studs doubled?
5. 5/8 inch: A solid plywood roof deck at 3/12 pitch or greater, receiving asphalt
shingles and having rafters laid out 24 inches on center, should have a minimum
plywood sheathing thickness of .
6. OSB with edge nailing 4" o.c. and field 6 "o.c.: Specific information about shear
walls, such a type of sheathing and nailing, can usually be found on the building
plans. Abbreviations such as "6W4" are common, which would mean:
7. S-GRN: "Surfaced Green" Not dried, moisture content over 19%.S-DRY:
"Surfaced Dry" Air dried to a moisture content less than 19%. KD: "Kiln Dry"
Dried in a heated kiln to a moisture content less than 19%.MC 15: "Moisture
Content 15%" Dried to a moisture content of 15% or less.HT: "Heat Treated"
Heated to at least 133° Fahrenheit for 30 minutes at the board's core to kill
any insects present in the wood.: Graded lumber is marked with an indication of
moisture content; which is the driest designation?
8. To shed water away from the structure at roof to wall transitions
(Step flashing are interwoven between each course of shingles and protect the
transition from water intrusion by creating a water shed aka shingle effect.

9. A) Will always be parallel: Bracing lines:
A) Will always be parallel
B) Should intersect at 90Ú
C) Always run in the same direction
D) Can be added at any time
10. D) Weave shingles under the lower end of the base flashing and over the
upper portion of the base flashing
(In re-roof overlays, many roofers will conceal the base flashing under the
shingles and apply mastic at the transition. While this method is allowable for
overlays, it is not recommended due to the inherent likelihood of moisture

deck, it may be necessary to use blocking between joists.
A) Blocking is required at the beginning of any overhang
B) Blocking is required every 10 feet
C) Blocking is required if joists are 24" o.c. or more
D) Blocking is required if joists are 8"x or larger
14. 24" o. c.: What is the maximum spacing of 2 x 4 inch studs on a 1 story house?

18. 14': What is the maximum height for a laterally unsupported 2 x 4 inch nonbear-
ing wall stud?
19. D) Interrupt ceiling membrane for fire-resistance
(Fire resistance is required between the first and second story of a building
and this can be achieved by using a 1-hr or 2-hr fire-resistant ceiling mem-
brane. However, doubling up on a top plate allows for interruptions of the
ceiling membrane assuming X-type gypsum wallboard is used and that all
penetrating items through the double top plate are protected.
Among other things, the top plate is doubled to maintain tension continuity
for lateral loads.): Why do you need to double-up on a top plate?
