While a professional installation is always recommended, understanding the process empowers you to assess quality, communicate effectively with your installer, and appreciate the craftsmanship that goes into each SIG Skylight. We specialize in deck mount, curb mount, and fully custom glass skylights, offering superior alternatives to outdated plastic domes. This guide is tailored for those seeking a premium, long-lasting solution for natural light integration.
Pre-Installation: Planning and Preparation
A successful skylight installation begins long before the first cut is made. Thorough planning and preparation are critical for a seamless process and a watertight, durable result. This phase is where attention to detail truly pays off.
1. Site Assessment and Skylight Selection
Before any physical work commences, a detailed assessment of the installation site is necessary. This includes:
- Roof Structure Evaluation: Determine the type of roofing material, rafter spacing, and the condition of the existing roof deck. This ensures the chosen skylight mounting method is compatible and structurally sound.
- Location Planning: Identify the ideal placement for the skylight to maximize natural light and aesthetic appeal while avoiding potential conflicts with attic obstructions like HVAC ductwork or plumbing.
- Skylight Type: Decide between a deck-mounted or curb-mounted skylight. Deck-mounted units are integrated directly into the roof deck, while curb-mounted units require a raised frame (curb) built on the roof. SIG Skylights offers both, with our welded aluminum frame ensuring superior longevity. For those replacing older plastic dome skylights, our aluminum deck-mounted units are an excellent upgrade.
- Size and Customization: While standard sizes are available, SIG Skylights excels in providing custom-sized glass skylights to perfectly fit unique architectural requirements. Learn more about our custom solutions.
- Glazing Options: Consider the performance needs. SIG Skylights exclusively uses high-performance glass, offering superior clarity, durability, and energy efficiency compared to plastic. Explore our advanced glazing options for UV protection and thermal performance.
2. Gathering Tools and Materials
Ensure all necessary tools and materials are on-site before starting. This typically includes:
- The SIG Skylight unit (frame, glass, flashing kit)
- Measuring tape
- Pencils or markers
- Utility knife
- Pry bar
- Circular saw or reciprocating saw
- Hammer
- Drill with various bits
- Caulking gun and appropriate sealant (high-quality, UV-resistant)
- Fasteners (screws, nails appropriate for roofing material)
- Ladder and safety harness
- Roofing nails and shingles (for repairs/integration)
- Underlayment material
- Plywood or OSB for deck repair/framing
- Safety glasses and gloves
3. Safety First
Working on a roof carries inherent risks. Adhering to strict safety protocols is non-negotiable. Always:
- Wear appropriate safety gear, including a harness when working at height.
- Ensure ladders are securely positioned and stable.
- Be aware of weather conditions; avoid working in rain, high winds, or extreme temperatures.
- Have a spotter on the ground if possible.
- Familiarize yourself with best practices for skylight installation safety in Atlanta, GA.
The Installation Process: Step-by-Step
With preparation complete, the physical installation can begin. This process requires precision to ensure a watertight seal and structural integrity.
Step 1: Marking and Cutting the Roof Opening
Precisely mark the location for the skylight opening on the roof. Ensure the opening is square and sized according to the skylight’s rough opening dimensions. Carefully cut through the roofing material, underlayment, and roof sheathing. Be mindful of any existing roof trusses or rafters; if encountered, adjustments to the opening size or framing may be necessary.
Step 2: Framing the Opening (if necessary)
For deck-mounted skylights, you may need to frame the rough opening with lumber to provide a solid attachment point for the skylight unit. For curb-mounted skylights, this step involves building the curb frame according to manufacturer specifications and securing it firmly to the roof structure.
Step 3: Installing the Skylight Unit
Carefully lower the SIG Skylight unit into the prepared opening. For deck-mounted units, ensure it sits flush and is properly aligned. For curb-mounted units, the skylight frame rests on the built curb. Secure the skylight frame to the roof deck or curb using appropriate fasteners, ensuring it is level and plumb.
Step 4: Flashing the Skylight
This is arguably the most critical step for preventing leaks. Proper flashing integrates the skylight with the roofing system. SIG Skylights are designed for straightforward integration, but meticulous attention is required:
- Underlayment Integration: The roofing underlayment should be integrated with the skylight’s flashing system, creating a continuous waterproof barrier.
- Flashing Components: Install the manufacturer-provided flashing kit (or a compatible one), which typically includes sill flashing, step flashing along the sides, and head flashing. Each layer must overlap correctly to direct water away from the opening.
- Shingle Integration: Shingles are installed over the flashing components, starting from the bottom and overlapping upwards, mimicking the natural flow of water down the roof.
- Sealant Application: Apply high-quality, UV-resistant sealant at all critical junctions to create a watertight seal, particularly where flashing meets the skylight frame and where shingles meet flashing.
Contractor Trust Signal: Our SIG Skylights are engineered for robust performance, and our welded aluminum frames are designed to simplify installation while maximizing longevity, earning the trust of contractors across Georgia.
Step 5: Roofing Material Reinstallation
Carefully reinstall the roofing material (shingles, tiles, etc.) around the skylight. Ensure a seamless transition between the new and existing roofing to maintain the integrity of the roof system and prevent water intrusion.
Step 6: Interior Finishing
Once the exterior is secured and watertight, focus on the interior. This involves:
- Framing the Shaft: Frame the light shaft from the ceiling to the skylight opening. Ensure it is plumb and square.
- Insulation: Properly insulate the shaft walls to prevent condensation and improve energy efficiency.
- Drywall and Finishing: Install drywall, tape, mud, sand, and paint the shaft to match the interior decor.
- Trim: Install interior trim around the ceiling opening for a clean, finished look.
Post-Installation: Maintenance and Longevity
Even the best skylight installation requires occasional maintenance to ensure optimal performance and longevity. Regular checks can prevent minor issues from becoming major problems.
Routine Inspections
Periodically inspect the skylight and surrounding roof area for any signs of wear, debris accumulation, or potential leaks. Check the sealant around the frame for cracks or deterioration.
Cleaning
Keep the glass clean to maximize light transmission. Depending on your location in the Atlanta metro area, dust, pollen, and occasional bird droppings can accumulate. Learn about effective skylight cleaning methods.
Addressing Potential Issues
If you notice any signs of water ingress or damage, consult a professional immediately. Early detection is key to preventing more significant damage. Refer to our skylight repair guide for common issues.

Frequently Asked Questions about Skylight Installation
Q1: How long does a typical skylight installation take?
A: A standard skylight installation by experienced professionals typically takes between 4 to 8 hours. However, this can vary depending on the complexity of the roof, the type of skylight, and any necessary structural modifications. Custom installations or those requiring significant roof repair may take longer.
Q2: What is the difference between deck mount and curb mount skylights?
A: Deck-mounted skylights are installed directly into the roof deck, often featuring a self-flashing design. Curb-mounted skylights are installed onto a pre-built frame (a curb) that sits on top of the roof. Curb mounts are often preferred for flat or low-slope roofs and can provide a more robust installation for certain roofing materials. SIG Skylights offers both options, with our welded aluminum construction ensuring durability regardless of the mounting type. Explore the differences further in our guide on Curb Mounted vs. Deck Mounted Skylights.
Q3: Can I install a skylight in any type of roof?
A: Skylights can be installed on most sloped roof types, including asphalt shingles, metal roofing, and tile. Installation on flat or very low-slope roofs typically requires a curb mount for proper water drainage. It’s crucial to assess the roof’s structural integrity and material compatibility before installation. Our team can advise on the best solutions for your specific roofing situation.
Q4: What are the advantages of glass skylights over plastic or acrylic?
A: Glass skylights, like those manufactured by SIG Skylights, offer significant advantages over plastic or acrylic domes. Glass provides superior clarity, is more resistant to scratching and yellowing over time, offers better insulation properties, and is more durable against impact from hail or debris. Our commitment to using high-quality glass ensures a clearer view and a longer-lasting product. Learn more about why SIG Skylights exclusively uses glass.
Q5: How do I ensure my skylight won’t leak?
A: The key to a leak-free skylight installation lies in meticulous flashing and proper sealing. This involves integrating the skylight’s flashing system seamlessly with the roof’s underlayment and roofing material, ensuring all water is directed away from the opening. Using high-quality sealants and following manufacturer guidelines precisely are critical. Experienced professionals, like those who trust SIG Skylights, understand these nuances.
