UTICA Roof signature project
This private residence presented an uncommon convex roof geometry, a timber ceiling below and a client requirement to avoid plywood within the roofing substrate. The resulting roof demanded careful coordination between architectural intent, fabrication technique and weatherproofing.
The design challenge
Designed by Chalk Architects, the roof uses an uncommon convex curved form. The geometry meant that familiar flat or single-pitch roof details could not simply be repeated across the surface.
Interfaces were developed around the intended roof profile, the site constraints and the need to provide added protection for the timber ceiling installation beneath it. Every change in direction had to be considered as part of one continuous weathering system.
Material strategy
Treated plywood is commonly introduced when a curved surface needs a continuous backing. For this home, the client wanted a roof build-up without plywood to remove concern about termite infestation.
The roof substrate and metalwork were therefore developed around that requirement rather than treating it as a later substitution.
Fabrication approach
Special techniques were used to form the metal decking and roofing panels to the convex profile.
Additional measures were incorporated to reduce oil canning, the visible waviness that can appear in broad metal surfaces, because the unusual roof geometry makes surface control more demanding.
