Skylight Replacement in Suffolk County, NY

Skylight replacement costs vary based on size, type, and roof complexity, typically ranging from $800 to $2,500 per skylight including installation. Velux skylights with professional installation usually cost 3-4 times the price of the unit alone, but this includes proper flashing, waterproofing, and our leak-free guarantee. We provide upfront pricing with no hidden fees, and financing options are available for qualified homeowners.

Most skylight leaks happen because of improper flashing installation or degraded sealants, not the skylight itself. In Suffolk County's freeze-thaw cycles, water gets into small gaps, freezes, expands, and creates larger openings. We prevent leaks by using integrated flashing systems, multiple waterproof barriers, and proper installation techniques. Our installations include step flashing around the sides and continuous flashing at the head and sill, all sealed with high-grade materials designed for Long Island weather.

It depends on your skylight's age and condition. If the frame is structurally sound and the flashing isn't compromised, glass replacement might be possible for newer units. However, most skylights over 15 years old benefit from complete replacement because the seals, hardware, and flashing typically need updating too. We'll assess your specific situation during our free inspection and recommend the most cost-effective solution that actually solves the problem long-term.

Most single skylight replacements take 4-6 hours, depending on roof type and access. We typically complete the work in one day, weather permitting. Flat roof installations may take longer due to additional waterproofing steps. We always protect your home's interior with tarps and work efficiently to minimize disruption. If weather delays the project, we'll secure the opening completely until we can finish the installation safely.

Yes, modern skylights can significantly reduce energy costs when properly installed. Energy-efficient skylights with Low-E glass and proper insulation reduce artificial lighting needs during the day and provide passive solar heating in winter. Velux skylights can be up to 35% more energy efficient than older plastic skylights, potentially saving $10-15 monthly on electricity. The key is proper sizing, placement, and professional installation to maximize benefits while preventing heat loss.

We provide a comprehensive leak-free guarantee on all skylight installations, backed by our workmanship warranty and the manufacturer's product warranty. Velux skylights come with up to 10 years on materials and we warranty our installation work. If your skylight leaks due to our installation within the warranty period, we'll fix it at no charge.
