Roofing in Baulkham Hills

A straightforward single-family roof takes 1-3 days for asphalt shingles or metal sheeting, and up to 1-2 weeks for tile, slate or complex multi-plane roofs. Weather delays are normal — a competent crew will never strip more roof than they can waterproof the same day.

Full replacements commonly require a building permit or regulatory compliance; small like-for-like repairs usually don't. Rules vary by country and municipality, and a legitimate contractor will know and handle the paperwork — treat 'we don't need a permit' on a full reroof as a flag to double-check.

Often worth it: the access equipment is already up, edge details integrate cleanly, and combined pricing beats two separate jobs. If your gutters are under ten years old and sound, keep them — but have the roofer protect them during tear-off and note their condition in writing.

Sometimes — an overlay saves tear-off cost but hides deck problems, adds weight, and often shortens the new roof's life and warranty. Many codes and manufacturers limit roofs to two layers. Tear-off costs more upfront and is usually the better long-term decision; get both options priced.

A full replacement runs roughly AUD $10,000 for a small single-storey home to $40,000+ for a large two-storey, with metal (Colorbond) and concrete tile the mainstream options. Roof restoration — clean, rebed, repoint and repaint — is the cheaper alternative at about $2,500-$7,000 when the roof is structurally sound.

Restoration keeps the existing tiles or sheets: high-pressure clean, replace broken tiles, rebed and repoint ridges, then seal and paint. It costs a fraction of replacement and adds 10-15 years to a sound roof, but it cannot fix widespread corrosion, cracked battens or failed sarking.
