IKO Roof Inspection in Fresno: What to Know First
An IKO roof inspection in Fresno typically runs $195 to $350 for a full assessment, and we complete most inspections within 24 to 48 hours of your call. That price includes a written report with photos, specific repair recommendations, and a line-item quote before any work starts. We’re an independent IKO service provider, not a manufacturer affiliate, which means we report what we actually see rather than what protects a warranty claim.
This page is for Fresno homeowners who own IKO shingles and need a straight answer about what’s happening on their roof. If you’ve spotted granule loss in your gutters, a section lifting after wind, or staining on ceilings below the roof, call (559) 785-2160 and we’ll schedule the inspection.
How IKO Products Fail – and How We Fix Them
IKO makes solid shingles when installed correctly, but every product line has its own failure patterns. Here’s what we see on Fresno roofs, naming the specific series where it matters most:
- Cambridge granule shedding at the 12-15 year mark. The Cambridge line, IKO’s most common architectural shingle in Fresno, tends to release granules faster than competitors once the roof passes a decade in Valley sun. The cause is predictable: 100-degree summers bake the asphalt and the embedded granules lose their grip. We document the percentage of granule loss across each slope, because a 30% loss means different things on a south-facing plane versus a shaded north plane. If the loss is localized to one slope, we’ll quote a targeted repair instead of a full replacement.
- Nordic and Crowne Slate curling at the corners. These thicker, higher-profile IKO lines look great on Fresno Craftsman homes, but the heavier construction means corner-lift happens early if the installers over-nailed. Curling corners catch wind, and once wind gets under a shingle in a Fresno spring gust, it starts a tear pattern that only accelerates. We inspect nail placement, not just shingle appearance, because the curl is the symptom. The fix is often resealing with a manufacturer-approved adhesive, not a full reroof.
- Marathon and Dynasty sealant failure during the first Fresno heat wave after install. IKO’s sealant strips activate with heat, but if the roof went on during a cooler stretch and never got a good activation cycle, the shingle tabs don’t bond. A mild fall install followed by a cool winter can leave tabs unsealed until the next June, and by then wind has already flapped them. We check for unsealed tabs on any IKO roof installed within the last 18 months, because this is the cheapest fix we catch: resealing while the shingles are still pliable beats replacing wind-torn sections later.
- Valley and ridge granule loss on Cambridge and Dynasty, caused by Fresno’s dust and pollen loading. Valley lines take more water than any other part of the roof, and Fresno’s airborne grit acts like sandpaper during winter rains. IKO shingles in valleys lose granules in streaks that indicate exactly where water moves fastest. We trace those streaks and check the flashing beneath, because valley failure is rarely just the shingle: it’s the underlayment under it. The fix often means new metal valley flashing plus shingle replacement, not just patching the surface.
- Improper drip edge clearance on IKO’s lighter-weight lines, like the Marathon line. IKO’s three-tab Marathon is thinner than its architectural siblings, and on Fresno homes with older original drip edge, the shingle overhang can be wrong. Too little overhang lets water curl back under; too much leaves a flapping edge that breaks off in wind. We measure the overhang at every eave during inspection, because it’s a 30-second check that prevents thousands in water damage later.

Our IKO Roof Inspection Process
Here’s how an IKO inspection works when you call Brennan Roofing Co Fresno:
- 1
You call (559) 785-2160, a live person answers. We get your address, the age of the roof if you know it, and what you’ve been seeing: granules, leaks, lifting shingles. No voicemail, no callback queue.
- 2
We schedule a window and a technician shows up in uniform on time. Same process on every job, no exceptions. Your tech is background-checked and will carry a written work order with your name, your price, and your inspection scope.
- 3
The inspection covers every plane, the flashing, the underlayment access points, and the attic if accessible. On IKO roofs, we pay special attention to the sealant strip bond, granule loss percentages, and any sign of corner lift or valley streaking.
- 4
We document everything in a written report with photos. You get specific findings, not vague warnings: which slope, which shingle line, what percentage of loss, what the cause is, and what the fix will cost.
- 5
The price goes on paper before any work starts. If you need repairs, the price doesn’t move at the door. If you need a full replacement, the same written-price discipline applies.
- 6
Every repair or replacement gets the 365-Day Done Right Promise. If it fails within a year, we come back free. That’s in writing.

AfterWhat IKO Roof Inspection Costs in Fresno
Here’s what you can expect to pay in the Fresno market for IKO-specific roof inspection work:
- Full IKO roof inspection with written report: $195 to $350, depending on home size and roof complexity. A single-story rancher in Clovis or the Tower District lands at the lower end; a two-story with steep pitches and multiple valleys lands higher.
- Targeted inspection of one problem area, like a valley or a ridge: $125 to $200. This makes sense when you already know where the leak is and just need confirmation and a repair quote.
- Inspection plus minor IKO shingle repair, like resealing lifted tabs or replacing a small run: $350 to $750, all in.
- Inspection plus valley reflashing and shingle replacement: $900 to $2,200, depending on valley length and whether the decking underneath is sound.
What moves the price: roof pitch (steeper costs more for safety equipment and labor time), the number of valleys, whether the attic is accessible, and the age of your IKO shingles (older means more brittle, which means we quote more care and more time). Call (559) 785-2160 for an exact written quote. Estimates are free.
Why Fresno Homeowners Call Brennan Roofing Co Fresno for IKO Work
Fresno homeowners don’t call us because we’re the cheapest. They call us because we’re the most accountable, and IKO roofs are exactly where accountability matters. If a roofer no-shows on an IKO roof with a failing sealant strip, the roof keeps degrading while the homeowner waits. If a tech shows up who’s never touched a Cambridge shingle, he’ll waste your money replacing shingles when the real issue is the flashing underneath.
We operate under the Garrison Standard. That means a written price before any work starts, every time. A background-checked uniformed technician on your roof, not a day-laborer you’ve never met. A live person answering the phone when you call, around the clock. And when we finish, you get the 365-Day Done Right Promise in writing, a full-year guarantee on every repair and installation, with a free return visit if it fails. We also install GAF, Owens Corning, and CertainTeed, so if your IKO roof is beyond repair, we’ll give you straight options across brands instead of trying to sell you whatever we have in the yard.
Tell me what you’re seeing and I’ll tell you what it actually means.
FAQs
No. An inspection by an independent contractor does not void your IKO warranty. IKO’s warranty covers manufacturing defects, not installation or weather damage. Our inspection documents what we find, and if the damage is a manufacturing defect, we’ll tell you how to file a claim. If it’s installation error or Fresno weather, we’ll quote the fix. Either way, the inspection itself doesn’t touch your warranty. Call (559) 785-2160 if you want us to check before you file.
In most Fresno cases, yes. IKO’s Cambridge and Dynasty lines are widely stocked in the Valley, so color matching is usually possible if your roof is under 10 years old. Older roofs that have faded will show a visible patch no matter what we do, and we’ll tell you that before you approve any work. We’d rather be straight about the patch than send you a bill for something that you’ll notice every time you pull into the driveway.
If granule loss is under 15% and there’s no decking damage, repair usually makes sense. If multiple slopes show curling, unsealed tabs, or granule loss over 30%, replacement starts to be the better financial call, because you’re just buying time with repairs. The decision depends on how much life the decking and underlayment have left. We’ll show you the numbers either way, in writing, before any work starts. Call (559) 785-2160 for that breakdown.
Most inspections are scheduled within 24 to 48 hours, and the inspection itself takes about an hour for a standard single-story home. Larger two-story homes or steep roofs take longer, and we’ll tell you that when you schedule. The written report goes to you the same day the inspection is done.
You’ll get a line-item written quote for every finding, and the price doesn’t move at the door. If you approve the repair, it’s covered by the 365-Day Done Right Promise. If you don’t, you keep the report and you’re under no pressure to use us for anything. Call (559) 785-2160 and you’ll see how this works, in person, before you spend a dollar.
