ECO Window Systems Roofing: The San Francisco Owner’s Guide
ECO Window Systems roofing components in San Francisco typically run $470 – $2,125 installed for repairs and $9,440 – $23,600 for full roof replacement, depending on the specific part and roof condition. We stock common ECO Window Systems-compatible flashing, sealants, and roof-to-window transition components on our trucks, and most replacement work is completed in a single visit. The call usually comes after a homeowner notices water staining on the ceiling near a skylight or roof window, or after a windy night leaves a piece of flashing dangling loose over a bedroom.
San Francisco’s fog, salt air from the bay, and steep roof pitches in neighborhoods like the Sunset District, Bernal Heights, and Noe Valley put real stress on every roofing component that touches a window or skylight. ECO Window Systems builds solid windows, but the roofing elements around them – flashing kits, underlayment transitions, and sealant beads – take the brunt of our weather. When those fail, water finds its way in, and that’s when we get the call.
Which ECO Window Systems Models This Applies To
The roofing components we service apply to ECO Window Systems skylights, roof windows, and the roof-to-wall transition kits used in their larger fixed units. The key compatibility point: ECO Window Systems uses a proprietary flashing profile with a raised stand-up seam, which means a generic big-box flashing kit won’t seat correctly. If the flashing was installed with the original window, the stamped part number on the aluminum lip will start with “ECO-WF” followed by four digits. Take a photo of that stamp before calling; it saves a trip.
For owners who don’t have the original paperwork, measure the outside frame width of the roof window. ECO’s residential line runs in three standard widths: 23-1/2″, 30-1/2″, and 44-1/2″. The flashing kits are width-specific, so that measurement tells us which kit to bring. On the OEM versus aftermarket question: we carry both. OEM ECO flashing costs more and matches the original profile exactly. The aftermarket kits we stock from a Sacramento supplier run about 30% less and have held up well in San Francisco conditions, but we always write the OEM option down so you can compare before committing.

Signs Your ECO Window Systems Roofing Is Failing
- Water staining on the ceiling near the window or skylight. This usually means the sealant bead between the flashing and the roof membrane has dried and cracked. San Francisco’s fog cycle keeps that joint damp for months at a time, which shortens sealant life more than most homeowners expect.
- Visible daylight through the frame edge from inside. The flashing has lifted or pulled away from the rough opening. Wind off the Pacific – especially on west-facing slopes in the Outer Sunset – can peel flashing over time if the original install used fewer fasteners than the roof pitch demands.
- Granules from the shingles collecting in the gutter below the window. This points to shingle breakdown at the transition point, not the window itself. When we see granule buildup concentrated in one spot, we know the roof line is shedding at the flashing seam.
- Draft or temperature change around the window frame. The insulation collar or the underlayment transition has shifted. It’s not always a water leak, but air movement through a roof window in a San Francisco summer fog bank means the seal isn’t doing its job.
- Banging or rattling from the window during high wind. The saddle flashing or the fastening clips have loosened. This is the one owners sometimes ignore because it only happens a few nights a year, but loose roofing hardware has a way of becoming a leak the following winter.

AfterReplacement Cost & What’s Included
For ECO Window Systems roofing work in San Francisco, small repairs – replacing a cracked flashing boot, re-beading sealant, reseating a loose clip – run $470 to $2,125. That includes the part, labor, and a written line item for everything we touch. Full roof replacement ranges from $9,440 to $23,600 depending on roof size, pitch, tear-off requirements, and whether the ECO windows need new flashing integrated into the new roof plane.
The biggest cost driver on repair work is roof access. A steep Noe Valley roof with no staging area costs more than a walkable Bernal Heights bungalow roof. We’ll tell you which side of that range you’re on before we pick up a ladder. Every job includes the written price before work starts, shoe covers and drop cloths inside the house if we need interior access, and a photo of the finished cleanup. The work is covered by our 365-Day Done Right Promise: if the repair doesn’t hold, we come back and make it right at no charge.

DIY or Call Us?
What you can safely do: take photos of the failing area from the ground or from inside the house, note where water stains appear after rain, and read us the part number from the flashing lip if you can reach it from a bedroom window. That’s useful and costs nothing. What we don’t recommend: pulling up flashing or re-sealing a roof joint yourself. A roof in San Francisco is never flat, the fog makes every surface slick, and a misplaced tool can turn a $470 reseal into a $2,100 repair and a busted pane.
This is one place where calling is faster than guessing. Graham Stein has worked on San Francisco roofs for years and writes out every cost before a single tool touches the floor. Tell me what the room needs to do, and we’ll figure out the rest from there.
FAQs
In San Francisco’s fog and salt air, the sealant and flashing around ECO Window Systems skylights and roof windows typically last 10 to 15 years before they need resealing or replacement. The windows themselves last longer, but the roofing transition is the weak point. Call (831) 480-4497 for an exact assessment of your roof.
Yes, in many cases. If the aluminum flashing itself is intact and the failure is sealant separation or a loose clip, we can re-bead and reseat it for $470 to $825. If the flashing is cracked or corroded through, replacement is the honest fix. Either way, the estimate is free.
Most flashing and sealant repairs take one visit, typically two to four hours including roof access and cleanup. Full roof replacements with ECO window integration take three to seven days depending on size and weather. We’ll give you a written schedule along with the written price.
We stock common ECO Window Systems-compatible flashing sizes and sealants on our trucks, and we can source OEM parts from regional suppliers within a few days when a specific width isn’t on hand. We also stock parts for KraftMaid, Cambria, and Silestone products for our kitchen and bath work, so one call covers most of what a San Francisco home needs.
