Constant exposure to the elements can wear down roofing systems over the years. Some withstand the rigors of time better than others. Weathering describes the effects on shingles of long-term exposure to the elements, although it is a natural process of wear and tear.
Many factors can affect the rate at which shingles weather. Here’s a look at a few.
Shingle Quality
Quality is a factor that affects shingle weathering. Obviously, low-quality shingles always fail before high-quality ones. Shingle quality varies among manufacturers and among product lines of a single manufacturer. For your new construction project, only use weather-resistant shingle roofing.
UV Exposure
Roof slopes facing south experience higher thermal cycling and ultraviolet (UV) exposure. Some roof parts are more affected by prevailing winds than others. Flat roofs, on the other hand, are more exposed to UV radiation and shed moisture much slower than sloped ones. Also, homes at higher elevations get more UV radiation, which deteriorates asphalt shingles.
Prolonged exposure to UV rays cause protective layers of asphalt shingles to dry up. This leads to warping and cracking. Most asphalt shingles can withstand ultraviolet radiation for extended periods. The intense high-altitude sun, though, can speed up the demise of traditional shingles. Consult your local roofing companies for solar reflective roofing systems.
Local Climate
Harsh climates can significantly shorten the life of your roof. Wind, moisture and thermal cycling all speed up the deterioration process of roofing materials. Temperature swings also shorten roof lifespans because they cause greater amounts of expansion and contraction. Cold and low temperatures in winter can cause asphalt shingles to contract and crack. This weakens the shingle and reduces its life expectancy.
Inadequate Ventilation
Poor ventilation of the roof structure cannot cool shingles well, resulting in accelerated loss of volatiles and greater amounts of thermal cycling. Homeowners often misconstrue ventilation as a simple problem. The fact is, you can’t have too much or too little of it. For roofing new construction, it’s imperative that the roofs have sufficient ventilation.
