Vinyl Siding That Works for Rockford Homes

We carry Sequoia Select vinyl siding, a top-performing product line built for durability and consistent installation. With a .046-inch panel thickness for horizontal profiles and .050-inch for vertical Board and Batten, this siding resists warping, cracking, and impact damage—even in extreme conditions.

It features a reinforced locking system and a full nailing hem, ensuring a tight, weather-resistant fit that holds up in Rockford’s changing climate. Whether you’re working on a ranch, two-story, or multi-unit property, this siding delivers dependable performance.

Woodgrain Look with a Strong, Weather-Resistant Build

Sequoia Select siding mimics the look of real wood with a cedargrain texture and soft matte finish. It adds the charm of painted wood without the upkeep, and the ¾-inch butt height enhances the home’s depth and shadow lines.

Thanks to its Advantage Lock system, the panels remain aligned and secure, even after repeated freeze-thaw cycles. Available profiles include Double 4 inch Clapboard, Double 5 inch Dutch Lap, and vertical Board and Batten, making it easy to match or refresh any style of home in Rockford.

Colors That Complement Rockford Architecture

Rockford’s homes range from early 20th-century builds to modern suburban styles. We offer a wide range of vinyl siding colors to suit every architectural type. Choose timeless shades like Almond, Wicker, and Pearl for a classic look or go bold with Iron Ore, Midnight Surf, or Storm for a more modern appearance.

All siding colors are backed by ChromaTrue fade protection to keep your home looking vibrant and clean, even with years of sun and weather exposure.

Add Insulated Siding for Comfort and Efficiency

Sequoia Select EnFusion is our insulated vinyl siding system, designed for energy savings and added protection. With a layer of bonded rigid foam insulation behind each panel, EnFusion siding helps reduce heating and cooling bills, block exterior noise, and increase impact resistance.

It’s a smart choice for Rockford homeowners looking to improve efficiency in older homes or boost long-term value in new construction projects.
