Asphalt shingles are one of the most widely used roofing covers because they are generally inexpensive and pretty easy to install. Asphalt shingles are known to last longer in cooler climates than warmer ones. Thermal shock (when the temperature changes dramatically in a short amount of time) is one of the things that can damage this type of roof. The protective function of asphalt shingles comes from the long chain hydrocarbons impregnating the paper. Over years and years in the hot sun, the materials soften and are washed away with rain, eventually all of the oil drains off and the nail head is visible above the shingle. Once the nail is exposed, the water running down the roof can seep into the building around the nail head. If this happens, the roof will start rotting and causing moisture damage to the ceiling inside.
