Don’t Fall for These Myths About Metal Roofs
When considering the installation of a metal roof for your home, it’s important to separate myths from facts. To help make sure your decision is based on fact, not fables, this article will discuss and debunk the most common myths about metal roofs.
Myth #1 – Metal Roofs are Noisy
If you’re researching metal roofing, you may have heard that metal roofs are too noisy during rain or hail storms. This is far from reality. With a roof insulated with waterproof acoustic underlayment, metal roofing is actually just as quiet as any other roof material.
How Acoustic Underlayment Can Help
Using an acoustic underlayment is one way to minimize noise created by rain or hail on your metal roof. The acoustic layer helps absorb the sound of rain or hail as it hits the roof, reducing any outside noise. Furthermore, this acoustic insulation minimizes the chances of sound transmission from outside back into your home.
How to Install Acoustic Underlayment
Many roofers are familiar with the installation of acoustic insulation in residential rooftops, and proper installation is key to ensuring the desired noise control. To ensure the job is done correctly, the acoustic layer should cover the entire roof and be correctly integrated with the metal roof fasteners.
Myth #2 – Metal Roofs are Highly Reflective
Some people believe that because metal roofs are reflective, they will cause their home to be unbearably hot during the summer. The truth is that most metal roofs are, in fact, quite low in reflectivity and can actually help keep your home cool in the summer.
Types of Metal Roofing
Metal roofs can be made from many different types of metal, each with its own level of reflectivity and energy efficiency. The most common type of metal roofing is aluminum, which is highly efficient and low in reflectivity. There are also other types of metal roofing, such as bronze, copper, and steel, which are all slightly reflective but not as much as aluminum.
Understanding Solar Reflectance
Solar reflectance is a measure of how much sunlight is reflected off a surface. It is measured on a scale of 0-1, with 1 being the most reflective. Aluminum roofing typically has a solar reflectance rating of around 0.30, which is significantly lower than other roofing materials such as tile, which can have a solar reflectance of 0.75.
Energy-Efficient Coatings for Metal Roofs
To further reduce the amount of reflectivity from a metal roof, you can also add energy-efficient coatings. These coatings are designed to further reduce solar reflectance and help keep your home cool during the summer months.
Myth #3 – Metal Roofs are Not Durable
Many people think that metal roofs are not as durable as other roofing materials, such as asphalt shingles. This is simply not true. Metal roofs are incredibly durable and can last up to 50 years with proper maintenance.
The Life Span of a Metal Roof
The expected life span of a metal roof depends on the type of metal used and how the roof is installed. Aluminum and copper roofs typically last anywhere from 40 to 50 years, while steel roofs can last up to 70 years if properly maintained.
Avoiding Rust and Corrosion
To ensure your metal roof lasts as long as possible, it’s important to avoid rust and corrosion. To reduce the chance of rust and corrosion, metal roofs should be installed in a dry environment and kept away from harsh chemicals and pollutants. Additionally, metal roofs should be inspected regularly for any signs of damage.
Myth #4 – Metal Roofs are Not Fire Resistant
Some people believe that metal roofs are not fire resistant, but this is not the case. Metal roofs are actually inherently fire resistant and can withstand even the most extreme temperatures without experiencing any damage.
The Reasons Why Metal is Fire Resistant
The fire resistance of metal roofing is due to several factors. For starters, metal roofs are made from highly durable materials such as aluminum, steel, and copper, which are all naturally fire-resistant. Additionally, metal roofs are non-combustible, meaning they won’t ignite even in the highest temperatures.
Metal Roof Coatings to Improve Fire Resistance
For an extra layer of fire protection, metal roofs can be coated with fire-retardant paints or sealants. These coatings help protect metal roofs from heat and flames by forming a barrier between the metal and the source of the fire. It’s important to note, however, that these coatings are not a substitute for proper fire safety precautions, such as installing smoke detectors.
Myth #5 – Metal Roofs are Too Heavy
Many people think that metal roofs are too heavy for their homes, but this is not true. Metal roofs are actually quite lightweight and can be installed on any type of home without any structural reinforcement.
The Weight of Metal Roofs
The weight of metal roofs varies depending on the type of metal used. Aluminum roofs weigh anywhere from 40 to 100 pounds per square foot, while steel roofs can weigh up to 250 pounds per square foot. In comparison, asphalt shingles can weigh up to 500 pounds per square foot.
Installing a Metal Roof
Even though metal roofs are lightweight, it’s important that they are properly installed. To ensure the roof is properly installed and secured, it’s recommended that you hire a professional roofer with experience in metal roof installation.
