Roof Repointing in Laverton

Across Laverton's 1950s–1970s post-war brick veneer stock, Concrete Tiles were routinely laid on a rigid cement bed with no polymer flex additive. As the roof frame settles and seasonal temperature variation works on the structure, that rigid bed cracks — the ridge is always the first section to show it.

Salt crystallisation is a mechanical weathering process. Salt in solution enters mortar pores when the roof is wet and crystallises as it dries. The crystals expand under formation pressure and generate internal stress that fractures the mortar from the inside — the damage is invisible until the surface spalls.

Every Laverton job starts with a full ridge walk — every Concrete Tiles cap assessed before we touch anything. We mark every section of compromised bedding and quote the actual scope of work, not an estimate from a ground-level inspection that misses the sections only visible underfoot.
