Are Asphalt Shingle Roofs the Best for Summer?

May 31, 2024

Are asphalt shingle roofs the best choice for your home when summer rolls around? The fan favorite roof among many homeowners is known to resist high temperatures and intense sunlight. Should you replace your old roof with quality asphalt roofing shingles? In this post, we'll talk about the pros and cons of using asphalt shingle roofs for summer.

Pros of Asphalt Shingle Roofs in Summer

  • Affordability and Availability: One of the main reasons homeowners choose asphalt shingles is their cost-effectiveness. They are widely available and come in a variety of styles and colors, allowing homeowners to find a match for their aesthetic preferences without breaking the bank.
  • Durability: Modern asphalt shingles are designed to withstand a range of weather conditions, including the heat of summer. They are resistant to UV rays, which helps prevent premature aging and deterioration. High-quality asphalt shingles can last up to 20-30 years with proper maintenance.
  • Energy Efficiency: Many asphalt shingles now come with reflective coatings that help reduce the amount of heat absorbed by the roof. These "cool roofs" can significantly lower cooling costs by reflecting more sunlight and absorbing less heat. This is particularly beneficial during the hot summer months, as it helps maintain a cooler indoor temperature.
  • Ease of Installation and Maintenance: Asphalt shingles are relatively easy to install and replace, making them a convenient option for homeowners. Their maintenance is straightforward, and individual shingles can be replaced without the need for extensive roof repairs.
  • Ventilation: Proper attic ventilation is crucial for managing summer heat, and asphalt shingle roofs often incorporate ventilation systems that help expel hot air from the attic. This not only protects the shingles from overheating but also contributes to the overall energy efficiency of the home.

Cons of Asphalt Shingle Roofs in Summer

  • Heat Absorption: Despite advancements in reflective coatings, asphalt shingles can still absorb a significant amount of heat. This can lead to higher attic temperatures and increased cooling costs if the roof is not adequately ventilated. In extremely hot climates, this heat absorption can also contribute to the breakdown of the shingle material over time.
  • Thermal Shock: The expansion and contraction of asphalt shingles due to temperature fluctuations can lead to thermal shock, which may cause cracking or other forms of damage. While high-quality shingles are designed to withstand these stresses, cheaper options may be more susceptible to thermal shock.
  • Potential for Algae Growth: In humid summer climates, algae growth can be a concern for asphalt shingle roofs. This can lead to unsightly stains and potential roof damage. However, many modern shingles come with algae-resistant treatments to mitigate this issue.
  • Weight and Structural Considerations: Asphalt shingles are heavier than some alternative roofing materials, such as metal or composite shingles. This added weight requires a strong roof structure to support it, which might be a consideration for some homeowners.

Alternatives to Consider

While asphalt shingles are a solid choice for summer, other roofing materials may offer superior performance in hot climates

A great alternative to shingle roofs is metal roofing. With the right coating, it can reflect a significant amount of sunlight, which can drastically reduce cooling costs. They are also highly durable and resistant to extreme weather conditions.

Tile roofs, particularly clay or concrete tiles, provide excellent thermal resistance and are ideal for hot climates. They are long-lasting and offer a distinctive aesthetic appeal.

Also consider cool roofs. These roofs are specifically designed to reflect more sunlight and absorb less heat. They can be made from various materials, including specially coated asphalt shingles, metal, or membrane systems.
