Boral Ridge Vent Installation: The Los Angeles Owner’s Guide
Boral ridge vent installation in Los Angeles typically runs $14 to $22 per linear foot installed, with most single-family homes landing between $550 and $1,300 for the full job. We stock Boral-compatible ridge vent materials on our trucks for same-week installation across LA County, from the Valley to the Westside. Most homeowners discover their ridge vent has failed the same way: a spike in upstairs heat, an attic that smells like hot dust, or shingles lifting along the peak after a Santa Ana wind event. If that sounds familiar, this page covers exactly what happens next and what it costs.
We should say this up front: Tilehurst Roofing Los Angeles is an independent roofing contractor, not a Boral distributor or affiliate. We’re one of the few LA roofing crews that keeps Boral-compatible ridge vent parts in regular stock, because we’ve seen too many homeowners wait two weeks for a special order while their attic bakes or their roof edge stays open to rain. Greg Holloway, our owner, grew up in Reseda and has spent over a decade on LA roofs. He’ll tell you a Boral ridge vent rarely fails because the product was bad. It fails because someone installed it wrong, or because a roof cleaner walked on it, or because years of San Fernando Valley heat turned brittle plastic into something that cracked along the nail line. Knowing which one happened tells us how to fix it right.
Which Boral Models This Applies To
Boral’s roofing division produces ridge vent products under several lines, and compatibility matters more than most LA homeowners realize. The Boral EasyVent and Boral Rapid Ridge lines are the two you’ll most commonly find on Southern California homes. EasyVent is a lower-profile vent, roughly 11.5 inches wide, designed to sit almost flush under the ridge cap shingles. Rapid Ridge uses a baffled core that’s taller and stiffer, and it handles slightly higher airflow per linear foot. The two are not interchangeable on every roof, and mixing them on the same ridge line creates an uneven vent line that’s both ugly and less effective.
If you’re not sure which vent you have, look for the model stamp on the end of the vent material at the gable edge or near the ridge end. It’s usually printed in raised lettering. If the vent is only partially failed, we can match the remaining sections. If it’s been painted over or the stamp is gone, we measure the vent opening width and the height of the baffle. That gives us a reliable match without guesswork. One LA-specific gotcha: homes built during the 2012-to-2015 building boom in neighborhoods like Porter Ranch and Playa Vista sometimes got a Boral vent that was later discontinued. We keep a few of those older-profile vents in stock for exactly that reason, because the answer should not be “replace the whole ridge vent system” just because one 8-foot section failed.
When it comes to OEM versus aftermarket, Boral-branded vent material is still manufactured, but lead times can stretch to a week or two depending on the warehouse. Quality aftermarket equivalents from O’Hagin and Lomanco match the profile and airflow specs of most Boral models, and we stock those as well. We’ll quote you both options plainly and let you decide. Either way, the vent is manufactured to the same performance range. The installation is what determines whether it works.
Styles & brands we work with






Signs Your Boral Ridge Vent Installation Is Failing
- Upstairs rooms are suddenly 10 to 15 degrees hotter. A working ridge vent moves hot air out of the attic continuously. When the vent collapses or the baffle gets clogged with dust, the attic heat has nowhere to go, and it pushes down into the living space through the ceiling. This is the symptom owners notice first, especially during LA’s September and October heat waves.
- You can see daylight through the ridge from inside the attic. If the vent mesh has torn or a section has lifted, you’ll see thin slivers of light along the peak. That same gap lets wind-driven rain in during winter storms, and it lets embers in during fire season. This is the one to check after any big Santa Ana event.
- Ridge cap shingles are lifting, curling, or separating at the peak. The ridge vent sits under those cap shingles. When the vent warps or the nails back out, the shingles above lose their anchor and start to lift. On a breezy day, you may hear a faint flapping sound from the roof peak.
- Attic smells like hot asphalt or burnt dust. A blocked or failed vent lets attic temperatures climb past 140 degrees in summer. That heat bakes the underside of the roof deck and the shingles from below. The smell is distinctive, and it means the vent stopped doing its job months ago.
- Visible cracking along the vent’s nail line. Plastic ridge vent material expands and contracts with temperature swings. After 8 to 10 years of LA sun, older Boral vent sections can become brittle and crack where the roofing nails hold them down. Once the nail line cracks, the vent section loosens and starts to slide or lift.

AfterReplacement Cost & What’s Included
Here’s the pricing picture in real dollars, because you should know this before you pick up the phone. Boral-compatible ridge vent replacement in Los Angeles runs $14 to $22 per linear foot installed. A typical 40-foot ridge line lands between $560 and $880. If the ridge needs new cap shingles as part of the job, which is common when the old caps are cracked from heat, add $180 to $420 depending on the shingle match. Most full replacements in LA finish between $550 and $1,300.
What drives the range? Roof pitch matters: a steep roof takes longer and costs more. Single-story versus two-story affects access and hauling. And if the original vent was installed without enough nails, or with the wrong nails entirely, we may need to redo the whole ridge line rather than swap one section. Every one of our quotes includes the vent material, the labor, removal and disposal of the old vent, new cap shingles if needed, and a written guarantee on the work before the crew leaves. No change orders at the door. No “we found something else while we were up there” surprises. We price it first, in writing, and that’s the price.
DIY or Call Us?
You can safely check a few things yourself from inside the attic: look for daylight at the ridge, feel for excessive heat, check for water staining along the peak. That’s all useful information for us. What you shouldn’t do is get on the roof and start pulling vent sections. Ridge vent replacement means working at the highest point of the roof, where the slope is steepest on both sides. A fall from the ridge is a hospital trip at best. The work also involves removing cap shingles, cutting vent sections to match the ridge length, and re-nailing everything so the vent stays sealed against wind and embers. If a nail placement is wrong, the vent leaks within a season. At that point, you’ve spent a weekend on your roof and you still need to call us.
Most Boral ridge vent replacements take one to four hours for a trained crew. We’ve got the parts on the truck, we know what the Boral profile looks like from every angle, and we’ll tell you the price before we touch the roof. Tell you the price before we touch the roof. That’s the only way we know how to start.
FAQs
A properly installed Boral ridge vent lasts 15 to 25 years in the LA climate, though the UV exposure on roofs in valley areas like Encino and Woodland Hills can push the lower end of that range faster than coastal roofs in Torrance or Redondo Beach. Most fail before 15 only if they were under-nailed during installation, walked on by a tradesperson, or damaged by a roof cleaning wand. If you’re at 10 years and starting to see attic heat spikes, it’s worth having a look before the ridge caps start lifting. Call us at (213) 674-2890 for an exact assessment and quote.
Sometimes a single section can be swapped out if the remaining sections are intact and the failure is isolated to a cracked or dented vent segment. But when the nail line has failed, the plastic is brittle in multiple places, or water has been getting in along the ridge, a full ridge vent replacement is the honest fix. We’ll inspect first and tell you what’s actually needed, not what’s convenient to sell. Estimates are free.
A standard ridge vent replacement on a single-family LA home takes one to four hours on site. Steep roofs or two-story homes add time. You don’t need to be home for the work, though we’ll walk you through what was found and what was done before we leave. Call (213) 674-2890 to schedule your free estimate.
Yes. We keep Boral-compatible ridge vent sections, including some discontinued profiles, on our trucks and in our local LA inventory.

Call (213) 674-2890 and we’ll confirm the part while you’re on the phone.
