Boral Ridge Vent Installation: The Dallas Owner’s Guide
Boral ridge vent installation in Dallas typically runs $14 to $22 per linear foot installed, with most homes landing between $650 and $1,400 total depending on ridge length and the condition of the existing roof deck. We stock Boral-compatible ridge vent material on our trucks, so most replacements are one trip and a few hours. The way most Dallas homeowners find out their ridge vent has failed is subtle: they notice the upstairs feels hotter in July than it did last year, or they spot granules building up in the gutters near the peak.
Ridge vents do not make noise when they fail. They do not leak dramatically. They degrade slowly, and in North Texas, that degradation happens faster than most homeowners expect. Travis Oakley has pulled enough Boral ridge vents off Dallas roofs to know the failure pattern: cracked plastic end caps, brittle shingle-over sections, and sun-damaged vent channels that let rain blow in sideways during spring storms.
Key takeaways:
- We install Boral-compatible ridge vent on Dallas homes for $14 to $22 per linear foot installed
- Most jobs are done in a single visit: existing vent removed, new vent installed, shingles sealed
- The written price comes before any work starts, and it does not change at the door
- Every install is covered by our 365-Day Done Right Promise in writing
Which Boral Models This Applies To
Boral has produced a few distinct ridge vent lines over the years, and the most common one we replace in Dallas is the Boral ProfileVent and its shingle-over cousin, the Boral MultiVent. Both are low-profile plastic designs intended to sit under cap shingles and blend with the roofline. The profile is shallower than standard rolled vents, which means the nail placement has to be precise or the vent collapses under the cap shingles in Dallas summer heat.
Identifying what you have matters, because the replacement has to match the existing cut slot in your roof deck. Measure the vent width. Boral ProfileVent is roughly 10.5 inches wide and needs a 3.5-inch deck opening. Some aftermarket universal vents need a different slot width, and if the slot does not match, you are cutting your deck or leaving a gap. Neither is acceptable on a Dallas house where wind-driven rain is a spring routine.
One compatibility gotcha worth knowing: Boral’s older ProfileVent uses a thinner plastic than current production, and the original vent often has the model name molded into the underside of each section. If you can see a partial label or measure the exposed vent width, we can match it before we ever set foot on the roof. We carry Boral-compatible vent sections and also stock GAF, Owens Corning, and CertainTeed alternatives for cases where an exact Boral match no longer exists.
Brennan Roofing Co Dallas is an independent roofing contractor. We are not affiliated with Boral, but we have worked with their ridge vent products on Dallas homes for years, and we know the sizing and failure points better than most.

Signs Your Boral Ridge Vent Installation Is Failing
- Granule buildup at the gutter line near the roof peak. Ridge vents sit under cap shingles, and as those cap shingles age in Dallas UV exposure, they shed granules faster than the rest of the roof. If you are seeing heavy granule accumulation in gutters near the ridge, the vent and its surrounding shingles are likely in their final years.
- Displaced or cracked cap shingles at the ridge. Boral’s low-profile vents rely on the cap shingles for their finished look and a layer of weather protection. When those cap shingles curl or crack, the vent underneath is exposed to direct sun and starts degrading faster than intended.
- Upstairs rooms run 5 to 10 degrees hotter than the rest of the house. Ridge vent failure throttles attic airflow first. The upstairs is where homeowners feel it before they see anything. If the attic is not moving air, the HVAC system compensates, and your July electric bill tells the story.
- Wind-blown water marks in the attic near the peak. This one is serious. A cracked Boral vent channel or missing end cap lets horizontal rain enter the attic. The water marks are usually faint, often mistaken for old staining. We find them with a flashlight and an honest look during a ridge vent inspection.
- Visible plastic degradation at the ridge ends. Walk the lawn and look at the peaks from the ground. If the exposed vent ends at the gable appear chalky, cracked, or warped, the plastic is heat-fatigued. Dallas summers will do this to any polymer left in direct sun for a decade or more.
Replacement Cost & What’s Included
Boral ridge vent replacement in Dallas runs $14 to $22 per linear foot installed. A typical single-story Dallas ranch with 40 to 60 feet of ridge is a $650 to $1,300 job. A two-story home with complex ridges can push toward $1,400 to $1,600 all in. The price includes removing the old vent and any failed cap shingles, inspecting the exposed deck slot for rot or damage, installing the new Boral-compatible vent, and sealing the cap shingles back down.
What drives the range? Ridge length is the obvious one, but so is the condition of the surrounding shingles. If the cap shingles near the failing vent are shot, those get replaced as part of the job and the cost moves to the high end of the range. We write every one of these line items on paper before any work begins. You will know the exact number, and it will not move at the door.
Every Boral ridge vent install carries our 365-Day Done Right Promise. That is a written guarantee for one full year, and if anything fails in that window, we come back at no charge. No fine print, no call-back fee.

There are two things a Dallas homeowner can safely check, and we encourage both. First, look at the ridge from the ground with a pair of binoculars. Cracked cap shingles and chalky plastic tell you enough. Second, check the attic on a bright day. Light bleeding through the ridge vent is normal. Light through holes or tears in the plastic is not.
Here is where DIY goes wrong: ridge vent replacement means standing at the apex of a sloped roof, removing cap shingles and old vent sections, and re-nailing everything in a straight line while keeping the vent channel aligned. That is a fall-risk job even for a careful homeowner. And the Boral low-profile design does not forgive misaligned nails. Too low, and the vent collapses. Too high, and the cap shingles do not seal. We have rebuilt more than a few homeowner attempts in Oak Cliff and Lake Highlands where the ridge looked fine from the street and leaked from the attic. A roof either keeps water out or it doesn’t, as Travis says, and everything else is just conversation. If you would rather not test that from a ladder on a 12/12 pitch, call (903) 499-4441 and get a written price from a crew that does this every week.
FAQs
A Boral ridge vent in Dallas weather typically lasts 12 to 18 years, which is shorter than the manufacturer’s projected lifespan because of our UV intensity and spring hail. The plastic degrades faster than most other roofing components, and it is often replaced at the mid-point of the roof’s life rather than at the end. Call (903) 499-4441 and we can inspect yours and tell you exactly where it sits in that range.
Partial repair works only when the damage is isolated to a single section or end cap, and even then it is a short-term fix. We do not recommend it for Dallas homes because the rest of the vent is usually in the same condition. Replacing the full run gives you a matched, continuous vent that handles our spring wind-driven rain properly. We will quote both options on paper so you can decide with real numbers in front of you.
Most Boral ridge vent replacements in Dallas are completed in three to five hours. The job is contained to the ridge line, so we are not tearing off large sections of the roof. A two-story or complex ridge may stretch into a second morning, and we will tell you that on the written estimate before any work starts.
We stock Boral-compatible ridge vent sections and common end caps on our trucks, along with GAF, Owens Corning, and CertainTeed options. If your home has a less common Boral profile that requires a special order, we can have it within a week. Either way, the estimate covers the material cost, and you approve it before the order is placed.

If your ridge vent is showing its age or already letting water into the attic, do not wait for the next North Texas spring storm to make it worse. Call (903) 499-4441 and talk to a live person, not a voicemail.
