1. Metal Roofs Are Not Just a Novelty
When you think of metal roofs, do you envision a house in the mountains? Think again. Metal roofing’s market share is increasing 3% each year and has been doing so over the past few years. As of 2019, 15% of the United States, currently use metal roofing materials. On the flip side, asphalt shingle roofing has fallen to 59%. It is safe to assume that metal roofing is now more common, and with that, comes increased availability.
2. Metal Roofing Can Be Installed Over Existing Roofs
This is a less commonly known fact: there is no need for shingle removal. This is obviously the less expensive option. You still need to do some homework before jumping into this option, though. Check your local building codes, just in case, they may say that your roof requires a total strip.
Although installation over current roofs is an option, most installers prefer to remove the shingles. This is because moisture can build up and cause mold. There are ways to combat this though. Vented metal roofs eliminate the risk of mold. Also, installation over furring strips ventilates between areas.
3. Metal Roofs Are No Noisier Than Asphalt Roofing
There is a common misconception that metal roofs are louder. This is not true. If your roof is properly installed, metal is no noisier than any other type of roof. Metal roofs are typically installed over a solid substrate. Furthermore, the attic and insulation provide a sound barrier, and from inside, almost no one tells a difference.
4. Metal Roofing Does Not Attract Lightning
Throughout the years, there has been a buzz that metal roofs attract lightning. There is absolutely zero evidence to support this. According to a technical bulletin from the Metal Construction Association, “Metal roofing does not in any way increase the risk of a lightning strike.” If metal roofing does get struck by lightning, it is less combustible than wood shakes or shingles. Lightning seeks a path to ground. Metal roofs are isolated structural components.
5. Metal Roofing Can Be More Cost-Effective
Although it may cost more upfront, most metal roofs carry warranties to 30 years, but last 50 plus years. According to State Farm Insurance statistics, metal roofs have a longevity of 40 to 70 years. It is very rare that one homeowner will install 2 metal roofs over one lifetime, but this is common for an asphalt shingle roof.
6. Metal Roofing Is Impervious to Fire, Rot, and Insect Damage
If you are looking for the safe option, metal roofs are virtually fireproof. Insects such as termites can never eat metal roofing. On top of that, a metal roof is impervious to rot and mildew. Since it conducts heat quickly from the sun, snow slides off more quickly than typical roofs.
7. Metal Roofs Are More Energy Efficient
Metal Roofs reflect solar radiant heat. This can reduce cooling costs by ten to twenty-five percent. You can also choose to coat your metal roof with a shiny or granular coating that can maximize reflection, thus saving more money.
8. Metal Roofing Can Work on Roofs With Low Slopes
Standing-seam can work on gently pitched roofs. It is installed in large sheets with seams that are raised and sealed. However, some slope is necessary. The takeaway is that most homes can have metal roofing.
9. Severe Hail Can Ruin Metal Roofing
Metal roofs are considerably more durable and maintenance-free, however, they are not indestructible. Large hail is not good for metal roofing. Aluminum and copper are susceptible to denting, especially when hail reaches softball size. Steel is harder and fares better in hailstorms. Pea or dime-size is rarely a problem, but hail any larger definitely can be. Large hail can also destroy an asphalt shingle roof, as well. If you live in a hail prone area, make sure to have a good homeowners insurance.
10.Installation and Repair Usually Requires a Professional
Even if you could purchase the materials yourself, doing it yourself is not advised. As mentioned, these materials are generally available only through select retailers. The technique for installation and repair are specialized skills, and maintenance shouldn’t be an issue because problems are rare with metal roofs.
