Roof Size: 30 squares.
Slope: 4 in 12.
Valleys – about 80 ln. ft.
Roof Installation Includes:
Tear off existing roofing down to the wood decks.
Install new felt underlayment.

Install galvanized drip edge and mill-finish aluminum flashing.
The job includes about 5-squares of hip roof, custom flashing for two average-size skylights (these flashings are always provided by skylight manufacturers, so “custom” is a gimmick, and a premium vented ridge.
