Reflectix Insulation in San Bernardino, CA | Laguna Hills Insulation
We install and repair Reflectix radiant barriers across San Bernardino, and the short version is this: in this inland heat, Reflectix works only as well as the attic ventilation around it. Most San Bernardino homes we see have the product but not the airflow, and that’s the gap we close. As an independent contractor, we’re not tied to Reflectix corporate, and we’re not a one-brand shop either.

Why San Bernardino Residents Choose Us for Reflectix Service
We’ve pulled apart and reinstalled enough Reflectix in Highland and San Bernardino attics to know exactly how the product behaves when a July roof deck hits 140°F and stays there. Foil delamination, staple pull-through, dust-caked surfaces that stop reflecting, these are predictable failures in this climate, and we can diagnose them in about fifteen minutes. Garrett Lund, our owner, has spent over two decades installing and troubleshooting insulation in Southern California attics. He got his grounding in building science at Saddleback College’s construction technology program, and he’ll tell you straight: a radiant barrier without a proper air gap is just expensive wallpaper. One of the things Garrett repeats on job sites is that the right material in the right place does the work. Everything else is just sales pitch. That’s the standard we bring to every San Bernardino attic we enter.
Our approach to Reflectix work in San Bernardino is independent. We don’t get kickbacks from the manufacturer, and we don’t have a quota to hit on a particular foil roll. If your existing Reflectix is worth saving, we’ll tell you. If it’s shot, we’ll show you the delamination with a flashlight and explain why patching it won’t restore reflectivity. We carry genuine Reflectix product for section replacements and keep aftermarket radiant-gap spacers and butyl flashing tape on the truck for retrofits. That means most San Bernardino service calls get completed same day without waiting on a supplier.
If you’re comparing bids across insulation contractors, you’ll probably notice we stock more material options than a single-line shop. That’s by design. We work with eight manufacturers, Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, because sometimes the right fix for a San Bernardino attic isn’t more foil. Sometimes it’s Rockwool at the top plates or an air-sealing pass. We’ll tell you which product actually fits, even when it’s not the most expensive one on the quote.

Common Reflectix Insulation Problems We Solve in San Bernardino
- Foil delamination and bubbling from sustained attic heat. In San Bernardino’s older ranch-style attics, especially in the 1950s-to-1970s tracts on the flat valley floor, roof decks regularly exceed 140°F in summer. Reflectix foil that was stapled tight to OSB or installed without a radiant gap starts to bubble and peel. Once the foil separates from the bubble-pack core, its reflectance drops sharply. We remove the failed sections, address the ventilation gap that caused the failure, and install new Reflectix Double Reflective Roll with proper spacing.
- Dust and soot accumulation killing reflectivity. The inland valley’s dry, windy springs push fine dust into San Bernardino attics through every eave gap and gable vent. A reflective surface only works when it’s clean and shiny. After a few seasons, dust turns the foil dull gray, and emissivity climbs, meaning the barrier starts absorbing heat instead of rejecting it. We inspect reflective surfaces during every San Bernardino service call and will tell you honestly whether cleaning restores performance or replacement makes more sense.
- Moisture trapping against roof sheathing. When Reflectix is installed tight against the underside of a low-pitch San Bernardino roof deck without ventilation channels, condensation forms between the foil and the wood on cold winter nights. We see corrosion stains and deck damage on the foil side in homes where someone treated a radiant barrier like a substitute for proper roof venting. The fix is always the same: create the air path first, then reinstall the barrier.
- Rodent and bird damage in low-pitch attics. San Bernardino’s older central and west-side bungalows have accessible low-pitch attics that rats, mice, and nesting birds find easy to enter. Reflective foil gets torn, chewed, and soiled. We find nests pressed against barriers regularly. After repairing the damage, we can discuss exclusion and vent screening if you’re seeing a repeat problem, because no insulation product holds up to persistent animals.
- Staple pull-through during Santa Ana wind events. Older San Bernardino homes often have 3/8-inch roof sheathing, which doesn’t hold staples well under wind-driven pressure changes. During Santa Ana events, attic pressures fluctuate, and the staples holding the foil to the deck slowly work loose. The barrier sags, loses its air gap, and starts resting against the framing. We replace pulled-through sections with a fastening pattern that distributes the load better and resists the cycling you get here.
Reflectix Service in San Bernardino: What Local Conditions Mean for Your Equipment
Here’s the thing most generic Reflectix pages won’t tell you: this product degrades differently in San Bernardino than it does twenty miles west. The older central and west-side San Bernardino neighborhoods, think the tract homes off Baseline and the craftsman bungalows toward the 215, sit on flat valley floor with minimal tree canopy and relentless solar exposure. The attics in these homes spike past 140°F in July, and many of the 1950s-to-1970s low-pitch roofs were framed with barely any roof-deck ventilation to begin with. Reflectix installed in those conditions cycles through more extreme thermal expansion and contraction in a single summer than coastal LA or Orange County attics see in five years. Foil that would hold up for decades in a mild marine layer atmosphere delaminates here in a few seasons. Dust compounds the problem. The dry spring winds push silt through eave gaps, and that dust settles on the reflective face, turning a material designed to bounce radiant heat into a passive heat absorber. We don’t quote a Reflectix repair in San Bernardino without looking at the vent situation first, because installing fresh foil into an unvented attic is just scheduling the next failure. That’s why our standard practice for San Bernardino service area homes is to pair any Reflectix install with baffle and vent upgrades. The barrier handles the radiant load; the airflow handles the heat the barrier doesn’t catch.
We worked a 1962 ranch home just west of downtown San Bernardino last summer where the original Reflectix foil stapled to the roof deck had delaminated across two full bays. Wind-blown dust had caked the remaining foil to a dull charcoal. The attic was sitting at 147°F on a 104°F afternoon. Our crew removed the failed sections, installed new Reflectix radiant barrier with a proper air gap, added baffles at the eaves to restore cross-ventilation, and air-sealed the top plates. The homeowner called back the next week to say the upstairs rooms dropped several degrees and the AC had stopped short-cycling by mid-afternoon — the kind of result we aim for with every Reflectix repair in Loma Linda and throughout the county. That’s the difference between a foil replacement and an attic repair that understands San Bernardino conditions.
Reflectix Models & Products We Service in San Bernardino
We service the full Reflectix line in San Bernardino attics. That includes the Double Reflective Insulation Roll with the bubble-pack core, the single-sided Reflective Foil Roll, the perforated R-21 Attic Floor Insulation, and the foil-faced Radiant Barrier Roof Decking product. When a section has failed and we’re replacing it, we use genuine Reflectix rolls and foil tape so the new material matches the original performance specs. For retrofit work, we pair the reflector with aftermarket radiant-gap spacers and quality butyl flashing tape, because the air gap is what makes the product work. If a barrier is more than 50 percent delaminated or dust-fouled, we’ll recommend full replacement over spot repair. Patching compromised foil rarely restores reflectivity, and we’d rather tell you that upfront than sell you a repair that won’t perform. San Bernardino heat exposes partial fixes within a season.
Reflectix Service Pricing in San Bernardino
Reflectix service costs in San Bernardino vary by the size of the attic, the pitch, the condition of what’s already up there, and whether ventilation work is needed alongside the foil. A straightforward section replacement on a small ranch attic runs less than a full removal-and-reinstall with new baffles and air sealing on a larger home. The material itself is not the dominant cost; labor and the condition of the attic framing drive most of the quote. What we don’t do is give you a price over the phone without seeing the space. Every San Bernardino estimate we provide is free, and it includes a full attic inspection so you’re not paying to guess. If you want a real number for your home, call (866) 393-6041 and we’ll schedule a walkthrough.

FAQs – Reflectix Insulation in San Bernardino
No, and we’d never install it that way. Reflectix radiant barrier works by reflecting heat before it reaches the insulation below, which means it needs an air gap on at least one side. Laying it directly on top of compressed fiberglass batts eliminates the gap and turns the product into a vapor-barrier blanket that can trap moisture. The right approach is to install the barrier at the roof deck with proper spacing or to address the attic floor insulation separately. If you’re unsure what your attic currently has, call (866) 393-6041 and we’ll inspect it.
Look for foil that is bubbling, peeling away from its core, sagging between staples, or coated in gray dust. Also check for dark staining on the deck side, which points to trapped moisture. If you can’t comfortably inspect the space, or if your upstairs rooms are hotter than the downstairs by late afternoon, the barrier may have lost its reflectivity. Call (866) 393-6041 for a diagnostic visit.
It does not. A radiant barrier reflects radiant heat, but it does not provide meaningful thermal resistance on its own. San Bernardino attics still need proper R-value from blown-in fiberglass, cellulose, or mineral wool at the attic floor. Reflectix is a complement to attic insulation, not a stand-in. We’ll help you get both layers right.
Indirectly, yes. A properly installed radiant barrier won’t stop embers from entering through vents, but sealing gaps and screening openings along the roofline reduces the pathways embers use. During Santa Ana events, wind-driven pressure can pull attic air through unsealed gaps. We address vent screening and top-plate air sealing during Reflectix installs so the attic is tighter overall. If you want a full ember-hardening assessment, call (866) 393-6041.
Most low-pitch San Bernardino roofs need both eave intake and ridge or gable exhaust to create cross-ventilation. A common target is one square foot of ventilation per 150 square feet of attic floor, split evenly between intake and exhaust, though low-slope roofs often need more. Reflectix performs only when air moves through the space above it. Call (866) 393-6041 and we’ll calculate your attic’s current vent ratio and tell you what it would take to get the airflow right.
