The Pro’s And Con’s of Metal Roofing
Metal roofs may come in copper, zinc, aluminum, stainless steel and aluminum/zinc alloy.
Advantages of metal roofing are its durability in extreme wind and weather conditions and longer lifetime over other roofing materials. A roofer in Chicago is familiar with all the styles and code considerations for installing a metal roof.
The earliest metal roofs go back over 2,600 years ago in the Middle East. Most back then were rounded, dome structures. Metal roofs were for the most important buildings in the community and some were even made of gold.
Metal roofing comes in dozens of colors and can even be made to look like cedar shakes, tile or slate.Copper, while it develops a nice patina over time, is quite expensive and therefore not in use as much these days.
Aluminum roofing is resistant to corrosion and therefore used along many coastal areas. Zinc comes in various colors and even pre-weathered. Stainless Steel alloy comes in various finishes from highly polished to a dull matte.
With proper insulation, the noise most people would associate with having a metal roof is minimal but may be more than a traditional shingle-style roof. Some people are concerned that hail may damage a metal roof but modern manufacturing of metal roofs are rather resistant to hail damage.
Another concern is will a metal roof attract lighting? Lightning is attracted to the tallest of objects and were lightning to strike the metal roof it would dissipate across the entire surface.*
On the downside, a metal roof can be more expensive. Another concern is with snow sliding off. Usually, stops are installed to hold the snow in place over entryways. Like standard shingle roofing, there is an underlayment material which goes down first. To install a metal roof a roofer in Chicago lays metal panels which overlap each other.
This overlap is the seam which must be sealed properly to make it all weather-tight. Then there’s the metal trim to be applied as well. Various clips and fasteners are used. The appropriate clips and fasteners to use are based on local building codes and, in part, are determined by the amount of regional wind and load caused by snow and ice.
Some of the tools a roofer in Chicago would use which are unique to metal roofing material include:
- Tin Snips
These are used to cut and trim metal.
- Electric or Pneumatic Shears, Portable Profile Shearer, Electronic Nibbler
These are power tools used for cutting, shaping and trimming metal.
- Roofing Tongs, Hemming Tools, Seamers
Used to crimp and tighten the metal seams.
