Virginia Beach Roofing: Article About Factors Affecting A Roof's Lifespan
Roofs vary widely in how long they last, and their lifespan is largely determined by the kind of roofing material used. However, far more affects a roof's longevity than the type of shingle, shake or tile that is used. Homeowners investing in new roofs should keep several other factors in mind, including the local climate and the house design. Most local Virginia Beach roofing contractors can advise their clients on what to expect with a given kind of roofing material. For general information, homeowners can always look to the manufacturer's warranty for a sense of how long the roof should withstand the elements. Beyond that estimate, learning a bit about roofing longevity can help the homeowner make an even more informed purchase.
Any roof's primary purpose is to protect the building from inclement weather. Therefore, roof materials are designed to stand up to rain, sleet, snow and wind over long periods. How well a roof can withstand these forces is one of the greatest factors that determines its longevity. Roofs that receive many hours of direct sunlight typically show signs of weathering more quickly and need to be replaced more often.

On the other hand, roofs in areas with severe winter weather are susceptible to specific cold weather kinds of damage, such as ice dams. Overall, perhaps the greatest threat to roofing is a climate with severe fluctuations in temperature. In these cases, the alternating heat and cold can cause elements of the roof structure to rapidly shrink and expand, which puts tremendous stress on the roofing material involved.
Aside from the climate, the architectural design of each individual house influences how long the roof holds up. In many cases, low sloping roofs put a greater burden on roofing materials than roofs with a steeper pitch. The reason is that water and snow slides off the higher pitched roof more quickly. By contrast, low roofs are more likely to have issues with snow accumulation or pooling water. In addition, complex roof designs often have more "weak points" than simpler designs. As a result, these more complex roof shapes may sustain water damage more easily. Once water damage begins, the longer that it goes undetected, the more it endangers the roof's longevity.
For homeowners selecting roofing material for a new roof, it's worth bearing in mind that multiple factors affect roof longevity. By weighing climate factors, architectural design and the type of roofing material used, homeowners can arrive at an educated guess of how long they can wait before another roof replacement is necessary.
