Remove and dispose of existing roofing to bare wood sheathing. Install 30 squares of min. 235-lb. fiberglass asphalt shingles (min. 25-year warranty) with new 30-lb. felt (or equivalent synthetic) underlayment, galvanized drip edge, and mill-finish aluminum flashing. Assume a rectangular hip roof; custom flashing at two average-size skylights; and custom cap treatment at vented ridge.
