At what temperature should you not shingle a roof?

Undertaking a roofing project is a significant investment for homeowners, and the success of the project is often influenced by weather conditions. Roofing material manufacturers provide guidelines on the ideal temperature range for shingle installation to ensure optimal performance and longevity. In this article, we’ll explore the factors that influence the temperature limits for shingling a roof and provide insights into when it’s best to schedule this crucial home improvement task.

Understanding Asphalt Shingle Installation:

Asphalt shingles, one of the most popular roofing materials, have specific temperature requirements during installation. The ideal conditions for shingle installation involve moderate temperatures that allow the shingles to adhere properly, creating a watertight seal. Both high and low temperatures can present challenges that may compromise the effectiveness of the installation.

  1. High Temperatures: Extremely high temperatures, especially during the peak of the day, can soften asphalt shingles. When shingles are too soft, they may become more susceptible to damage during installation, and the adhesive strips may not bond effectively. Additionally, working in intense heat can be physically demanding for roofers, affecting the overall quality and efficiency of the installation process.
  2. Low Temperatures: On the other end of the spectrum, very low temperatures can also pose challenges for shingle installation. Cold weather can make asphalt shingles brittle and less flexible, increasing the risk of breakage during handling and installation. The adhesive strips may also become less pliable, affecting their ability to form a secure bond.

Guidelines for Shingle Installation Temperatures:

So, at what temperature should you not shingle a roof? While specific recommendations may vary slightly among manufacturers, a general guideline is to avoid shingling a roof when temperatures fall below 40°F (4°C) or exceed 85°F (29°C). These temperature limits help ensure the proper adhesion and sealing of the shingles, optimizing their performance and longevity.

Ideal Conditions for Shingle Installation:

  1. Mild Temperatures: The best conditions for shingle installation typically occur during mild, moderate temperatures, typically between 45°F to 85°F (7°C to 29°C). Working in this temperature range allows the asphalt shingles to be flexible enough for easy handling and placement while ensuring proper adhesion and sealing.
  2. Overcast Days: Overcast days can be advantageous for roofing projects. The absence of direct sunlight can help prevent excessive heating of the shingles, providing a more extended working time for roofers. Moreover, working in cooler conditions can be more comfortable for the roofing crew.


Timing is crucial when it comes to shingling a roof, and understanding the temperature limits for installation is essential for a successful project. Whether you’re a homeowner planning a DIY roofing project or hiring professionals, paying attention to weather conditions and adhering to recommended temperature guidelines ensures that your investment in a new roof will withstand the test of time and the elements.
