Boral Ridge Vent Installation Nationwide

Boral Ridge Vent Installation: The San Antonio Owner’s Guide

Boral ridge vent installation in San Antonio typically runs between $22 and $38 per linear foot installed, and most single-family homes fall between $700 and $1,400 total depending on roof length and access. We stock Boral-compatible ridge vent material on our trucks, so most installations are completed the same day we arrive. Most homeowners discover a failed ridge vent the hard way: a musty smell in the attic, a spike in the July electric bill, or water stains on the ceiling after a hard Hill Country downpour.

Ridge vent is the exhaust half of your roof’s ventilation system. It runs along the peak and lets hot, humid air escape so your attic doesn’t bake. When it cracks, lifts, or clogs, the whole system stops breathing. In San Antonio’s heat, that means attic temperatures climb past 140°F and your AC works harder than it should.

Which Boral Models This Applies To

Boral manufactures ridge vent under their roof ventilation line, and the two configurations we see most often in San Antonio are the 4-foot rigid plastic sections and the 20-foot rolls. The rigid sections interlock with end caps and baffles, while the rolled version sits lower-profile and works with Boral’s concrete and clay tile profiles more cleanly.

Here’s the compatibility gotcha most people don’t know: Boral ridge vent is engineered to match Boral’s specific tile and slate profiles. The vent’s external baffle and weather filter are sized for the air gap Boral tile creates at the ridge. Swapping in a generic big-box vent often leaves gaps that invite wind-driven rain or lets embers from a neighbor’s grill find their way in. That’s why we recommend OEM Boral ridge vent or a quality aftermarket equivalent verified against Boral’s spec sheet, not whatever is cheapest on the shelf.

To identify your current vent, check the underside of a section for a Boral stamp or molded part number. If the stamp is faded, measure the width. Boral ridge vent sections are typically 11 to 12 inches wide with a 4-foot length for rigid sections. We’ll confirm the exact match during the estimate.

Signs Your Boral Ridge Vent Installation Is Failing

• Attic feels like a sauna in the afternoon. Ridge vent that’s cracked or clogged can’t exhaust hot air, so it collects at the peak where the vent sits. You’ll notice the upstairs bedrooms run 5 to 8 degrees warmer than the rest of the house.
• Water stains on the ceiling near exterior walls. Wind-driven rain slips through gaps where vent sections have separated or lifted. In San Antonio, our spring storms push rain sideways hard enough to find every weak seam.
• Granules or debris piled inside the vent opening. Over time, hail and wind drive roofing granules, dust, and even cottonwood seeds into the vent. A clogged ridge vent is functionally the same as no ridge vent.
• Visible cracking or sun damage on the vent plastic. San Antonio UV exposure is brutal. Boral’s plastic ridge vent can become brittle after 10 to 15 years, and once it cracks, water gets underneath.
• Higher summer electric bills with no other explanation. Poor attic ventilation forces your AC to run longer. If your bill jumped and the attic is hot, the ridge vent is a prime suspect.

Replacement Cost & What’s Included

For most San Antonio homes, Boral ridge vent replacement runs $22 to $38 per linear foot installed. A 40-foot ridge, which is common for a single-story ranch in neighborhoods like Alamo Heights or Castle Hills, typically lands between $880 and $1,520. Two-story homes with longer ridges or complex tile transitions run higher.

What drives the range: roof pitch and access (steeper or tile roofs take more time and safety setup), whether we’re replacing just the vent or also the underlayment at the ridge, and whether the existing vent was OEM Boral or a generic we need to retrofit. The price we write covers the material, labor, disposal of the old vent, and the workmanship warranty. You’ll see the exact number in writing before any work starts, and that number doesn’t change unless we find something structural once the old vent is off, in which case we stop and talk to you first.

DIY or Call Us?

Replacing ridge vent means working at the highest point of your roof, often on a tile or steep-pitch surface. That’s a fall-risk height and a place where one wrong step damages tiles you’ll pay more to replace than the vent job itself. We don’t recommend homeowners tackle this one, and we say that even though it costs us a sale when someone tries.

What you can safely do is check from the ground or a ladder without climbing onto the roof: look for sections that have separated, cracked, or lifted, and peek into the attic on a bright day to see if daylight comes through the ridge. If you spot damage, call us at (903) 354-7802. We’ll come out, measure, write you a price, and get it handled without you ever needing to leave the ground.
