Reflectix Insulation in San Francisco, CA | Alden Attic Insulation
We provide independent Reflectix insulation service across San Francisco, and the single factor that separates good radiant barrier work from wasted money here is the fog. Reflectix foil only performs when it’s installed with a proper air gap and dry assembly, and San Francisco’s marine layer turns that detail into a requirement, not a suggestion. Our crews have pulled failed foil out of enough Sunset District and Richmond District attics to know exactly what happens when it’s stapled tight to sheathing. Call (254) 272-5876 for an assessment that tells you whether your attic actually needs Reflectix, and if it does, how we’ll install it so it works.
Why San Francisco Residents Choose Us for Reflectix Service
We’re an independent Reflectix service provider, not a manufacturer affiliate or authorized dealer, which means we recommend the right Reflectix product for your attic rather than whatever we’re incentivized to push. Bryce Holloway, our owner, grew up in Reseda where summer heat through a thin ceiling is something you understand before you can explain it. He learned the thermal performance side at Los Angeles Valley College’s construction technology program, then spent two-plus decades doing the work across California rooftops. In San Francisco specifically, we’ve handled Reflectix radiant barrier and foil products across the city’s older housing stock long enough to know how fog-belt attics stress these materials. That experience shapes every job we quote.
We install and service the full Reflectix line: Double Reflective Insulation Roll, Reflective Foil Insulation Roll, Radiant Barrier Roof Decking Foil, and Duct Insulation Wrap. We stock current manufacturer rolls locally for fast San Francisco turnaround, and we use foil-compatible tape and fasteners, never generic duct tape. If your attic needs work, you’ll get a written price before anything starts. If it doesn’t, we’ll tell you that too. For more on our Reflectix capabilities, see our Reflectix sales & service page.
Common Reflectix Insulation Problems We Solve in San Francisco
- Foil delamination and bubbling. San Francisco’s marine-layer humidity works its way into attic cavities, and Reflectix foil adhesive degrades over repeated summer fog and winter damp cycles. We see sheets where the foil surface has lifted in patches, killing the radiant reflection and leaving a surface that traps condensation instead of shedding it.
- Crushed bubble core. The Reflectix Double Reflective roll has a bubble-pack core that collapses when it’s compressed. We find this in San Francisco attics where someone walked on the foil during later HVAC or electrical work, or installed it too tightly between rafters. A crushed core means no air gap, and no air gap means no radiant performance.
- Foil stapled directly to roof sheathing. This is the most common Reflectix mistake we see in San Francisco, and it’s the most damaging. Without a vented air gap between the foil and the decking, the radiant barrier can’t do its job, and in a fog-belt attic it actively traps moisture against the framing. We’ve replaced decks with early rot from exactly this.
- Duct wrap peeling at joints. Reflectix Duct Insulation Wrap is only as good as its seams. When foil tape fails, joints peel open and conditioned air leaks into the attic. In San Francisco’s cool, damp attics, that also creates condensation points that drip onto ceilings below.
- Perforated foil used where non-perforated belongs, or vice versa. The perforation pattern exists for moisture passage. In a San Francisco roof deck application, using non-perforated Reflectix where humidity needs to move through can trap water against sheathing. We check which product is actually up there.
Reflectix Service in San Francisco: What Local Conditions Mean for Your Equipment
San Francisco’s summer fog and cool marine air create a reverse moisture drive in many attics. Most of the country worries about warm attic air condensing on cold surfaces in winter. Here, the problem runs the other direction: cool, damp outside air moves into the attic and meets warmer interior surfaces, so moisture condenses on framing and on any foil that’s tight against it. Reflectix foil installed directly on roof sheathing without a vented air gap becomes a condensation trap, and we’ve pulled delaminated sheets from attics in the Sunset District where rafters were already stained and the deck was softening. That’s why we treat radiant barrier and ventilation as one job in San Francisco, never two. The foil is only half the assembly; the air gap and vented path behind it are what make it work. Good insulation doesn’t announce itself, you just stop noticing the heat.
Reflectix Models & Products We Service in San Francisco
We install and replace Reflectix Double Reflective Insulation Roll in both 16-inch and 24-inch widths, the single-layer Reflective Foil Insulation Roll in perforated and non-perforated versions, the Radiant Barrier Roof Decking Foil, and Duct Insulation Wrap. We stock current Reflectix rolls for fast turnaround in San Francisco, and we carry foil-compatible tape and staples so joints actually hold and moisture doesn’t creep through. When existing foil is delaminated, crushed, or installed with no air gap, straight replacement with a correctly detailed radiant barrier usually makes more sense than spot repair. Patching failed foil over failed assembly just delays the same problem. This city’s service area spans every neighborhood; see San Francisco service area for coverage details.
Reflectix Service Pricing in San Francisco
Most Reflectix attic radiant barrier work in San Francisco runs $850 to $2,400 depending on attic square footage, whether existing foil needs removal, and what ventilation changes are required. Removal of failed or delaminated foil adds labor. So does correcting a roof deck install that needs furring strips to create the air gap. The lower end covers a straight forward foil replacement in a smaller attic with proper ventilation already in place. The upper end reflects full removal plus perforated foil on furring strips plus added baffles or roof venting. Every quote is a written price before work starts.

FAQs – Reflectix Insulation in San Francisco
Yes, but only when it’s installed with a vented air gap and the right perforation for the application. In San Francisco’s fog-belt attics, foil stapled tight to sheathing traps condensation and fails. Perforated Reflectix on furring strips with proper venting keeps the deck dry and the radiant barrier functional. Call (254) 272-5876 to have your attic assessed before buying material.
No. Reflectix works as a radiant barrier facing an air space, not as a cover sheet over existing insulation. Laying foil over Blown In Insulation in San Francisco does nothing useful and can trap moisture in the material below. We remove or properly retop existing insulation before any Reflectix install.
Perforated Reflectix Radiant Barrier Roof Decking Foil, installed on furring strips to hold a vented air gap. The perforations let moisture pass through so fog-driven condensation doesn’t sit against the sheathing. Non-perforated foil in this spot traps water against the deck and causes rot.
Look for bubbling or lifting foil, flattened bubble core, stained rafters, or dripping condensation. Any of those means the radiant barrier isn’t working and may be making the attic worse. We inspect San Francisco Attic Insulation setups and tell you plainly whether repair or replacement is the honest answer.
Yes. We won’t install Reflectix in San Francisco without addressing the air gap and vented path behind it. That includes baffles, roof or gable venting, and furring strips where the existing assembly lacks them. The foil and the ventilation are one job here; call (254) 272-5876 for an estimate that covers both.
