There are many advantages to metal roofs and the experts at McDonough Roofing can help you with the choice and installation of your new roof. Metal roofs are durable, have a life span of over 50 years, save energy, and reflect the heat of the sun. With installation by our expert team, your new metal roof will require minimal maintenance.

Metal roofing was historically installed in the 18th century, but at that time it was mainly lead or copper. As mass-produced steel became available in the mid-1800s, it was more common in everyday homes and barns. Around 1920 a light aluminum material that did not rust was introduced to the market along with special paint coatings which helped to add to the durability of the roof.

McDonough Roofing has installed thousands of metal roofs and the trend is on the rise. Although metal roofing components are expensive along with specially trained laborers, the installation of a metal roof can boost your home’s value by as much as 6%.

Metal roofs, depending on what type of metal is used, can cost anywhere between $7 to $20 per square foot which is about six times the amount of the installation of an asphalt roof. The lifespan of these roofs makes the cost worth it, though, with a duration of up to 70 years, where a traditional roof would have been replaced two to three times.

Many people are concerned that metal roofs are noisy; however, when a metal roof is installed over top of plywood sheathing and the proper underlay it is not any noisier than an asphalt roof. The products used for metal roofs are guaranteed by the manufacturer for as long as you own your home and most warranties are transferrable to the next owner, making them a great selling feature.

There are many different types of metal roofing and each has a positive feature whether it is the cost, the color, or its durability. It is best to speak to our experts at McDonough Roofing to help you to decide which material best suits your local climate while fitting into your budget.  As a bonus, this type of roofing will enhance your home’s style.


  • Aluminum:  this material is soft and available in a variety of embossed patterns.  Once it is painted you cannot tell that it is a less expensive material and can often look just like steel. This material can last between 30 to 50 years and will not rust, making it a good choice for areas of the country that experience acid rain or are near the ocean and have salt air.
  • Copper: One of the most expensive metals used for roofs, this material is easy to work with and can be cut and shaped without much effort. It can be uncoated to naturally turn the classic blue-green color over time. A copper roof can last up to 200 years.
  • Terne: this is a roof that is coated with tin and lead and was often used in 18th century Europe. Today’s version is lead-free and contains stainless steel in between layers of tin which is resistant to the worst weather.  As this material weathers, it turns a matte gray and can last up to 100 years.
  • Zinc:  this material is naturally resistant to the weather and is most often combined with titanium to give it more resistance to corrosion and to provide strength to the material. Over time zinc turns a bluish-gray color and can last between 80 and 100 years.
  • Steel: this is the strongest material and the least expensive of all the metal roofing options. The roofing material is dipped into zinc to galvanize it and prevent rust. This material once dipped can be painted and will last between 30 and 50 years.

Have the Experts at McDonough Roofing Install Your Metal Roof


Our experienced roofing installers will begin by removing your old roof. Although metal roofing can be laid directly over asphalt, it is a good idea to remove all the old roofing so that our team can inspect the sheathing and flashing. If necessary, we will replace those materials before we install your new roof to prevent leaks in the future.

A waterproof underlay is then installed on the roof to prevent water from ingressing. This material also helps to create a seal around each fastener that is used to hold the roof in place. Slip sheets are laid over the roofing underlayment so that the metal roof can expand and contract while the underlay’s integrity is protected.

The quality of the metal roofing job is only as good as the contractor. That is why you should contact McDonough Roofing; we are experienced and skilled with thousands of metal roofing installations under our belts.
