Flat Roof Specialists: Puncture & Blister Repair by Bestcare
Punctures and blisters are the two most common defects in flat membrane roofing systems, yet they are also among the most frequently misdiagnosed and poorly repaired. A blister that is simply painted over or superficially patched will fail again within months; a puncture that is not properly sealed at its edges will admit water despite the patch. Bestcare Facilities Management provides technically correct roof puncture & blister repair services in Nairobi, Kiambu, and throughout Kenya, restoring membrane integrity that lasts.
Roof blisters form when moisture or air becomes trapped between layers of a built-up membrane system. As the roof heats in the sun, this trapped moisture vaporises and expands, pushing the membrane upward into a dome shape. The stretched membrane eventually ruptures, creating a puncture — or the junction with adjacent membrane lifts, creating a seam failure. Correct roof puncture & blister repair addresses both the blister itself and the underlying moisture source.
Bestcare’s Puncture & Blister Repair Method
Blister Opening — The blister dome is carefully cut to release trapped vapour and expose the substrate.
Substrate Drying — The substrate beneath the blister is dried before any repair materials are applied, preventing re-blistering.
Patch Application — Purpose-made membrane patch material is applied over the repair area with a minimum 150mm overlap in all directions.
Edge Sealing — All patch edges are sealed with compatible adhesive or heat-welded to prevent edge lifting.
Puncture Sealing — Roof punctures from foot traffic, dropped tools, or mechanical damage are prepared, cleaned, and patched in the same manner.
