It’s helpful to identify the right lights first before learning how to hang Christmas lights on your house. Here are our tips for choosing the perfect lights for your roof, windows, and outdoor spaces

Know the Difference Between Indoor and Outdoor Lights

Not all Christmas lights are suitable for both indoor and outdoor use. Unless specified otherwise, most lights should only be used indoors.

The first step to figuring out how to hang Christmas lights outside is to choose a product specifically marked “outdoor-safe”. Look for lights that have been approved by trusted companies such as UL (Underwriters Laboratory) or ETL (Edison Testing Laboratories).

Find the Right Type of Lights To Hang Outside

Christmas lights come in a wide array of colors, sizes, and special features to suit different decorating styles. Survey the outdoor area you intend to decorate and determine which light type will accentuate the space best. Learn more about common light types to help narrow down your options. You can opt to combine different kinds for a dazzling display.

Regardless of the type of outdoor Christmas light you choose, also take into consideration the bulb type. LED lights emit less heat and consume less energy compared to traditional incandescent bulbs. They may be a bigger investment upfront, but LED bulbs last longer and can help you save on electricity costs and replacement bulbs.

Measure Your Hanging Space

Measure the area where you plan to install the Christmas lights. Then, compare this with the length of the light strings to determine how many strands you’ll need.

Insider’s Tip

Use a tape measure to get the length of your roof line, window edges, and other exterior surfaces before calculating how many light strings you will need. Save the measurements so you can access the information the following year.

The standard length for a 50-light strand is 25 feet, while a 100-light strand usually measures 50 feet. For example, if you need to cover a 120-foot space, you’ll need at least five 50-light strands or three 100-light strands. You may need more if you're hanging the lights in a pattern.

Lights outside add an enchanting glow to exterior spaces. Wrap them around outdoor christmas decorations, trees, or greenery, or hang in a pattern from eaves and railings. Remember to use the proper tools and follow safety precautions for a trouble-free installation.

Materials

  • Measuring tape
  • Ladder
  • Extension cords
  • Christmas light clips and insulated hooks

Steps

  • Step 1|Untangle the lights

    Carefully untangle all the lights and lay them out on a dry surface outside.

  • Step 2|Test the bulbs

    Plug in the light strings and check if all the bulbs are working. Also do a cursory check on your extension cords and other electronic accessories, if using. Make sure there are no frayed wires or other damage.

  • Step 3|Measure your section

    If you’re thinking about how to hang Christmas lights on the roof with festoon lights, use a tape measure to know the length of the section you’ll hang lights on and compare it against the length of the light string to make sure it will fit. When assessing how to hang Christmas lights on gutters using cascading lights, measure even spaces between light string placements for a uniform effect.

  • Step 4|Attach the hooks

    Secure the Christmas light hooks and clips to your chosen location. Spread out the hooks evenly to prevent the light strings from drooping or gaping. If you’re wondering how to hang Christmas lights around windows, you may opt to use Christmas light hooks or window clips with either adhesive backing on the window frame or suction cups against the glass itself.

  • Step 5|Hang the light strings

    Carefully attach the light strands using the clips or the hooks. Make sure each section is free of tangles or twists.

  • Step 6|Plug in the lights

    Once the lights are in place, plug them in to ensure that the entire set-up works. Step back and check your display for any inconsistencies.

Insider’s Tip

Invest in a CHRISTMAS LIGHT STORAGE BOX to make both setup and storage of your Christmas light strings hassle-free. Spools inside the box help avoid tangles and minimize bulb breakage.

How To Hang Christmas Lights on Roof Without Gutters

If you’re curious about how to hang Christmas lights on roofs without gutters, you can use clips to attach the lights to the shingles. You can also use ones with adhesive backing. Keep in mind, however, that light clips made of plastic may become brittle and break over time after prolonged sun and weather exposure

Observe Extra Caution When Using Ladders

Make sure to set the ladder on dry and even ground. Have someone outside with you to hold the ladder securely in place from the bottom.

Only Use Lights As Directed

Read the manufacturer’s guide on the proper use of your light strings. Verify that they can be used outdoors. Do not pull, twist, tie together, or weigh down lights to lessen the risk of damage and fire.

Minimize Electrical Hazards

Avoid overloading extension cords. To be on the safe side, only use 75% of the available plugs and remember to use one plug per outlet. Use insulated light looks or nails to secure the light strings safely.

When the holidays are over, make sure to store your Christmas lights properly so you can use them for years to come. Invest in a special LIGHT STRINGS STORAGE BAG so you don’t have to deal with tangled wires every season. For more tips, check out our guide on HOW TO STORE CHRISTMAS LIGHTS.
