres no room to expand and contract, the screws will eventually wallow out the holes in the metal panels, and youll periodically have to pay to replace the screws with the next size up.

    Can you install a screw down metal roof over your home? Yes. However, its going to be expensive to maintain, and will be more prone to roof leaks.

    Top Considerations For Choosing Your Metal Roof

    There are many different metal roofing options to choose from, but not all of them are well suited for your home or business. The best type of metal roofing will depend on your personal needs and preferences. Thats why its important to think about the following criteria before making a final decision:

    The Lifespan Of A Standing Seam Metal Roof

    The lifespan of your roof is how many years you get out of it. You can think about it as your return on the investment you made in your roof.

    A huge advantage a standing seam metal roof has over most roof types is its durability and longevity. Your new standing seam metal roof comes with a 30-year paint warranty on the Kynar 500 painted finish on the metal panels.

    As long as its installed properly, theres no reason you shouldnt get through the paint warranty and get 30 years out of your standing seam metal roof. But just because the paints warranty is up doesnt mean the painted finish will disappear after 30 years.

    Under ideal conditions, your new standing seam metal roof could live up to 50 years. On the other hand, you could get 20 years out of a screw down panel metal roof.

    With periodic maintenance, you could possibly stretch it to 30 years. But remember, youre going to have to pay someone to change out the screws every 5 years if you want to get the most out of it.

    How Much Does A Metal Roof Cost

    For homeowners trying to get a long-lasting, unique roofing option that will require less maintenance, metal roofing might be the right path to take.

    Standing seam metal roofs are one of the more durable options out there for residential roofs, and when they are installed correctly, can last up to 70 years in good conditions. Screw-down metal roofs, when put over a barn, shed, or other unheated space, can also last for a very long time.

    Cons Of Copper Roofing

    Very expensive Copper is one of the most costly metal roof materials, as copper is not as abundant on the Earth. Plus, the price of copper fluctuates almost week by week. You can expect copper roofing to cost about $600 to $1,100 per roofing square .

    Expansion and contraction concerns In climates with striking temperature differences, copper roofing expands and contracts during heating and cooling cycles . Your contractor should ensure that your system can accommodate this thermal movement.

    Unpredictable patina Some people are drawn to the look of the patina that will happen on a copper roof, but some might not want this greenish-blue covering on their home or structure. There is currently no exact science to predict the color or time frame that patina will occur with copper. In some climates, the patina will turn a rich green in other environments, it will maintain a dark bronze look for decades.

    Run-off staining Copper roof rain run-off is known to stain siding, brick, concrete, other metals, wood, etc. Home or business owners need to be aware of this factor and ensure the contractors install the roof so the water can safely run off it without coming into contact with other stainable materials.

    Limited engineering options There are limited uplift-tested options available for most types of copper standing seam metal roof systems. If you find one, it will most likely be a mechanical seam profile .

    Exposed fastener roofing consists of overlapping panels that are fastened directly to the roof deck or framing through the face of the metal panel This type of metal roofing is defined as exposed because the fastener head remains visible once installed.
