1In roofing estimating, one square of roof covering is equal to which area?
A.10 square feet
B.50 square feet
C.100 square feet
D.144 square feet
Explanation: A roofing square is 100 square feet of roof surface. Estimators convert measured roof area to squares, then add waste and convert to bundles or rolls. Using any other unit as a 'square' will throw off material takeoffs and bids.
2Most standard asphalt strip and laminated shingles are packaged so that how many bundles cover one square?
A.2 bundles
B.3 bundles
C.4 bundles
D.5 bundles
Explanation: Typical three-tab and laminated asphalt shingles are sold three bundles to the square, so each bundle covers about 33.3 square feet. Always confirm the wrapper, because some designer, luxury, or metric products use four or more bundles per square.
3IRC 2021 Section R905.2.4 requires asphalt shingles to comply with which material standard?
A.ASTM D226
B.ASTM D1970
C.ASTM D3462
D.ASTM E108
Explanation: IRC R905.2.4 states that asphalt shingles shall comply with ASTM D3462. That specification covers fiberglass-mat asphalt shingles used on steep-slope residential roofs. Other ASTM numbers in Chapter 9 address underlayment, ice-barrier sheets, or fire tests, not the shingle itself.
4What is the minimum roof slope on which IRC 2021 permits asphalt shingles?
A.1 unit vertical in 12 units horizontal (1:12)
B.2 units vertical in 12 units horizontal (2:12)
C.3 units vertical in 12 units horizontal (3:12)
D.4 units vertical in 12 units horizontal (4:12)
Explanation: IRC R905.2.2 allows asphalt shingles only on slopes of 2:12 or greater. Below 2:12, water does not shed reliably from a shingled surface and a low-slope membrane system is required. Slopes from 2:12 up to 4:12 also require double underlayment.
5Where an ice barrier is required, IRC 2021 Section R905.1.2 says it must extend from the lowest roof edges to a point not less than how far inside the exterior wall line?
A.12 inches
B.18 inches
C.24 inches
D.36 inches, measured only along the eave
Explanation: The ice barrier must reach at least 24 inches inside the exterior wall line so it sits over the warm interior, not just the soffit. That location is where ice dams typically force meltwater back under the covering. On slopes of 8:12 or greater, the barrier must also run at least 36 inches up the roof slope from the eave edge.
6Self-adhering polymer-modified bitumen underlayment used as an ice barrier must be labeled to which standard?
A.ASTM D226 Type I
B.ASTM D1970
C.ASTM D4869 Type I
D.ASTM D6757
Explanation: IRC R905.1.1 and R905.1.2 recognize self-adhering polymer-modified bitumen sheet labeled to ASTM D1970 as an ice-barrier and alternative underlayment. Felt products are D226 or D4869; D6757 is another underlayment listing, not the ice-barrier membrane standard.
7Where Class A, B, or C roofing is required, IRC 2021 Section R902.1 says the covering shall be tested in accordance with which standards?
A.ASTM D7158 or ASTM D3161
B.ASTM E108 or UL 790
C.ASTM D3462 or ASTM D3909
D.UL 2218 or FM 4473
Explanation: Fire classification of roof coverings is determined by ASTM E108 or UL 790. Class A, B, or C roofing is required in jurisdictions that mandate it or where the roof edge is less than 3 feet from a lot line. Wind and impact tests are separate listings.
8Using common estimating coverage, one roll of No. 15 (ASTM D226 Type I) asphalt felt is taken off as covering how many squares?
A.1 square
B.2 squares
C.4 squares
D.10 squares
Explanation: A standard roll of No. 15 felt is 36 inches by 144 feet, or 432 square feet, which estimators treat as 4 squares of coverage. No. 30 felt is typically taken off at 2 squares per roll. Always add lap and waste; the 4-square figure is the catalog coverage, not net after laps on a steep roof.
9IRC 2021 Section R904.2 requires roof-assembly materials to be:
A.The lowest-cost products available at the supplier
B.Compatible with each other and with the building to which they are applied
C.All from the same manufacturer, regardless of listing
D.Unlabeled bulk materials so they can be mixed on site
Explanation: R904.2 requires roof-assembly materials to be compatible with each other and with the building. Incompatible felts, solvents, sealants, or metals can dissolve coatings, corrode flashings, or void listings. R904.4 separately requires packaged materials to bear the manufacturer's marks and required testing-agency labels.
10On an asphalt-shingle roof with a 3:12 slope in an area where wind design is not required, how must underlayment be applied?
A.One layer lapped 2 inches, shingle fashion from the eave
B.Two layers: a 19-inch eave starter strip, then 36-inch sheets overlapping 19 inches
C.No underlayment is required below 4:12
D.One layer of 30-pound felt set vertically from rake to rake
Explanation: For asphalt shingles on slopes from 2:12 up to 4:12, IRC Table R905.1.1(2) requires two layers of underlayment. A 19-inch strip starts at the eave, then 36-inch sheets overlap 19 inches so the deck has double coverage. End laps are 4 inches and offset 6 feet. Single-layer, 2-inch side laps are allowed only at 4:12 and steeper in non-wind-design areas.
