What Our Radiant Barrier Installation Service Includes
Radiant barrier installation isn’t one-size-fits-all. The right setup depends on your attic layout, roof pitch, existing insulation, and how your home handles the West Hollywood sun. Here’s what we do, broken down by the specific types of radiant barrier work we handle.
Attic Radiant Barrier
An attic radiant barrier is a reflective material installed on the underside of your roof rafters or across the attic floor joists. Its job is simple: bounce radiant heat back out before it can soak into your insulation and ceiling drywall. In West Hollywood, where summer temperatures routinely push past 90 degrees with direct sun on tile and asphalt roofs, attic temps can hit 140 degrees or more without a barrier. We install the barrier to face the right air gap, which is what actually makes it work. A radiant barrier pressed flat against a surface does almost nothing. We staple it to rafter bottoms or lay it over existing insulation with the reflective side up, and we always check that your attic ventilation is working alongside it.
Radiant Barrier Foil
Radiant barrier foil is the most common material we use in West Hollywood attics. It’s a double-sided or single-sided reinforced aluminum foil, and it reflects up to 97% of radiant heat when installed with an air gap. We carry heavy-duty foil that won’t tear when it’s being stapled, which matters because cheap foil turns into a mess halfway through installation. For older West Hollywood homes with low attics and tight rafter spacing, foil is often the only viable option. Our techs cut it precisely around vents, recessed light housings, and framing so it performs without blocking airflow.
Radiant Barrier Roof Deck
Radiant barrier roof deck installation applies the reflective layer directly to the underside of the roof sheathing, before the roofing material goes on. This is a new-construction or re-roof method, and it’s the most effective placement because the barrier stops heat at the very first point of entry. If you’re re-roofing your West Hollywood home anyway, adding a roof deck radiant barrier costs a fraction of what it would to retrofit later. We coordinate with your roofer’s schedule so the barrier goes down after the old roof is stripped and before the new decking or underlayment is installed. Our techs have done this on flat-roof moderns in the hills and pitched-roof Spanish styles in the flats.
Radiant Barrier & Ventilation
A radiant barrier only works as well as the attic ventilation behind it. If your attic has no ridge vent, no soffit vents, or blocked gable vents, the reflected heat has nowhere to go. That’s why every radiant barrier install from Walt’s Insulation includes a ventilation check. We look at your existing intake and exhaust, clear blocked soffits, and tell you honestly whether adding a solar attic fan or extra venting makes sense. We don’t upsell ventilation you don’t need. But in West Hollywood attics where we find zero airflow, we’ll tell you straight: the barrier alone won’t fix the heat problem.

Brands We Service for Radiant Barrier Installation
We work with radiant barrier materials from manufacturers we trust, including Owens Corning and Johns Manville. Owens Corning’s reflective barriers hold up beautifully in the dry West Hollywood climate, and we’ve installed enough of it to know exactly how it handles tight rafter bays and irregular framing. Johns Manville’s foil products are what we reach for on retrofit jobs where durability during installation matters most, because their reinforced facing doesn’t shred when it snags a nail.
We also stock GreenFiber products for jobs where a radiant barrier pairs with blown-in insulation. If your attic currently has old, settled insulation under the barrier, GreenFiber’s cellulose can be blown right over it, and we often recommend doing both at once since the labor overlap saves you money. Whether your home calls for Owens Corning, Johns Manville, GreenFiber, or another make entirely, we can help. The material matters, but the installation details matter more, and that’s what we’re known for.
Signs You Need Radiant Barrier Installation Right Now
- Your upstairs is 8 to 12 degrees hotter than downstairs. This is the most common complaint we hear in West Hollywood homes, especially in two-story Spanish and Mediterranean styles built before the 1990s. Heat loads into the attic all day, then radiates down through the ceiling for hours after sunset. A radiant barrier cuts that heat at the source.
- Your AC runs constantly from June through October. If your air conditioner can’t cycle off during the hottest parts of the day, your attic is likely feeding it a steady stream of heat. Reducing attic temperature with a radiant barrier means less runtime, which means lower electric bills from LADWP and less wear on your compressor.
- Your attic is over 130 degrees when you check it. Go up there on a summer afternoon and you’ll feel it immediately. A properly installed radiant barrier should bring that number down 20 to 30 degrees. If you can barely stand in your attic for two minutes, that’s a sign your home is cooking from the top down.
- Rooms facing south or west never get comfortable. West Hollywood sun is relentless on south- and west-facing roof planes. Those roof sections heat up first and stay hot longest, and the rooms below them are the ones that struggle. A radiant barrier under those specific roof planes makes a noticeable difference within days of installation.
- You can feel heat radiating through the ceiling at night. Put your hand on the ceiling of an upstairs room around 9 or 10 p.m. If it’s warm to the touch hours after sundown, your attic has been storing heat all day and releasing it into your living space all night. That’s exactly the problem radiant barriers are built to solve in West Hollywood’s climate.
Our Radiant Barrier Installation Process - Step by Step
- 1
Attic inspection and measurement. We start by going into your attic, not just measuring from the hatch. Our techs check rafter spacing, existing insulation depth, ventilation, access points, and anything else that affects how the barrier should be installed. We also look for rodent activity, water stains, and wiring issues, because installing over those problems just traps them.
- 2
Straightforward quote with no pressure. After the inspection, we give you a written quote that spells out the barrier type, the square footage, the ventilation work (if any), and the total price. That’s the price you pay. No surprise add-ons. No “we found something else” calls halfway through the job. And if you have another written estimate, bring it in. We’ll give you a free second opinion on it.
- 3
Prep and safety. On install day, our background-checked, uniformed technicians arrive in a marked vehicle. They lay down protection for your floors and furniture path, set up safe access to the attic, and make sure recessed lights and wiring are handled correctly. We don’t bury can lights or junction boxes, because that’s how fires start.
- 4
Barrier installation and ventilation check. We install the radiant barrier according to the method we agreed on, whether that’s stapled to rafters, laid over existing insulation, or installed at the roof deck. Every staple line is straight, every seam overlaps correctly, and every vent stays clear. Then we check ventilation one more time to make sure the system will actually work.
- 5
Final walkthrough and Done Right Promise. Before we leave, we show you the finished install and answer any questions. You’ll have a real person walking you through what was done and why. And because every job is covered by our lifetime Done Right Promise, if anything isn’t done right, we come back and fix it. No runaround, no fine print, no expiration date.
How Much Does Radiant Barrier Installation Cost in West Hollywood?
A typical attic Radiant Barrier Installation costs $900 to $1,800 for a 1,000 to 1,500 square foot attic in West Hollywood. Radiant barrier foil on the attic floor over existing insulation lands on the lower end. Stapling foil to the rafters costs more because of the labor and ladder work involved. Roof deck radiant barrier during a re-roof adds $0.50 to $1.00 per square foot of roof area, depending on the roofing timeline. If we’re pairing a radiant barrier with blown-in insulation or a ventilation upgrade, a combined job typically runs $1,800 to $2,400 total.
What moves the price: attic accessibility (low attics with tight framing take longer), the size of the attic, whether we’re laying the barrier flat or stapling it overhead, and whether your ventilation needs correction. What shouldn’t move the price: vague “difficulty” fees, arbitrary upcharges, or sales pressure to add services you don’t need. We give upfront pricing before any work starts. And remember, if you have a written estimate from someone else, we’ll give you a free second opinion on it. No trip charge in our service county, either.

Frequently Asked Questions - Radiant Barrier Installation in West Hollywood
Radiant barrier installation is the process of placing a reflective material, usually reinforced aluminum foil, in your attic to reflect radiant heat away from your living space. In West Hollywood’s climate, the barrier is most often stapled to the underside of roof rafters or laid over existing attic insulation. The key is the air gap, which allows the reflective surface to actually bounce heat. Without that gap, the barrier conducts heat instead of reflecting it, and that’s a mistake we see from rushed installs all over the city.
Most West Hollywood radiant barrier jobs are done in a single day, usually 4 to 8 hours depending on attic size and access. A small attic with easy access can be finished in about half a day. A larger attic with tight rafter spacing, low clearance, or the need for ventilation work may take a full day or a day and a half. We’ll give you a clear time estimate before we start, and we stick to it.
Radiant barrier installation in West Hollywood costs between $900 and $2,400 for most homes, depending on the attic square footage, installation method, and whether additional ventilation work is needed. A simple foil-over-insulation job on a 1,000 square foot attic starts around $900, while a full rafter-stapled install with ventilation correction runs toward the higher end.
