Correct Answer: E. Louisiana 7-803 Residential Roofing Contractor License
EXPERT RATIONALE: Louisiana law requires that any contractor performing
residential roofing work hold a specific 7-803 Residential Roofing Contractor
License issued by the Louisiana State Licensing Board for Contractors (LSLBC). This
ensures the contractor meets the competency and insurance standards specific to
residential roofing.
,2. What is the minimum slope generally required for asphalt shingles to be
installed per standard roofing practice?
A. 1:12
B. 1.5:12
C. 2:12
D. 3:12
E. 4:12
Correct Answer: C. 2:12
EXPERT RATIONALE: Standard asphalt shingle installation requires a minimum
roof slope of 2:12 (2 inches of rise for every 12 inches of horizontal run). Below this
slope, special low-slope techniques or different materials must be used to prevent
water infiltration.
3. Which organization publishes the widely used asphalt shingle installation
standards referenced in residential roofing?
A. OSHA
B. EPA
C. ARMA (Asphalt Roofing Manufacturers Association)
D. NRCA (National Roofing Contractors Association)
E. ICC (International Code Council)
Correct Answer: C. ARMA (Asphalt Roofing Manufacturers Association)
EXPERT RATIONALE: ARMA publishes the technical guidelines and installation
standards for asphalt shingles. Roofing contractors rely on ARMA's
recommendations for proper installation methods, which are also referenced in
many building codes.
,4. In Louisiana, which entity is responsible for issuing residential roofing
contractor licenses?
A. Louisiana Department of Labor
B. Louisiana Office of Financial Institutions
C. Louisiana State Licensing Board for Contractors (LSLBC)
D. Louisiana Department of Insurance
E. Louisiana Real Estate Commission
Correct Answer: C. Louisiana State Licensing Board for Contractors (LSLBC)

B. Polyethylene sheeting
C. ASTM D226 Type I or Type II felt or approved synthetic underlayment
D. Tar paper rated for commercial use only
E. No underlayment is required
Correct Answer: C. ASTM D226 Type I or Type II felt or approved synthetic
underlayment
EXPERT RATIONALE: ASTM D226 felt underlayment (15 lb or 30 lb) or
equivalent approved synthetic underlayment is standard for residential roofing. It
provides a secondary water-resistant barrier beneath shingles, critical in Louisiana's
high-rainfall and hurricane-prone environment.
, 6. What is the standard nail penetration required into roof decking when
installing asphalt shingles?
A. ¼ inch
B. ½ inch
C. ¾ inch
D. 1 inch
E. 1½ inch
Correct Answer: C. ¾ inch
EXPERT RATIONALE: Proper fastening of asphalt shingles requires nails to
penetrate at least ¾ inch into the roof deck or completely through the sheathing.
Inadequate penetration leads to shingle blow-off, especially critical in Louisiana's
hurricane-risk zones.
7. What is the purpose of ice and water shield on a residential roof?
A. To add insulation value to the roof system
B. To act as a vapor barrier in the attic
C. To provide a waterproof membrane protecting against ice dams and wind-
driven rain
D. To reinforce the structural decking
E. To reflect UV radiation and reduce cooling costs
Correct Answer: C. To provide a waterproof membrane protecting against
ice dams and wind-driven rain
EXPERT RATIONALE: Ice and water shield is a self-adhering, waterproof
underlayment installed at eaves, valleys, and other vulnerable areas. It protects
against water intrusion caused by ice dams and wind-driven rain, which is especially
important in storm-prone Louisiana.
