Which of the following will NOT cause the adhesive strips of newly-installed shingles to fail to bond?

The phenomenon of adhesive strips failing to bond in newly-installed shingles can be influenced by various environmental factors. High temperatures can help the adhesives soften and bond effectively, while cold temperatures may prevent adehesive from adhering properly due to increased viscosity. Humidity usually promotes adhesion by providing moisture that activates the adhesives.

However, the option regarding an excessive amount of filler specifically refers to the material that may be used during the installation process. While an improper application or excess of filler could affect the overall integrity of a roofing system, it does not inherently affect the bond of the adhesive strips in the same way temperature or humidity does.

In essence, excessive filler may not directly interfere with the adhesive properties, which is why it is identified as the option that will not cause the adhesive strips to fail to bond. Understanding these factors helps in assessing the conditions that must be met for a successful installation of roofing materials.
