Ridge Condition Profile
Thornbury Roofing & Weather Profile
What We See in Thornbury
A lot of the 1920s–1950s Californian Bungalow and inter-war period homes housing in Thornbury was laid with a very lean mortar mix for the ridge bedding — standard practice at the time, but not engineered for longevity. After a few decades those mixes crumble at the edges and lose their mechanical bond to the Terracotta Tiles profile.
Why It Happens
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.
How We Fix It
Where bedding failure is concentrated on wind-exposed sections — typically the west and northwest-facing ridges — we re-bed only the affected caps rather than quoting a full-roof repoint. Matching the scope to the actual problem is how we maintain repeat business.
