Why South Lake Tahoe Roofs Fail Differently
South Lake Tahoe sits at 6,200 feet and catches the full brunt of storm systems rolling in from the Pacific. The freeze-thaw cycle is what really does the damage — a roof that's 40°F at noon can drop to 10°F overnight, and any moisture trapped under shingles or in flashing gaps expands and cracks the material. Add in the pine needle buildup from the Jeffery and lodgepole pines around town, and you've got a recipe for rotting valleys and backed-up gutters long before the snow flies. We see the same failures over and over: ice dams at the eaves, lifted shingles from wind funnelling off the lake, and fascia boards rotted from snow sliding off metal roofs with no snow guards. A roof that was fine in Sacramento won't survive a South Lake Tahoe winter, and that's why we spec every job to alpine standards, not flatland ones.
