The most versatile multi-purpose ridge vent in the industry

The Ridgeline® Ridge Vent System eliminates moisture, reduces energy costs, and increases the life of your roof. Ridgeline® can be installed in conjunction with shingles or shakes as well as Ondura® and Onduvilla.


Low profile Ridgeline® vents are highly effective, yet practically invisible. They achieve balanced air flow that other types of vents just cannot deliver. Plus, unlike most ridge vent systems, Ridgeline® has no filters to clog, so it never loses efficiency.  Hot air building up in the attic of your home can be a destructive force. You do not have to destroy the looks of your roof to get an even flow of fresh air.


Simply install the Ridgeline® Ridge Vent! Unlike unsightly aluminum ridge vents or old-fashioned roof and turbine vents, a Ridgeline®Ridge Vent can barely be seen. Nailed securely in place beneath roofing, a Ridgeline® vent raises the ridgecap only ¾”.

Why Use Ridgeline

Low-profile Ridgeline works great on roofs of all types and styles.
  • Conventional concealed ridge installation.
  • Installed on Ondura© corrugated roofing tile.
  • Installed on Cedar Shake Applications.
Convenient snap-out baffles enable Ridgeline to easily adapt to a variety of applications.
  • Peak vent application for roofs of contemporary design.
  • May be used to tie in where a roof and wall join.
  • May even be used as an intake vent when soffit ventilation isn’t possible.
Ridgeline. The best choice in ridgevents.
  • Ridgeline features a unique roll style peak which eliminates shingle cracking at the ridgecap.
  • Ridgeline’s interior baffle system won’t clog with debris and snow like exterior baffles found on many other ridge vents.
  • And, Ridgeline vents are completely covered with roofing, so there’s no chance of deterioration from damaging UV rays.
Warranty SupportMost shingle warranties required ventilation. Ridgeline vents provide 15 square inches per linear feet of net free ventilation when used in conjunction with balanced soffit ventilation.

Why is Ridgeline more effective than other types of vents?

Continuous air flow is assured with a Ridgeline Ridge Vent. Unlike many other ridge vents, Ridgeline Ridge Vent doesn’t contain filters that can become clogged, causing it to lose its efficiency. Turbine vents, including expensive power vents, provide air circulation in a confined area only. Gable vents leave much of the roof unventilated. Hood (or scoop) vents rely on atmospheric pressure for air movement, resulting in inadequate ventilation–even with proper soffit ventilation.


Which type of closures are used when installing Ridgeline in conjunction with an Ondura roof?

Solid closures are used at the peak of the roof, and ventilated closures are used at the eave portions.


Can I use Ridgline Ridge Vents with shingle or cedar shake roofs?

Absolutely; Ridgeline is effective on shingle, cedar shake and Ondura roofs.


How does the Ridgeline Ridge Vent System work?

To operate effectively, Ridgeline vents use two natural forces–thermal air flow and air pressure. These forces, in combination and separately, allow a uniform stream of air to flow across all inner roof deck surfaces and out of the attic. This results in balanced flow–something that gable and other venting methods can’t achieve. Your attic remains dry, because moisture is constantly being evaporated. And, instead of “spot venting,” fresh air circulates in all areas of the attic, prolonging the life of roofing materials.
