1. A roofing contractor is replacing an existing asphalt-shingle roof. During
tear-off, the contractor discovers deteriorated roof decking that is
structurally inadequate to support the new roofing system. What is the
most appropriate action?
A. Install new shingles over the deteriorated decking
B. Cover the damaged decking with underlayment
C. Replace or properly repair the deficient decking before installing the roof
covering
D. Install heavier shingles to stabilize the decking
Answer: C. Replace or properly repair the deficient decking before installing the
roof covering
Rationale: The roof deck is a structural substrate. Roofing materials should not
be used as a substitute for correcting structurally inadequate decking.
2. Which condition presents the greatest immediate concern when a roofing
contractor evaluates a low-slope roof before applying a new membrane?
A. Slight color fading
B. Inadequate drainage and ponding water
,C. Minor granule loss
D. Slightly uneven flashing paint
Answer: B. Inadequate drainage and ponding water
Rationale: Persistent ponding can accelerate membrane deterioration, increase
structural loading, promote leaks, and shorten roof-system service life.
3. On an asphalt-shingle roof, the primary purpose of properly installed
underlayment is to:
A. Replace the roof covering
B. Provide secondary protection against water intrusion
C. Increase attic ventilation
D. Provide structural support for rafters
Answer: B. Provide secondary protection against water intrusion
Rationale: Underlayment serves as a secondary water-shedding layer beneath
the roof covering and is particularly important at vulnerable areas.
4. A contractor is installing asphalt shingles on a roof with a slope below the
manufacturer's minimum slope requirement. What should the contractor
do?
A. Reduce nail spacing
B. Use more roofing cement
C. Follow an approved low-slope roofing method or select a suitable roofing
system
D. Install the shingles normally because slope does not affect performance
Answer: C. Follow an approved low-slope roofing method or select a suitable
roofing system
Rationale: Shingle systems have specific slope limitations. Using a conventional
shingle installation outside its approved application can cause water intrusion
and violate code or manufacturer requirements.
, 5. What is the principal function of step flashing where a sloped roof
intersects a vertical wall?
A. Increase attic ventilation
B. Provide a layered water-shedding transition between the roof and wall
C. Support the wall framing
D. Replace wall weather-resistive barriers
Answer: B. Provide a layered water-shedding transition between the roof and
wall
Rationale: Step flashing uses overlapping pieces integrated with the roofing and
wall system to direct water away from the intersection.
6. A roofing contractor finds that existing chimney flashing is improperly
integrated with the roof covering. What is the best approach when
reroofing?
A. Leave the flashing untouched
B. Cover the flashing with shingles
C. Correct or replace deficient flashing as part of the roof-system installation
D. Paint the flashing with roof coating
Answer: C. Correct or replace deficient flashing as part of the roof-system
installation
Rationale: Flashing is a critical water-management component. Defective
flashing can cause leaks even when the roof covering itself is properly installed.
7. What is the primary purpose of roof ventilation?
A. Increase indoor humidity
B. Reduce heat and moisture accumulation in the attic or roof assembly
C. Eliminate the need for insulation
D. Replace waterproof underlayment
Answer: B. Reduce heat and moisture accumulation in the attic or roof assembly
, Rationale: Proper ventilation helps control moisture and temperature conditions
within the roof assembly when designed as part of a balanced system.
8. Which condition most strongly indicates inadequate attic ventilation?
A. Properly distributed intake and exhaust ventilation
B. Condensation and moisture staining on roof framing
C. New architectural shingles
D. Copper flashing
Answer: B. Condensation and moisture staining on roof framing
Rationale: Excess moisture in an attic can result from inadequate ventilation, air
leakage, insufficient vapor control, or building moisture sources.
9. When installing roofing materials in cold weather, the contractor should
primarily:
A. Ignore manufacturer requirements
B. Follow the manufacturer's temperature and installation limitations
C. Increase nail length indefinitely
D. Eliminate all underlayment
Answer: B. Follow the manufacturer's temperature and installation limitations
Rationale: Adhesion, seal-strip activation, membrane flexibility, and material
handling can be significantly affected by temperature.
10.A roofing contractor installs shingles but fails to provide the required
starter course. What is the most likely consequence?
A. Improved drainage
B. Increased wind resistance
C. Improper sealing and increased vulnerability at the eave
D. Increased attic ventilation
Answer: C. Improper sealing and increased vulnerability at the eave
