Which roofing steel suits your distance from the sea?
Enter how far the house is from the surf or from Pittwater and the harbour. See which Zincalume, Colorbond and stainless steel BlueScope lists for that distance, plus the screws, flashings and washing that go with it.
BAL roofing requirements for your roof
Pick your bushfire attack level and roof type for the NSW RFS roof rules (sarking, fascias, flame zone, approvals), CSIRO’s best practice, and what your BAL certificate will specify.
How many downpipes does your roof need?
Enter a gutter run, the distance to the ridge and the roof pitch to work out the roof area, how many downpipes the building code’s tables call for at Sydney rainfall, and which eaves gutters suit.
Know what the roof needs?
Describe the job, what the roof is made of and your suburb. Include the number of storeys and any access issues.
