Installing a Metal Roof

Have you considered using metal roofing on your next roof replacement? As with all types of roof coverings, there are advantages and disadvantages of metal roofing.

Weighing the pros and cons of both to see what makes more sense for your location and budget will help you come to a reasonable conclusion. Let’s start with the positive aspects of using metal roofing.

According to State Farm Insurance Company:

Longevity. Metal roofs can last 40-70 years, depending on the material. Traditional asphalt roofing materials have an estimated life expectancy of roughly 12-20 years.
Durability. Some metal roofs can sustain wind gusts up to 140 miles per hour, will not corrode or crack, and may be impact-resistant (depending on which metal you choose). In addition, metal roofs don’t need the periodic costly maintenance that other roofing materials often require. However, they should be inspected periodically to make sure no repairs are required.
Safety. Metal roofs will not spark and ignite into flames during a wildfire or lightning strike.
Energy efficiency. Metal roofs reflect solar radiant heat, which can reduce cooling costs by 10-25%.
Environmentally friendly. Metal roofs not only have 25-95% recycled content, depending on the material used, but are also 100% recyclable at the end of their life as a roof. In contrast, most shingle tear-off waste ends up as part of the building-related waste stream — up to 20 billion pounds per year.

Tips for Proper Installation

Installing a metal roof is quite different than other types of roofing materials. It takes specialized training and experience to manage the installation without having costly errors.

The way each panel overlaps to interconnect is critical in order to allow water to flow from one panel to the next without being able to penetrate the area under the corrugated panel.

Setting the self tapping screws at the right depth is also an important aspect of securing the roofing properly. Using a magnetic driver bit sized correctly for the heads of the metal roofing screws and a power drill, you need to sink them in until the neoprene washer makes solid contact with the roof.

Metal roofing is great for Front Range commercial and residential property because it is lightweight, fire resistant, and it easily sheds the unavoidable snow of Colorado winters. With 300+ days of sunshine, the metal warms up fast and assists in this process.

Drawbacks to Choosing Metal Roofing

Even with all of the pros, there are some cons. Some people worry that a metal roof will be louder than other roofing materials, and in the case of a hail storm, it is. If it is installed over solid sheeting, though, it isn’t much different than other types of roofing shingles.

Speaking of hail, it can get dents from severe storms but withstands a lot of abuse, even high winds. The extremes of weather in Colorado can also cause expansion and contraction of the metal panels, causing the fasteners to loosen.

The biggest complaint, though, is the upfront cost, as outlined here:

The biggest drawback is initial cost. Metal roofing is equivalent in cost to other premium materials—from about $150 to $600 per square (100 square feet). Because of the material’s long-term durability, the trick is that you ultimately save the difference (and more) if you stay in the house for a long time and, of course, you save on seasonal maintenance. Of course, if you plan to move in a couple of years, you probably won’t get the return on your investment.
