Thinking about a new roof?
Then you need to take a look at some of the design features of your home because these will influence your choice of roof.
Bush fire zones
The devastating costs (financial and social) of bushfires are literally going through the roof. Using the right materials when you replace your roof can help prevent fire from taking hold in your property.
In simple terms; most metal roofing options, including Colorbond and Zincalume, provide superior protection in the event of a bushfire and are appropriate for the highest bushfire rated areas. Additionally, the sarking and insulation may need to be replaced with flame retardant materials such as Bradford’s Fireseal FZ.
The updated BAL FZ (Bushfire Attack Level Flame Zone) requirements cover large parts of NSW including some of the coastal regions. If you live in a bushfire zone your ARC consultant can answer any questions you may have.
The pitch (angle) of the roof may also restrict your choice of materials. Zincalume in a snaplock profile may be used on very flat roofs (as low as 1.5°) whereas nail strip profile panels are not generally used below 7.5°.
Klipock or Trimdeck style sheeting may be required on low pitch roofs. This will be determined at the roof inspection stage and profile recommendations made in accordance with the building code and manufacturers guides.
In general terms; profiles with deeper pans are more suitable for low pitched roofs because of their ability to drain water of the roof more quickly, their seam design, and their concealed fixings.
Proximity to coast
Unfortunately, it’s a fact of life; rust never sleeps. The distance from the ocean to your property is something you need to consider when re-roofing. If your property is more than 1 km but no closer than 200m from the ocean you have a much greater choice of steel roofing panels.
In severe and very severe marine environments (closer than 200 metres) you are restricted to two choices: Colorbond Ultra Steel and Stainless Steel.
Trying to cheat by using materials that don’t suit your environment just doesn’t pay.
Solar panels can be very heavy and require additional structural strengthening. Your solar panel installer may need to disconnect and remove the panels before we start work.
When we replace your roof we will check that your solar panel installation is adequately supported and that any penetrations into your new roof are perfectly protected against water intrusion and wind damage.
Chimneys and skylights
It is usually quite straightforward to lay new roofing sheets around existing chimneys and skylights. Any penetrations will be well protected from the weather using the proper flashings and seals.
