Terracotta flat shingles key to curved roof design

In the prestigious east Melbourne suburb of Canterbury, architect Phillip Mannerheim and master builder Brian Lee collaborated on a project to create two townhouses with premium appeal that met the price expectations of the market.

Central to the design, which was a finalist in the Roof Tile Excellence category of the 2014 Think Brick Australia awards, is a refined curved roof finished in Boral unglazed Terracotta Shingle tiles.

According to architect, Phillip Mannerheim, the curved roof using the flat shingle was aesthetically appealing and cost efficient. “Our greatest challenge was to create a design that met neighbourhood and council approval. We were confident the Boral Terracotta Shingles would work on the curved design we were proposing.

“As the project also had a short time-frame for completion and needed to be commercially viable, skill and precision were required for installation and the result was exactly what we were after. The cost savings were also very pleasing and the sale price was a positive reflection of the design,” commented Mannerheim.

Builder Brian Lee agreed. “The shingle roof tiles provided the look of a slate roof at less than half the cost. The curved roof was achieved by using straight timbers. The mansard roof trusses were made with a double pitch of 30° and 50° and the curve was created by installing an infill chord between the two pitches. A full size set out of each tile course was done on site and this was critical to creating the perfect curve.

“The Boral Terracotta Shingles were specified on style, function and price. The combination of good design and quality products is the key to selling in any market. Using Boral Terracotta Shingles enabled the project to the completed on time and on budget.”

Why specify terracotta roof tiles?

  • An extensive range of colours and finishes and the unique design of individual tile profiles provides design flexibility to complement a wide range of architectural styles.
  • Terracotta roof tiles are crafted from natural clays and kiln-fired to 1100oC for exceptional character and strength.
  • Colour is locked in during the kiln-firing process, so the tiles retain their original appearance with age.
  • Built to last, Boral Terracotta roof tiles come with a 50 year performance guarantee. The tiles can withstand harsh climatic conditions and marine environments.
  • Tiles do not rust or corrode, so little maintenance is required. In the event of damage, tiles can be replaced individually, which is cost effective when compared to large metal sheets.
  • They are salt-safe and fire, wind and frost-resistant. Terracotta roof tiles can safely be used in bushfire prone areas, including the highest prone areas (BAL-FZ).
  • Roof tiles have a sound reduction potential twice that of steel sheet roofing[1]. Their density helps reduce external sound such as aircraft or road noise, and rain and hail.
  • The thermal mass of clay and concrete materials, when used correctly and in addition to sarking and good solar design, can improve insulation.
