Skylights in Merced County homes often leak where the curb meets the roof deck, especially on older stock near the Merced County Courthouse and Applegate Park. The hot-summer Mediterranean climate bakes sealant and flashing during long dry periods, then winter rains from the coast find every micro-crack. Technicians check both the skylight frame and the surrounding composition shingles or tiles because water can travel several feet under the underlayment before showing inside.
South Merced properties with low-slope sections around skylights see extra issues from poor drainage during rare heavy storms. North Merced homes near the Merced Theatre area frequently have skylights added during later remodels that were never properly tied into the original roof plane. Proper repair requires lifting the uphill shingles, installing new step flashing, and resealing with compatible materials rated for the temperature swings common between Atwater and Turlock.
Homeowners sometimes attempt interior caulking only, which hides the problem until mold appears on ceilings. A full exterior fix addresses the root cause and prevents repeat calls during the next rain event. Crews always verify attic ventilation and insulation contact around the skylight curb because trapped heat accelerates material breakdown in this climate.
Technician insight
In Merced, the thing that catches most people out with Skylight Leak Repair is how the long dry summers bake the sealant and metal flashing on south-facing skylights in North Merced homes, so the first winter rain finds every gap that formed while the roof looked fine all summer.
South Merced Skylight Leak After First Rain
Water stains appeared on a kitchen ceiling in a South Merced home near Applegate Park after the season's first rain. Inspection showed cracked sealant and lifted flashing around a 15-year-old skylight where summer heat had degraded the materials. New step flashing and high-temp sealant were installed and tied into the surrounding shingles. No further leaks occurred during subsequent storms.
