As temperatures rise, so do the challenges of working with roofing adhesives. It’s easy to assume warmer conditions make application easier—but heat can significantly impact performance, application, and results.
Higher temperatures can thin products, reduce cure times, and affect overall performance but with the right storage, preparation, and techniques, contractors can still achieve reliable, high performance bonds during summer months.
How to store adhesive products in warmer weather
Proper storage is critical during summer months.
Adhesives should typically be kept between 60°F and 80°F (16°C–27°C) in a protected area. Always check the recommended temperature storage range for the specific product you’re using.
Best practices:
- Do not leave product outside exposed to the elements or in direct sunlight.
- If products are stored on the roof, they should be stored on insulation rather than directly on the roof deck, which can get very hot. The insulation can also be used to shield the product from the sun.
- Keep only the materials that are planned to be used on that day on the roof.
- If products have been stored above or below the ideal temperature range, allow them to return to ambient room temperature before use to maintain expected coverage rates and performance.
How warmer temperatures affect adhesive properties
As temperatures rise, there will be noticeable changes in the flow properties of adhesives. Adhesives become less viscous—thinner and quicker flowing—which can lead to over-spreading and inconsistent coverage and can affect performance.
To minimize these issues, keep products in a protected and cool area, out of direct sunlight.
In excessive heat situations, reduce the installation area before mating materials.
Always follow the guidance in the technical data sheet for your specific product.
How warmer temperatures affect adhesive cure-times
Adhesive cure time—the period required for a full, reliable bond—is strongly influenced by outside air temperature. Heat speeds up the chemical reaction, meaning the product will cure quicker.
Higher temperatures can also decrease the open-time of adhesives, meaning there will be less working time and less time to position materials correctly. Please be mindful to adjust working times accordingly.
To ensure proper curing:
- Apply products during cooler parts of the day whenever possible.
- Always follow the guidance in the technical data sheet for your specific product.
How to prepare surfaces in summer
With rain still expected over summer months, products should only be applied in dry conditions.
Before applying any adhesive:
- Ensure the substrate is completely dry, clean, and free of contaminants.
- Confirm weather conditions will remain dry throughout the bonding and curing/drying periods.
Summer roofing doesn’t have to mean compromise
With the right storage, preparation, and application, contractors can work efficiently and confidently during summer months. Plan ahead, follow temperature specific guidelines, and adjust working times accordingly.
