Boral Ridge Vent Installation: The San Antonio Owner’s Guide
We stock and install Boral-compatible ridge vent systems for San Antonio homes, with most jobs running $380-$720 installed depending on ridge length and whether the existing decking needs repair. Same-day service is available when you call before noon, and our trucks carry the common Boral profiles used across Alamo Heights, Stone Oak, and the older ranch-style roofs out near Lackland. Most homeowners realize something’s wrong when they spot water stains on the ceiling after a hard rain, or when their attic starts feeling like a kiln even with the AC running flat out.
Which Boral Models This Applies To
Boral’s ridge vent lineup breaks into a few distinct families, and matching the right profile matters more than most people realize. The Boral Stone-Coated Steel systems, common on the tile-look metal roofs you see throughout Terrell Hills and Monte Vista, use a vented closure strip that sits under the ridge cap itself, not a traditional shingle-over vent. Boral’s concrete and clay tile lines, meanwhile, pair with either high-profile or low-profile vented ridge pieces depending on the tile lift height. The label you want is usually stamped on the underside of an existing ridge cap piece, or molded into the plastic vent body if you’re looking at a prior repair. We carry both OEM Boral components and the Carlisle-certified aftermarket equivalents that meet the same NFA ratings, because sometimes the original part has been discontinued and the homeowner still needs a roof that breathes right. Cecil Hargrove learned early in his Bexar County days that mixing a high-profile vent with low-profile tile is a recipe for wind-driven rain getting a running start straight into your attic. We check the tile gauge and ridge pitch before we quote, not after we show up.
Signs Your Boral Ridge Vent Installation Is Failing
- Water stains on the ceiling after storms. The vent’s end dams or internal baffles have cracked or pulled loose, letting wind push rain straight through what should be a one-way air path. On Boral metal systems, we often find the foam closure strips have hardened and shrunk from San Antonio’s UV exposure.
- Attic temperature spikes even with good insulation. The vent’s intake NFA (net free area) has dropped because debris, wasp nests, or collapsed internal filter mesh are choking airflow. Your ridge vent becomes a decorative cap instead of an exhaust path.
- Visible gaps or lifted ridge cap along the peak. Fasteners have backed out or the vent’s nail flange has fatigued, breaking the seal that keeps wind from peeling the ridge cap back. This is common after hail events in the Hill Country corridor.
- Musty smell or mold spotting in the attic. Moisture is getting trapped because the vent can’t exhale humid air fast enough, usually from a combination of blocked exhaust and poor soffit intake that overloads the system.
- Shingle granules or tile debris collecting at the gutter ends. The ridge vent’s internal baffles have deteriorated, allowing the vent to act as a vacuum during wind events and pull material off the roof surface.
Replacement Cost & What’s Included
In the San Antonio market, a straightforward Boral ridge vent replacement on a typical 40-foot ridge runs $380-$520. If we’re dealing with longer runs, multiple ridge sections, or decking that has softened from prior leaks, the job can reach $620-$720. That price includes removal of the failed vent and ridge cap, inspection of the underlying decking, installation of the new Boral-compatible vent with proper end dams and weather seals, and reinstallation or replacement of the ridge cap material. We don’t quote one number and invoice another. The 90-Day Done Right Promise covers the workmanship, and we document the before condition with photos so you see exactly what we found. Most single-ridge jobs finish in four to six hours, and we haul away the old material.
DIY or Call Us?
There’s a safe middle ground here. A homeowner can walk the attic and look for daylight showing through the ridge line, or check the vent exterior for obvious cracks and gaps from the ground with binoculars. What you should not do is climb the peak yourself. Ridge work means working at the highest, most exposed point of the roof, and Boral’s stone-coated steel and tile systems require specific fastening patterns that vary by profile. Get the pattern wrong and you’ve created a leak path that won’t show itself until the next big storm. We’ve also seen homeowners install a standard shingle vent on a Boral tile system and wonder why the ridge cap won’t seat properly. If you’re unsure about the profile match, call us. A live person answers at (833) 756-5022, and we’ll send a technician to identify the part and give you an upfront price before any work starts.
FAQs
How long does a Boral ridge vent last in San Antonio?
A properly installed Boral ridge vent should give you 15-20 years, but the foam closure strips on metal systems often harden and fail in 8-12 years from our intense UV and heat cycling. Call (833) 756-5022 for a free inspection if you’re past the decade mark.
Can a failing ridge vent be repaired instead of replaced?
Patching usually costs more than it saves. Once the internal baffles or end dams are compromised, spot fixes leak eventually. We replace the full vent section so the warranty and the 90-Day Done Right Promise both stay intact. Call (833) 756-5022 and we’ll show you exactly what we found.
How long does the replacement take?
Most single-ridge Boral vent replacements take four to six hours from setup to cleanup. Larger homes in the Hill Country with multiple ridge lines may need a full day. We complete most jobs in one visit. Call (833) 756-5022 to schedule.
Do you stock Boral ridge vents on your trucks?
We carry the common Boral profiles and the Carlisle-certified equivalents that match the NFA specs. For discontinued or specialty sizes, we source overnight from our San Antonio supplier. Either way, we don’t leave you waiting. Call (833) 756-5022 to confirm availability for your model.
A roof either holds or it doesn’t. We build ones that hold.
