Ridge Condition Profile
Williamstown Roofing & Weather Profile
What We See in Williamstown
Across Williamstown's 1880s–1920s Victorian and Edwardian period homes stock, Terracotta 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.
Why It Happens
Differential thermal expansion is the key driver of ridge failure on Terracotta Tiles roofs in Williamstown. The tile material and Portland cement have different coefficients of thermal expansion — over hundreds of wet-dry and heat-cool cycles, the accumulated interfacial stress at the tile-mortar junction causes delamination.
How We Fix It
We use a flexible acrylic pointing compound over a polymer-modified bedding mix. The acrylic pointing is UV-stable and maintains elasticity across Melbourne's full temperature range — which is the precise point where rigid cement fails.
