What roofing system minimizes health risks for hospital patients?

The correct choice is EPDM (Ethylene Propylene Diene Monomer) roofing, which is known for various health and safety benefits particularly relevant to hospital environments. EPDM is a type of synthetic rubber roofing that has a range of advantages including being lightweight, having a low environmental impact, and being resistant to UV radiation and ozone degradation.

In scenarios involving hospitals, where patient safety is paramount, EPDM roofing systems are preferable because they do not off-gas harmful chemicals or volatile organic compounds (VOCs) once installed. This is crucial in minimizing any indoor air quality issues that could affect sensitive populations, such as patients with respiratory conditions. Additionally, EPDM has excellent waterproofing qualities, which helps prevent leaks that could lead to mold growth—a major health concern in healthcare facilities.

Moreover, this roofing system is also energy-efficient, which can contribute to a better indoor environment. Its reflective properties can help in reducing heat absorption, thereby promoting a more stable temperature within the building, which is beneficial for patient comfort and contributes to overall health and safety in the hospital setting.

In contrast, the other roofing options may have drawbacks that could impact health and safety. For example, asphalt and wooden shingles may pose risks of VOC emissions and are less effective at preventing
