CertainTeed Ridge Vent Installation Nationwide

CertainTeed Ridge Vent Installation: The Woodland Hills Owner’s Guide

CertainTeed ridge vent installation in Woodland Hills typically runs $850 – $1,400 installed, including the vent material, underlayment work at the ridge, and new shingle caps over the vent. Most failed CertainTeed ridge vents we replace are discovered two ways: the homeowner sees shingles lifting or missing at the peak after a Santa Ana wind event, or they notice attic temperatures climbing in July and August when the vent has clogged or separated. We stock CertainTeed-compatible ridge vent rolls on our trucks, so most replacements are done in a single visit without a second trip to a supply yard.

If you’re reading this, you probably already know the part. What you need now is a straight answer on compatibility, cost, and whether the old vent can be salvaged or needs to come out. That’s what this page covers.

Key Takeaways

• Typical installed cost in Woodland Hills: $850 – $1,400, depending on ridge length and existing shingle condition.
• CertainTeed ridge vents use a specific profile; generic box-store vents often don’t match the original shingle line cleanly.
• UV degradation in the San Fernando Valley sun is the #1 killer of ridge vent material, not wind.
• We carry CertainTeed-compatible vent on the truck and can usually replace a failed section same-day.
• Every job includes a written price before work starts and a 365-day repair warranty in writing.

Which CertainTeed Models This Applies To

The most common CertainTeed ridge vents we replace in Woodland Hills are the CertainTeed Ridge Vent (rigid PVC) and the CertainTeed EZ Vent, a flexible rolled vent that follows uneven ridge lines. If your home has architectural shingles from the CertainTeed Landmark, Presidential Shake, or Highland Slate lines, the ridge vent was likely paired with those shingles at installation and sits under a matching cap shingle.

Here’s the compatibility gotcha most homeowners don’t know: the vent’s width and nail flange must match the original cut at the ridge opening. A typical ridge vent runs 9 to 12 inches wide, and the slot cut into the roof deck is usually 2 to 3 inches across at the peak. If a previous roofer installed a narrower vent than the deck opening, you get blowback that pushes hot air back into the attic instead of venting it. We measure the slot, the vent width, and the cap shingle overhang before recommending anything.

On the OEM versus aftermarket question: CertainTeed’s own vent material is a rigid PVC with a baffled design that deflects wind-driven rain. Some aftermarket equivalents use a thinner plastic that gets brittle faster in Woodland Hills heat. We install both, but if you have CertainTeed shingles with an active warranty, using a vent of similar profile keeps things cleaner if you ever file a claim. Crestview Roofing Co Woodland Hills is an independent contractor and not affiliated with CertainTeed, but we install CertainTeed-compatible vent and matching cap shingles from their product lines alongside GAF and Owens Corning components.

Signs Your CertainTeed Ridge Vent Installation Is Failing

• Missing or cracked cap shingles at the peak. The cap shingles over the vent take direct sun all day. After 12 to 15 years in Woodland Hills, the asphalt in those caps breaks down faster than the field shingles, exposing the vent underneath.
• Attic feels hotter than it should in summer. If the vent’s baffles have warped or collapsed from UV exposure, air stops moving through the ridge. Your attic fan or gable vents end up doing all the work, and your cooling bill climbs.
• Visible daylight through the attic at the ridge line. Cracked vent material or separated sections let light in, which also means rain gets in during winter storms.
• Water stains on ceiling drywall near exterior walls or along the peak. This usually means the vent’s end caps or nail flanges have pulled loose, letting water run along the underside of the decking.
• Granules from cap shingles collecting in gutters. The cap shingles over the vent shed granules first. If you see heavy granule loss in your gutters and the roof is over 10 years old, the ridge is often the first failure point.

Replacement Cost & What’s Included

In Woodland Hills, a full CertainTeed ridge vent replacement with new cap shingles runs $850 – $1,400 installed for a typical single-story home with 30 to 50 linear feet of ridge. The range comes down to three things: total ridge length, whether the existing deck opening needs to be recut, and whether we’re pulling old cap shingles that have fused to the vent beneath.

• Vent material (CertainTeed-compatible, 20 ft sections): $180 – $320
• Labor for removal and installation: $400 – $700
• New cap shingles and fasteners: $150 – $280
• Deck repair or slot widening, if needed: $120 – $250

The number we write on your estimate is the number on the invoice. No line items appear after the fact, no “supplemental” charges when we find deck damage. If we open the ridge and find additional rot, we stop, send you photos, and give you a written change order before any added work. Every ridge vent replacement is covered by our 365-Day Done Right Promise: if the vent or cap fails within a year, we come back and fix it at no charge. That’s in writing, included with the job.
