Using incompatible adhesive with a roof system may result in:

Using incompatible adhesive with a roof system may indeed void the roof system's warranty because manufacturers typically specify certain products and materials that must be used in conjunction with their roofing systems. If an adhesive that is not approved or recommended by the manufacturer is used, it can lead to structural integrity issues or premature failure of the roofing system.

When a roofing system fails due to the use of incompatible materials, the manufacturer is usually not liable for repair or replacement costs, as this violates the terms and conditions of the warranty. This means that any damages that occur as a result of improper adhesive use would not be covered, ultimately leading to additional costs for the building owner. Therefore, it's crucial to adhere to the manufacturer's specifications to maintain the warranty and ensure the longevity and effectiveness of the roofing system.
