In 2015, 750,000 homeowners installed metal roofs, and this number continues to grow as homeowners see the benefits. Metal roofs not only are appealing to the eye; they also have many advantages. If you are considering investing in a tin roofing, you know it’s a big investment. Let’s take a look at the advantages and disadvantages of tin roofing to see if this investment is right for you.
1. Durable and Long-Lasting
One of the top reasons homeowners select metal roofs is because they are much more durable than asphalt. Metal roofs can be two to three times stronger than asphalt and last up to 50-60 years.
Metal roofs don’t lose their luster with nature’s elements either. Rain, wind, and snow do not impact the roof because they are weatherproof.
Manufacturers agree that the lifespan of metal roofs is much longer and add a 30-50 year warranty depending on the make and style. Metal roofs can also withstand wind gusts up to 140 miles per hour. They don’t corrode or crack because of the rust-proof coating.
2. Environmentally Friendly
Asphalt shingles are made from petroleum which increases the need for fossil fuels. You need to replace asphalt shingles every 15-20 years, which means 11 million tons of asphalt shingles enter landfills each year.
Metal roofs are more sustainable because they use recycled materials, and steel roofs can be used over and over and not lose strength. Some metal roofs are light, weighing only about one-third that of asphalt roofing. This allows contractors to install metal roofs directly over the asphalt shingles without compromising the roof’s structure and creating additional waste.
3. Energy Efficient
Metal roofs can also save on heating and cooling because of the roof’s ability to reflect the sun. Metal roofs do not absorb the sun’s heat—they reflect it year-round. The ventilation under the sheathing also helps decrease the flow of heat on the roof.
The reflective properties can save homeowners 25 percent on cooling costs. Asphalt roofs absorb the heat in the summer, which in turn requires homeowners to crank up the air conditioning.
Metal roofs are much different than they used to be in the past with various finishes, colors, and shapes. You can choose between aluminum, tin, zinc, or galvanized steel to complete the look of your home. Asphalt shingles do not offer as many options.
If you want to change the color of your metal roof, some types of metal roofs have finishes that can be painted.
You can also find metal roof styles resembling clay tiles or wood shakes. The metal can mimic just about any look and give you that strong, durable structure.
5. Good for All Seasons
Along with reflecting the sun’s heat in the summer, a metal roof can also help in the winter. Ice dams are a significant issue in colder areas like the Midwest. Ice dams happen when there are poor ventilation and faulty insulation.
These ice dams cause leaks in the roof. Most of the time these leaks are in the attic, so the homeowner may not be aware for months.
Inadequate attic insulation allows hot air to rise up in the house and into the attic. This trapped heat warms the roof and then melts the snow lying on top. This results in the melted water running down the roof slope and then refreezing near the eaves, creating an ice dam.
Metal roofs prevent snow and ice accumulation, which means ice dams do not form. This is why metal roofs are great in cold climates as well as hotter climates.
6. Can Be Noisy
You’ve probably heard the old saying about “rain on the tin roof” because metal roofs can be a bit noisier than other roofs, especially if the rain is heavy or there is a thunderstorm. You can stop the extra noise by installing extra layers of insulation and solid sheathing to minimize the sound. This is an extra cost, so you will have to consider the noise factor when choosing a roof.
7. The Cost
Because metal roofs are so durable, the material is expensive. Depending on the type you choose, it can run anywhere from $120 to $900 per 100 square feet. This means higher-end metal roofing can cost up to 10 times the amount of asphalt shingles.
Labor is also more expensive because you need contractors with specialized training, equipment, and knowledge. You have to consider which type of roof is right for you, and you can check out various options. A metal roof may be the only roof you need to install on your home, so you get what you pay for.
Tin Roofing Repair and Maintenance
You may be wondering if there is any additional maintenance with tin roofs. These roofs are easy to maintain and simple to repair. You will need to re-apply the protective coating about every 5-7 years to make sure it can resist elements and keep its style.
You can then choose to change the color at this time as we mentioned above. The most common colors include red or black, but you can do any tint you like.
For scratches, the area will need to be wiped down with mineral spirits. Then you can touch up the paint with a paintbrush. You may likely be able to do this yourself for minor surface corrosion and paint touch-ups if you are okay with climbing up a ladder.
