IKO Roofing: The San Antonio Owner’s Guide
We stock and install IKO-compatible roofing materials across San Antonio, with most roof repairs running $400 – $1,800 and full IKO roof replacements between $8,000 – $20,000 depending on square footage, pitch, and tear-off requirements. Most owners discover an IKO roofing failure the hard way: a water stain on the ceiling after a storm, granules collecting in the gutters, or a shingle that peeled back during a March wind event. If you’re seeing any of that, you’re in the right place. We’ll walk you through exactly what’s failing, what it costs to fix in San Antonio, and whether it’s a job for you or for our crew.
One thing up front: Mason Remodeling Co San Antonio is an independent service provider. We’re not affiliated with IKO, but we install and repair IKO product lines regularly because they’re common on San Antonio roofs, especially in neighborhoods built out in the 1990s and 2000s where IKO Cambridge and Marathon shingles went on heavily. We also carry materials for KraftMaid, Cambria, and Silestone, but when a roof is shedding granules or lifting at the edges, IKO is the brand we see most often on the work order.
Which IKO Models This Applies To
In San Antonio, you’ll most often find IKO Cambridge architectural shingles, IKO Marathon, IKO Dynasty, and on higher-end homes, IKO Nordic performance shingles. Each line has specific dimensional specs that matter if you’re patching rather than replacing: Cambridge runs roughly 13¼” x 39⅜” with a 5⅝” exposure, while Dynasty comes in at the same exposure but with a heavier, high-definition granule blend that changes the color-match calculation on a repair.
When we replace damaged IKO shingles mid-roof, we match by measuring the exposed tab length and checking the manufacturer’s code printed on the underside of a lifted shingle. That code tells us the plant, batch, and color blend. Here’s the gotcha most San Antonio homeowners don’t know: IKO color lots shift subtly between production runs, especially on the earthy tones like Weatherwood and Dual Black. A shingle from a different batch can look fine on the ground and noticeably mismatched once it’s on the roof in full sun. We keep common IKO colors stocked and will pull from the closest match rather than whatever’s on the shelf.
OEM IKO shingles are the safe default for warranty continuity and color match. Quality aftermarket equivalents exist, but for mid-roof patching we rarely recommend them on IKO systems because the dimensional profile and adhesive strip alignment differ just enough to create a seam that lifts in high wind. For full replacements, we quote IKO product directly along with GAF, CertainTeed, and Owens Corning alternatives, because the choice should come down to your budget and warranty preference, not what one supplier happens to stock.
Styles & brands we work with
Signs Your IKO Roofing Is Failing
- Granules in the gutters or downspouts. IKO shingles shed granules as they age, especially on San Antonio’s west-facing slopes where UV exposure is brutal. By the time you see bare asphalt patches, the shingle has lost most of its protective layer and is accelerating toward failure.
- Shingles lifting or flapping at the edges. The adhesive strip on IKO shingles can fail before the shingle itself does, particularly after the freeze-thaw cycles we get in January and February. If you see shingles standing up after a wind event, the seal is gone and water can drive underneath.
- Curling or cupping shingles. San Antonio attic temperatures hit 130°F routinely in August. When the attic isn’t ventilated correctly, IKO shingles curl at the corners and pull the nail heads loose. This is a ventilation problem masquerading as a shingle problem.
- Water staining on ceilings or along exterior walls. By the time water shows up inside, the underlayment or a flashing point has already failed. IKO shingles can look intact while the roof is leaking at a valley, pipe boot, or chimney flashing.
- Missing shingles after a storm. San Antonio gets hail and straight-line winds every spring. Missing IKO shingles may be covered by insurance, but the replacement shingle has to be color-matched and sealed correctly or you’ll get a recurring problem at the patch site.

AfterReplacement Cost & What’s Included
If you’re patching IKO shingles in San Antonio, plan on $400 – $1,800 depending on how many squares are damaged and how steep the roof is. Targeting repairs on a single story walkable roof runs $400 – $900. Same repair on a two-story 8/12 pitch with tear-off of damaged underlayment pushes toward $1,500 – $1,800. A full IKO roof replacement in San Antonio typically runs $8,000 – $20,000, with most average ranch homes landing around $12,000 – $15,000.
What drives the range: square footage of the roof, number of layers being torn off, decking repair if water has sat, flashing replacement at valleys and penetrations, and whether you’re upgrading the underlayment. We deliver a written price before any work starts, on every IKO job, no exceptions. The written quote includes the shingle line item, underlayment, flashing, disposal, labor, and any permit fees. No verbal estimate that grows later. Our installation work is covered by the 365-Day Done Right Promise: if something isn’t right within a year of completion, we return and fix it at no cost. No dispute process, no conditions.
DIY or Call Us?
Here’s the honest split. If you just need to know whether your IKO shingles are failing, you can check a few things from the ground or a ladder without getting on the roof: look for granules in the gutters, shingles lifting at the corners, or bare spots visible from the yard. Take photos with your phone and note which slope of the roof shows the damage. That’s useful information when you call us.
What we don’t recommend is getting on the roof to replace IKO shingles yourself. San Antonio roofs are steep, hot, and the shingles get slick with morning dew and moss. A roofer with experience knows how to walk a 8/12 pitch without breaking tiles or falling. We also see a lot of DIY patches where the adhesive strip never seals because the shingle was nailed in the wrong spot or the surface wasn’t prepped. That patch leaks within a year. If you’re at the point of pulling shingles, call (254) 269-5071 and let us handle it. The estimate is free.
FAQs
IKO architectural shingles like Cambridge typically last 15 – 20 years in San Antonio’s climate, which is shorter than in cooler regions because UV exposure and attic heat accelerate granule loss and sealant breakdown. If your IKO roof is past year 15 and showing two or more of the failure signs above, start budgeting for replacement rather than patching. Call (254) 269-5071 for an exact assessment of your roof’s remaining life.
Yes, isolated damage can be repaired for $400 – $1,800 when the surrounding shingles are still sealed and the underlayment is intact. If the shingles are curling across multiple slopes, the adhesive strips have failed in broad areas, or you’re seeing leaks in more than one room, patching becomes a temporary bandage on a system that’s already reached end of life. We’ll tell you honestly which situation you’re in before we quote anything.
A targeted shingle patch on an IKO roof takes 2 – 4 hours on site. A full tear-off and replacement takes 1 – 3 days for most San Antonio homes, depending on roof size, tear-off layers, and whether decking needs to be replaced. We schedule crews by name and photo so you know exactly who’s arriving and when, and a live person answers the phone around the clock if your timeline changes.
Our San Antonio crews keep common IKO Cambridge colors stocked on the truck for repairs, including Weatherwood, Dual Black, and Charcoal Gray. Less common Dynasty or Nordic colors may require a supplier run, which we confirm before we schedule so you’re not waiting on a crew with no materials. Call (254) 269-5071 with your shingle color and we’ll check stock while you’re on the phone.
Know who’s coming, know what it costs, know it’s covered; that’s the whole job before the job starts.
