Windows
Alpha Windows feature precision manufacturing and energy-efficient designs that reduce heating and cooling costs. Our trained professionals ensure perfect installation with options including awning, basement, bay, and double-hung windows. Each unit comes with a lifetime limited warranty covering materials, workmanship, and performance.
Siding
Alpha Tri-Lock Vinyl Siding offers 24 colors and six styles with exclusive interlocking technology that prevents bulging seams. Installation options include clapboard, Dutch lap, and shake shingles that enhance curb appeal while providing durable protection against New York weather conditions.
Roofing
Our roofing systems use micro-weave technology for 50% greater durability than standard shingles. Backed by 30-year warranties with transferable coverage, these Class A fire-rated shingles from GAF, Owens Corning, and IKO provide superior protection against extreme weather conditions.
Patio Doors
Alpha Sliding Glass Doors feature reinforced frames, double-insulated tempered glass, and moisture-absorbing desiccants for year-round energy efficiency. The multi-point locking system ensures security while the patented hardware finish maintains aesthetic appeal over time.
