There are many roofing types on the market each with their own advantages and disadvantages, but none are as popular, or as common, as asphalt roofs. But even asphalt roofs come in hundreds of colors and styles. The downside of asphalt roofing, however, is their relatively short lifespan. While slate and copper roofs can last up to 50 years and wood shake roofs can provide 30 years of service, asphalt roofs generally last about 20. This life expectancy is dependent on some factors including weather, however. Atlanta Pro Roofing is a local roofing specialist, and these are some weather conditions that we have noticed most affect the lifespan of asphalt roofing.
Ultraviolet Radiation
Exposure to ultraviolet rays is not just bad for your skin. These powerful rays will alter the chemical makeup of the tiles. As the chemical bonds in the tiles are weakened, granules fall off the shingles, tiles become discolored, and the roofing loses its protective coating. There are products on the market to protect against UV rays as well as shingles that are thicker and use better granules than standard shingles.
Rapidly Changing Temperature
Some areas in the United States are susceptible to thermal cycling. This is the rapid change in temperature between day and night. During the warm days, asphalt shingles expand. Then, during the cold of the night, the shingles contract quickly. This constant expansion and contraction will eventually cause tiles to crack and even split. Rain accelerates the effects even further as water seeps into cracks and freezes, expanding cracks. Be sure to frequently inspect for loose flashings and tiles to protect against this phenomenon.
Wind
This one should not be much of a surprise and there is not much detail to go into here. Shingles along the periphery are especially prone to wind pressures. Fortunately, your asphalt can withstand a little bit of wind. But even those small breezes can be destructive if your shingles and tiles are already damages and loose on the edges.
Rain
Did you know that just an inch of rainfall can drop around 1,500 gallons of water onto your roof? That is a lot of pressure, but the thing about rain is that water has a way of finding the weak spots in your roof. Water will find its way into cracks and crevices. Once water seeps below the roof deck, it can cause rot, mold, and mildew. In extreme circumstances, the rainwater can even get to your electrical system.
