1. Preparation Before Installation

Before starting the installation, it’s essential to prepare properly to ensure a smooth and professional job.

Measure the Roofline: Measure the length of the roofline and gables to determine the number of lights needed. Ensure you account for any corners or dips along the roofline.
Choose the Right Bulbs and Spacing: Use C9 bulbs with 12" or 15" spacing for rooflines. Always ensure that the lights are from the same manufacturer to keep brightness and color consistent.
Check the Power Source: Locate outdoor GFCI outlets and ensure they are operational. Plan how many strands will be connected to each outlet following the 80% rule.

2. Installing the Lights

Now that everything is prepared, it’s time to start the installation. Follow these steps to ensure a clean, professional setup.

Start from the Power Source: Begin the installation from the closest power source or GFCI outlet. Secure the male connector of the light strand close to the outlet to avoid cluttered cords.
Use Clips for Rooflines: Use tuff clips, halo clips, or minleon clips to secure lights to shingles or gutters. Ensure clips are spaced evenly for a polished appearance.
Keep the Light Strand Taut: Prevent slack by ensuring the light strand stays tight. Use zip ties to secure any excess cord and keep the lights from sagging.

3. Corners and Peaks

Handling roof corners and peaks correctly will result in a clean, professional look for the installation.

Navigating Corners: Use clips to keep the lights secure around corners. Bend the light cord gently to ensure bulbs are spaced correctly around sharp corners.
Securing Roof Peaks: For peaks, use colored zip ties to mark the peak bulbs for easy identification. Alternatively, cut the back of the clips in half to ensure a snug fit under the shingles. This will make it easier to find and remove peak bulbs during takedown.

💡 Pro Tip: Mark the peak bulbs by using colored zip ties or by cutting the clip in half. This makes it easy to identify the peak bulbs later, which helps during removal and next season’s re-installation.

4. Safety Tips for Roofline Installation

Safety is critical when installing lights on rooftops. Follow these safety guidelines to avoid accidents.

Using Ladders Safely: Follow the 4:1 rule (for every 4 feet in height, place the ladder 1 foot away from the wall). Always ensure the ladder is on stable ground and use leg levelers if necessary.
Wear a Harness: If working on steep or tall roofs, use a harness and tie-off to a stable anchor point.
Avoid Power Lines: Stay clear of overhead power lines and be mindful of any electrical hazards near your work area.

5. Testing and Troubleshooting

Before, during, and after the installation, it's important to test the lights to ensure everything is working correctly.

Test Before Installation: Test each light strand on the ground to ensure all bulbs are working properly.
Test After Installation: Once installed, plug in the lights and inspect them from a distance to check for gaps, dim bulbs, or any sagging.
Troubleshoot Issues: If a section of lights isn’t working, check for loose bulbs or connectors. Replace burnt-out bulbs and check the GFCI outlet if the lights go out.

6. Finishing the Installation

Once the lights are installed, ensure the cords are neatly managed and the display looks polished.

Neat Power Cord Management: Secure extension cords along roofline edges or tuck them into crevices. Hot glue cords to brick or stone surfaces if needed to keep them out of sight.
Final Visual Inspection: Walk around the property to ensure lights are evenly spaced and securely attached. Make any final adjustments to ensure the display looks clean from all angles.

7. Post-Installation Cleanup

Once the lights are up, it’s time to clean the job site and walk the client through the installation.

Remove Tools and Debris: Clear the roof of packaging, zip tie ends, and tools. Ensure all ladders and equipment are safely stowed away.
Client Walkthrough: Walk the client through the display to ensure they are happy with the results. Discuss any additional requests or future installations.
