Repair vs re-roof
If more than 20% of tiles are broken/spalled, or the roof is 50+ years old, repairs are a false economy. Get quotes for both.

Roof repairs, re-roofing, and gutter replacement costs, plus the old-home gotchas like asbestos and structural batten upgrades.
Roofing is one of the most expensive home trades and also one of the most consequential. A failing roof leads to ceiling damage, insulation rot, and sometimes structural issues. Repairs are often deferred, which usually costs more than addressing the problem when it's small.
The major choice in re-roofing is tile vs Colorbond/metal. Tile suits traditional homes and lasts 50+ years but breaks in hail and leaks at ridge capping. Metal is lighter, lasts 30–50 years, and allows solar and insulation upgrades easily.
The differences between quotes usually come down to a few things. None are visible on day one, and all show up later.
If more than 20% of tiles are broken/spalled, or the roof is 50+ years old, repairs are a false economy. Get quotes for both.
Homes pre-1990 sometimes have asbestos cement roofing or internal sheeting. Removal is licensed and expensive ($5,000–$15,000 typically).
Installing solar on a roof that needs replacement in 5 years is wasted money. Time the re-roof and solar together.
A re-roof is the one chance to upgrade insulation under the sheets cheaply. R-value upgrade adds $1,500–$4,000 but cuts cooling costs long-term.
Hail and wind damage is insured. Take photos before calling the insurer; some claims take weeks and interim tarping is legitimate.
Passive ventilation helps summer attic heat but doesn't always justify its cost. Powered vents are better value in hot climates.
So you know what’s fair to pay, not because cheapest is best.

Quotes well below the entry tier usually skip prep work or use lower-grade product. Quotes above the premium tier are worth asking why. Use this as a fairness check, not a bargain hunt.
A few factors do most of the work. Use them to decode why two quotes for “the same job” can be hundreds apart.
Steeper pitches need harnesses and take longer. Complex roof shapes (multiple gables, dormers) add 20–40%.
Two-storey and scaffold-required jobs add $2,000–$6,000 to re-roof quotes.
Old battens, sagging rafters, or damaged sarking discovered mid-job add to the price. Insist on a quote contingency line.
