Advice for Renovators: Replace or Restore The Roof?

It’s the important question facing every renovator: restore or replace? When it comes to tiled roofs, the decision is heavily guided by future plans for the home, according to building products supplier, Boral. “Most renovators will have the option to either replace a tiled roof entirely, or restore it. There are a number of factors to consider, including the long-term plans for the home,” said Harry Tanner, product manager of roofing at Boral.

“Undertaking a complete re-roof can be a valuable investment for those looking to stay in their home for the long term. Although the initial cost may be higher than restoring the roof, homeowners benefit from the longer warranties typically associated with installing new roof tiles. For example, Boral terracotta tiles are supplied with a 50-year warranty.

“A re-roof is also an opportunity to upgrade roofing materials. Homeowners may wish to replace old concrete roof tiles with durable terracotta tiles for longer lasting colour. Terracotta tiles are manufactured using a special firing process that locks in colours to help retain the tiles’ appearance over time,” said Tanner. The benefits of new roof also extend beyond aesthetics, explains Tanner. “Sarking can only be installed during construction and can contribute to improved thermal performance and comfort in the home. The reflective foil insulation is laid beneath tiles to enhance weather proofing and energy efficiency.”

Renovators wanting to spruce up their home ahead of a sale or short term renovation, may  prefer to restore existing roof tiles. “Restoration can be a cost-effective and relatively quick option for rejuvenating a home’s exterior. However, the aesthetic benefits may be shorter lived when compared to a re-roof. “Restoration typically involves cleaning and painting existing tiles. In some cases, the tiles may be resistant to new finishes, resulting in cracks and chips over time. Warranties on a roof restoration vary by supplier, but tend to range between five to eight years, which is short in relation to the life of a house,” said Tanner.

The condition of an existing tiled roof will also guide the decision to replace or restore. “In some cases, homeowners may not have a choice. Where a roof is completely dilapidated by heavy weather or extreme age, for example, a re-roof may be the only option,” advises Harry. Tanner encourages homeowners to seek professional advice. “Those undertaking a renovation are encouraged to have tiled roofs checked by a roofing professional, especially if original materials have been in place for 25 years or more. This can identify any damage or potential issues, and the installer can provide advice on options for repair or replacement.”
