6. Roof framing and sheathing are included in the estimate for carpentry. Following are given the estimates for slating and miscellaneous roof items:
Slating
| Quantities | Squares |
| Main and dormer roofs | 22.0 |
| Porch roof | 6.4 |
| Tower roof | 3.7 |
| 32.1 |
Cost
The price of slating per square is given in [Table XII], Estimating and Calculating Quantities, Part 1. Bangor slating costs $8 per square. On account of the curved tower and the number of hips and valleys, and because the measurement just given is actual measurement, the price will be put at $10 per square. Thus, the cost of 32.1 squares at $10 will be $321.

LATHING AND PLASTERING
7. Plastering varies in price according to its position and quality. It is therefore necessary to make a separate schedule of each class of work, so that any increase or decrease in quantity may be easily added to or deducted from the estimate.
