Metal roofing has been around for quite some time, and has been used rather successfully in many areas of the country. Some might be under the impression that, with all of the moisture found in Pittsburgh, metal roofing is not a good choice for their home. This, however, is simply not the case. Iron City residents can be surprised at how well today's metal roofs can actually perform under moist conditions, and by the value that installing a metal roof can present to their home.
Types of Roofing in Pittsburgh
Most homes in Pittsburgh (and, indeed, the nation) are topped with asphalt shingles, which are certainly an easy and inexpensive choice. They do relatively well under most conditions, and are especially popular in areas prone to snow and cold weather. The biggest drawback to asphalt shingles is their life expectancy; while a high quality shingled roof might last 30 years, many experience problems well before that mark.
If you're lucky enough to have a slate roof (most common in Pittsburgh's north side), then, by all means, keep it as long as you can. Though slate roofs are decidedly difficult to work on (because the slate is very brittle and can crack under pressure), they can often last for over 100 years! However, for those who are thinking about replacing asphalt shingles in Pittsburgh, metal roofing is worth looking into.
Benefits of Metal Roofing in Pittsburgh
One of the best things about a metal roof is its durability. A properly installed metal roof can easily last 40 years or more. That's a long time! Though slate will last longer, most other roofing materials pale in comparison when it comes to longevity.
Metal roofs are generally a pretty low maintenance choice. Once they are installed, they require few repairs. This is because many factors such as low temperatures, lots of moisture, direct sunlight, and high winds don't have much of an effect on metal roofing.
The modern metal roof can look however you want it to look. Styles range from more traditional metal panels and shingles to metal that is made to look like tile or wood. It comes in a wide variety of colors and finishes. Whatever the rest of your home looks like, there's probably a metal roof that will compliment its appearance.
A metal roof is also a good choice for the environment. The amount of asphalt shingles that end up in landfills every year is incredible. In a city that's done as much work to become environmentally friendly as Pittsburgh, metal roofing, with its recycled content, low replacement rate, and ability to be installed over most existing materials, makes a bold and positive statement.
Metal Roofing Prices
Even those in the metal roof industry will admit that, on average, a metal roof can cost significantly more to install than an asphalt shingled roof. When you look at the long-term picture, however, it's easy to see how a metal roof could actually save you money over time. Despite the fact that you would most likely have to replace an asphalt shingled roof many years before a metal roof installed at the same time, you will also save money on the minor repairs and patching that, while common with asphalt, is quite rare for metal roofing.
