Slate contains naturally-occurring iron, which leached out of the slate and damaged the copper. We have seen a copper metal roof erode because it was connected to a slope roof system made of slate. In addition, copper is a very reactive metal and may corrode if it comes in contact with other minerals or metals. Also, because copper metal is softer than steel, there will be a higher chance that it gets damaged when hail or branches strike the metal roof. These small roof leaks might be hard to catch in the beginning, but can cause lots of damage. Though the copper will not fail, the solder usually will within a few years. The main problem with copper metal is that when you are putting together a copper roof system, there is a lot of solder used on penetrations and flashing points. When applied, it has the gleam of a new penny, and as it weathers, it takes on the cool green metal worn by the Statue of Liberty. Copper roofing product has lots of benefits, starting with appearance. Having discussed the pros and cons of shingle roofs, let’s look at metal roofs. Metal Roofs: Copper, Aluminum & Boral Steel Though this doesn’t happen to every roof, we often notice that because the asphalt in shingles is of inconsistent quality, some roofs experience dark streaking sooner than others, even though they were made by the same manufacturer. After 10 years, it will spread to other areas, even if they are constantly exposed to the sun. If there is any shading on the roof from trees or high walls, the roof will start to get dark streaking on those areas. If a homeowner is worried about how the roof will look after 5 years, they should be worried about putting an asphalt shingle roof on their home. The cost of re-roofing a shingle roof every 5-10 years means that you end up paying more than you would for a metal roof. In that context, the return on investment on asphalt shingle roofs is terrible, especially for a homeowner that is planning to live there for a long time. “The cost of re-roofing a shingle roof every 5-10 years means that you end up paying more than you would for a metal roof.” “…the return on investment on asphalt shingle roofs is terrible, especially for a homeowner that is planning to live there for a long time.” That means those handsome asphalt shingle roofs might only last some homeowners 10 years. Because shingles dry out in the sun, if you manipulate them to switch out other shingles, they will start to crease and fracture. Around the 10-year mark, shingles will begin to detach during high winds, and trying to repair the shingles after they have been on the roof for 10 years is next to impossible because other shingles get damaged during roof repairs. Many manufacturing reps will tell you that the roofing shingles made using the new materials and methods will last for about 25 years, though the warranty says that they’re good for a lifetime. However, for many homeowners the drawbacks of asphalt shingles outweigh the benefits. Asphalt roofing shingles come in a variety of colors and look brand new for 5-10 years. They cost significantly less than a metal roofing system, which can be especially attractive for rental property owners and home sellers. There are several notable benefits to asphalt roofing shingles. These roofing simulations determine that the roof’s shingles are able to last at least 25 years. Today, shingles hold up better under accelerated aging simulations. In response, shingle roofing companies began using fiberglass mesh in the shingle cores and higher-quality asphalt, including protective compounds to better withstand ultraviolet degradation. Thousands of businesses went into bankruptcy due to class action lawsuits brought against them, alleging poor shingle quality and retention. The asphalt shingle roofing industry faced severe problems at the beginning of the 21st century. We’ll start with shingle systems, which have improved greatly in the last 20 years. Today we’re going to look at a few roofing systems that are available for all modern steep slope roof homes. There are some types, like slate roofs and Spanish clay tile, which we will not be discussing due to the weight of these roofing systems and the fact that they can’t be installed on all structures, unless the roof was designed to bear the extra weight. Roofs come in many shapes and sizes, just like the houses they protect.
