Boral Ridge Vent Installation Nationwide

Boral Ridge Vent Installation: The Los Angeles Owner’s Guide

Most Boral ridge vent installations in Los Angeles run $850 – $1,400 for a full replacement, and we stock Boral-compatible ridge vent components on every truck. Dylan Pace and our crew can typically inspect, match, and install same-day if we catch it before afternoon dispatch. Homeowners usually spot trouble after a Santa Ana wind event or the first heavy winter rain – water stains on the ceiling near the peak, or granules collecting in the gutters that trace back to lifted vent sections.

Which Boral Models This Applies To

Boral’s ridge vent systems in Los Angeles fall into two main lines: the Boral Stone-Coated Steel systems (often paired with their concrete and steel shake or tile profiles) and the Boral concrete tile ridge assemblies used on Spanish Revival and Mediterranean-style homes from Pasadena to the Westside. The critical match point isn’t just the vent profile – it’s the batten height and tile exposure. Stone-coated steel uses a lower 1.5-inch batten; concrete tile needs 2.5 to 3 inches to clear the profile.

Check the underside of your existing vent for a stamped date code and part prefix – Boral vents typically carry a “BRV-” or “SCS-” series mark. If your roof was installed between 2005 and 2015, you may have the older Boral rigid vent with integrated end caps; current production uses a flexible mesh design that adapts better to the thermal expansion Los Angeles roofs endure. We carry both OEM Boral and a quality aftermarket equivalent, Lomanco’s OmniRoll, which matches the airflow spec (12 square inches per linear foot of NFA) and carries the same 20-year material warranty. Every promise in writing – that’s just how we do it.

Signs Your Boral Ridge Vent Installation Is Failing

• Water staining on the ceiling directly below the roof peak. The ridge vent sits at the highest stress point for wind-driven rain. In Los Angeles, the combination of dry summer heat hardening the butyl sealant, followed by winter storms hitting at 30-plus mph, forces water through gaps that opened during thermal cycling.
• Granules or small debris washing out from under the vent cap. This means the fasteners backing out or the vent lifting off the ridge board. On Boral stone-coated systems, the concealed fastener clips corrode faster than the steel itself, especially within three miles of the coast where salt air accelerates the process.
• Hot, stagnant attic air even with the vent visually intact. The internal baffle or mesh has collapsed or clogged. Boral’s earlier rigid designs used a plastic matrix that degrades in UV after 12 – 15 years – right in the window for many Los Angeles installations.
• Visible daylight through the vent from inside the attic. End caps have separated or the vent was cut short during original installation, leaving a gap. This is common on hip roofs where multiple angles meet; the miter cuts are precise and often botched by crews rushing the finish.
• Sections of the vent cap lifting or “oil-canning” in wind. The metal has fatigued from expansion and contraction. In the San Fernando Valley, where daily temperature swings hit 40 degrees, we’ve seen this on Boral systems as young as eight years old.

Replacement Cost & What’s Included

What drives the range: accessibility (steep pitches or two-story homes in the Hollywood Hills add labor), whether we need to remove and reset Boral tile or stone-coated panels to access the vent, and if the underlying ridge board has rot. Our written quote itemizes each line – material, labor, disposal, any deck repair – before you approve anything. The 365-Day Done Right Promise covers the installation; manufacturer defects on the vent itself are handled through Boral’s warranty channel, which we facilitate. We pull permits when required by your local Los Angeles jurisdiction, and inspections are included in our price.

DIY or Call Us?

There’s one thing you can safely check yourself: from the ground or a secure ladder, look for lifted sections, missing end caps, or daylight gaps. Take photos. That’s it.

Everything past that belongs to a crew with fall protection and roofing-specific liability coverage. Walking a ridge line – the highest, most exposed point of the roof – is where most homeowner injuries happen. Removing Boral tile or stone-coated panels without cracking them requires knowing the lock pattern and fastener spacing. And here’s the gotcha: if you disturb the vent and don’t reseal it properly, you’ve just voided any remaining warranty and created a leak path that may not show for months. We answer calls live at (325) 246-5075, send you a trackable arrival window, and show you before-and-after photos before we leave. The estimate is free.
