When it comes to the longevity of asphalt shingle roofs, the color of the shingles can play an unexpectedly significant role. This is because the color of your roof can affect both its temperature and exposure to UV rays, two factors that significantly influence the lifespan of roofing materials.
In this article, we’ll explore the durability of light versus dark-colored asphalt shingles and recommend the best roof colors for houses in Calgary.
Light vs. Dark Colored Asphalt Shingles
Light Colored Roofs: Light-colored asphalt shingles are known for their ability to reflect sunlight rather than absorb it. This reflection helps keep the roof and the overall home cooler, reducing the heat that reaches the indoor spaces.
The lower temperature means less thermal expansion and contraction of the shingles, which can help prevent premature aging and wear. Light colors such as beige, light gray, and pale blue are not just energy-efficient but also tend to have a longer lifespan due to reduced heat stress.
Dark Colored Roofs: Conversely, dark-colored shingles absorb more heat from sunlight, which can make your home warmer and, in turn, increase cooling costs in the summer.
The high absorption also means these roofs can reach significantly higher temperatures, which accelerates the aging process of the shingles by making them more susceptible to UV degradation and thermal cycling. Colors like black, dark brown, and forest green, while popular for aesthetic reasons, may not fare as well in terms of longevity.
Best Roof Color for Longevity in Calgary
Calgary’s climate is characterized by cold winters and warm summers, with a significant amount of sunlight year-round. For homeowners in Calgary, choosing the right roof color is crucial not only for aesthetic reasons but also for maximizing durability.
Given the specific weather conditions in Calgary, where sunlight exposure is significant but so is the need to manage both heating and cooling efficiently, a light to medium-colored roof can be ideal. Colors like slate gray, which can provide the dual benefits of reflecting heat in summer while not absorbing excessive heat like darker roofs, might be optimal. Such a color is versatile enough to manage seasonal changes effectively, reducing thermal shock and prolonging the life of the shingles.
Homeowners should consider consulting with roofing professionals to choose the best color based on their specific home architecture, local climate, and personal preferences, ensuring that their choice aligns with both their lifestyle needs and longevity expectations.
