IKO Roofing Company in San Antonio: What to Know First

We’re an independent IKO service provider in San Antonio, and we repair and replace IKO shingle roofs throughout Bexar County. Most IKO repair calls we handle are diagnosed and fixed within one to three days, depending on what we find when we get on the roof. On pricing, we don’t do vague estimates – every IKO job starts with a written price before any work begins, and that number doesn’t change unless you change the scope.

Call (254) 276-4369

If you own an IKO roof and you’re seeing granule loss, curling shingles, or leaks around flashing, this page explains what’s actually happening and what it costs to fix. For the short version: call (254) 276-4369 and we’ll talk through what you’re seeing. Grant Whitlock and our San Antonio crew work on IKO roofs regularly, and we’ll tell you straight if a repair makes sense or if replacement is the smarter money.

How IKO Products Fail – and How We Fix Them

IKO makes a solid shingle, but every manufacturer has patterns. Here are the failure modes we see most on San Antonio IKO roofs, and what we do about them.

• IKO Cambridge granule shedding within the first decade. San Antonio’s heat cycles – brutal sun, then sudden downpours – accelerate granule loss on IKO Cambridge shingles, especially on south-facing slopes. Granules protect the asphalt from UV breakdown; once they’re gone, the shingle dries out and cracks. We inspect for uneven granule distribution, and on roofs under 15 years old, we’ll spot-replace affected shingles with IKO-matched products where the slope still has life.
• IKO Dynasty seal strip failures on steep pitches. On steep roofs, IKO Dynasty shingles sometimes fail to seal if they were installed in cooler weather or nailed outside the nail strip. In San Antonio’s wind-driven storms, an unsealed shingle lifts and breaks. We look for “flapping” rows after storms, and the fix is typically re-sealing with adhesive or hand-nailing the affected row – not replacing whole sections.
• Valley flashing leaks on older IKO Nordic installs. Nordic was IKO’s premium architectural line, and the shingles hold up well. The weak point is usually the valley flashing – open valleys with exposed metal that corrodes over time in our high humidity and occasional hail. We’re replacing valley metal and re-flashing these junctions regularly across Alamo Heights and Terrell Hills, where older IKO roofs are common.
• Decking rot under IKO shingles due to inadequate ventilation. IKO shingles don’t fail on their own as often as they fail because the attic underneath is cooking. San Antonio attics hit 140°F in July. Without ridge and soffit ventilation, heat and moisture get trapped, the decking swells and rots, and the IKO shingles fail prematurely from the bottom up. Before we ever re-shingle an IKO roof, we check ventilation.
• Hail damage on IKO Marathon and Cambridge lines. IKO shingles use fiberglass matting, which means hail impacts often show as soft spots rather than visible cracks. We’ve walked roofs after storms where the homeowner saw no damage from the ground, but the IKO Marathon shingles had lost mat integrity at impact points. We document it with photos, mark the affected zones, and work with you on a repair scope that insurance adjusters can verify.

One thing we won’t do is slap generic shingles over IKO and call it a match. IKO has specific color lines and profile heights, and a mismatched patch looks like a scar. We use IKO shingles where the roof is under warranty or the color line is active, and we’ll tell you honestly when a different manufacturer’s shingle is a better fit for the slope and exposure.
