Timing & Booking
Book in December, Light for Three Weeks
October 29, 2026
The first measurable snow in Frisco usually lands in October. By mid-November, north-facing roof planes in Breckenridge and Keystone are holding accumulation that won't fully leave until April. That single fact drives almost everything about when Christmas lights get installed up here — and it's why a call placed in December buys you a very different season than a call placed in September.
A December install gives you about three usable weeks
Count it out. If a crew gets to your house on December 12, your display runs December 12 through the first week of January. That's roughly three weeks lit, and then takedown. You paid for a design, a full install, materials cut and fit to your rooflines, and the whole apparatus comes down before the snow's even interesting.
Book in late September or early October and the same display goes up during the first half of November — before the ground freezes hard, before the roof is loaded. You get Thanksgiving through New Year's. Same install, same materials, more than double the nights lit. The cost per lit evening is the number that actually matters, and December booking is the expensive way to buy it.
For short-term rental owners, the math gets sharper. Summit County booking calendars fill Thanksgiving week and run hot through the holidays. A property that's dark during the Thanksgiving window and lit on December 12 missed the exact stretch where exterior photos earn their keep.
Snow on the roof changes what we can install, not just when
Once accumulation sets on a standing-seam metal roof, a few things stop being options. We can't see the seam spacing to plan clip placement. Clip-on hardware that grips a standing seam needs a clean, dry seam to seat properly — snow and ice in the channel means the clip either won't close or won't hold through the first thaw-freeze cycle.
On asphalt shingle roofs, the problem is different but no better. Shingle clips slide under the tab. With snow pack and an ice dam built along the eave, that edge isn't accessible without doing damage, and nobody should be chipping ice off a roof edge to hang lights.
So a December install on a loaded roof often means a reduced design. Ground-level work, trees, railings, column wraps, the sections of eave we can reach safely. That may be a display you're happy with — plenty of homes look great that way — but it's a decision made by the weather, not by you. An October walkthrough lets you choose.
Short daylight is a real constraint, not an excuse
Summit County loses usable installation hours fast through November. By the first week of December, we're working with daylight that's gone by 4:30, and on a west-facing slope in Silverthorne the working light disappears earlier than that. A crew that could complete two or three homes a day in early November completes fewer once the sun's cutting out mid-afternoon.
Add wind. Lakeside properties around Dillon and anything on an exposed ridge get afternoon gusts that make ladder work on a steep pitch a bad idea. We stop. That's the right call every time, but it means December work gets pushed, and pushed work stacks behind other pushed work. The calendar compresses from both ends.
What January takedown has to do with your December decision
Takedown is part of the service, and it happens in January regardless of when the lights went up. That's the piece people don't price in when they wait. The install date is flexible. The removal date is not — it's governed by weather windows, HOA expectations in several Summit County developments, and the simple fact that a display sitting on a roof through February is a display sitting under three more months of snow load and freeze-thaw.
Which means the season has a fixed back wall. Everything you lose by booking late, you lose permanently. You don't get it back in January.
What to do in September and October
Concrete steps, in order:
- Get the walkthrough on the calendar now. Design happens on-site. We look at your actual roof — pitch, material, seam spacing, where the power is, which runs face the road. That conversation is worth having in daylight on a dry roof.
- Check your HOA before you design. Several Summit County developments have rules on timing, color, and what can attach to exterior surfaces. Finding out in November means redesigning in November.
- Locate your exterior outlets and confirm they work. GFCI outlets that have been sitting unused since last winter are a common surprise. Better to find a dead one in October.
- Second-home and rental owners: send your booking calendar. If the house is occupied Thanksgiving through New Year's, we schedule install around guests, not through them. That requires lead time.
- Decide your install window, not just your install date. Tell us the two weeks that work. Weather will move things inside that window, and a window gives everyone room.
Why a Frisco crew matters in the last week of November
Summit Mountain Lights is based in Frisco, and the crew has been hanging lights professionally for more than fifteen years — including on metal roofs at elevation, in wind, with a storm on the radar. When a November front closes the window for two days, we know which homes to move and which to hold, because we're twenty minutes from all of them. We're not driving up from the Front Range to make a judgment call about your roof.
That proximity is worth the most during the exact weeks when December bookings pile up. It's worth even more if you never need it, because you booked in October and your lights went up on a dry roof.
If you want a display running by Thanksgiving, now is the time to get on the schedule. Tell us your address and roughly how many feet of roofline you're thinking about, and we'll come look at it.
