Roofing in Gilroy

Gilroy's climate demands roofing systems built for extremes. Summers push past 95°F, baking asphalt shingles and accelerating UV degradation. Winter fog settles for weeks, trapping moisture against the roof deck. When heavy rain events hit, that moisture becomes a pathway for water intrusion into attics and walls. The low humidity means algae and moss grow slowly, but it also means UV exposure concerns demand materials rated for sustained heat and sun.

Ranch homes built in the 1960s and 1970s dominate Gilroy's residential stock. Most sit on single stories with modest roof pitches—exactly the geometry where ponding and inadequate drainage create soft spots in the deck. Mid-century farmhouse properties on larger lots often have older flashing systems that have corroded or pulled loose. Modern suburban homes constructed since 2000 sometimes show premature granule loss from the heat cycle stress. We've traced leaks in all three, and the pattern is consistent: water finds the weak seam, the transition point, the place where two materials meet.

Storm damage here looks different than coastal areas. Wind isn't the primary threat—it's the thermal shock. A hot roof cooled rapidly by fog can warp shingles or crack brittle underlayment. Hail is rare but devastating when it comes. We inspect for impact pitting, soft spots in the deck from moisture, and flashing separation. The goal is to catch deterioration before it becomes a systemic leak that costs thousands in attic repair.
