Structural Roof Repairs: Decking & Sheathing by Bestcare
Beneath the tiles, sheets, or membrane of your roof lies the decking or sheathing — the structural board layer that supports the roof covering and ties the rafter structure together. When this layer is compromised by moisture ingress, rot, insect damage, or physical impact, the entire roof system is at risk. Bestcare Facilities Management provides expert roof decking & sheathing repair services in Nairobi, Kiambu, and throughout Kenya.
Roof decking & sheathing repair is not visible work — it takes place beneath the surface covering — but it is among the most structurally significant repairs a roof can receive. Soft, rotted, or missing decking allows roof coverings to flex, crack, and eventually fail, while also compromising the thermal and acoustic performance of the building.
How Bestcare Approaches Roof Decking & Sheathing Repair
Inspection and Mapping — The extent of decking damage is mapped before any covering is removed, using probing and moisture testing to identify all affected areas.
Safe Access and Cover Removal — Roof coverings are carefully removed from the affected area and stored for reinstatement where possible.
Decking Replacement — Rotted, split, or missing sections of plywood, OSB, or timber boarding are replaced with treated materials fixed correctly to the rafter structure.
Rafter Inspection and Repair — Underlying rafters and purlins are inspected and repaired where moisture has caused rot or insect damage.
Reinstatement — Roof coverings are reinstated and sealed, with any damaged tiles or sheets replaced as part of the roof decking & sheathing repair process.
