The most common Tahoe gutter story is simple: a gutter that would last decades in Sacramento gets torn off the first time a few feet of wet snow slides off the roof. A snow-rated system is built and placed with that slide in mind.
Local snow loads, in plain numbers
- The City of South Lake Tahoe’s building design criteria list a minimum ground snow load of 150 psf and require ice barrier underlayment.
- Washoe County’s ground snow load table for the Lake Tahoe Basin (which covers Incline Village) lists 315 psf at 6,000 feet and 336 psf at 6,500 feet for typical homes (Risk Category II).
- The Town of Truckee declares the entire town a snow area. Its legacy tables list 260 psf at 5,500 feet on the west side, rising with elevation, and from January 1, 2026, designers may use the ASCE 7-22 snow hazard tool or the Town’s parcel-level snow load map.
Those are design numbers for buildings, not gutters, but they explain why a gutter hanging off the eave sees forces that valley gutters never do.
What makes a gutter “snow-rated”
- Heavier material. Thicker aluminum, steel or copper resists bending and denting.
- Closer hanger spacing. Strong hidden hangers fastened into solid framing at tight intervals spread the load.
- Placement below the roof plane. If an imaginary line extending the roof surface clears the front of the gutter, sliding snow tends to shoot past rather than catch the lip.
- Snow retention above. On metal roofs especially, snow guards or snow fences hold snow in place so it melts off gradually instead of avalanching onto gutters, decks and people.
- Solid fascia and backing. Rotten or thin fascia can’t hold any gutter. A pro checks it first.
When not to install gutters
Sometimes the honest answer is no gutter on a given edge. Steep metal roofs that shed snow fast, eaves above nothing that needs protecting, and edges where an armored dripline already meets TRPA BMP requirements may be better left open. A good contractor will say so.
Drainage
TRPA (the Tahoe Regional Planning Agency) requires developed properties in the Lake Tahoe Basin to install and maintain stormwater Best Management Practices (BMPs) sized to infiltrate a 20-year, one-hour storm, roughly one inch of rain. Roof runoff can sheet off the eave onto an armored dripline, or be collected by gutters, but either way the water has to land somewhere that protects the soil and soaks it in. Gutters concentrate water, so every downspout needs a splash block, rock armor or an infiltration feature beneath it. If you’re adding or changing gutters, ask your contractor how the downspouts will tie into your existing BMPs, and check your parcel’s BMP status on the Lake Tahoe Parcel Tracker.

Frequently asked questions
Do snow guards replace snow-rated gutters?
They work together. Snow guards control how snow leaves the roof; the gutter still has to be strong and placed correctly.
Can my existing gutters be upgraded?
Sometimes. Adding hangers, re-pitching and re-setting the gutter lower can help. Badly bent or undersized gutters are usually better replaced.
Who sets snow loads for my home?
Your local building department: the City of South Lake Tahoe, El Dorado, Placer, Douglas or Washoe County, or the Town of Truckee.
