IKO Roofing Company in San Jose: What to Know First
IKO roof repair in San Jose typically runs $350 to $1,100 for common shingle and flashing work, with most repairs completed in a single visit. We’re an independent IKO service provider, which means we’re not tied to any one manufacturer’s script, and we give you a written price before a single shingle moves. If you own an IKO roof in San Jose and you’re seeing granule loss, curling shingles, or leaks around penetrations, this page will tell you exactly what’s happening up there and what it should cost to fix. Call (669) 274-0078 and a live person answers.
Greg Holloway, the owner of Tilehurst Roofing San Jose, has spent nearly two decades working on roofs across the South Bay, including plenty of IKO installations in neighborhoods from Willow Glen to Evergreen. Our techs know the difference between an IKO Cambridge and an IKO Nordic, and they know what each one does when San Jose’s wet winters and dry summers start working on it. You’ll get that knowledge before you spend a dollar.
How IKO Products Fail – and How We Fix Them
IKO makes a solid shingle, but every product line has its own failure patterns. Here’s what we see most often on San Jose roofs, and what we do about it.
- IKO Cambridge granule loss on south-facing slopes. San Jose’s summer sun is unkind to asphalt, and Cambridge shingles on unshaded southern exposures can shed granules faster than the rest of the roof. That granular grit in your gutters is the coating that protects the asphalt from UV breakdown. We inspect the shingle mat for exposed asphalt, then either spot-replace damaged courses or recommend full replacement if the loss is widespread. Waiting turns a $400 repair into a $14,000 re-roof.
- IKO Dynasty nail-line seal failures at the factory seal strip. Dynasty is IKO’s heavier laminated shingle, and when it’s installed in cooler weather or on a low-slope deck, the factory adhesive strip sometimes doesn’t fully activate. You’ll see shingle corners lifting on windy days and hear flapping. The fix is hand-sealing the affected shingles with the correct adhesive, not caulk from a hardware store. We’ve corrected this on dozens of San Jose homes where the original installer was long gone.
- IKO Nordic raised-profile cracking at the crown. Nordic is a dimensional shingle with a thicker exposure, and its raised profile can develop stress cracks at the crown after years of thermal cycling. San Jose’s diurnal temperature swings, hot afternoons and cool nights, accelerate this. Hairline cracks tell us water is working into the shingle mat. We replace cracked Nordic shingles individually when the surrounding courses are still sound.
- IKO Marathon flashing failures at pipe penetrations and valleys. Marathon is IKO’s value line, and the shingles themselves hold up fine. The weak point is almost always the installation details: pipe boot flashing that wasn’t replaced at the same time, valley metal that’s too narrow, or step flashing nailed through instead of over. We find these on Marathon roofs all over San Jose, and the repair is methodical: remove the failed flashing, install proper gauge metal, and re-lay the shingles so water sheds away from the penetration.
- IKO Armourshake wind-lift on exposed hillside homes. Armourshake mimics wood shake, and its cutout tabs catch wind more than a solid shingle. Homes in the East Foothills or off Communications Hill get hit harder by wind than the valley floor, and we see Armourshake shingles lifted or torn from those exposures. We inspect the nailing pattern, because at six nails per shingle and correct placement, these hold. At four nails or a high-nail pattern, they don’t. We’ll re-nail and re-seal to the correct spec.

Our IKO Roofing Company Process
- 1
You call, a person answers. Not a callback queue, not a voicemail that gets checked Monday. You reach a live person who takes your address and the basics. We schedule a time and show up in that window.
- 2
We do a full roof assessment, not just the spot you noticed. Our tech walks the entire roof surface, checks the flashing, drip edge, ridge cap, and underlayment where visible. If you have an IKO Cambridge or Dynasty roof, we know which slopes take the most sun and where the known stress points are. We also check the attic or crawlspace for decking water stains that tell us a leak has been running longer than you think.
- 3
We explain what we found and hand you a written price. You get the number before any work starts. If we recommend OEM IKO shingles, we say so. If a quality aftermarket component will do the job at a better price, we say that too and explain the difference. No change orders at the door.
- 4
We do the work clean. Tarps under the work area, magnetic nail sweep when we’re done, and the roof left looking like we matched the existing course pattern. Greg’s background running crews around San Jose means the crew knows how to work roofs in Santa Clara County’s freeze-free but wet winters, and how to handle tile and flat roof transitions that a shingle-only crew would walk past.
- 5
We test the repair before we leave. After the shingles are set and the flashing is sealed, we run water over the repaired area where practical and inspect from below. If it doesn’t shed water correctly, we re-work it before we pack up, not after you call back.
- 6
You get the guarantee in writing before the crew leaves. Every repair carries a written guarantee. If that repair fails inside the guarantee period, we come back and correct it at no charge under our 365-Day Done Right Promise.

AfterWhat IKO Roofing Company Costs in San Jose
Here’s what IKO roof repair actually costs in San Jose, based on the jobs we price and complete every month.
- Small shingle repair (3-8 shingles, no flashing work): $350 to $550
- Flashing repair around a pipe, vent, or skylight: $450 to $800
- Valley re-flashing with IKO shingle re-lay: $650 to $1,100
- South-facing slope granule-loss repair with spot shingle replacement: $500 to $900
- Full IKO re-roof on a typical 1,800-2,200 sq ft San Jose home: starts around $13,500 and runs up to $22,000 depending on decking condition, tear-off requirements, and which IKO line you choose
What moves the price is the scope of decking damage, whether the underlayment needs replacement (it often does on San Jose homes built before the mid-2000s), and the pitch of your roof. Steeper roofs cost more per square. Call (669) 274-0078 and we’ll give you the exact number for your roof in writing. Estimates are free and there’s no obligation.
Why San Jose Homeowners Call Tilehurst Roofing San Jose for IKO Work
We built Tilehurst Roofing San Jose for homeowners who’ve already been through a no-show contractor, a price that changed at the door, or a repair that failed within months. That’s the customer we understand best because it’s the customer Greg’s been answering calls from for almost twenty years. When you call us about your IKO roof, a live person picks up the phone. You get a written price before any work starts. Our techs are background-checked and uniformed, and they know IKO products specifically, which means they recognize the difference between a Cambridge granule loss issue and a Dynasty seal strip problem before they climb the ladder. We also work with six other major manufacturers, including GAF, Owens Corning, and CertainTeed, so if your roof would genuinely be better served by something other than an IKO product, we’ll tell you that straight. “Tell me what’s on your roof and I’ll tell you what it needs – straight answer, no guesswork.”
FAQs
IKO’s manufacturer warranty for materials remains intact regardless of who performs the repair, as long as the repair is done to code and doesn’t void the installation warranty conditions. Our repairs are done to IKO’s published installation specifications, which protects your material warranty. We’ll document the work with photos and a repair report you can keep for the manufacturer’s file if a claim is ever needed. For an exact assessment of where your roof stands, call (669) 274-0078.
IKO products have consistent distributor support in the Bay Area, so common lines like Cambridge and Dynasty in stock colors are typically available same week. Less common colors or the Nordic raised profile may take seven to ten days. We’ll tell you the actual timeline before you commit to any repair, and the written price stays the same even if the wait is longer than expected. Call (669) 274-0078 for availability on your specific line and color.
We can match most IKO colors using the manufacturer’s current color charts, and we’ll always show you the shingle sample next to your roof before we start. In cases where the original color is discontinued or the existing roof has heavy UV fade, we’ll be honest about how close the match will be and where the repair will sit visibly. Sometimes the better move is replacing a larger contiguous section so the transition looks intentional. We’ll walk you through it and you make the call.
We handle IKO’s modified bitumen and TPO systems, which are common on San Jose homes with flat roof sections over garages and additions. Those systems fail differently than shingles: seam separations, ponding around drains, and deteriorated flashing at the wall-to-roof transitions are the usual culprits. We’ll inspect the existing membrane, identify the failure point, and quote you a repair that addresses the actual leak path, not just the visible spot. Call (669) 274-0078 to schedule the inspection.
Every repair we perform comes with a written guarantee that covers the specific repair work we completed. If the repaired area fails inside the guarantee period, we return within the 365-Day Done Right Promise window and correct it at no charge. The guarantee is printed and in your hands before the crew leaves your driveway, not emailed later. That’s the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing, come back if it fails. We stand behind it.
If your IKO roof is showing signs of trouble, or you just want a straight answer about what’s up there, call (669) 274-0078. A live person answers, and your estimate is free.
