What are two main disadvantages of Cutbacks in roofing?

The selection of Volatile Organic Compound (VOC) content and odor as the main disadvantages of cutback roofing materials is accurate because these factors significantly impact their environmental and user-friendliness. Cutback roofing products, often used in built-up roofing systems, contain high levels of VOCs. These compounds easily evaporate at room temperature, contributing to air pollution and potential health issues for those exposed to them during application. The strong odors associated with VOCs can also lead to discomfort for roofers and those nearby, complicating installation in occupied areas.

Moreover, cutback materials can create challenges for environmental compliance, as regulations regarding VOC emissions have become stricter over time. As the construction industry moves toward more sustainable practices, the presence of VOCs in roofing materials raises concerns about compliance with environmental standards.

Other options might highlight important aspects of cutback roofing, but they do not align as closely with the most pressing disadvantages faced in modern roofing applications. For instance, while issues like high cost, poor adhesion, viscosity, curing times, or compatibility with UV coatings are relevant, they are not as universally recognized as significant disadvantages when considering the broader environmental and safety implications posed by VOC emissions and odors.
