Here are a few other reasons why roof tiles are a better choice…

Will not rust, warp or corrode
Roof tiles will never rust, warp or corrode, a frequent problem with other roofing materials.

Provides thermal insulation
Roof tiles keep you comfortable in your home all year round, while helping save money and the environment through energy savings.

Impervious to frost and ice
Roof tiles are ideal for those living in colder climates. They are impervious to the effects of frost and ice, and will never crack or warp, no matter how cold it gets.

Tank water safe
Roof tiles are made from naturally occurring clays, which means the water running off your roof into rainwater tanks is clean and safe.

Salt Safe
Roof tiles are ideal for coastal locations that endure the wind, spray and salt of the ocean. All Monier Roofing roof tiles are salt safe and will not corrode over time.

Provides acoustic insulation
Roof tiles assist in keeping unwanted noise out. Their advanced insulation properties mean that the only noise in your home will be the noise created by you and your family.

Monier Terra cotta Colour never fades
Monier Terracotta roof tiles will never fade. Even after years on your roof with the sun beating down and the wind and rain battering away, Monier Terracotta tiles retain their colour.

  • Will painting my roof prevent my roof tiles becoming porous?

    CSIRO Division of Building Construction and Engineering have stated that concrete tiles do not become porous with age. All concrete tiles absorb a small amount of water however that in no way compromises the integrity of the roof. Roof restoration through painting of your concrete roof tiles should be done to improve the appearance of your roof only it will not increase the lifespan of your roof tiles. Terra cotta roof tiles should never be painted..

  • What are dry valleys?

    In the past in Victoria the valleys on roofs were bedded and pointed where the roof tiles met the valley irons. This practice stopped in the 1990’s as it was determined by the industry that the cement in the valleys can crack easily with the expansion and contraction of the valley irons. Once the cement falls out of place in the valleys it can block the water flow and cause water ingress into the ceiling. Thus the current standard is that the valleys are left dry.

  • Will salt air damage my terra cotta roof tiles?

    In past eras terra cotta roof tiles could become salt affected if installed near the sea. This is no longer a concern as current technology used to produce terra cotta roof tiles means that modern tiles are not affected in any way by exposure to salt air. Monier terra cotta roof tiles have a 50 year performance and colour guarantee.

  • Will moss and lichen damage my roof tiles?

    Moss and lichen does not eat into roof tiles or damage your roof in any way. Some homeowners do not like the look of the lichen on their roof and choose to get their roof cleaned. This is easily done using a high pressure water cleaning system.

  • How often should i get my roof checked?

    You should get your roof checked at least once a year, especially coming into winter as the climate provides us with a lot of wind and rain.

  • What are the benefits of sisalation paper/sarking?

    There are three main benefits which can be gained by installing sisalation paper to your new roof.

    > Sisalation paper can add up to an extra R1 insulation benefit.
    > It adds and extra layer of waterproofing in the event that there is damage to your roof and a roof tile had been broken.
    > Sisalation paper will assist in keeping dust and debris out of your ceiling space. Helpful if you plan on using this space for storage.

    Overall a great product which will give you a premium roof.

  • How can I make my roof as energy efficient as possible?

    A major source of a home’s heat gain or loss is through the roof, which in turn places a huge load on energy requirements for cooling and heating. The density of roof tiles combined with the use of effective insulation, ventilation and solar passive design principles creates a more effective barrier against the climate.

  • Do we recommend spraying roofs with colour?

    Depending on the material and method used it is acceptable to re-spray concrete roof tiles to enhance the colour. However, it must be understood that this will not enhance performance and if the roof is old, you could be much better off re-tiling. Never re-spray terracotta tiles, as the colour coat applied will peel away from the glazed surface over time.
