FAQs
Why are salt-laden winds such a problem for roofs in Mascot?
Mascot sits only a few kilometres from Botany Bay, so almost every on-shore breeze carries microscopic salt crystals. These crystals settle on roof sheets, tiles, flashings and fixings. Salt is hygroscopic—it attracts and holds moisture—so metal components stay damp for longer, accelerating oxidation and rust. Painted surfaces chalk faster, mortar joints dry out, and even membrane roofs can suffer UV/salt breakdown. Without a roof that is specifically engineered and maintained for coastal conditions, premature leaks and structural damage are common.
What roofing materials do you recommend for maximum resistance to salt corrosion?
For metal roofs, we specify marine-grade Colorbond Ultra, Zincalume AZ200, or aluminium standing-seam panels, all of which have enhanced metallic coatings that inhibit rust. If you prefer tiles, we use glazed terracotta or salt-sealed concrete tiles because their smooth surface sheds salt more easily. All fixings are 316 marine-grade stainless steel or Class 5 galvanised screws. Flashings and gutters are matched to the same corrosion-resistant alloy so there is no galvanic reaction. Finally, we apply a breathable, salt-blocking sarking underlay to further protect the roof frame.
How often should a coastal roof in Mascot be inspected or serviced?
We recommend a professional roof inspection every 12 months, with a targeted clean at least once every 18–24 months to remove any salt crust that regular rain has not washed away. After major storms or strong southerly systems, a spot check is wise to make sure wind-driven salt has not lifted flashings or compromised sealants. Keeping gutters clear of salty debris is critical; blocked gutters trap brine and dramatically shorten metal life. Routine servicing can add 10–15 years to the lifespan of a roof in our coastal zone.
Will choosing a salt-resistant roofing system cost more, and is it worth it?
Up-front, marine-grade products are about 8–15 % more expensive than standard roofing materials. However, the life-cycle savings are substantial. A conventional roof in Mascot may need major repairs at the 10- to 12-year mark, while a salt-resistant installation typically delivers 25–30 years of service before similar work is required. When you factor in reduced maintenance, fewer call-outs, and a higher resale value for your property, most homeowners recover their additional investment within the first decade.
Do you provide warranties or guarantees on your salt-laden winds roofing?
Yes. Roofing Done Right issues a dual protection package: • A 25-year manufacturer’s warranty on marine-grade Colorbond Ultra or aluminium panels (materials). • A 10-year workmanship warranty covering installation quality, water-tightness, and adherence to Australian Standard AS 1562.1. Both warranties remain valid as long as you follow our recommended annual maintenance schedule, which we document and remind you about each year.
How long does a typical salt-resistant re-roof or new roof installation take in Mascot?
For an average 3-bedroom home (about 180 m² of roof area), a full re-roof with marine-grade metal usually takes 3–4 working days, weather permitting. Tile-to-metal conversions may require an extra day for structural batten adjustments. New builds are scheduled in line with the overall construction program but generally need only two site visits: one for foil-sarking and battens, and one for sheet laying and flashings. Because coastal weather can change quickly, we always secure a temporary waterproof membrane each night to protect your home.
