If your aging roof is in need of replacement, you may be considering a new material, such as metal. Metal roofs have many great advantages, but there are also some drawbacks to consider. If you are interested in installing a metal roof, check out these must-know know facts first.
It Should Never Need Replacing
If properly installed and cared for, metal roofs can last as long as your house, because they are known to last 50 years or more. This means once you get a metal roof, you probably won't ever have to worry about replacing it again in your lifetime. On top of that, metal roofs don't require much maintenance. It's not common for debris to collect on the roof, but if it does, make sure to remove it. Other than that, you just need to worry about regular inspections to check for any problems, such as sealant failures, damage from hail, peeling paint and broken fasteners.
Metal Roofs Are Perfect for Any Climate
Metal roofs are great no matter where you live. Despite its low insulation R-value, metal roofs are still energy efficient in hot climates because they reflect the sun's heat. In colder climates that see large amounts of snowfall, the smooth, hard surface of the metal roof allows the snow to slide off, preventing it from adding extra weight and strain. In humid climates and cooler areas that see a lot of rain, the water also tends to slide right off instead of seeping through cracks. Plus, it isn't prone to mold, mildew or algae growth.
Installation Is Fast and Easy
Instead of using many small shingles, metal roofs come in larger sections, which makes installation faster and easier. In some cases, because the metal is so light, you don't even need to tear-off the old roof. The metal can simply be placed over it, making the process even faster. Plus, because of the light weight, you don't need to spend extra time having supports installed.
There Will Be Noise
Rain and hail hitting the metal roof make a lot more noise than with other types of roofing materials, and not everyone enjoys the constant tapping. There are some ways you can reduce the noise. Some materials have structural barriers that stop the drumming effect. Other ways to reduce the noise include sound-deadening insulation and solid plywood sheeting under the metal. Most noise-reducing features, however, must be installed when you install the roof, so make up your mind before the process begins.
Replacing Damaged Sections May Be Necessary and Is Difficult
Metal roofs are quite durable, but they're not impervious. In particular, hail is a danger because it can cause dents, especially in aluminum and copper roofs. Some metals guarantee to never dent. Other dangers include wear and tear from too much foot traffic, fading, scratching or chipping. If you do need to replace a portion of your roof, it can be difficult because the metal sheets are so large. Even if there is only one dent, you'll have to replace an entire sheet. If it's been several years since the roof was installed, you may even have a hard time matching the material.
Metal Roofs Are Expensive
Metal roofs are one of the most expensive options. For a standard three-tab asphalt shingle roof, you pay about $90 per roofing square, but the most common metal roofs (steel and aluminum) cost between $265 and $375 per roofing square. If you want copper or zinc, the price rises to between $700 and $900 per roofing square. Although you probably won't ever need to replace a metal roof, the high cost means that you'll still end up saving money in the long term if you choose a standard asphalt roof and have it repaired once in your life. Of course, a metal roof saves you the hassle and annoyance of needing a replacement.
Because of their high price, don't expect a metal roof to save you money in the long run. However, metal roofs do save you the headache of replacement and they require little maintenance. To learn more about metal roofs, contact a roofing company like Acoma Roofing.Share
