Metal Roof vs Asphalt Shingles

When it comes time to replace the roof on your home, there are many factors to consider, and many decisions to make. One of those is deciding whether to go with asphalt shingles, or a metal roof. Read on to learn about the pros and cons of each.

Asphalt shingles are very affordable, and relatively easy to install. Metal roofs cost more, and require professional installation. Metal roofs require far less maintenance, however. With a lifespan of 50 to 70 years, they last almost three times longer than roofs made from asphalt shingles, which only last 20 to 25 years.

Asphalt shingles can be made to look like wood shakes, tiles or slate. They can also have a mix of lighter and darker colors, helping to give the roof a deeper look. Metal roofing tends to use solid colors, although it can also be manufactured to look like other materials, including shingles. As aesthetics can be a highly personal thing, it’s best to check out various pictures so you can decide which you prefer.

Roof repairs can be some of the most expensive repairs your home needs, so a durable roof creates more peace of mind. Asphalt shingles wear down over time. They can absorb water, causing them to lose their structure. Metal roofs, however, do not absorb anything. Unlike asphalt shingles, they are built to withstand changes in temperature without breaking down. 

Asphalt shingles require maintenance in the form of replacing sealants, as they break down over time and need to be replaced. Also rubber pipe boots, which are used to create a waterproof seal between the roof deck and protruding pipework, also need replacing if they break down.On a metal roof, rubber pipe boots are usually covered with metal. This not only improves the appearance of the roof, it also protects the rubber from the sun, making it last much longer.

Metal roofs are more ecologically friendly. They’re usually made with recycled materials, and the roof can be recycled after its use. While asphalt shingles can be recycled in some areas, it’s not an inexpensive process and often isn’t done, resulting in the shingles winding up in landfills. 

Metal roofs offer a greater degree of energy efficiency. This is because the metal is highly reflective, making it absorb less heat. A metal roof can keep your home cooler in the summer months, resulting in energy savings of 10-25 percent.

As you can see, while metal roofs cost more upfront, they more than make up for the extra cost thanks to their longevity, durability, and ability to lower your air conditioning bill. They extra cost is usually more than made up for in the long run.
