Skylight Work & Replacements on Long Island

Bring natural light into your home safely — professional leak-free skylight installations, flashing repairs, and energy-efficient product replacements designed to withstand severe New York weather.

Why Proper Skylight Installation Matters on Long Island

Skylights are a fantastic architectural addition, flooding interior living areas, kitchens, and master baths with beautiful ambient sunlight. However, cutting a hole into your primary roofline creates an immediate water vulnerability if it isn't sealed flawlessly. Skylights on Long Island face brutal environmental stressors: high-speed coastal winds, heavy winter snow loads, and freeze-thaw cycles that push ice and water under standard flashing lines. Operating from our central office in Manorville, MJB Roofing & Siding ensures your skylights are as structurally sound and weather-tight as the rest of your roof.

Many older homes feature outdated, yellowed acrylic bubble skylights that offer poor thermal insulation and are prone to cracking. Modern upgrades utilize double-paned, argon-gas filled glass with advanced low-E coatings. These units not only protect your home's interior from harmful UV fading but also drastically improve your home's energy efficiency. Whether you need an active leak repaired, an old foggy glass pane replaced, or a new skylight integrated during a roof tear-off, our precision craftsmanship guarantees a dry, secure interior.

Why Choose MJB for Skylight Installations

Standard window installers often lack a comprehensive understanding of roofing systems, while standard roofing crews sometimes skip the delicate internal flashing steps required for a waterproof skylight finish. We bridge that gap completely by bringing specialized roofing and carpentry experience to every skylight opening. We work with industry-leading manufacturers like Velux to provide leak-free warranties. Our fully licensed and insured in-house crews manage the entire job meticulously, giving you absolute peace of mind whenever severe storms roll across Long Island.

Frequently Asked Questions

Should I replace my skylights when I get a new roof installed?

Yes, this is highly recommended. The most cost-effective time to replace a skylight is during a full roof replacement. Trying to reuse an old skylight with a brand-new roof often leads to flashing failure down the road, meaning you would have to pay extra labor costs later to tear up your new shingles just to fix the old skylight. Replacing them together aligns their lifespans and protects your overall roofing investment.

My skylight is leaking. Can it just be resealed with caulk or roofing cement?

Applying caulk, silicone, or roofing tar is a temporary band-aid that will quickly dry out, crack, and fail due to seasonal temperature shifts. True, lasting leak repair requires removing the surrounding shingles, diagnosing whether the frame or the step-flashing has failed, and physically rebuilding the flashing and water barrier system with proper metal components.

What is the difference between deck-mounted and curb-mounted skylights?

A deck-mounted skylight fastens directly to the roof deck sheathing for a low-profile, highly energy-efficient seal. A curb-mounted skylight sits on top of a raised wooden frame (box curb) built onto the roof structure, which is ideal for flat roofs or specialized low-pitch applications. We will assess your specific roof plane and recommend the ideal mounting style for your home.
