Roof Problems San Ramon Homeowners Actually Face

San Ramon sits in a warm inland pocket where summer sun bakes the south slopes and winter storms roll in fast off Mount Diablo. The housing stock splits between 1970s Spanish-style stucco homes and 2000s two-story tract builds, and each one fails in its own way.

• Ceiling stains after a storm — water wicks past worn step flashing at a wall or dormer, soaks the underlayment, and rots the plywood decking beneath it.
• Granules in the gutter — asphalt shingle surfaces shed mineral granules as they age, and once the mat shows through, end-of-life wear moves fast.
• Curled shingles on south-facing slopes — UV exposure dries the sealant strip, wind gets under the field course, and the shingle peels loose.
• Sagging rooflines — a moisture-soaked rafter or rotted sheathing lets the roof deck settle, and that is framing work, not a patch.
• Moss and dark streaking on north slopes — algae still grows on shaded shingle faces here, holding moisture against the mat long after rain stops.
• Leaks at vents and pipe boots — cracked rubber collars and hardened mastic fail years before the shingles do, so we reseal or replace the boot flashing.
• Overflowing gutters and stained fascia — debris blocks a downspout, water backs up under the drip edge, and the fascia and soffit above it decay quietly.

Winter rain, not ice dams, is the real threat in this valley. Ice dam damage belongs to the Sierra, but the same water-intrusion mechanics apply when flashing is tired.
