Flashing is the system of metal or rubberized material that bridges the joint between your roof surface and any vertical or penetrating element — chimneys, skylights, dormers, vent pipes, and roof-to-wall transitions. Because these joints move slightly with thermal expansion and seismic activity, they are the most statistically likely source of leaks on any San Francisco roof. Deluxe Roof Repair specializes in diagnosing and repairing failed flashings before they cause significant interior damage.
Common flashing failures we address include corroded galvanized base flashing on brick chimneys, separated counter flashing that has pulled away from mortar joints, cracked lead collars on plumbing vent pipes, and delaminated butyl tape at skylight curbs. We use durable materials appropriate to each application — including lead, aluminum, galvanized steel, and rubberized asphalt membrane — and re-bed or re-point masonry as needed to create a lasting seal.
Flashing repair is often the most cost-effective roof service available because it eliminates the leak source without requiring large-scale shingle or tile removal. We carry materials for flat, low-slope, shingle, and clay or concrete tile roofs, serving the full range of residential construction found throughout San Francisco's diverse neighborhoods.

Common Questions
How can I tell if my chimney flashing is the source of my leak?
Chimney flashing leaks typically produce water stains on the ceiling directly in front of or beside the fireplace, or on the attic sheathing immediately downslope from the chimney. If staining appears during rain but you see no obvious missing shingles, chimney flashing is a primary suspect. Our inspection process confirms the source before any repair work begins.
Can flashing be repaired without replacing the surrounding shingles or tiles?
In most cases, yes. Flashing repair involves carefully lifting the adjacent shingle or tile courses, replacing or re-seating the flashing, and re-laying the surface material. Full surface replacement is only necessary when the shingles or tiles themselves are also damaged or too brittle to be re-used.
