Roof flashing is a thin material, usually galvanized steel, that professional roofers use to direct water away from critical areas of the roof, wherever the roof plane meets a vertical surface like a wall or a dormer. Flashing is installed to surround roof features, such as vents, chimneys, and skylights. Water should run down the side of the flashing and be directed to the shingles instead of finding its way into the roof deck.
Ridge vents and turbines
A turbine is installed directly on the top of a roof and uses wind power to suck hot and humid air out of the attic. A turbine has a series of vanes that spin as the wind passes through them.
A ridge vent runs across the top of the roof’s peak. Unlike turbines, this venting style does not have any moving parts. A ridge vent is similar to a screen and allows heat to escape up and out of the attic.
Pre-formed flange placed over a vent pipe to seal the roof around the vent pipe opening. Made of lead, rubber, or metal. Referred to by various terms {pipe boot/jack, plumbing boot/jack, and/or no-caulk or leads}.

Slant-back Roof Louvers are a type of attic exhaust vent that make up half of a balanced attic ventilation system for each roof. Intake vents make up the other half of the system. Together they help remove any built-up heat and moisture inside the attic for year-round ventilation.
