During the Stable Phase, these signs of aging will slow down dramatically.  The duration of the stable phase may last 20-30 years, but is dependent on many factors including the construction of the asphalt shingles, the condition of your roof and roofing ventilation, the slope of your roof, as well as the workmanship of your roofing contractor. Near the end of the expected life of asphalt shingles, the aging process begins to speed up.  This is what is called the Final Phase, during which most homeowners start to think about replacing their asphalt shingles. Curling: One of the things you may notice is a slight curling of the shingles along the bottom edge, particularly during cold weather.  This is a normal occurrence of asphalt shingles and results from the natural loss of the oils from the asphalt covering the felt.  As the asphalt loses its oil, it slowly becomes more rigid, and may shrink at...
