Run the vent continuously from ridge end to ridge end and keep it low-profile so shingles lay flat over the Posi-tabs. Never mix competing exhaust types on one roof plane, as that can short-circuit airflow.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eCutting and nailing along the ridge requires working at height; follow ladder and fall-safety practices and local building codes for attic ventilation ratios.\u003c\/em\u003e\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003eUpgrade attic exhaust with the Lomanco PRO4-N OmniRidge Vent, 18 sq. in.
