  9. 8. Due to the possibility of corrosion problems, what materials can be used as flashing when contact with masonry surfaces is a possibility and what should be avoided. (Page 4.5 - Section 3.2.0)? Answer Galvanized sheet metal, synthetic materials, occasionally copper, or stainless steel. Aluminum should not be used.

  14. 13. What type of nail is commonly used to fasten cornice members which are exposed to weather Page 4.13 - Section 4.1.0) Answer Hot-dipped Galvanized.

  15. 14. Calculate the number of squares of 1” × 8” drop siding (to the nearest square) required for a hip roof structure that is 50' long and 20' wide with 10' high walls, fifteen 3' × 5' windows, one 8' × 7' garage door, and two 8' × 7' sliding doors (Assume a 16% waste allowance, hint: 1 square = 100 square feet) (Page 4.20, 21 - Section 5.1.0). Answer (2(50’ X 10’) + 2(20’X10’))-(15(3’X5’)+(8’X7’)+2(8’X7’)) then take 16% of that answer and add to it for waste allowance. Divide the answer by 100 square feet to equal the number of squares needed. Result: (1007 Sq. Ft. +161.12 Sq. Ft. waste allowance)/100Sq. Ft. = 11.6812 or 12 squares of siding.

  16. 15. Calculate the number of 4' × 8' panels of vertical siding (to the nearest panel) required for a hip roof structure that is 50' long and 20' wide with 10' high walls, fifteen 3' × 5' windows, one 8' × 7' garage door, and two 8' × 7' sliding doors (Page 4.20, 21 - Section 5.1.0 see note on page 4.20). Answer (2(50’ X 10’) + 2(20’X10’))-((8’X7’)+2(8’X7’)) take no waste allowance. Divide the answer by 100 square feet to equal the number of squares needed. Result: (1232 Sq. Ft.)/32 Sq Ft. per panel = 38.5 or 39 4’ X 8’ panels

  19. What type of siding may need to be electrically grounded according to local building code (Page 4.22 - Section 7.13.1)? Answer Steel or aluminum siding

  20. 19. What is the main reason for installing a furring strip under the first course of beveled wood siding (Page 4.23 - Section 5.2.1 see Note section)? Answer This allows the siding to project (outward) the same distance as the course above.
