Illinois Roofing Practice Exam

Which statement most accurately describes low slope roofing systems?

1. NRCA recommends that all roofing systems be built underground

2. Low slope roofing systems work best in extremely high temperatures

3. NRCA recommends that cold storage and freezer building roofs work out best when the temperature structure is built within another building envelope closure

4. Low slope roofing systems are not suitable for any climate

The correct answer is: NRCA recommends that cold storage and freezer building roofs work out best when the temperature structure is built within another building envelope closure

The most accurate statement about low slope roofing systems is that cold storage and freezer building roofs work best when the temperature structure is built within another building envelope closure. This is because low slope roofing systems often require specialized insulation and vapor barriers to manage condensation and temperature control effectively. By placing the temperature sensitive areas within another building envelope, it's easier to maintain the optimal temperature required for cold storage and freezers, enhancing energy efficiency and preventing moisture accumulation. Low slope roofing systems typically do not do well in all climates; rather, they can be effectively utilized when designed properly and when specific considerations are made for the conditions in which they are used. Additionally, while low slope roofing systems can handle various temperature ranges, they do not necessarily perform best in extremely high temperatures, and underground installations are not a common recommendation for roofing systems by the NRCA.
