Material Properties and Durability
Slate and asphalt shingles, while both serving the purpose of roofing, exhibit vastly different physical properties that directly impact their durability and lifespan. Understanding these differences is crucial for making an informed decision based on your specific needs and budget. This section will delve into the key material properties of each, comparing their weight, thickness, impact resistance, and responses to various weather conditions.
Weight and Thickness Comparison
Slate shingles are significantly heavier and thicker than asphalt shingles. A typical slate shingle can weigh between 2 and 4 pounds, while an asphalt shingle typically weighs less than 1 pound. This weight difference translates to increased structural demands on the roof itself; a slate roof requires a stronger supporting structure than an asphalt roof. The thickness of slate, generally ranging from 1/4 to 1/2 inch, also contributes to its superior impact resistance. Asphalt shingles, being considerably thinner, are more susceptible to damage from hail or falling objects.
Resistance to Weather Conditions
Slate’s natural density and composition provide exceptional resistance to wind, rain, and snow. Its inherent impermeability prevents water penetration, and its weight helps it withstand strong winds. Asphalt shingles, while generally resistant to moderate weather, can be more vulnerable during severe storms. High winds can lift and damage them, and heavy snow accumulation can lead to buckling or cracking, particularly in areas with significant snow loads. Prolonged exposure to heavy rain can also lead to water damage over time, especially if the shingles are improperly installed or begin to degrade.
Resistance to Extreme Temperatures
Slate’s inherent stability makes it highly resistant to both extreme heat and cold. It doesn’t expand or contract significantly with temperature fluctuations, reducing the risk of cracking or warping. In contrast, asphalt shingles are susceptible to thermal expansion and contraction. Prolonged exposure to intense heat can cause the asphalt to soften and become more vulnerable to damage. Conversely, extremely cold temperatures can make the asphalt brittle, increasing its susceptibility to cracking and breakage. For example, in regions with extreme temperature swings like the American Southwest or Northern Plains, asphalt shingle degradation is more pronounced than in areas with more moderate climates. Slate, however, maintains its structural integrity under these conditions, showcasing its superior longevity in extreme climates.
