CertainTeed Shingle Repair: The Woodland Hills Owner’s Guide
CertainTeed shingle repair in Woodland Hills typically runs $450 – $1,200 installed, depending on how many shingles failed and whether the underlayment or flashing needs work too. We stock CertainTeed-compatible replacement shingles on our trucks and can usually complete a standard repair the same day. You’ll most likely notice the problem after a Santa Ana wind event or the first heavy rain of the season: a shingle in the yard, granules washing into your gutters, or a dark water stain creeping across a ceiling.
Which CertainTeed Models This Applies To
The repair process is essentially the same across CertainTeed’s residential shingle lines: XT 25, Landmark, Landmark Pro, Presidential Shake, and Highland Slate. The part you need is the replacement shingle, but matching it correctly matters more than most homeowners realize. CertainTeed runs its color blends in production lots, and a shingle from a different lot can look visibly off even when the color name is identical. Before we write a price, we pull a full shingle from an inconspicuous spot, check the manufacturer date code on the wrapper or the bundle label, and match both the color code and the blend. Woodland Hills homes are sun-exposed nearly year-round, so even a three-year-old roof has faded enough that we order from the current lot rather than pulling from old inventory. If your original shingles are discontinued, we source the closest current CertainTeed equivalent and confirm the match with you before installing anything.
Styles & brands we work with






Signs Your CertainTeed Shingle Repair Is Failing
- Bare patches where granules should be. UV exposure in Woodland Hills accelerates granule loss on CertainTeed shingles, especially on south-facing roof planes. Once the asphalt layer is exposed, the shingle degrades fast.
- Curling or cupping at the shingle corners. This usually means trapped moisture in the attic is cooking the shingles from below. It rarely improves on its own, and the affected shingles typically crack within a season or two.
- Cracked shingles running parallel to the roof slope. Thermal expansion and contraction over decades causes hairline cracks that eventually split through the mat. This is more common on older XT 25 installs than on Landmark Pro, which uses a heavier mat.
- Shingles sliding out of place or missing entirely. If you find shingles in your yard after a wind event, the sealant strips have failed. Once the wind gets under one shingle, the neighboring shingles get loosened quickly.
- Water stains on ceilings or walls that appear only during rain. A single failed shingle can channel water along the underlayment for several feet before it finds a seam. The leak rarely lines up directly under the damaged shingle.

AfterReplacement Cost & What’s Included
In Woodland Hills, most CertainTeed shingle repairs run between $450 and $1,200, installed. A small repair of 3 to 6 shingles with sound underlayment sits at the low end. If the paper underneath is torn or the decking is soft, or if we’re replacing shingles around flashing, the job climbs. The written price includes the CertainTeed shingles or a quality aftermarket match of equal spec, new sealant, replacement nails, and cleanup. You get a written price before any work starts, and the number on the page is the number on the invoice. The repair is covered by our 365-Day Done Right Promise: if a covered repair fails within a year, we correct it at no charge, and a second visit is free. No negotiation, no runaround.
DIY or Call Us?
You can absolutely take a set of binoculars and inspect your roof from the ground. Look for missing shingles, raised edges, and visible cracks. What you cannot safely do is climb a ladder onto a Woodland Hills roof in July, when surface temperatures can exceed 140 degrees, and start prying up shingles. The work involves working on a slope with a nail gun, sealant, and the risk of damaging the shingles around the repair. The most common DIY failure we see is a homeowner who replaces one shingle but breaks the seal on four more. Call Dylan Pace and the crew at (650) 456-5615. We’ll show you photos of exactly what needs replacing before we touch anything.
FAQs
How long do CertainTeed shingles last in Woodland Hills? CertainTeed Landmark shingles typically last 22 to 28 years in Woodland Hills, slightly less on south-facing planes due to UV exposure. XT 25 installs tend to show age around 18 to 22 years. Actual lifespan depends heavily on attic ventilation and whether the roof was installed with proper underlayment.
Can a damaged CertainTeed shingle be repaired instead of replaced? A shingle with minor granule loss but no cracking can sometimes be resealed. A cracked, curled, or missing shingle should be replaced. A standard repair swapping out a handful of shingles is usually the most cost-effective fix in Woodland Hills. Call (650) 456-5615 for an exact quote, estimates are free.
How long does a CertainTeed shingle repair take? Most standard CertainTeed shingle repairs in Woodland Hills take 1 to 2 hours. If we discover rotted decking or failed underlayment, the job extends. We’ll give you a live arrival time before we come and text you before-and-after photos of the completed work.
Do you stock CertainTeed shingles on your truck? We carry common CertainTeed Landmark colors and can source less common blends within a few days. We also work with GAF and Owens Corning materials when a CertainTeed product is discontinued or unavailable.
