Boral Ridge Vent Installation: The Long Beach Owner’s Guide
We stock Boral-compatible ridge vent material on our trucks and install it throughout Long Beach, with most complete ridge vent replacements running between $850 and $1,900 depending on roofline length and the condition of the existing vent channel. Most homeowners discover their ridge vent has failed when attic temperatures climb in August or they find fine grit and moisture staining near the peak. Here’s what you need to know before you spend a dollar.
Key Takeaways:
- Boral ridge vents rely on an external baffle design that fails differently than GAF or Owens Corning equivalents, and we’ll explain why below.
- You don’t need to replace the whole roof for a failed ridge vent. The vent is swappable as a standalone component.
- We provide a written price before anyone climbs a ladder, so you’ll know the full number before work starts.
Which Boral Models This Applies To
Boral ridge vent systems fall into a few distinct lines: the Boral Cedar Ridge Vent, the Boral Tile Ridge Vent (sometimes specified for concrete and clay tile profiles), and the Boral Profile Vent, which works with specific Boral metal and stone-coated steel systems. The compatibility gotcha we run into in Long Beach is this: Boral’s tile-profile ridge vents are matched to specific tile profiles, and what fits a Flat Shake will not sit correctly on a Barcelona or Villa profile, even though they look close from the ground. If the vent base doesn’t match the tile contour, you’ll get wind-driven rain intrusion at the seam within the first winter.
On the identification side, there’s almost always a stamp or embossed code on the underside of the vent section. Those codes are small, and they’re often hidden under accumulated dust. If you can’t find one, measuring the vent base width and the profile rise is the next best step; we do this from the roof, not from a ladder leaned against the gutter. For the record, Birchbark Roofing Long Beach is an independent roofing contractor, not a Boral dealer or affiliate. That matters because we’re not trying to upsell you into a Boral-branded part when a quality compatible equivalent does the job for less. When an OEM Boral vent makes sense for a warranty-sensitive tile roof, we say so. When a properly speced aftermarket baffle vent performs identically for a better price, we say that too and put both numbers in writing.
Styles & brands we work with






Signs Your Boral Ridge Vent Installation Is Failing
- Attic heat that won’t drop at night. A working ridge vent lets hot air exit along the peak. When the baffle collapses or the vent material deforms under Long Beach sun, that heat stays put, and your air conditioner works harder.
- Visible sagging along the ridge line. Boral’s external baffle vents are rigid but not indestructible. Years of UV exposure can cause the polymer to soften and deform, especially on south-facing roofs in the Los Angeles basin.
- Dry rot or moisture staining near the ridge inside the attic. A cracked vent base or failed end cap lets water in during winter rains. By the time you see the stain on the ceiling, the decking under the vent has been damp for a while.
- Bird or rodent activity in the attic near the peak. When the vent’s exterior baffle cracks, it leaves an opening big enough for small animals. We have pulled nests out of failed ridge vents more times than I can count, and it’s usually a sign the plastic has degraded enough to break under hand pressure.
- Granules collecting in the gutter below the peak. If a ridge vent is not seated flush against the shingles or tiles, wind gets under it and works the roofing material loose. The grit in your gutter, especially on the prevailing wind side, is the early warning.
Replacement Cost & What’s Included
In Long Beach, a full Boral-compatible ridge vent replacement runs between $850 and $1,900 installed for a typical single-family roofline. The spread depends on three things: linear footage of ridge, whether the existing vent channel was cut correctly in the first place (a surprising number were not), and whether we need to replace damaged end caps or trim flashing. Parts alone typically run $6 to $12 per linear foot. Labor and set-up make up the remainder.
Every quote includes the vent material, any fasteners or sealant, end caps, roof protection during the work, and the full clean-up afterward. We write the complete number down before any work starts, and that number doesn’t move unless we find something structural under the vent that changes the scope, which we’d show you and price before touching it. The whole replacement is covered by our 365-Day Done Right Promise: if the vent install isn’t right, we make it right. No charge, no back-and-forth.
Call (562) 512-7366 and we’ll set a time to walk the roof and get you a written estimate. If the vent has already cracked and you’re seeing moisture, earlier is better than later, but we’re not going to pressure you into a decision on the spot. Look at the number, see the scope, and decide on your own timeline.

Here’s the honest split. There are a few things you can do from a safe ladder or from inside the attic: check for visible cracks, look for displaced end caps, and confirm whether the vent is sagging. That’s information gathering, and it’s useful. What you should not do is walk a ridge line to swap out vent sections. Ridge work puts you on the steepest part of the roof, and a fall from that height is a life-changing event, not a sprained ankle.
Beyond the safety piece, the reason DIY ridge vent swaps often go wrong is that the vent’s performance depends on how it’s seated. If the baffle isn’t secured evenly along the ridge, wind lifts it. If the end caps aren’t set flush, water gets in. A functional ridge vent is a system, not a part stuck on the peak, and it works only when the vent channel underneath is sized right against the vent’s net free area. We measure, we match, we install, and we photograph the completed work from the ridge before we climb down. If you’d rather stay on the ground, call (562) 512-7366.
FAQs
A properly installed Boral-compatible ridge vent in this climate typically lasts 12 to 18 years before UV degradation starts causing visible cracking or sagging. Coastal exposure near the shore takes more of a toll on the plastic than inland heat alone. If your vent is over 15 years old and you’re seeing signs of failure, replacement is the better spend than trying to patch it. Call (562) 512-7366 and we’ll check its condition as part of the estimate.
Small cracks near the cap can sometimes be sealed, but that’s a temporary stop, not a fix. The polymer degrades across the whole section, not just at the visible crack, and the next failure is usually weeks or months away. We’ll tell you honestly whether repair buys you time or is money wasted, and for most Long Beach roofs we see, full replacement of the failed vent sections is the right call. Estimates are free, so call us for the real picture.
A typical single-family ridge vent replacement in Long Beach takes four to six hours from set-up to final clean-up. That includes removing the old vent, inspecting and possibly trimming the vent channel, installing the new vent sections, and sealing the end caps. You’ll get a photo of the completed clean-up before our crew leaves. Schedule your estimate at (562) 512-7366.
We carry Boral-compatible vent sections, end caps, and sealant on our installation vehicles, along with compatible vent material for GAF, Owens Corning, and CertainTeed systems. That means most Long Beach ridge vent replacements can happen in a single visit without waiting on a parts order. If you have a Boral tile-profile vent that requires a specific OEM part, we’ll know that after we see the roof and we’ll give you a straight timeline.
Get Your Boral Ridge Vent Priced in Writing
A written price before anyone climbs a ladder, that’s where we start. If your ridge vent is failing, we’ll walk the roof, assess what’s compatible with your Boral system, and give you a fixed number for the work. Shoe covers at the door, drop cloths through the hallway, all debris cleared and photographed before we leave. It’s a simple job when it’s done carefully, and that’s how we do it.
Call (562) 512-7366. A live person answers, day or night. Ask for a ridge vent estimate and we’ll get you on the schedule. You’ll know the price before anyone starts work, and you won’t be wondering whether the clean-up happened after we’re gone. It happens, and we have the photo to prove it.
