The average cost to have a professional install Christmas lights on a roof is about $420, with most homeowners spending between $220 and $650. Some companies may charge between $1.25 and $3 per square foot, excluding the cost of the lights. For extensive or complex jobs, the cost can exceed $1,000. While doing it yourself can save money, it is only recommended if you are comfortable working at heights.

Good news, Christmas lovers: you can keep your lights up all year, provided you choose the type. It's critical that you choose holiday lights made for outdoor use, as these can withstand winter weather conditions. In addition, it's best to use LED lights instead of incandescent ones. LED bulbs can withstand temperature shifts and are energy efficient. 

If you are considering leaving your holiday lights up year-round, ask your lighting installer about permanent installation. This project costs around $3,500 but gives you about six to 10 years of LED lights and adds a pleasing aesthetic to your home.

Outdoor Christmas lights cost between $80 to $300 on average without installation. This comes out to about $4 to $50 per strand. You can get a box of outdoor Christmas lights for as little as $20, if you just want to decorate a small area, like a doorway. If you want to go all out and cover your entire home, you'll need between 10 to 20 strands of 100 to 200 bulbs each.

You can take a few steps to prolong the life of your holiday lights. Make sure to replace burnt-out bulbs as quickly as possible to avoid overloading the rest of the circuit and knocking out more lights. Before packing them up each year, plug each strand into the wall to confirm everything is still working. Wrap the lights carefully back into their original packaging or something similar—winding a strand tightly together or leaving it to hang loose in a storage bin can lead to frayed or damaged wiring.
