San Diego's mild Mediterranean climate brings intense year-round UV that degrades skylight seals and flashing faster than inland regions. Homes in North Park and Mission Valley often date to the 1950s–1970s with original acrylic or polycarbonate units that craze and leak at the curb. Salt-laden air from the coast accelerates corrosion on aluminum frames in Pacific Beach and La Jolla, while downtown high-rises face additional wind-driven rain issues at roof penetrations.
Common repairs involve replacing butyl or silicone perimeter seals, rebedding step flashing into existing composition or tile, and addressing condensation channels that fail on older units. Edge cases include skylights installed too close to HVAC curbs or near the USS Midway Museum area where vibration from nearby traffic loosens fasteners over time. Always verify that new glazing meets current San Diego County energy codes for solar heat gain when replacing glass.
Homeowners frequently overlook minor curb cracks until water reaches interior ceilings near Balboa Park or the San Diego Zoo. Attempting DIY sealant from big-box stores often traps moisture and voids any remaining manufacturer warranty on the unit. Proper repair requires lifting adjacent roofing material without disturbing the underlayment, especially on steeper Mission Valley slopes.
Technician insight
In San Diego the thing that catches most people out with Skylight Repair is how quickly salt air from the coast eats through aluminum frames in La Jolla and Pacific Beach while the rest of the county stays milder. Homeowners in North Park often wait until interior staining appears near Balboa Park before calling, by which point the underlayment has already taken damage.
North Park Curb Leak
