We carry exclusive certifications from leading manufacturers.
Velux Fixed Skylights — Maximum Daylight
Velux fixed skylights (FS and FCM models) are designed for areas where ventilation is not needed but natural light is essential. Fixed skylights are ideal for hallways, stairwells, walk-in closets, and vaulted living areas where adding a window is impractical or impossible. The fixed design means no moving parts, no maintenance, and the most watertight configuration available.
Velux fixed skylights come in a range of standard sizes that fit between common rafter spacings (16" and 24" on center), simplifying installation. The HighPerformance laminated glass package includes low-E coating, argon gas fill, and a neat glass coating that uses rain to wash away dirt and debris. SPG integrates every fixed skylight with Velux's engineered flashing kit to ensure a watertight seal with your roof system.
Velux Solar Powered Venting Skylights
Velux solar powered venting skylights (VS models) combine natural light with natural ventilation. A built-in solar panel powers the opening mechanism and a pre-installed programmable blind — no electrical wiring required. This makes them ideal for retrofit installations where running new wiring would be disruptive or costly. The solar power system qualifies for the 30% federal solar investment tax credit, reducing the effective cost.
Venting skylights are particularly valuable in kitchens, bathrooms, and upper-story rooms where heat and moisture accumulate. Opening the skylight creates a natural chimney effect that exhausts warm, humid air without mechanical ventilation. The integrated rain sensor automatically closes the skylight at the first detection of moisture, protecting your home even when you're away.
Velux Sun Tunnels — Light for Interior Rooms
Velux sun tunnels bring natural light to interior rooms that have no direct roof access for a traditional skylight — bathrooms, hallways, laundry rooms, and closets with an attic space above. The sun tunnel captures daylight at the roof surface through a low-profile dome and channels it through a highly reflective rigid or flexible tube to a diffuser lens mounted in the ceiling below.
Sun tunnels install in about two hours with minimal disruption to your home. The rigid tube version provides maximum light transfer for straight runs, while the flexible tube accommodates offsets around ductwork, wiring, or framing. Both versions use Velux's engineered flashing system for a watertight roof penetration. Sun tunnels are an affordable way to eliminate dark spots in your home without the cost of a full skylight installation.
Why Proper Skylight Installation Matters
The number one concern homeowners have about skylights is leaks — and the number one cause of skylight leaks is improper installation, not product failure. The interface between a skylight frame and the surrounding roof is a complex waterproofing detail that requires specific flashing techniques, proper sealant application, and correct integration with the underlayment and shingle courses.
SPG's Velux certification means our crews are trained specifically on Velux's engineered flashing systems, which are designed to work as an integrated unit with each skylight model. We use Velux's deck-mounted or curb-mounted flashing kits — never improvised sheet metal work — to ensure the No Leak warranty remains valid. This attention to proper flashing is why SPG skylight installations perform reliably for decades.

How It Works
From first call to final walkthrough — here's what to expect.
In-Home Assessment
We evaluate your roof structure, attic space, and the room below to determine optimal skylight placement, size, and type. We consider roof pitch, rafter spacing, and interior ceiling configuration.
Product Selection & Estimate
We present Velux fixed, venting, and sun tunnel options, discuss glass packages and blind options, and provide a detailed written estimate covering all materials, flashing, and labor.
Professional Installation
Our Velux-certified crews cut the roof opening, install the skylight with the engineered flashing system, integrate with existing roofing materials, and build the interior light shaft if needed.
Final Inspection & Warranty
We verify watertight performance, test venting operation (if applicable), clean all surfaces, and register your Velux No Leak warranty. You receive all documentation and our workmanship guarantee.
What Our Customers Say
SPG installed two Velux skylights in our master bathroom and it completely transformed the space. The natural light is incredible and the No Leak warranty gave us confidence. No issues after two Indiana winters.
We had SPG add a Velux solar powered skylight to our kitchen during a roof replacement. The rain sensor is a great feature and we love being able to vent cooking heat naturally. The solar tax credit was a nice bonus.
SPG installed a sun tunnel in our dark hallway. The difference is remarkable — it feels like there's a window in the ceiling. Quick install, clean work, and no leak worries with the Velux flashing system.
