Every November, the same debate plays out in driveways across the Pacific Northwest. One person wants to string the lights themselves to save money. The other points at the two-story roofline, the moss, and the rain in the forecast. Both have a point.
The honest answer isn’t “always hire a pro” or “always do it yourself.” It depends on your house, your roof, and how you value your time. So let’s lay out the real numbers and the real risks, and let you decide.
What DIY Actually Costs
The sticker price on DIY looks great. A few boxes of lights, some clips, done. But that’s not the whole bill.
Quality commercial-grade LED strands — the kind that survive a wet PNW winter and last more than one season — run $25 to $50 per strand. A typical single-story home needs 8 to 12 strands to cover the roofline. Add clips, timers, extension cords, and replacement bulbs, and a first-year DIY setup commonly lands between $300 and $600. That’s before you’ve climbed a single rung.
Then there’s storage. Lights have to live somewhere for ten months a year, and tangled, improperly stored strands are the number one reason people rebuy every season. The cheap boxes that fail by year two end up costing more than the good ones you only buy once.
And the biggest cost most people ignore: time. Measuring, testing strands, untangling last year’s mess, climbing up and down, fixing the dead section you didn’t notice until everything was hung — a typical install eats a full weekend day. Takedown in January eats another. If your Saturday is worth something to you, factor it in.
The Safety Math on PNW Rooflines
This is where the Pacific Northwest changes the equation.
Falls from ladders send hundreds of thousands of people to the ER every year in the U.S., and holiday decorating is a documented spike. The common thread isn’t recklessness — it’s ordinary people on ladders they use twice a year.
Now add our conditions. PNW rooflines are often steep. They’re frequently wet. Many are slick with moss or algae by December. A damp composite shingle on a 7/12 pitch is not a surface you want to test while reaching one-handed with a strand of lights. Gutters full of wet leaves don’t make great handholds either.
If your home is a single-story rambler with a gentle pitch and dry footing, DIY is genuinely reasonable. If you’re looking at a two-story peak, a steep gable, or anything you’d hesitate to walk on in running shoes, the safety cost of DIY stops being theoretical. A single fall — a broken wrist, a cracked rib, worse — erases every dollar you saved and then some.
Worth noting: if your roof is mossy enough to be a footing hazard, it’s also overdue for attention. A clean roof lasts longer and looks better under lights. Our roof cleaning service handles exactly that, and many homeowners pair the two before the holidays.
What Professional Installation Costs
Professional holiday light installation in the Pacific Northwest typically runs $500 to $1,500 for a residential home, depending on roofline length, height, and complexity. Larger or more elaborate homes go higher.
Here’s what’s actually in that number, because it’s easy to see the price and miss the value. A professional install usually includes commercial-grade lights sized and cut to your exact roofline, custom clips that won’t damage your shingles, professional installation by people who do this every day on tall and steep roofs, timers set to your preference, mid-season maintenance if a section fails, and full takedown and storage in January so you never touch a ladder.
That last part matters more than people expect. With DIY, January is a second cold, wet climb you have to do yourself. With a pro, the lights simply disappear when the season ends.
When you stack the full DIY bill — quality lights, storage, two days of your time, and the risk premium of climbing a wet roof — against a done-for-you install with lights, labor, maintenance, and takedown included, the gap narrows fast. For a tall or steep home, professional installation is often the better value, not just the safer one.
How to Decide for Your Home
A few honest questions cut through it:
How tall and steep is your roof? Single-story and gentle leans DIY. Two-story, steep, or moss-covered leans professional.
How much is your time worth? Two weekend days, twice over, is the real labor cost. Some people enjoy it. Many don’t.
What’s your tolerance for risk? Only you can price a fall. But on a wet PNW roof, that risk is real, not hypothetical.
Do you want to deal with January? Takedown in the cold and rain is the part everyone forgets when they’re feeling festive in November.
There’s no wrong answer. Plenty of PNW homeowners string their own lights every year and love it. Plenty of others decide the time and risk aren’t worth it. Both are valid.
The Bottom Line for PNW Homeowners
DIY makes sense when your roof is low, your footing is dry, and you genuinely enjoy the project. Professional installation makes sense when your roof is tall or steep, your weekends are scarce, or you’d simply rather not climb a wet roof in December.
