IKO Roofing: The San Francisco Owner’s Guide
We stock and install IKO-compatible roofing materials for San Francisco homes, with most repair jobs running between $470 and $2,125 and full replacements typically landing in the $9,440 to $23,600 range. Most owners discover a failing IKO roof the hard way: a water stain on the ceiling after a Pacific storm, granules collecting in the gutter, or a shingle that lets go somewhere above the bay window. The good news is that IKO makes identifiable product lines with clear markings, so matching your existing roof usually takes one look from the ground or a quick trip up the ladder.
IKO’s primary architectural lines in San Francisco are the Cambridge and Dynasty series, both of which have held up in our coastal fog and salt-air conditions. We also work on homes with older Marathon or Aristocrat three-tab shingles, which are thinner and more prone to wind lift on exposed hillside lots. Independent and not affiliated with IKO, Elmstead Remodeling San Francisco sources genuine IKO materials and quality aftermarket flashing, underlayment, and ventilation components that fit IKO specifications without compromise.
Which IKO Models This Applies To
If you can reach a bundle wrapper or check your original contract, look for the series name printed on the package or the shingle’s nail line. Cambridge shingles carry a wider exposure and a dimensional profile; Dynasty is IKO’s heavier architectural line with a reinforced nailing strip that matters in San Francisco’s wind corridors like the Outer Sunset and Twin Peaks. The older Marathon line has a flat, single-layer profile and a shorter expected lifespan than either architectural series.
The compatibility gotcha with IKO in San Francisco is the underlayment and ventilation pairing, not just the shingle itself. IKO’s own StormShield or a comparable high-temp synthetic underlayment should be used on low-slope sections common to Marina and Richmond District rooflines, and IKO’s warranty clock starts counting from the installation date, not the purchase date. We stock genuine IKO Cambridge and Dynasty shingles, IKO Hip & Ridge caps, and the full range of IKO roof-to-wall and step flashing profiles, so a repair rarely means waiting on a special order from a distributor in Hayward or San Jose.
Styles & brands we work with
Signs Your IKO Roofing Is Failing
- Granules in the gutters, especially after rain. IKO shingles shed surface granules as the asphalt core begins to oxidize. A heavy accumulation in one downspout points to a specific slope losing its UV armor, not just normal aging.
- Cupping or curling at shingle corners. This is usually an attic ventilation issue, and San Francisco homes built before 1970 often lack ridge and soffit vents. Moisture trapped under the IKO shingles degrades the adhesive strip and allows wind lift.
- Lifted or missing shingles after winter storms. The Dynasty line resists this better than Marathon, but any shingle where the sealant strip has failed becomes a sail in a 40-mph gust off the Pacific.
- Dark streaks or moss on north-facing slopes. Homes in the Sunset, Parkside, and Glen Park get minimal sun on certain roof planes. Moss roots can pry up IKO shingle tabs and create channels for water.
- Damp spots or staining on the underside of the roof deck in the attic. By the time this shows up, water has already made it past the shingles and the underlayment. The repair is no longer a shingle swap; it’s deck repair plus shingle replacement.

AfterReplacement Cost & What’s Included
In San Francisco, IKO roof repair work runs from $470 for a small shingle patch or flashing fix to $2,125 for a larger section replacement with new underlayment. A full IKO replacement lands between $9,440 and $23,600, driven by roof size, pitch, the number of existing layers we have to tear off, and whether the deck itself needs attention. Steeper roofs in Noe Valley and Diamond Heights take longer and cost more because of staging and safety requirements.
Every written price we give includes the IKO shingles, underlayment, ridge caps, flashing, fasteners, tear-off and disposal of old material, and the crew’s clean-up. What you see on the written estimate is what you pay, and there is no separate charge for shoe covers or drop cloths. We pull permits where San Francisco requires them, and every IKO repair or replacement we complete is covered by our 365-Day Done Right Promise: if it is not done right, we make it right.
DIY or Call Us?
If you’re comfortable on a ladder and just want to confirm what you’re looking at, check the shingle surface for granule loss, look for visible nail heads backing out, and take photos of any lifted tabs. That information helps us give you an accurate phone estimate. What we do not recommend is walking a steep San Francisco roof, especially after rain, to attempt a patch. Roofing work means working at height on surfaces that can be slick, and IKO’s warranty does not cover repairs made with mismatched materials or incorrect fastening.
If you have a leak, a section of lifted shingles, or granule loss on a large area, call us at (831) 480-4497. Graham Stein and the crew will name the exact IKO material your roof needs, write out the full price, and tell you what the repair day will look like before anything gets scheduled. There’s no charge for the estimate.
FAQs
IKO Cambridge and Dynasty shingles typically last 25 to 30 years in San Francisco’s climate, though fog-heavy zones like the Outer Richmond and Sunset can shorten that to 20 to 25 years because constant moisture slows the shingles’ ability to dry out. Regular inspection and keeping north-facing slopes clear of moss extends the lifespan. Call (831) 480-4497 if you want us to take a look at how your specific roof is aging.
Yes, a repair is the right call when the damage is limited to a few shingles, a flashing seam, or one section of underlayment. We repair what is actually failing and tell you honestly when a patch would just become another leak elsewhere. Call (831) 480-4497 and we’ll inspect the roof before recommending any work.
A small IKO shingle repair takes a few hours on site; a full replacement on an average San Francisco home runs three to five working days depending on roof size, pitch, and the tear-off. We set quiet hours so the crew isn’t running a roofing nailer first thing in the morning if the family’s asleep. Call (831) 480-4497 and we’ll give you an accurate timeline for your roof.
We stock IKO Cambridge and Dynasty shingles, matching hip and ridge caps, flashing, and synthetic underlayment in our San Francisco service vehicles, so most repairs can be completed the same day we diagnose the problem. Color availability depends on your roof’s specific IKO shade, but we can match most common colors from local supply. Call (831) 480-4497 to check availability for your home’s shingle color.
Tell me what the room needs to do, and we’ll figure out the rest from there. For your roof, the same idea applies: tell us what you are seeing, and we’ll name the fix and its price before any work begins. We also stock materials for KraftMaid cabinetry, Cambria countertops, and Silestone surfaces for the interior work many San Francisco homeowners pair with a roofing project. Call (831) 480-4497 for a free estimate.
