When someone mentions a metal roof, the image that comes to mind may be an old, shabby lean-to with a wavy tin roof. However, modern-day metal roofs are nothing like that.

Nowadays, roofing materials are typically made of a combination of asphalt/fiberglass or wooden shingles. Some flat roofs are covered with tar, while rubber is quickly becoming a popular roofing option. As individuals strive to embrace eco-friendliness and discover materials that require minimal maintenance and upkeep, new trends are emerging in the roofing industry.

In spite of the fact that metal roofs can be expensive and require professional installation, they’re becoming a popular choice because of their durability. Aluminum and steel are the most frequently used metals for roofing, but a copper roof may also be available. Regardless, you won’t be stuck with corrugated tin as metal roofing materials can be formed to resemble traditional roofing materials like Spanish tiles or slate [source: Vandervort].

Another reason metal roofs are increasingly popular is their resistance to fire. They’re also lightweight and reflect the sun, which can help reduce summer cooling bills. While metal roofs often require professional installation, they’re still easier and quicker to install than traditional roofs [source: Vandervort]. However, if you need to make any adjustments or repairs, it may be more difficult than with conventional roofing materials.

This article will delve into the details of metal roofing materials and roofing underlayment materials. So, put on your hard hat and keep reading to learn about the five primary types of materials used in metal roofing.


Metal Roofing Materials

Now that you know your new metal roof won’t be corrugated tin, there are five primary metals — varying in price and longevity — that are used in roofing.

There are several options for metal roofing materials, including Steel, Stainless Steel, Aluminum, Copper, and Alloys. Steel is the most common and experts have found ways to protect it from rust. Stainless Steel doesn’t need extra coatings but is expensive. Aluminum is lightweight and won’t rust but needs coating to look natural. Copper is becoming more popular but is also very expensive. Different metal alloys can be used for various needs but can be expensive. Metal roofing can last more than 50 years, with copper and aluminum roofs lasting more than 75 years. Roofing underlayment materials, such as rubberized asphalt, organic, fiberglass, and synthetic, protect the roof and can be exposed for up to six months. Choosing the right underlayment can keep moisture and air out, giving the roof a longer life. Green options are available for those interested in LEED certification.

Roofing materials offer a variety of options to cater to your needs, ranging from organic underlayment to elegant copper roofs. It’s fascinating how a roof can have so much personality. If you’re interested in learning more, check out the links on the next page.

Recent times have seen synthetic roof underlayments taking center stage, especially in post-Katrina New Orleans. In the wake of the disaster, contractors used synthetic underlayments as a temporary roofing solution since many types can be exposed for up to six months. These roofing underlayments proved to be more durable than FEMA’s tarps and became a permanent part of the houses as they were repaired. This is in contrast to plastic tarps, which have to be removed and discarded.

1. What are the most common types of roofing materials?

The most common types of roofing materials include asphalt shingles, metal roofing, clay tiles, concrete tiles, slate, and wood shingles or shakes. Each type of material has its own advantages and disadvantages, so it’s important to choose the right one for your specific needs and budget.

2. How long do roofing materials typically last?

The lifespan of a roofing material depends on several factors, such as the quality of the material, the installation process, and the climate in which it is installed. Generally speaking, asphalt shingles can last anywhere from 15 to 30 years, while metal roofing can last up to 50 years or more. Clay and concrete tiles can last up to 50 years as well, while slate can last up to 100 years.

3. How do roofing materials protect a home?

Roofing materials provide protection for a home by preventing water and other elements from entering the structure. This helps to keep the interior of the home dry and free from damage caused by moisture. In addition, roofing materials can also provide insulation to help regulate the temperature inside the home.

4. What factors should be considered when choosing a roofing material?

When choosing a roofing material, it’s important to consider factors such as cost, durability, energy efficiency, and the style of your home. You should also take into account the climate in which you live, as some materials are better suited for certain climates than others.

5. How is a roofing material installed?

The installation process for a roofing material will vary depending on the type of material being used. Typically, the old roofing material will be removed and the roof deck will be inspected for any damage. From there, the new roofing material will be installed, starting at the bottom of the roof and working upward. Flashing and other accessories will also be installed to ensure that the roof is watertight.

6. Can roofing materials be recycled?

Many roofing materials can be recycled, including asphalt shingles, metal roofing, and clay and concrete tiles. Recycling these materials helps to reduce waste and conserve natural resources. If you’re considering a new roof, be sure to ask your contractor about recycling options.

7. What maintenance is required for different roofing materials?

The maintenance required for different roofing materials will vary. Asphalt shingles may require occasional cleaning and repair of damaged shingles. Metal roofing may require periodic inspections to ensure that the fasteners are secure. Clay and concrete tiles may require occasional cleaning and replacement of damaged tiles. It’s important to follow the manufacturer’s recommendations for maintenance to ensure that your roof lasts as long as possible.
