End Chimney Leaks: Professional Chimney Flashing Repair by Bestcare
Chimneys are among the most complex and leak-prone features on any pitched roof. Where the chimney stack passes through the roof, there are multiple junctions — front apron, rear back gutter, and side step flashings — all of which must remain watertight simultaneously. When any one element fails, water can penetrate in significant volumes. Bestcare Facilities Management provides specialist chimney flashing repair services in Nairobi, Kiambu, and throughout Kenya, resolving chimney-related leaks definitively.
Chimney flashing repair is not a DIY task. The multiple overlapping elements of a chimney flashing system must be correctly sequenced and installed for the system to work as a whole. Improperly repaired chimney flashings are one of the most common causes of repeat leaks, often because only one failing element was addressed while others were left in a deteriorated condition. Bestcare’s technicians assess all elements of the chimney flashing system, not just the visibly damaged part.
Chimney Flashing Components Bestcare Repairs
Front Apron Flashing — The horizontal flashing across the downslope face of the chimney; re-dressed and sealed where lifted or cracked.
Step Flashings — The interlocking series of L-shaped flashings along each side of the chimney; replaced where corroded or displaced.
Back Gutter Flashing — The flashing forming a gutter behind the chimney to channel water around the upslope side; re-seamed and sealed where failed.
Counter Flashings / Cover Flashings — The upper flashings dressed into chimney masonry mortar joints; re-pointed and re-dressed where pulled out by thermal movement.
Chimney Stack Pointing — Mortar joints on the chimney stack itself are repointed where deterioration is allowing water to absorb through the masonry.
