Why Morgan Hill Residents Choose Us for Reflectix Service
We’ve worked on Reflectix foil systems from the older homes near Oakwood Avenue up through the newer builds off East Main and throughout the Cochrane master-planned community. Wes Okafor, our owner and lead technician, learned the trade at Olive-Harvey College in Chicago, where he ran blower-door equipment before he ever handled a bag of blown-in cellulose. That background shows up in how we approach every Morgan Hill job: we measure first, seal second, insulate third.
Our crew carries Reflectix sales & service capability across the full product line, but we don’t pretend the foil does more than it can. When a homeowner calls us about Reflectix, we start with a written scope and a blower-door baseline if the job warrants it. We publish before-and-after numbers on applicable jobs so you can verify the result yourself. No authorization from Reflectix Inc. means no corporate script, no warranty runaround, and no pressure to use a product that doesn’t fit your assembly.
We’ve logged jobs in Morgan Hill neighborhoods where the afternoon wind through Coyote Valley hits attic venting hard enough to whistle through unsealed baffles. That local knowledge changes how we install Reflectix here versus how a San Jose crew might handle the same product sheet.
Common Reflectix Insulation Problems We Solve in Morgan Hill

- Foil delamination from dust abrasion and thermal cycling. Morgan Hill’s wind corridor pulls fine dust through attic vents year-round. That dust abrades the reflective surface on Reflectix rolls over time, and the valley’s wide temperature swings, summer highs in the low-to-mid 90s°F dropping to winter overnight lows in the 30s°F, accelerate the peeling. We see this most in homes off Dunne Avenue and East Main where the attic venting faces the prevailing wind.
- Compression and gap failure in cathedral ceilings. The 1990s tract homes throughout Coyote Creek and South Morgan Hill were built with two-by-six rafters, leaving only an R-19 cavity and no room for a ventilation baffle. Reflectix stapled flat against the batt eliminates the required air space; the radiant barrier becomes a conductive heat path instead of a reflective one. We remove these failed assemblies regularly.
- Moisture trapping at the foil underside. Wind-driven rain through unsealed penetrations is a real factor in the Coyote Valley gap. Reflectix installed without proper drying paths traps that moisture against the roof deck. We’ve found staining and early sheathing decay in homes where the foil was treated as a vapor barrier rather than a radiant barrier.
- Reflectix used as standalone insulation in underperforming assemblies. Minimum-code batt from the 1985-2005 buildout doesn’t meet current Title 24 requirements for CEC Climate Zone 4. Homeowners sometimes add Reflectix expecting it to compensate for R-19 rafter cavities. It won’t. We tell you when a dense-pack or spray foam retrofit is the better spend.
- Wind-torn seams and ridge gaps. The afternoon wind funneling between the Diablo Range and Santa Cruz Mountains pulls at poorly taped Reflectix seams. Standard household tape fails in months. We use Reflectix-brand foil tape or equivalent ASTM-rated seam seal, and we anchor at structural points where the wind load concentrates.
Reflectix Service in Morgan Hill: What Local Conditions Mean for Your Equipment
Morgan Hill sits at the southern throat of Coyote Valley, where afternoon winds funnel aggressively through the gap between the Diablo Range and Santa Cruz Mountains. This microclimatic wind corridor is measurably stronger than in neighboring Gilroy or San Jose. For Reflectix radiant barrier installations, that wind load isn’t abstract; it’s the primary reason foil-only retrofits underperform here.
We were called to a 1994-built home in the Cochrane master-planned community where the homeowner had Reflectix foil stapled over R-19 batt in a cathedral ceiling and still saw summer attic temps over 140°F. Our crew found the foil compressed against the batt with no air space and wind-driven gaps at the ridge, so we removed the failed assembly, air-sealed the top plates and baffles, and reinstalled Reflectix roof deck radiant barrier with proper standoff and foil tape. The homeowner reported an immediate drop in upstairs cooling load. Without that air sealing at the roof deck and baffle edges, the Coyote Valley wind simply bypasses the foil layer and negates its radiant performance. Seal the leaks first. The insulation just holds what you’ve already captured.
This pattern, local contractors encounter it repeatedly, simply doesn’t apply to the flatter, more sheltered Bay Area markets to the north. A crew working in Campbell or Alum Rock doesn’t face the same infiltration-driven failure modes. That’s why our Morgan Hill service area crews carry extra foil tape, additional baffle stock, and blower-door equipment standard on Reflectix jobs.
Reflectix Models & Products We Service in Morgan Hill

We work with the full Reflectix radiant barrier line: Double Reflective Insulation Roll (R-21 for 5/16-inch thickness), Reflective Foil Insulation with double-sided reflective surface, Radiant Barrier Roof Deck and Attic products for foil-facing applications, and Reflective Foil Tape for sealing seams between rolls. Our Morgan Hill crew stocks Double Reflective Roll and foil tape on the truck for same-day repairs.
We primarily use Reflectix-brand radiant barrier rolls and their matching foil tape for repairs. When full replacement is needed, we’ll substitute equivalent ASTM-rated radiant barrier products if Reflectix is unavailable or the application calls for a different form factor. We’re not locked into any single brand. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber as the job requires.
Our honest stance: Reflectix works well as part of a system with proper air sealing and R-value, but it is not a substitute for adequate bulk insulation. We’ll tell you if a top-up or our Spray Foam Insulation in Morgan Hill is the better spend.
Reflectix Service Pricing in Morgan Hill
Most Reflectix radiant barrier jobs in Morgan Hill run between $1,800 and $3,400 for attic applications, depending on square footage, accessibility, and whether we’re retrofitting over existing insulation or removing a failed assembly first. Cathedral ceiling retrofits, common in the 1990s South Morgan Hill builds, typically land at the higher end due to the confined cavity work and baffle installation.
Every estimate includes a written scope, a flat price, and a documented photo record. We don’t start work without a written price in hand, Haven Standard Clause 1.

FAQs - Reflectix Insulation in Morgan Hill
Reflectix qualifies as a radiant barrier in CZ4, but it does not replace bulk insulation. The California Energy Commission’s Title 24 requirements for Climate Zone 4 call for specific R-values in attic assemblies, radiant barrier or not. We assess your current R-value and air leakage before recommending any Reflectix work. Call (669) 280-8103 for a written assessment.
Your two-by-six rafters likely left only an R-19 cavity with no ventilation baffle room, and the Reflectix was probably stapled flat against the batt with no air space. The Coyote Valley wind then pulled gaps at the ridge. We remove these failed assemblies, air-seal, install baffles, and reinstall with proper standoff. Most cathedral ceiling retrofits run $2,600-$3,400.
Often yes, if the existing insulation is dry, uncompressed, and the attic floor is air-sealed first. We won’t lay Reflectix over an unsealed our Attic Insulation in Morgan Hill floor. That’s expensive decoration. We air-seal top plates, can lights, and penetrations, then install the radiant barrier with proper standoff. Call for a site-specific written scope.
We use Reflectix-brand foil tape or equivalent ASTM-rated seam seal on all overlaps, with mechanical anchoring at structural points where wind load concentrates. Standard tape fails in months here. We also air-seal the perimeter so wind isn’t pushing through gaps behind the foil.
Reflectix can work in crawl spaces for radiant heat control, but it’s rarely the right first move in Morgan Hill’s older homes. Ground moisture and the valley’s temperature swings mean vapor management and air sealing usually take priority. We’ll inspect your crawl space and give you a written recommendation, not a product push. Call (669) 280-8103 for a free estimate.
