Flashing failures are responsible for the majority of roof leaks in Southern California homes, yet they are often the last thing homeowners think to check. Metal or rubberized flashing creates the watertight seal wherever a roof surface meets a vertical structure — chimneys, dormers, skylights, parapet walls, and plumbing or HVAC penetrations. When flashing corrodes, separates, or was improperly installed in the first place, water finds its way into the roof system even when the shingles or tiles above it appear perfectly intact.
James's Rancho Cucamonga Roof Repair specializes in diagnosing and correcting flashing problems on all roof types. For step flashing along walls and dormers, we remove the affected shingles or tiles, cut and bend new galvanized or aluminum step flashing, and reinstall the surface material for a weathertight result. For chimney counter-flashing, we re-cut reglets into the mortar joints, insert new copper or aluminum counter-flashing, and seal the reglet with appropriate masonry sealant. Pipe boot flashing around plumbing stacks is replaced with properly sized EPDM or lead boot flashing to form a lasting seal.
Because flashing repairs require removing and replacing the surrounding roofing material, the work requires skill and attention to detail to avoid creating new problems in the process. Our technicians take care to source compatible materials and reinstall surrounding shingles or tiles cleanly, leaving the repaired area indistinguishable from the rest of the roof surface.
