1. NYC Health + Hospitals uses a Civil Service examination system for many
non-managerial positions, with candidates placed on eligible lists after
passing applicable examinations.
Below is a practice examination for the NYC Health + Hospitals Senior
Roofer Examination.
1. A Senior Roofer working at a NYC Health + Hospitals facility is assigned
to inspect a large built-up roofing system that has developed several leaks.
Before beginning repairs, what should be the first step in a professional
assessment?
A. Immediately remove all roofing materials around the suspected leak area
B. Apply a temporary coating over the entire roof surface
,C. Identify the source of water intrusion by examining roof components,
flashing, drainage, and interior damage patterns
D. Replace the entire roofing system regardless of the condition
Answer: C. Identify the source of water intrusion by examining roof
components, flashing, drainage, and interior damage patterns
A proper roof repair begins with accurate diagnosis. Water leaks often
travel away from their entry point, so Senior Roofers must inspect
membranes, flashings, penetrations, drainage systems, and related
components before selecting a repair method.
2. When installing an asphalt shingle roof, the primary purpose of the
underlayment beneath the shingles is to:
A. Increase the color appearance of the roof
B. Provide an additional moisture barrier and protect the roof deck
C. Replace the need for proper flashing
D. Eliminate the need for roof ventilation
Answer: B. Provide an additional moisture barrier and protect the roof
deck
Underlayment serves as a secondary weather-resistant layer that protects
the roof deck from moisture penetration, especially during wind-driven
rain or when shingles fail.
,3. A Senior Roofer supervising a crew notices that workers are installing
roofing materials during strong winds. What is the most appropriate safety
action?
A. Allow work to continue if workers are experienced
B. Increase the number of workers on the roof
C. Stop unsafe operations and evaluate whether conditions allow safe
continuation
D. Remove all safety equipment because it may interfere with movement
Answer: C. Stop unsafe operations and evaluate whether conditions allow
safe continuation
Senior Roofers have supervisory responsibility for maintaining safe work
practices. Wind, weather conditions, and unstable materials can create
serious fall and equipment hazards.
4. In a low-slope roofing system, ponding water is a concern because it can:
A. Improve membrane durability
B. Increase roof lifespan
C. Accelerate deterioration and contribute to leaks
D. Strengthen roof insulation
Answer: C. Accelerate deterioration and contribute to leaks
, Standing water places additional stress on roofing materials, may degrade
membranes, and can eventually lead to leaks, structural concerns, and
premature roof failure.
5. The main purpose of roof flashing around pipes, vents, walls, and other
penetrations is to:
A. Improve roof appearance only
B. Prevent water from entering vulnerable areas
C. Increase roof weight
D. Replace roof insulation
Answer: B. Prevent water from entering vulnerable areas
Flashing directs water away from openings and transitions where roofing
materials meet other structures. Proper flashing installation is essential for
preventing leaks.
6. A Senior Roofer is selecting a repair method for a damaged single-ply
membrane roof. Which factor is most important when determining the
correct repair?
A. The roof color preference
B. Compatibility of repair materials with the existing membrane
