Yes, the colour of roofing shingles can affect their lifespan, but the impact is more indirect. Darker-coloured shingles tend to absorb more heat from the sun, which can lead to higher temperatures on the roof surface. This increased heat exposure can accelerate the aging process of the shingles, potentially reducing their lifespan compared to lighter-coloured shingles. However, factors such as shingle quality, proper installation, and roof ventilation play a more significant role in determining the lifespan of roofing shingles.
