Living in Miami means dealing with a lot of weather, from hurricanes to heat waves to downpours. Metal roofing can be an excellent solution for anyone concerned about the wear and tear of extreme weather on their shingles. But since replacing your roof can be costly, it’s important to consider all the pros and cons of having a metal roof before you make a decision.
One of the best advantages of metal roofing is that it’s much more energy efficient than asphalt shingles. It reflects the sun, so won’t absorb and trap heat the same way that an asphalt roof will, lessening the need for air conditioning. If you want to keep your house cooler or if you like the idea of being more environmentally friendly, a metal roof might be the way to go. Some types of metal roofing may even qualify for Energy Star tax credits depending on the specific properties of the materials used. Also, if you’re interested in using a cistern to cut back on your water bill, a metal roof is ideal for this setup, since the water will run off of it easily. The chemicals in asphalt shingles will tend to leach into any rainwater you collect, whereas galvanized metal roofs will tend not to pollute the water as much – although it’ll still be necessary to have a filtration system if you want to drink it.
Another significant advantage is it’s durability – a metal roof is more impervious to the rain than wood shingles are, meaning it’s less likely to get damaged by the rain over time. It won’t crack under the heat like other types of shingles sometimes do, and won’t tend to grow moss as easily. As mentioned in our previous post, both tile and metal roofing will protect your house against insect damage, and will prevent animals from being able to get into your attic.
One of the disadvantages of metal roofing is the noise. Rain falling on metal will be noisier than on other types of roofing materials, although this can be mitigated with proper installation. Depending on the type of metal roof you choose, some finishes can scratch or dent if a branch hits the roof in a hurricane, and sometimes the colour of a metal roof will fade over time – so it’s a good idea to ask about the different types of metal roofing available and the pros and cons of each specific type.

Metal roofing is more expensive than asphalt shingles, but some people would argue that the benefits of a metal roof make it worth the costs. It’s less expensive than concrete tiles, although slightly less durable – the lifespan of a metal roof is about 30 – 45 years, but the lifespan of a concrete roof can be much longer. A downside of concrete roofing tiles is that they’re heavy, wheras a metal roof is relatively light – so a metal roof would be a better option for shallow roof pitches.
One other disadvantage of metal roofing is that it can sometimes be costly to replace. Shingles can be replaced one by one, but since often metal roofing comes in larger sheets, if one gets damaged, it’s more surface area to be replaced. Metal roofing is also slippery and will of course get hot in the sun, so they aren’t as easy to climb on if you need to do so.
A common misconception about metal roofing is that it attracts lightning – this isn’t true! Lightning is seeking a path to the ground, and since metal roofs aren’t grounded, they won’t attract lightning. Another misconception is that they tend to fail at the seams, but this is only true if they aren’t installed properly. If you do opt for a metal roof, make sure it’s installed by a professional roofing contractor. Miami has a lot of weather and heat that a metal roof can stand up to quite well. The advantages of this type of roofing are pretty significant, so if you’ve been thinking about updating your roof and want to go for quality, it’s something to consider.
