Two-stage high-risk restoration preserving original terracotta tiles while renewing valleys, box gutters and flashings to stop water ingress.
This heritage church in Kew required careful restoration rather than replacement.
The objective was clear: retain the original terracotta character and mossed patina, while eliminating water ingress and renewing all deteriorated metal components.
Location: Kew, VIC Building Type: Historic Church and Adjoining Education Precinct Architectural style: Late 19th / Early 20th Century Gothic Revival Influence Roof Type: Aged Terracotta Tile Service: Heritage Terracotta Roof Restoration Scope: Two-stage restoration preserving original tiles with full valley, box gutter and flashing renewal Access classification: High-risk steep pitch and complex roof geometry
A Historic Church in Kew’s Heritage Streetscape
Located in Kew, one of Melbourne’s established inner-east suburbs known for significant period architecture, this church forms part of a broader heritage precinct.
The building features classic church proportions – a long gabled nave, intersecting rooflines, arched window detailing and later extensions forming a connected campus.
Its aged terracotta roof contributes strongly to its character. Stripping and modernising the appearance was not an option. The restoration needed to respect the building’s visual integrity while addressing performance failures.
Projects like this sit squarely within our work in heritage roofing in Melbourne, where preservation and technical correction must work together.
Why This Was Classified as High-Risk Work
Church roofs present an elevated risk compared to residential projects:
Steep-pitched main nave roof
Long valley runs, concentrating heavy water flow
Intersecting gables and junction complexity
Height exposure requiring controlled access
Active surrounding precinct with other trades on site
Low-pitched areas required fall protection and guardrail systems. Steep sections required a quick-stage scaffold, roof ladders and boom lift (EWP) access to reach high elevations safely.
High-risk roofing is not just about height – it’s about geometry, access constraints and water management complexity.
Before & After:
Preserving the Original Terracotta Character
The client’s brief was not to modernise the roof. It was to preserve it.
The aged terracotta tiles, complete with natural weathering and moss, were retained wherever structurally sound. Only broken or compromised tiles were replaced.
Rather than pressure cleaning the roof back to a uniform appearance, the restoration focused on keeping its historic patina intact while renewing the failing components beneath.
This conservation-led approach reflects true roof restoration, not cosmetic repair.
Two-Stage Restoration with Full Valley Renewal
The project was delivered in two coordinated stages, working alongside other trades across the precinct.
Key work included:
Full replacement of all valley gutters
Renewal of ageing lead gutters
Replacement of deteriorated protrusions and flashings
Vent ridge repair and selective replacement
Skylight replacement within the church roof area
Re-bedding of ridge capping where required
Flexible pointing applied to reseal ridge lines
Painting of dormer elements to protect exposed timber
Extensive box gutter and valley renewal was critical. Church roof geometry concentrates water along long drainage lines. When metal components fail in these areas, internal damage accelerates quickly.
Renewing these systems ensures the structure remains watertight while the original terracotta finish remains visible from the street.
This is the essence of effective terracotta roofing restoration – preserve the surface, rebuild performance underneath.
Built to Continue Serving the Community
The completed restoration retains the church’s aged terracotta appearance, while eliminating failure points in valleys, gutters and flashings.
Water now exits the roof cleanly. Drainage systems have been modernised. Structural risk has been reduced.
Importantly, the building still retains its original appearance.
In heritage suburbs such as Kew, restoration must protect both function and character. This project demonstrates how targeted renewal can extend the life of historic roofing systems without stripping away their identity.
Planning a Heritage Roof Restoration in Melbourne?
If your property features original terracotta tiles or complex heritage rooflines, restoration may be a more appropriate solution than full replacement.
Book a heritage roof inspection to assess valley condition, metal deterioration and tile integrity before water damage spreads further.
