Poor attic ventilation in Napa lets warm moist air condense on cold roof decking. Drip by drip, it soaks insulation and ceilings all winter. It looks like a roof leak but the roof is innocent.
Copper lines under Napa slab foundations corrode and pinhole over decades. Warm spots on the floor and the sound of running water with taps closed are the classic tells. Napa County slabs from the 70s and 80s are prime candidates.
Tanks older than 10 years rupture without warning, dumping 40-plus gallons. Napa homes with heaters in garages or attics face the worst fallout.
Discharge lines that freeze shut in Napa winters send pumped water right back into the pit. The pump runs, the pit overflows, the basement floods. Buried or insulated discharge lines solve it.
Pumps, filters, and heaters develop slow leaks that saturate surrounding soil in Napa yards. The water migrates to foundations and slabs. Equipment pads deserve a look every season.
