The Temperature Factor: How Weather Conditions Impact Roofing Installation

January 19, 2024

Asphalt Shingles

Asphalt shingles are one of the most popular roofing materials due to their durability, versatility, and affordability. However, temperature plays a crucial role in their installation. Ideally, asphalt shingles should be installed in moderate temperatures, typically between 40 and 85 degrees Fahrenheit.

Why is this? First, asphalt shingles become brittle and susceptible to cracking in colder temperatures. During installation, shingles need to be handled and nailed, and this flexibility can be lost when it's too cold, leading to breakage.

On the other hand, installing asphalt shingles in extremely hot temperatures can also cause issues. The heat can soften the asphalt, making it more prone to scuffing and marking during installation.

Metal Roofs

Metal roofing materials, while more resilient to temperature fluctuations, are not entirely immune to weather-related issues. In extremely cold weather, metal can contract, making it challenging to align and install the panels correctly. Conversely, in hot weather, metal expands, which could lead to issues with the fitting of panels if not correctly accounted for during installation.

EPDM (Rubber) Roofing

EPDM (Ethylene Propylene Diene Monomer) is a type of rubber roofing material often used on flat or low-slope roofs. It's known for its durability and relatively easy installation process. However, cold temperatures can make the adhesive used in the installation process less effective. This could lead to a weaker bond between the roof surface and the EPDM material, potentially reducing the roof's lifespan and effectiveness.

Tile and Slate Roofs

Tile and slate roofs are durable and long-lasting, but they can also be fragile if handled improperly. In cold weather, tiles and slates become more brittle and can crack or break during installation. That's why it's usually best to install these types of roofs in warmer, drier weather.


Weather conditions, especially temperature, play a crucial role in the roofing process. They not only affect the ease of installation but also the performance and lifespan of the roofing material. That's why it's important to plan your roofing project around the optimal time of year for the material you're using. And remember, a professional roofing contractor will know exactly when and how to install your roof to ensure it stands the test of time, no matter what the thermometer says.
