Through SUN, RAIN, WIND and SNOW... as the poem goes.
Does this sound familiar? No, we are not talking about the Post Office. We are referring to YOUR ROOF. Not usually the first thing on your mind until you see a leak. But think about what your roof needs to endure. The intense heat of the sun scorches the surface of the roof which raises rooftop temperatures 50 - 75°F above recorded temperature. Seasonal and weather changes also play a role in the aging of your roofing. Just consider the common situation in which the roof shielding you from the intense heat of the summer sun. On such a day your rooftop may reach temperatures in excess of 160°F. As the day changes a cold front comes through the area, bringing with it the violent thunderstorms and showers. Almost immediately, your roof temperature drops 60 - 100°F as it diverts the rains from entering your home. Thermal shocks such as this cause the roof deck beneath to expand and contract, placing a strain on the shingles. Day after day year after year this happens, resulting in the normal fatigue of your shingles. In addition to all of the climatic and external variables your roof has to deal with, improperly ventilated air space inhibits air movement and under most circumstances increases moisture content in comparison with properly vented attic air spaces. Heat shortens the shingles' life and moisture causes deck movement and/or deterioration, which has a direct affect on the performance of shingles.
