IKO Roofing Company in San Francisco: What to Know First

IKO roof repair and replacement in San Francisco typically runs $450 – $1,200 for targeted repairs and $14,000 – $28,000 for a full tear-off and re-roof on a standard single-family home, depending on slope, decking condition, and the IKO line you choose. Most IKO repair work we handle is completed within one to three days once we’re on the schedule. We’re an independent IKO service provider, not a manufacturer-authorized dealer, which matters because we recommend what the roof actually needs rather than what protects a brand relationship.

How IKO Products Fail – and How We Fix Them

IKO makes a solid shingle, and plenty of San Francisco homes wear them well. But every manufacturer has its patterns, and after years of working on IKO roofs from the Sunset to Bernal Heights, we know what to look for. Here are the failure modes we see most often on IKO products in San Francisco, along with what we do about each one.

• Cambridge granule shedding on south-facing slopes. IKO Cambridge shingles carry a heavier granule load than some competitors, but San Francisco’s constant fog-to-sun cycling can loosen granules early, especially on slopes with direct afternoon exposure. You’ll see grit in the gutters and a thinning, patchy look on the shingle face. Granule loss is the first sign the asphalt layer is degrading. We inspect the affected slope, and if the mat is still sound, we’ll document the condition and advise on replacement timing. If the underlying mat is cracking, we replace the affected slopes or the full roof, whichever the decking and budget support.
• Dynasty high-wind lifting at eaves and rakes. IKO Dynasty is a heavier, architectural shingle rated for higher wind speeds, but the rating only holds if the seal strip fully adheres. In San Francisco’s wind corridors, particularly the outer Richmond, the Sunset, and Twin Peaks, we regularly find shingles that never fully sealed because of moisture or cold temperatures during installation. The fix is careful: we hand-seal lifted tabs with the correct adhesive and verify the nailing pattern underneath is actually holding. If the shingle was high-nailed, we replace it, because adhesive alone will not correct a bad nail job.
• Nordic self-sealing failures on steep Victorian pitches. IKO Nordic is a performance shingle designed for steep slopes and severe weather, but on San Francisco Victorians with pitches over 9/12, we’ve seen seal strip adhesion fail when the original installer did not clean the surface before laying. The result is shingles that look fine from the ground but lift in a stiff wind. On those roofs, we’ll remove and reset shingles in the affected areas, and we check the entire ridge and eave lines, because partial seal failure rarely happens in isolation.
• Flashing rot at IKO valley and chimney transitions. The shingle brand matters less than the flashing, and in San Francisco, the marine air accelerates corrosion on galvanized flashing installed under IKO shingles. We see rust-through at valleys and around chimneys long before the shingles themselves fail. We replace the flashing with a higher-gauge material or aluminum where appropriate, and we replace any IKO shingles that were damaged by the old flashing leaks. This is a pattern we see across all brands, but on older IKO installs around the city, it’s a frequent caller.
• IKO flat-roof membrane seam splitting in fog-heavy neighborhoods. San Francisco’s flat-roof stock is huge, and IKO has a presence in that market with torch-down and self-adhered membranes. The seams are the weak point. In neighborhoods like the Richmond and the Marina, where the fog sits for hours, constant expansion and contraction splits seams that were not fully bonded at install. We identify the failed seam, dry it out properly, and re-weld or patch it with a compatible membrane. A good torch-down repair on an IKO flat roof should last years, provided the seam work is actually done, not just sealed over.

Our IKO Roofing Company Process

Every IKO job we run in San Francisco follows the same sequence. It’s boring on purpose, because the roof should hold and you should know exactly what happened on it.

1. 1
   Call and inspection. You call (831) 318-8819, and a live person answers. We schedule a time that works for you, and a background-checked, uniformed technician shows up inside the promised window. Travis Oakley reads every IKO roof the same way: he walks the whole surface, not just the leak area. He’ll tell you what needs work now, what can wait two seasons, and what a hungrier contractor might oversell.
2. 2
   Written price before any work starts. After the inspection, we put the job on paper. The price includes parts, labor, and any decking or flashing work we can see from the surface. It does not change when we show up to do the work, unless we open the roof and find structural damage we could not have seen. In that case, we stop, show you photos, and give you a new written price for the additional work. No work begins until you approve it.
3. 3
   Parts decision: OEM vs. quality aftermarket. For IKO products that are still in production, we use IKO components where the manufacturer’s compatibility matters: matching shingle colors, custom ridge caps, and IKO flat-roof membranes. For underlayment, fasteners, and flashing, we use materials we trust across all brands. If IKO has discontinued a color or line, we’ll show you the closest match from IKO’s current catalog, or we’ll discuss a different manufacturer line that visually and functionally matches. We don’t substitute without your sign-off.
4. 4
   The repair or replacement. We strip what needs stripping, repair or replace decking sections as needed, install underlayment and drip edge correctly, and then lay the IKO shingles or membrane per the manufacturer’s spec. Cleanup happens the same day. No nail piles left in the yard, no shingle wrappers blowing into the neighbor’s yard.
5. 5
   Test and verify. Before we call the job done, we water-test the repair if the roof allows it. We check the nailing pattern, the seal strips, the flashing laps, and the decking from inside the attic if accessible. A good roof shouldn’t need to be talked about, it should just hold. We verify it holds.
6. 6
   Your written guarantee. Every IKO job comes with the 365-Day Done Right Promise, in writing, for one full year. If the repair or installation fails within that year, we come back at no charge. That’s what we guarantee, and it’s what Garrison Partners has required since 2000.
