CertainTeed Ridge Vent Installation: The Riverside Owner’s Guide
We stock and install CertainTeed-compatible ridge vent in Riverside, with most full ridge vent replacement jobs running between $450 and $950 installed, depending on ridge length and whether your existing vent can be reused. Most owners discover the problem the ugly way: a shingle that’s lifted near the peak, a water stain creeping across the ceiling below the roofline, or a ridge cap that’s started to curl like old wallpaper after a Riverside summer. The ridge vent is the unsung workhorse of your attic ventilation system, and when it fails, it fails quietly until the damage is already visible.
Tilehurst Roofing Riverside is an independent roofing contractor. We are not affiliated with CertainTeed, but we install their ridge vent systems regularly and keep compatible components on our trucks for Riverside jobs.
Which CertainTeed Models This Applies To
CertainTeed makes two main ridge vent lines we see on Riverside roofs: the Mountain Ridge and the Air Vent ShingleVent II, which CertainTeed acquired years ago and still supports. The ShingleVent II is the one we replace most often in Riverside, particularly on homes roofed between 2004 and 2016. It’s identifiable by its black polypropylene body and the external baffle that looks like a series of small louvers running along the peak.
Here’s the compatibility gotcha that bites homeowners: CertainTeed ridge vent is sized by ridge length, not roof square footage. A 20-foot ridge doesn’t get the same part as a 40-foot ridge, and splicing two pieces incorrectly creates a seam where wind-driven rain gets in. When we quote a Riverside ridge vent job, we measure the actual linear feet of ridge, note the existing cut width, and match the replacement to the slot already cut in your decking. An OEM CertainTeed vent runs about $3 to $6 per linear foot for the material alone. Quality aftermarket equivalents exist, but we’ve had better long-term results staying with OEM CertainTeed on existing CertainTeed systems, because the nail slots and baffle geometry actually match your existing roof cut.
Styles & brands we work with
Signs Your CertainTeed Ridge Vent Installation Is Failing
- Visibly cracked or brittle vent material. Riverside UV rays are relentless. After 12 to 15 years of direct sun, the polypropylene baffles start to chalk, then crack. Once the plastic body is cracked, water gets under it and rides the truss line into your attic.
- Shingles lifting or missing along the ridge line. The ridge cap shingles are the armor for the vent. When they start to warp or peel back, the vent loses its cover and wind-driven rain enters the gap.
- Water stains on the ceiling below the peak. This is the homeowner’s diagnosis, and it’s usually the one that gets us called. By the time water shows on the ceiling, it has been traveling through the attic for weeks.
- Attic temperature climbing noticeably in summer. Riverside regularly hits 100 degrees in July and August. If your attic feels like an oven door when you peek in, the ridge vent may not be exhausting. A failed ridge vent stops the hot air from leaving, which cook your shingles from underneath and shortens the whole roof’s life.
- Squirrel or bird activity near the peak. Rodents will chew through aged ridge vent baffles to get into a warm attic. If you’re hearing scratching at dawn in Riverside, you may have a vent breach, not an arborist’s problem.

Every Tilehurst Roofing Riverside ridge vent job includes a written price before we touch your roof, a written guarantee on the work, and our 365-Day Done Right Promise: if it’s not right, we make it right for a full year. Greg Holloway has been up and down Riverside roofs long enough to know that the price you’re quoted on the phone should be the price on the invoice.
DIY or Call Us?
You can safely check a few things from the ground or a ladder placed on level ground: look for visibly cracked vent material, lifted shingles at the peak, or granule buildup in your gutters that suggests ridge cap failure. That’s a reasonable Saturday-morning inspection. But replacing a ridge vent means working at the highest, steepest point of your roof, walking on surfaces designed to shed water, not craddle a homeowner. Falls from roof peaks are how people get hurt permanently. This is one repair where a fall costs more than the entire repair would have.
If you’ve done your inspection and the vent looks compromised, call us at (562) 315-0297. We’ll measure the ridge, confirm your CertainTeed model, and give you a written quote. No pressure, no vague numbers.
FAQs
In Riverside’s dry heat and UV exposure, a CertainTeed ridge vent typically lasts 12 to 18 years before the polypropylene body becomes brittle enough to crack or warp. Coastal-influenced areas of Southern California may see slightly longer lifespans, but Riverside’s summer sun accelerates plastic degradation. If your vent is pushing 15 years and you’re seeing ridge shingle issues, replacement is the honest answer.
Small sections of CertainTeed ridge vent can sometimes be spliced if the damage is isolated to one or two linear feet, but in practice, most Riverside failures we see are age-related, meaning the entire vent run is near end of life. Repairing one section today often means repairing another section next year. We’ll always show you the condition of the full run before recommending anything. Call (562) 315-0297 and we’ll give you the whole picture at the estimate.
A standard CertainTeed ridge vent replacement on a single-story Riverside home takes one crew day, usually 4 to 7 hours including removal, inspection of the ridge cut, resetting the vent, and replacing ridge cap shingles. Two-story homes or multiple ridge lines add time. We’ll tell you the schedule when we quote it.
We keep common CertainTeed ShingleVent II and Mountain Ridge vent sections on our trucks, along with compatible ridge cap shingles in several standard colors. If your home needs a specific color match or a less common vent profile, we can source it through our supplier network that includes GAF, Owens Corning, and the other manufacturers we work with. We’ll tell you upfront if a special order adds lead time to your job.
If your CertainTeed ridge vent is failing, don’t wait for the next Riverside rain. Call (562) 315-0297 and we’ll schedule your free estimate. We tell you the price before we touch your roof. That’s just how it should work.
