IKO Roof Repair in San Antonio: What to Know First
IKO roof repair in San Antonio typically runs between $350 and $1,800 depending on what failed, and most repairs take one visit to complete. We’re an independent IKO roof repair contractor serving San Antonio, not an authorized IKO dealer, which means we can tell you straight what the shingle is doing and what it actually costs to fix. We work on IKO Cambridge, Dynasty, Nordic, and Marathon lines all over Bexar County.
If you own an IKO roof and you’ve spotted a leak, lifted shingles, or granule loss in a gutter, you’re in the right place. Call (254) 276-4369 and we’ll walk through what you’re seeing. The estimate is free, and the price we quote is the price you’ll pay.
Key Takeaways
- IKO Cambridge and Dynasty shingles are common in San Antonio, and each fails in specific ways we can identify on sight.
- Most IKO repairs run $350 to $1,800, with the final number depending on decking damage and how much flashing needs rework.
- Every repair gets a 365-Day Done Right Promise in writing, plus a free second visit if the fix doesn’t hold.
- We send a technician’s name and photo before anyone knocks on your door.

How IKO Products Fail – and How We Fix Them
IKO makes a solid shingle, but San Antonio’s heat and storm cycles expose specific weak points. Here’s what we actually see on IKO roofs in this city:
- Cambridge seal delamination in high-heat zones. IKO Cambridge is the most common IKO line we repair in San Antonio, and on roofs with poor ventilation we regularly find the seal strip has let go, leaving shingles flapping. This isn’t always wind damage. Sometimes the attic heat degrades the seal before its time. We replace the lifted shingles, then check whether the attic ventilation is the real culprit before we call the job done.
- Dynasty nail-line tears after hail. IKO Dynasty is a heavier shingle, but the nail zone sits in the same place as every other shingle. When Bexar County gets the kind of hail we saw north of Loop 1604, nail lines tear and shingles slide. We replace the torn run, and if the decking below shows impact bruising we document that for your insurance file.
- Marathon granule loss on low-slope sections. IKO Marathon is more common on reroofs of older San Antonio ranch homes, and on lower slopes the granules wear faster. The symptom is sand-like granule piles at the gutter downspout. When we see that, we check the slope against IKO’s own specs. Low slope plus Marathon sometimes means the shingle isn’t rated for that pitch, and we’ll tell you if patching is just buying time or if the section needs a different product.
- Valley flashing failures on IKO Nordic installs. Alamo Heights and Terrell Hills have a lot of older homes with IKO Nordic roofs and closed-cut valleys. The shingle overlay in the valley is the first thing to crack there, because that’s where water sheets during a storm. We open the valley, replace the flashing if the original installer reused it, and reweave the shingles to match the existing pattern.
- Vent boot rot around IKO Cambridge flashing. This isn’t really an IKO problem, but we see it more on IKO Cambridge roofs because the shingle holds so much granule texture it hides the actual leak point. The pipe boot underneath fails, water runs under the Cambridge shingle, and by the time you see a ceiling stain the decking around the pipe is already soft. We replace the boot, dry the area, and patch any decking that’s gone before replacing the shingles.
Our IKO Roof Repair Process
- 1
You call or book. A live person answers. We ask what you’re seeing, get your address, and schedule a time. Before the technician leaves the shop, we text you their name and photo.
- 2
The inspection. The technician arrives in a marked uniform, badges at the door with a photo ID, and walks you through what we’re checking before we get on the roof. We inspect the suspect area and the surrounding field, looking for what actually caused the failure, not just the visible symptom.
- 3
The diagnosis and written price. We explain in plain English what failed, why, and what it takes to fix it right. Then we hand you a written price. No work starts until you approve it.
- 4
The repair. We decide between OEM IKO shingles and quality aftermarket that matches in weight, color, and profile. If your IKO shingle is discontinued or the color lot doesn’t match, we’ll say so and show you options. We use matching underlayment, the right nail pattern per IKO’s install specs, and proper flashing technique at the penetrations.
- 5
The test and documentation. We run water on the repair if possible, check the underside for daylight, and photograph the finished work from the roof and the ground. You get the photos and the written guarantee before we leave.

AfterWhat IKO Roof Repair Costs in San Antonio
Here’s what IKO roof repair typically runs in San Antonio, based on what we’ve fixed across the city:
| Repair Type | Typical Range |
|---|---|
| Shingle replacement (Cambridge, Dynasty, Marathon) | $350 – $750 |
| Leak repair with penetrated flashing | $500 – $1,100 |
| Vent boot replacement | $400 – $800 |
| Valley rework and shingle weave | $700 – $1,400 |
| Flat roof patch with IKO roll products | $450 – $900 |
| Decking repair with shingle replacement | $800 – $1,800 |
What moves the price is decking damage, roof pitch, and whether we’re matching an IKO color lot that’s still active. Steeper roofs cost more because the work takes longer and safety setup is different. A full roof replacement is a separate conversation, and we’ll tell you honestly if that’s where the math points. Call (254) 276-4369 for your exact number. Estimates are free, and the written price is the price.
Why San Antonio Homeowners Call Mercer Roofing Co San Antonio for IKO Work
Grant Whitlock founded this location because he kept hearing the same thing from homeowners: the last roofer was a stranger who showed up unannounced and left a number they couldn’t trust. We run this company differently. Every IKO repair starts with a name and a photo sent before we arrive. The technician at your door is background-checked, identity-verified, and wearing a photo ID, per the Threshold Verified standard. That’s not a promise, it’s the way Mercer Roofing Co San Antonio operates.
Every IKO repair includes a written guarantee and the 365-Day Done Right Promise. If the fix doesn’t hold within a year, we make it right. And while IKO is our focus here, we also work with GAF, Owens Corning, and CertainTeed every week, so if your roof has mixed brands from a previous repair, we can match them. A roof shouldn’t be something you worry about – that’s our job.
FAQs
No. As an independent IKO service provider, our repairs don’t void your original IKO warranty, but we always document materials, dates, and photos so you have a record for any future claim. The one thing that does void IKO warranties is repair work done incorrectly: wrong fasteners, wrong underlayment, or ventilation changes that trap heat. We work to IKO’s published install specs on every job, because a warranty you can actually use matters more than a patch that gets you to next year.
Most IKO Cambridge, Dynasty, and Marathon color lines are still active, and we can source exact matches through our supplier network in San Antonio. If your lot is discontinued or the roof has aged enough that new shingles will stand out, we’ll be upfront about it before you spend money. The last thing we want is a patch job that looks like a patch. Call (254) 276-4369 and we’ll check your specific shingle.
The answer depends on the age of the shingle and the number of failed areas. A single leak or a few lifted shingles on a roof under 15 years old is usually a clear repair. Widespread granule loss, curling across multiple slopes, or decking that’s wet in more than one room usually points toward replacement. We’ll tell you what we’d do if it were our house, and we don’t get paid differently for saying “replace” versus “repair.”
We answer the phone live, 24/7, and we’ll get a technician scheduled as quickly as our current queue allows. We don’t promise same-day arrival because we don’t want to make a promise the schedule can’t keep. What we can promise: we’ll give you a straight answer on timing when you call, and if the leak is active, we’ll tell you how to protect the interior until we get there. Call (254) 276-4369 and we’ll take it from there.
