Two stories instead?
A two-story 2,000 sq ft house sits on about 1,000 sq ft, so its roof is 11.6–13.2 squares. That matches a 1,000 sq ft ranch. A 4,000 sq ft two-story has about the same roof as this one-story.

Attic vents. With about 2,000 sq ft of attic floor, the IRC R806.2 ratios work out to 1,920 sq in of net free vent area at 1/150 or 960 sq in at 1/300, about 480–960 sq in of it at the soffits. That balance keeps the deck cold and cuts ice dams.
Eave ice barrier. Assuming a rectangle 1.5 times as long as wide, a 2,000 sq ft ranch has about 115 ft of eaves. At 6/12 with a 12-inch overhang that is 2 courses (40.2 in up the slope), roughly 689 sq ft of membrane where your local code calls for it.
