How IKO Products Fail – and How We Fix Them

• IKO Cambridge granule shedding within the first 5 years. We see this constantly across San Antonio’s older subdivisions like Woodlawn Lake and Jefferson. The Cambridge line’s asphalt blend is more UV-sensitive than competitors, and our sun doesn’t forgive. The granules end up in gutters while the underlying mat starts degrading. Fix: full tear-off and replacement rather than spot repair, because once granule loss is visible from the ground, the shingle is past saving.
• IKO Marathon curling at the eaves and rakes. This shows up most on homes in Alamo Heights and Terrell Hills where attic ventilation was never upgraded after the original 1990s build. The Marathon three-tab traps heat at the roof’s lower edges, the shingles cup upward, and wind-driven rain gets underneath. Fix: we replace the roof and correct the ventilation at the same time, because a new IKO roof with the same old soffit and ridge vent setup will curl again.
• IKO Dynasty nail-line tearing in high-wind years. The Dynasty line is a solid architectural shingle, but installers who nailed high during original construction left a strip of shingle above the nail line with no fastener. After a few spring storm seasons in San Antonio, those areas flap and tear even when the shingle itself still has life. Fix: full replacement with nails placed in the manufacturer-specified nailing zone, verified by photo before we cover anything.
• IKO Nordic shingle blow-off on low-slope sections. San Antonio homes with porch roofs or carports under 3:12 pitch should never have gotten standard shingles, but plenty did. Nordic, like any dimensional shingle, lifts in our spring microbursts when installed on low slope without proper underlayment. Fix: we tear back to decking, install ice-and-water shield or a self-adhered base, and only then lay the new shingles so the next 15 years of March winds don’t repeat the problem.
• IKO FastLock seal strip failure on south-facing slopes. The sealant strip on IKO shingles, which bonds the overlapping shingles together, can fail on south-facing roof planes after years of direct San Antonio heat. The shingles look fine but lift like pages in a book. Fix: roof replacement because resealing individual shingles on a whole slope costs more per square foot than replacement and won’t hold evenly across the plane.

Our IKO Roof Replacement Process

Here’s how a typical IKO replacement goes when you call Crestview Roofing Co San Antonio:

1. 1
   The call. A live person answers. You tell us what you’re seeing, and we set a time for an inspection that works around your schedule.
2. 2
   The inspection and written estimate. Dylan Pace or one of our lead techs walks the roof, checks the decking, the flashing, the existing IKO shingle condition, and the attic ventilation. You get a written price before any work starts. The number on the page is the number on the invoice.
3. 3
   The parts and materials decision. We discuss whether to stay with IKO or move to GAF, Owens Corning, or CertainTeed. If you want to stay with IKO, we order the exact line and color that matches your warranty needs. No surprise substitutions.
4. 4
   Teardown and decking inspection. We strip to bare decking. If any plywood or OSB is rotted, we show you photos before we touch it and quote the decking replacement separately, before the work happens.
5. 5
   Installation with photo proof. We install the new shingles and underlayment, shoot before-and-after photos at every stage, and document the nailing pattern so you can see the work was done to spec.
6. 6
   Final walkthrough and written guarantee. We walk the finished roof with you, send a digital invoice by text, and hand you the 365-Day Done Right Promise in writing. If anything fails within a year, we come back free.

What IKO Roof Replacement Costs in San Antonio

Most IKO roof replacements in San Antonio fall between $8,500 and $16,500, with the average landing around $11,000 for a 1,800 to 2,200 square foot single-story home. A straightforward IKO Cambridge tear-off and replacement on a simple gable roof starts near the low end. A two-story home with steep pitch, multiple valleys, or IKO Nordic on low-slope sections pushes toward the high end. Decking replacement adds $2 to $4 per square foot where the old plywood is rotted or soft. The biggest price movers are roof complexity, decking condition, and whether we’re correcting ventilation problems the original builder skipped. Call (361) 209-8857 and we’ll give you a written quote based on your actual roof, not a square-footage guess.

Why San Antonio Homeowners Call Crestview Roofing Co San Antonio for IKO Work

Because we put every promise in writing before the first shingle comes off. Our 365-Day Done Right Promise covers every replacement for a full year, including a free second visit if anything fails. That’s not a verbal assurance, it’s a written guarantee included with every job at no extra cost. We work with IKO, GAF, Owens Corning, and CertainTeed, so if an IKO line isn’t the right match for your roof’s pitch or sun exposure, we’ll tell you instead of selling you what we happen to have in the warehouse. You’ll know exactly who’s arriving before they pull into your driveway, you’ll get a live arrival time you can track, and you’ll see photo proof of the work before and after. Every job, every time. As Dylan Pace puts it: every promise we make goes in writing, because a handshake doesn’t keep water out.
