How IKO Products Fail – and How We Fix Them

IKO makes a solid shingle, but every manufacturer has weak points, and we’ve seen enough IKO roofs across West Covina to know exactly where they show up. Here’s what we typically find when an IKO roof is due for replacement:

• Cambridge loss of granule adhesion (2010-2016 batches). We’ve torn off IKO Cambridge roofs in neighborhoods like Galster Hills and South Hills where the granules were shedding like a bad sunburn. The fiberglass mat is fine, but the asphalt layer didn’t hold its mineral coat. Once granule loss exposes the asphalt, UV breaks it down fast. On replacement, we use a heavier architectural shingle with better granule embedment, whether that’s a newer IKO Cambridge or a CertainTeed Landmark.
• Dynasty and Nordic seal strip delamination in valley heat. West Covina summers routinely hit 100 degrees, and IKO’s early seal strips on Dynasty could release and re-seal unevenly, leaving shingle edges lifted enough for wind to catch. We see this most on roofs with southern exposure where the decking expands and contracts hard. The fix isn’t resealing, it’s removing and replacing the affected slopes and checking the underlayment for heat damage underneath.
• Marathon and SuperPlus brittle cracking on older homes. The 3-tab IKO lines from the early 2000s are reaching end of life across West Covina right now. They get brittle, corners snap, and we find cracks along the nail line that let water through the fastener. If your home off Azusa Avenue or near Delhaven Park still has original 3-tab, you’re likely seeing granule build-up in gutters and occasional ceiling stains. A full replacement is almost always cheaper than chasing repeat repairs on a brittle deck.
• Insufficient attic ventilation accelerating IKO curl. This one isn’t IKO’s fault, but it kills IKO roofs on mid-century West Covina homes faster than anything else. Poor soffit-to-ridge airflow pushes attic temps past 140 degrees, which cooks the shingle from underneath. We see cupping and clawing concentrated along the hottest roof planes. When we replace, we address intake and exhaust ventilation as part of the job, or you’ll have the same problem on new shingles in eight years instead of twenty.
• Improper nailing on re-roofs done before 2012. A lot of West Covina homes got re-roofed during the 2000s boom by crews that overcounted on nail guns. We find IKO shingles nailed too high, outside the nail strip, or overdriven through the mat. That compromises wind rating and leaves shingles that slide or tear in the Santa Ana winds. Our replacement protocol is a full tear-off to inspect the decking, so we’re never installing new IKO over hidden nail failures.

Our IKO Roof Replacement Process

Every IKO replacement we do in West Covina follows the same sequence, and you’ll get photo documentation at each stage:

1. 1
   Roof read and deck inspection. We start with a full attic and roof-plane assessment. Dylan Pace personally walks every roof before quoting. We check decking condition, rafters, ventilation, and existing flashing, which is the metal stripping sealing chimneys, skylights, and sidewalls.
2. 2
   Written line-item quote before any work starts. You get a price for tear-off, decking repair if needed, underlayment, shingles, flashing, vents, and cleanup. That number doesn’t move unless hidden deck rot forces a change, and then you hear from us first.
3. 3
   Material decision. We go over your options honestly. If you want to stay with IKO, we recommend current Dynasty or Cambridge lines with proper ventilation upgrades. If another brand like Owens Corning Duration or CertainTeed Landmark makes more sense for your roof’s pitch and exposure, we tell you why.
4. 4
   Full tear-off and deck replacement. We strip to the deck, replace any rotted or delaminated sheathing, and inspect every fastener. In West Covina’s wind zones, we confirm nailing patterns match the manufacturer’s current spec.
5. 5
   Installation, flashing, and ventilation. New underlayment goes down, then the shingle system, then new or restored flashing at every penetration. We upgrade ventilation where the old roof was under-vented.
6. 6
   Photo documentation and final walkthrough. Before and after photos are part of every Crestview job through The Relay Standard. You’ll see exactly what was done, and you’ll have a digital invoice sent by text before we leave.

What IKO Roof Replacement Costs in West Covina

Here’s what IKO work actually costs in this market, based on the jobs we’ve quoted and completed across West Covina:

What moves the price: decking condition, roof pitch, number of penetrations (chimneys, vents, skylights), and whether you need ventilation work. A steep roof with three skylights near the West Covina hills costs more than a simple ranch off Cameron Avenue. Call (831) 777-6412 for an exact written quote, free.
