Ensure you have a safe environment for them to work on, and there aren’t items such as logs, build-up of yard materials, missing or damaged shingles, and weak areas on the roof. Communicate any known electrical issues with contractors at the beginning of the project, and consider hiring an electrician to fix those. Finally, if you are attempting the project yourself, do so when there isn’t any rain, and you can safely get your footing on the roof using proper equipment, such as an extension ladder. Don’t attempt this alone, and have a helper nearby to assist.

There are many types of Christmas lights to choose from when working with a light installer. The main types available for outdoor lighting are dome, LED, incandescent, and C9, and your lighting professional’s choice will depend on the location and overall design. 

C9 lighting is typically the most expensive option, ranging from $15 to $70 per 25-foot strand. These usually have fewer bulbs per strand, so you might need more than expected to cover a large area. Dome lighting is usually the most cost-effective option, ranging from $6 to $15 per 25-foot strand. These bulbs are smaller and rounder than other options, creating a softer look.

The length of time shouldn’t matter much if you stick with lightweight Christmas lights and similar decorations. Those shouldn’t pose risks to your stucco. You should avoid attaching anything to your stucco that could fall because it’s too heavy, which may take part of the stucco with it. Some methods, like using double-sided tape or adhesive hooks, will naturally wear out over time and lead to falling lights, so don’t expect to leave these lights up year-round.

Professionals use the same methods found in this guide unless they’re decorating a particularly large Christmas tree. In that case, they may also make use of tools like extension poles to get the job done.
