This page is for Santa Clarita homeowners who already have IKO shingles on their roof or are weighing IKO for a new roof. We cover full tear-offs, new construction, asphalt and architectural shingle installs, roof decking replacement, and flat roofing. You are not reading a brand brochure. You are reading what we see on IKO roofs across Valencia, Saugus, Canyon Country, Newhall, and Stevenson Ranch.

How IKO Products Fail – and How We Fix Them

Every shingle brand fails in its own way. IKO has specific patterns we have tracked across hundreds of Santa Clarita roofs, and knowing these patterns is the difference between a quick fix and a full replacement you did not need.

• IKO Cambridge granule loss on south-facing slopes. The Cambridge architectural line is common across Santa Clarita because it is affordable and looks sharp on Spanish and ranch-style homes. The problem is heat. On south and west facing slopes above Saugus and Canyon Country, the asphalt in the shingle’s top layer cures faster than the ceramic granules can stay bonded, so you get a steady drip of granules into the gutter and a roof that looks 20 years old at year 9. When we see this on more than 30 percent of the roof face, we recommend full replacement rather than patch work. Patching granule loss on Cambridge is throwing money at a roof that has already told you it is done.
• IKO Dynasty overdriven nails that pop through the shingle above. The Dynasty and Nordic lines have a thicker nail strip and a reinforced common bond, but if the crew that installed them fired nails at high PSI, the nail head sits proud and eventually cuts through the shingle above it. Roofing in Santa Clarita gets hammered by wind-driven rain coming through the Newhall Pass in winter, and a popped nail is a direct water path into the deck. Our fix on a full replacement is re-nailing at correct depth and pattern across the entire field, not just the visible pops.
• IKO Marathon algae streaking that masks real deck rot. The Marathon line is less common in Santa Clarita than Cambridge or Dynasty, but we see it on older homes in Newhall and parts of Valencia. The blue-green algae stains look cosmetic, and they usually are, but the same shaded, damp conditions that feed algae also soften the OSB decking underneath. On replacements we pull back shingles in the stained zones and probe the deck before we quote. If the deck is soft, that changes the price and we tell you before we start, not after.
• Improper IKO starter strip placement causing shingle blow-off at the eaves. IKO requires its starter strip offset from the first course in a specific pattern for the nail line to land correctly. When a crew uses a generic starter or aligns it wrong, the first course at the eave edge lifts in high wind. Santa Clarita gets sustained 40 mph gusts every fall. We see blow-off along the eave line on IKO roofs that are otherwise intact. A full replacement with correct IKO starter strip placement and six nails per shingle fixes the root cause.
• Flashing failure at IKO roof-to-wall transitions on stucco homes. Santa Clarita has thousands of stucco-sided homes, and the roof-to-wall line is where IKO systems fail most often when step flashing was skipped or under-driven. Water follows the wall, gets behind the shingle edge, and rots the top course of decking and the fascia. Every IKO replacement we quote includes new step flashing at every wall intersection and counterflashing where stucco meets the roof. It is not optional on our jobs.

Key takeaway: if your IKO roof is losing granules, lifting at the eaves, or showing water stains near walls, the failure is usually install-related or heat-related, not a defective shingle. That matters because the fix is in how the new roof goes on, not just which shingle you buy. Every estimate we hand you is one we’d be comfortable signing twice.

Our IKO Roof Replacement Process

Here is how an IKO replacement works with us, step by step. No wondering who is showing up, no invoice surprises at the end.

1. 1
   Call and schedule. You call (661) 219-7793. A live person answers, not a voicemail tree. We set a day and a live trackable arrival time, so you know when our truck pulls up.
2. 2
   Inspection and documentation. Dylan Pace or one of our techs walks the roof, checks decking condition, flashing, ventilation, and existing IKO shingle condition. We take before photos of everything we plan to touch and everything we don’t.
3. 3
   Written estimate with line items. We hand you a written price before any work starts. The number on the estimate is the number on the final invoice. If we find deck rot during tear-off, we show you photos, explain what changed, and get your approval before we spend another dollar.
4. 4
   Tear-off and prep. We remove the old IKO shingles, underlayment, and damaged decking. We re-deck with new OSB or plywood where needed. We replace all step flashing, pipe boots, and valley metal on every replacement.
5. 5
   Installation. IKO shingles go down with the correct starter strip, nail pattern, and spacing per IKO specs. If you want IKO’s higher-wind warranty, we note that and install to the upgraded standard.
6. 6
   Cleanup, photos, digital invoice. We clean up fully, send you after photos, and text you a digital invoice. Your replacement carries the manufacturer warranty plus our 365-Day Done Right Promise on workmanship, so anything we install wrong gets fixed free for a full year.

What IKO Roof Replacement Costs in Santa Clarita

Real numbers for the jobs we do most often. These are full tear-off and replacement ranges as of early 2026.

• IKO Cambridge replacement, 1,800 sq ft single-story: $11,500 to $14,800
• IKO Dynasty replacement, 2,400 sq ft two-story: $15,200 to $19,500
• IKO Nordic or other premium architectural, 3,000+ sq ft: $19,800 to $24,500
• Roof decking replacement (per 4×8 sheet): $85 to $140 installed
• Full flat roof replacement with IKO modified bitumen or TPO alternative: $13,000 to $21,000 depending on access and insulation

What moves the price: decking rot, roof pitch, number of valleys and wall intersections, current code requirements for ventilation and underlayment, and whether the old roof is one layer or two. Santa Clarita building codes now require specific attic ventilation ratios on reroofs, and that adds cost on homes built before 1990. We show every line item before you sign.
