Just like everything else in life, a metal roof has its advantages and drawbacks. Of course, the material for your house’s roof should and will depend on your budget, the environment and conditions of your property, its surroundings, and the specific needs and style of your home. However, before making the decision of getting a metal roof, you should assess the pros and cons of a metal roof in order to make an informed decision. 


  • Fire resistant
    If fire approaches from outside, your metal roof will remain safe and sound, as the fire is not likely to have a negative impact on it.
  • Lightweight
    In comparison to other materials, metal roofs are on the lighter side of the spectrum, which might help homeowners reduce cost on supporting structure expenses.
  • Ideal for shedding snow
    The slippery and hard surface easily sheds snow and rain.
  • Long lasting
    Metal roofs usually come with a 30 year old warranty, and most products will remain intact for 20 to 50 years.
  • Mildew resistant
    Properly installed metal roofs will stay free from mildew and other kind of buildups.
  • Rot resistant
    A high quality metal roof won’t rot or rust.


  • Water resistant
    The interlocked panels and the slippery surface make metal roofs impenetrably when it comes to water.
  • Insect resistant
    Mites and other insects are not drawn to metal as they are to wood and other materials, making it the perfect choice for areas where these insects are abundant.
  • It can withstand extreme climates
    Metal roofs are resistant to the whims of climate if properly installed and treated.
  • Speed & ease of roofing installation.
    Metal roofs are quick and easy to install if you have a skilled contractor, which can make a huge difference when time is pressing.
  • Noncombustible
    Metal roofs are not only fire resistant but also noncombustible.
  • Low insulation R-value.
    Roof metals minimize the midday heat gain helping you save AC energy throughout the day. However, many systems have a dead-air space between the metal and roof deck to increase energy efficiency.
  • Minimal roof pitch
    Metal roofing materials can be installed on gently pitched roofs with minimal risk of leaking problems.
  • Maximum shedding of rain and snow
    Thanks to the slippery surface and its ease to conduct the heat, water easily evaporates and snow melts quickly.


  • Cost
    The biggest turn-off for most people when it comes to metal roofs is the initial cost since it equals the cost of premium materials roofing and ranges between $150 to $600 per square.
  • Noise
    Depending on your background and personality the loud sound of rain pouring over your metal roof might feel soothing and relaxing or like a total nightmare. If you relate to the latter, a metal roof might not be the best choice for you. However, structural barriers, sound-deadening insulation and solid plywood sheathing can be used to control the noise.
  • Denting
    Metal roofs are prone to denting the same way your car is. If you live in an area where hailstones are not uncommon, you might want to think twice about getting a metal roof. Nevertheless, some metal roofing types are guaranteed not to dent.
  • Lack of support for walking in some cases.
    In most cases, metal roofs are not ideal for walking on them as they are lightweight and do not offer enough support.
  • Slippery
    The slippery material can be great for keeping your roof clean and free of buildup. However, if you need to walk on your roof for whatever reason, this can be a bit of a problem.
  • Marring and care
    Depending on the finishing and the quality, metal roofs are prone to peeling, chipping, fading, scratching, chalking and wearing.
  • Reaction to temperature
    As you know, metal reacts to heat and coldness by expanding and contracting, and although new products come with fastening systems to adapt to whatever movements your roof makes, fasteners that secure the roofing may come loose rather frequently.
  • Difficult remodeling and modifications
    Metal roofs come with pretty standard characteristics, which means any modifications are a bit difficult to implement. Further, remodeling and replacement can become especially challenging if you’re unable to find the materials originally used for the space.
  • Indoor fires
    The fact that your roof is fire resistant may be a problem if a fire originates inside your house, given that often firefighters will cut the roof to access your home and put out the fire. A metal roof can make things a lot more difficult.
