Aluminum Soffit That Protects and Ventilates

Soffit is the paneling on the underside of your roof overhang. It closes off the eaves from birds, insects and weather, and vented soffit lets fresh air into the attic so heat and moisture can escape through your roof vents.

We stock Gentek Hi-Tensile aluminum soffit because aluminum simply lasts. It won’t rot, split or warp from moisture, and the baked-on finish won’t blister, flake or peel. It’s the choice for contractors who don’t want callbacks and homeowners who never want to repaint an eave again.

Our vented soffit comes in the same colors as our 6″ aluminum fascia, so rooflines match from end to end.

Why Aluminum Soffit Is the Smart Choice

Healthy attic airflow

Vented soffit is the intake half of your attic ventilation. It helps prevent summer heat buildup and winter moisture, frost and ice dams.

Moisture-proof

Aluminum can’t rot, swell or split, even where snowmelt and ice sit on the eaves every winter.

Lifetime warranty

Gentek backs its Hi-Tensile aluminum soffit and fascia with a lifetime limited, non-prorated, transferable warranty.

Keeps pests out

A closed-in eave keeps birds, wasps and rodents from nesting in the overhang.

Stiff T4 profile

The four-panel T4 design with V-grooves adds rigidity, so long runs stay flat and straight.

Matches everything

Gentek’s coordinated colors match its fascia, trim and vinyl siding across the product line.

Frequently Asked Questions

Should I use vented or solid soffit?

Use vented soffit on eaves over a ventilated attic. It’s the air intake that works with ridge or roof vents. Use solid soffit where there’s no attic behind it, like porch ceilings, gable-end overhangs and covered patios. Many homes use both.

How much soffit venting does my attic need?

The building code generally calls for 1 square foot of net free vent area for every 150 square feet of attic floor (or 1:300 in some cases), split between intake (soffit) and exhaust (ridge or roof vents). Gentek’s 12″ T4 center-vented soffit gives 3.9 square inches per lineal foot. Fully vented soffit (11.6 sq in per foot, special order) is an option when you need more intake. Check with your local building department or installer for your specific home.

Is aluminum or vinyl soffit better?

Both are low-maintenance. Aluminum is stiffer, so it sags less on wide overhangs. It’s non-combustible, and its baked-on finish holds color well in strong sun. That’s why we focus on aluminum soffit.

What does T4 soffit mean?

T4 describes the profile: each 12″ panel is formed with four smaller panel sections, which gives it a clean, grooved look and extra rigidity.

Do you have aluminum soffit in stock in Twin Falls?

Yes. We stock Gentek 12″ T4 aluminum soffit (center-vented in 18 colors, solid in White, Black, Bronze and Musket Brown), plus J-channel and fasteners, at 299 Addison Ave W, Suite B. Call 208-539-0851 to confirm your color.

Can I match soffit to my fascia and siding?

Yes. Our center-vented soffit and 6″ fascia come in the same 18 colors, and Gentek’s Color Clear Through® system coordinates them with its siding and trim.
