Stop Leaks at Their Source: Roof Flashing Repair & Replacement by Bestcare
Flashings seal the junctions between a roof and all the vertical surfaces, protrusions, and elements it meets — and they are, by far, the most common source of roof leaks on pitched and flat roofs alike. Thermal movement, UV degradation, physical damage, and poor original installation all cause flashings to lift, crack, corrode, or separate over time. When they fail, water entry is direct and can be severe. Bestcare Facilities Management provides specialist roof flashing repair & replacement services in Nairobi, Kiambu, and throughout Kenya.
Roof flashing repair & replacement requires an understanding of how flashings interact with the building fabric — a lead step flashing, for example, must be correctly dressed into the mortar joint of an adjacent wall while also sitting correctly over the tile course below. Bestcare’s technicians understand these relationships and carry out roof flashing repair & replacement to the correct standard every time.
