Seal Wall-to-Roof Junctions: Step Flashing Repair by Bestcare
Wherever a pitched roof meets a vertical wall — at a side extension, a lean-to, a dormer, or a party wall — a series of interlocking L-shaped flashings called step flashings is used to seal the junction. Each step flashing is designed to integrate with a single course of roof tiles above and below, and is dressed into a mortar joint in the adjacent wall. When these flashings fail — through corrosion, thermal movement, or mortar joint deterioration — leaks at the wall-to-roof junction are the result. Bestcare Facilities Management provides expert roof step flashing repair services in Nairobi, Kiambu, and across Kenya.
Roof step flashing repair is precision work. Each step flashing must be correctly sized, correctly lapped with its neighbours, correctly integrated with the tile course below, and correctly dressed into the mortar joint above. Improper step flashing repair — common when non-specialist contractors attempt the work — often results in a repeat leak within one or two rain seasons.
Step Flashing Repair Methods Bestcare Uses
Mortar Chase Re-Cutting — Where the mortar joint the flashing must be dressed into has been filled with a repair compound, Bestcare cuts a clean new chase for the flashing lead.
Individual Step Replacement — Corroded or damaged individual step flashings are removed and replaced with new, correctly formed pieces.
Full Run Replacement — Where an entire step flashing run has deteriorated, all pieces are replaced in a single operation.
Counter Flashing Installation — Where counter flashings are absent or have failed, Bestcare installs new cover flashings over the step flashing system.
