Asphalt shingle roofing has an expected life span of about 20 to 30 years, but certain factors can increase or decrease its life span. Knowing what these factors are can help you choose favorable options or at least prevent premature failure. Let us give you a closer look at these factors:
Roof Pitch
Pitch is more than just the roof angle; it dictates the kind of roofing material that can be installed, as can affect how effective the roof is against winds. Residential structures often have steep-pitched roofs because of its visual appeal, as it’s readily visible from the ground. However, the same roofs are also vulnerable to high winds, making it unsuitable for tall or extremely wide structures.
Material
Certain materials last longer than others. We’ve mentioned that asphalt lasts about 30 years or so, but other options such as fiberglass and premium architectural shingles can last longer. In addition to shingles, other types like metal, tile and slate have inherently longer life spans.
Maintenance and Timely Repair
Following the prescribed maintenance routine, followed by timely roof repair, can help you get the most out of your roof. Scheduled professional maintenance helps locate potential problems in addition to apparent ones. Addressing these issues as early as possible helps prevent bigger and more costly repair work.
Local Weather and Climate
Outdoor conditions are a significant factor that affects your roof’s longevity, depending on how harsh or mild the local weather and climate is. One reason you should hire a local roofer like us, in addition to our familiarity with local building codes and conditions, is that we carry roofing products designed for the local climate.
Attic Ventilation
Trapped heat and moisture in the attic can damage the trusses, rafters and roof deck, which can potentially shorten a roof’s life span, as well as damage the attic insulation and encourage mold and mildew growth. If you’re in the market for a new roof, make sure the roofing system includes ridge vents and a properly designed ventilation system to avoid these problems and prolong its life span.
