Flat Roof Refurbishment

service-image

RJ Evans Flat Roofing Limited provides flat roof refurbishment for commercial and residential buildings to restore waterproofing performance, correct existing defects, and extend the service life of ageing flat roofing systems. Flat roof refurbishment is the process of improving an existing flat roof without necessarily removing and replacing the complete roofing system. The work begins with an assessment of the waterproof membrane, insulation, roof deck, drainage, flashings, penetrations, outlets, upstands, edges, and adjoining details to determine the condition of the roof and the refurbishment required.

Flat roof refurbishment may include repairing damaged membranes, replacing saturated insulation, improving drainage, renewing defective flashings, treating localised deterioration, and installing a compatible overlay or liquid-applied waterproofing system. The selected solution depends on the existing roof construction, substrate condition, extent of moisture damage, and remaining serviceability of the roof build-up. The completed refurbishment restores the continuity of the waterproof barrier, prevents water from reaching the insulation and roof deck, and protects internal building areas from moisture damage. RJ Evans Flat Roofing Limited carries out flat roof refurbishment to preserve suitable existing roof components, reduce the disruption associated with complete replacement, and keep commercial and residential flat roofs watertight, durable, and protected throughout their extended service life.
