Metal Roofing: The Positives And The Negatives

If it's time to replace your roof, you may find that your roofing material choices have never been wider. For some, the attractiveness and longevity of a metal roof could place this particular roofing material choice under close consideration. To help you decide whether or not this type of roof could be the best choice for your home, read on to learn the positive and the negative points of metal roofs.

The Positive Points of Metal Roofs

1. Durability. Many metal roofs last far longer than asphalt shingles; from 40 to 70 years in some cases. Depending on your age when the roof is installed, this could mean that the chore of replacing your roof could be permanently crossed off your "to do" list for your lifetime.

2. Weather resistant.  Laying down metal roofs involves the use of interlocking metal panels or sheets, making your new metal roof extremely resistant to water and wind. 

3. Slippery. For those who live in snowy climes, snow accumulation on a roof can add extra weight, creating a dangerous situation. Unlike snow on a traditional asphalt shingle roof, snow on metal roofing won't cling but will instead just slide off.

4. Fire resistant. Many a home has caught fire from blowing or drifting hot embers from a nearby fire, but a metal roof will put a quick stop to that.

5. Rot. Mildew and rot can plague hot and humid locations, but metal roofs resist rot and mildew.

6. Insects. You can forget about problems with termites, at least on your metal roof.

7. Time. A metal roof can sometimes be installed right on top of your old roof, saving time and the mess that comes with the demolition of the old roof. Additionally, metal roofs come in large, ready-to-install sheets that can be quickly installed. This can be a real life-saver if bad weather is approaching.

8. Reflectivity. The shiny surface of metal will send heat back out, instead of into your interior. Your power bill may be lower if your air-conditioner doesn't need to work as hard to cool your home.

The Negative Points of Metal Roofs

1. Price. Be prepared to pay for the durability that a metal roof will provide.

2. Noise. There are those that love the sound of rain on a metal roof, and then there are those who find it too loud and distracting. Foam insulation panels installed beneath the metal sheets can help mitigate that issue somewhat.

3. Slippery. The same feature that allows the snow to slide off can also make it dangerous for walking across. You might not immediately anticipate anyone traipsing over your metal roof, but plumbers sometimes need to access the roof vents. As you might imagine, dings and dents in the metal can occur as a result of footsteps.

4. Lightning. This is actually only a perceived negative point, since no studies have shown that metal roofs attract lightning any more often than traditional shingle roofs do. For those uncomfortable with the prospect of this danger, lightning protection companies can install grounding to prevent conductivity.
