Your attic hits 140°F.
Your power bill hits $400.
Radiant barriers reflect 97% of the sun's heat back out of your attic — before it gets into your ceilings, your walls, and your wallet. We install them. You stop sweating the bill.
Your AC isn't broken. Your attic is the leak.
Most Alabama homes lose the cooling fight before it even starts. Sun hits the roof, the attic heats up like an oven, and that heat pours down through your insulation into every room below. Your AC runs all day trying to undo it.
The sun hits your roof at 160°F+
In July, an Alabama roof surface can top 160°F. That radiant heat pours straight through shingles and decking into your attic.
Your attic becomes an oven
Most Alabama attics sit between 130 and 150°F on summer afternoons — hotter than the surface of your cooktop.
That heat radiates into your living space
Traditional insulation slows conduction, but does almost nothing to stop radiant heat. Your ceilings warm, your AC never catches up.
You pay for it on every power bill
The average Alabama home can spend nearly $1,800/yr on cooling. A radiant barrier can cut that nearly in half.
One afternoon. One install. Lower bills all summer.
We handle everything. You don't climb a ladder, you don't pick materials, you don't deal with contractors. We show up, we install, we clean up.

Three summers in Alabama. Hundreds of attics.
We're a small Alabama company. We're not here to sell you on a miracle — we're here to staple foil to your rafters and save you money. These folks let us do exactly that.
"Our upstairs bedrooms were HOT in July. After SunDay Energy came out, we dropped 8 degrees upstairs and cut our August bill by $147."
"I was nervous about anyone going in my attic. Their crew was in and out in a half‑day. Clean as they found it. Bill's down, no complaints."
"The free inspection actually was free. No sales pitch. Got a number in writing, slept on it, called them back. Best home decision I've made in years."
Questions every homeowner asks.
Will this damage my roof or void my warranty?
No. We staple the barrier to the underside of your rafters — we never penetrate your roof deck or shingles. Your manufacturer's roof warranty stays fully intact, and we'll put that in writing.
How long does it last?
Aluminum doesn't degrade, rust, or lose reflectivity. Once installed correctly, your radiant barrier will outlast your roof. No maintenance, no replacement.
Will it cause moisture or mold problems?
No — and this is why we only use perforated aluminum. The tiny perforations let moisture vapor pass through, so nothing gets trapped against your decking.
How much does it cost?
Depends on attic size and accessibility, but every job starts with a free on‑site measurement and a firm written quote. Most Alabama homes pay for the install in 18–36 months of cooling savings.
How long does the install take?
A typical Alabama home is done in 4–6 hours, start to finish. We show up in the morning, we're gone by afternoon, and you don't lift a finger.
Do you only work in Alabama?
For now, yes. We're Alabama‑owned and we only serve Alabama homes. We know these summers, and we know these houses.
