Boral Ridge Vent Installation: The Ventura Owner’s Guide
We stock and install Boral-compatible ridge vent systems across Ventura, with most complete ridge vent installations running between $650 and $1,400 depending on roof length and existing decking condition. If your ridge vent is cracked, lifting, or leaking during winter rains, we can typically get a crew out within a few days with the right parts already on the truck. Most Ventura homeowners discover the problem after a heavy storm, when water stains show up on ceiling drywall near the peak, or when they spot daylight coming through the ridge from inside the attic.
Which Boral Models This Applies To
Boral’s ridge vent line covers two primary profiles: the low-profile Boral Ridge Vent (typically 4 feet per section, 12 inches of exposed vent opening per piece) and the Boral Cedar Ridge Vent, which mimics a cedar shake profile for homes going for a more finished look. The low-profile version is the one we replace most often in Ventura because it’s been on hundreds of the older tile and composition roofs still standing in neighborhoods like Midtown and College Area.
One compatibility gotcha we see constantly: Boral ridge vents are designed to integrate with Boral’s own roofing systems, and the vent’s side flanges are cut to a specific profile that doesn’t always sit flush against non-Boral tiles. If you have a mix of original Boral tiles and newer replacement tiles from another manufacturer, the vent won’t seal cleanly at the transition points. We can tell you within the first five minutes whether your setup is compatible just by looking at the tile profile and the vent’s underside imprints.
For replacement, Boral-branded ridge vent sections are still available through roofing supply houses, but we also carry a high-quality aftermarket equivalent that matches Boral’s 12-inch vent opening and 4-foot section length. The aftermarket piece typically saves 20 to 30 percent on materials without sacrificing airflow or UV resistance, and we’ll show you both prices before we order anything.
Styles & brands we work with
Signs Your Boral Ridge Vent Installation Is Failing
- Water staining along the ceiling peak or upper walls. This is the most common failure signal in Ventura, and it means the vent’s weather seal or end caps have cracked and are letting rain through. The staining usually appears after the first heavy storm of the season, often in rooms that share the attic’s highest point.
- Visible cracks or warping on the vent plastic from the street or ladder. Boral’s rigid plastic vents are UV-stable, but anything installed for 15-plus years in direct Ventura sun will eventually get brittle. Hairline cracks near the nail line are the first stage of a vent that’s about to lift.
- Daylight visible through the ridge from inside the attic. If you can see light where the vent meets the roof deck, the vent has pulled away from the decking or the shingle overlap has failed. This gap is also where embers can get in during fire season, which matters a lot in the hills above Ventura.
- Granule buildup in gutters near the downspout corners. When ridge vent shingle caps start failing, they shed granules faster than the field shingles. If you’re seeing heavy granule grit concentrated near the roofline, the cap material is breaking down.
- A whistling or flapping sound during Santa Ana winds. A properly sealed Boral ridge vent shouldn’t move or make noise. Flapping means the fasteners have pulled loose, and whistling means air is being forced through a narrow gap that shouldn’t exist.

AfterReplacement Cost & What’s Included
For a typical single-story Ventura home with 40 to 50 linear feet of ridge, a full Boral-compatible ridge vent replacement runs about $650 to $950 including parts, labor, and disposal. Two-story homes or roofs with steep pitches push the range up to $1,100 to $1,400 because of staging, safety gear, and extra labor time. If the underlying decking is water-damaged or the existing vent was installed without proper underlayment at the ridge opening, we’ll show you photos and give you a written price for the additional repair before anything gets ordered.
Every quote you get from us is a written line-item price, delivered before work starts. The number on the quote is the number on the invoice. That’s The Relay Visibility Guarantee, and it applies to every ridge vent job we do in Ventura. You’ll also get before-and-after photos of the work, and the repair itself is covered by our 365-Day Done Right Promise: if the ridge vent fails within a year, we come back and fix it at no charge.
DIY or Call Us?
Here’s the honest split. You can safely inspect a ridge vent from a ladder at the roofline: look for cracks, lifted edges, missing end caps, and shingle cap deterioration. What you should not do is attempt the actual replacement yourself. Ridge vent work happens at the highest point of the roof, requires removing cap shingles and cutting back underlayment without nicking the decking, and any mistake at the ridge creates a direct water path into the attic. A fall from the ridge while juggling a 4-foot vent section and a nail gun is the kind of injury we don’t want anyone in Ventura taking on to save a few hundred dollars.
If you see a problem and want a straight answer about whether it needs a full replacement or just a section swap, call us at (559) 249-4917. We’ll tell you what we’d do if it were our roof, and the estimate is free.
FAQs
Boral ridge vents typically last 15 to 20 years in Ventura, though homes with full western sun exposure and no shade near the ridge often see cracking and UV breakdown on the earlier end of that range. The constant sun, salt air near the beach, and seasonal temperature swings between the coast and the East Ventura hills all accelerate plastic and sealant aging. If your vent is over 15 years old and you’re seeing any of the warning signs above, replacing it now is cheaper than the drywall repair that comes after a leak.
In some cases, yes: a single cracked section or a separated end cap can be patched or swapped without replacing the entire ridge run, and that usually costs $180 to $320. But if the vent has multiple cracked sections, lifted nails, or failed shingle caps along most of the ridge, partial repairs stop making sense, because you’ll be back on the roof in another year. We’ll tell you which situation you have and give you prices for both options before you commit to anything. Call (559) 249-4917 for an exact quote, no charge for the assessment.
Most single-story Boral ridge vent replacements in Ventura take one full day from setup to cleanup. If the job requires decking repair or underlayment replacement at the ridge opening, plan on a second day, and we’ll tell you that before we start so you’re never surprised by a crew that’s still on your roof at dinner time.
We keep Boral-compatible low-profile ridge vent sections, end caps, and connecting collars in our local inventory, so most jobs don’t require a supply house trip or a two-week wait. That’s the advantage of working with a Ventura roofing company that does ridge vent replacements regularly rather than a general handyman who has to figure out what to order. We also work with GAF, Owens Corning, and CertainTeed materials, so if your roof is a mix of brands, we can match whatever needs matching.
If your Boral ridge vent has cracked, lifted, or started leaking, don’t wait for the next storm to test it. Call Crestview Roofing Co Ventura at (559) 249-4917 and we’ll get you a written price, a crew you know by name, and before-and-after photos so you can see exactly what was done. That’s how we work, and as Dylan Pace likes to say, “If it’s not in writing, it’s not a promise.”
