VACATION/SICK DAYS: For your first 3 years of service you earn vacation at 4 hours per pay period (26 pay periods per year) for a total of 13 days. After 3 years of service you earn 6 hours per pay period and adjusted to total 20 days per year. After 15 years service you earn 8 hours per pay period or 26 days a year.
1 For a 2,000 square foot roof, this amounts to a total cost of around $10,000 to $60,000.  Concrete roof tile costs are generally around $5 to $10 per square foot, or $10,000 to $20,000 for a 2,000 square foot roof.
Note: many professional roofing contractors price their roofs on a per square basis, where one square is a 10 by 10 foot area or 100 square feet. Thus, your total cost in square terms could range from $350 to $1,200 per square of metal roofing installed. For comparison, most asphalt shingle roofs will cost anywhere from $300 to $700 per square installed depending on the material choice, roof complexity, installerâs credentials, your geographic area, time of the year, and so forth.
