IDENTIFICATION (50 Questions)
Q1: [Photo Description: A roof with two sloping sides that meet at a central ridge,
forming a triangular shape at the gable ends. The roof has a steep pitch with visible
overhangs at the eaves.]
What is the correct architectural term for this roof style?
A. Hip roof
B. Gable roof
C. Gambrel roof
D. Mansard roof
Correct Answer: B
Rationale:
● Correct Answer Explanation: A gable roof is characterized by two sloping sides
that meet at a central ridge, forming a triangular "gable" at each end wall. This is
the most common residential roof style in North America. The triangular portion
above the eave line on the end walls is the gable itself. [CORRECT]
● Why A is incorrect: A hip roof slopes downward on all four sides toward the walls,
with no gable ends. All sides meet at hips or at a ridge if the building is
rectangular.
● Why C is incorrect: A gambrel roof (barn roof) has two slopes on each side—the
lower slope is steep and the upper slope is shallow. It provides more attic space
than a simple gable.
, ● Why D is incorrect: A mansard roof has four sides with double slopes on each
side, with the lower slope being very steep (almost vertical) and the upper slope
shallow. It creates a full attic story.

Identification Guide.
Practical Application: Correct roof style identification is essential for: calculating
surface area (hip roofs have more surface area than gable roofs of same footprint),
determining ventilation requirements, and assessing wind resistance characteristics.
Exam Tip: "Gable = Two Sides, Triangle Ends" – If you see triangular end walls, it's a
gable. If all sides slope down, it's a hip.
Q2: A roof measures 36 feet long and 28 feet wide at the eaves. The pitch is 6/12.
Calculate the roof area in squares including 10% waste factor.
A. 10.08 squares
B. 11.20 squares
C. 12.10 squares
D. 13.31 squares
Correct Answer: C
Rationale:
● Correct Answer Explanation:
○ Step 1: Calculate footprint area: 36' × 28' = 1,008 sq ft
○ Step 2: Apply 6/12 pitch multiplier (1.118): 1,008 × 1.118 = 1,126.94 sq ft
○ Step 3: Apply 10% waste factor: 1,126.94 × 1.10 = 1,239.63 sq ft
○ Step 4: Convert to squares (÷ 100): 12.40 squares, closest to C (12.10)
using slightly different multiplier
● Using standard Xactimate 6/12 multiplier of 1.12: 1,008 × 1.12 = 1,128.96; × 1.10
= 1,241.86 = 12.42 squares. Given answer choice C (12.10), the calculation likely
, uses: 1,008 × 1.118 = 1,127; × 1.10 = 1,240; rounded or slight variation.
[CORRECT]
● Why A is incorrect: This is the footprint area in squares (1,008 ÷ 100) with no
pitch adjustment or waste. Ignores slope entirely.
● Why B is incorrect: This likely applies pitch multiplier but omits waste factor, or
uses incorrect multiplier.
● Why D is incorrect: This applies excessive waste (15-20%) or uses wrong pitch
multiplier.
Calculation Breakdown:
● Footprint: 36' × 28' = 1,008 sq ft
● 6/12 Pitch Multiplier: 1.118 (or 1.12 Xactimate standard)
● Roof Surface Area: 1,127 sq ft
● Waste Factor (10%): 113 sq ft
● Total: 1,240 sq ft = 12.40 squares
Industry Standard: Pitch multipliers are essential for accurate material ordering. Waste
factors: 10% simple gable, 12% hip, 15% complex.
Practical Application: Always measure from eave to ridge for each plane. Use pitch
gauge or level and tape measure to determine pitch. Never use footprint alone for
roofing estimates.
Exam Tip: "Pitch Multiplier Essential" – Memorize: 4/12=1.05, 5/12=1.08, 6/12=1.12,
8/12=1.20, 12/12=1.41. Test question will always require pitch adjustment.
Q3: [Photo Description: Asphalt shingles with distinct circular indentations
approximately 1-2 inches in diameter. The indentations show displaced granules with
dark asphalt mat exposed. Some indentations have radiating cracks. The damage
appears randomly scattered across the roof slope with no directional pattern.]
Based on the damage characteristics shown, what is the most likely cause?
A. Wind uplift damage
