1According to the Minnesota Residential Code, what is the minimum slope required for asphalt shingles on a residential roof?
A.2:12
B.3:12
C.4:12
D.1:12
Explanation: The Minnesota Residential Code requires a minimum slope of 2:12 for asphalt shingles, provided double underlayment is installed from eave to ridge. At slopes of 4:12 or greater, standard single-layer underlayment is permitted.
2Under Minnesota DLI rules, what is the minimum passing score required for the Residential Roofer licensing exam?
A.70%
B.75%
C.80%
D.65%
Explanation: The Minnesota Department of Labor and Industry requires a minimum score of 70% on the Residential Roofer exam. The exam consists of 110 questions and candidates have 5.5 hours to complete it.
3According to the Minnesota Residential Code, what is the maximum exposure for 3-tab asphalt shingles rated for normal wind conditions?
A.5 inches
B.5-5/8 inches
C.6 inches
D.4-1/2 inches
Explanation: Standard 3-tab asphalt shingles (12 inches wide) are typically installed with a maximum exposure of 5 inches. This allows for adequate head lap to maintain weather protection at each course.
4In Minnesota, ice barrier underlayment is required at eaves. How far up from the eave edge must the ice barrier extend?
A.At least 24 inches past the interior face of the exterior wall
B.At least 12 inches past the interior face of the exterior wall
C.At least 36 inches past the interior face of the exterior wall
D.To the ridge of the roof
Explanation: The Minnesota Residential Code requires ice barrier (ice and water shield) to extend from the eave edge to at least 24 inches past the interior face of the exterior wall. This protects against ice dam leakage that is common in Minnesota's cold climate.
5OSHA requires fall protection for residential roofing work at what height above a lower level?
A.6 feet
B.4 feet
C.10 feet
D.8 feet
Explanation: OSHA's residential fall protection standard (29 CFR 1926 Subpart M) requires fall protection at heights of 6 feet or more above a lower level. This applies to all residential construction activities including roofing.
6Under the Minnesota Residential Code, what is the minimum headlap required for asphalt shingles on roof slopes of 4:12 or greater?
A.2 inches
B.3 inches
C.4 inches
D.1 inch
Explanation: For asphalt shingles installed on slopes of 4:12 or greater, the Minnesota Residential Code requires a minimum headlap of 2 inches. This overlap ensures adequate water shedding at each shingle course.
7What is the primary purpose of roof ventilation as required by the Minnesota Residential Code?
A.To remove excess moisture and heat from the attic space
B.To provide fresh air to living spaces below the attic
C.To reduce wind uplift pressure on the roof
D.To comply with fire code requirements for smoke exhaust
Explanation: The primary purpose of roof ventilation under the Minnesota Residential Code is to remove excess moisture and heat from the attic space. In Minnesota's cold climate, proper ventilation helps prevent ice dams by keeping the roof deck cold and reduces moisture-related damage to framing and insulation.
8According to the Minnesota Residential Code, what is the minimum net free ventilation area ratio for attic spaces?
A.1/150 of the attic floor area
B.1/300 of the attic floor area
C.1/100 of the attic floor area
D.1/200 of the attic floor area
Explanation: The Minnesota Residential Code requires a minimum net free ventilation area of 1/150 of the attic floor area. This may be reduced to 1/300 when specific conditions are met, such as having a Class I or II vapor retarder on the warm side and balanced ventilation between upper and lower openings.
9Under Minnesota statute, which entity administers the Residential Roofer license exam?
A.Minnesota Department of Labor and Industry (DLI)
B.Minnesota Board of Architecture
C.PSI Testing
D.Minnesota Department of Commerce
Explanation: The Minnesota Department of Labor and Industry (DLI) administers the Residential Roofer licensing exam. DLI oversees the residential building contractor licensing program including roofers, and the exam is state-administered rather than through a third-party testing service.
10What type of underlayment does the Minnesota Residential Code require in valleys?
A.Ice barrier (self-adhering polymer-modified bitumen)
B.Standard #15 asphalt-saturated felt
C.Synthetic underlayment only
D.No underlayment is required in valleys
Explanation: The Minnesota Residential Code requires ice barrier (self-adhering polymer-modified bitumen sheet) in valleys. Valleys concentrate water flow and are particularly vulnerable to ice dam leakage in Minnesota's climate, making ice barrier protection critical.
