A roof replacement is one of the largest home improvement investments you'll make. Here's how to know when it's time, what it costs, and how to hire the right contractor.
Signs Your Roof Needs Replacement
Age is the most reliable indicator: asphalt shingles last 20–30 years; if yours are approaching that age, start planning. Other signs include curling or buckling shingles, granules in the gutters (shingles shedding their protective coating), daylight visible through the attic, sagging areas, and multiple leaks. A single leak in an otherwise sound roof can often be repaired; widespread issues usually mean replacement.
Repair vs. Replace: How to Decide
If your roof is under 15 years old and the damage is localized, repair is usually the right call. If it's over 20 years old, has widespread damage, or has already been repaired multiple times, replacement is almost always more cost-effective in the long run. A good roofing contractor will give you an honest assessment — get a second opinion if you're unsure.
Roofing Material Options and Costs
Architectural asphalt shingles are the most popular choice at $8,000–$18,000 for a typical home — durable, widely available, and available in many colors. Metal roofing (standing seam or metal shingles) costs $15,000–$40,000 but lasts 40–70 years with minimal maintenance. Slate and clay tile are premium options at $25,000–$75,000+ but can last 100+ years. For most homeowners, architectural asphalt offers the best value.
What's Included in a Roof Replacement
A complete roof replacement includes tear-off of the existing shingles (usually one layer; two layers adds cost), inspection and replacement of damaged decking, installation of ice and water shield at eaves and valleys, felt underlayment, new shingles, and replacement of flashing around chimneys, skylights, and vents. Make sure your quote includes all of these — some contractors quote shingles-only and add the rest as extras.
How to Hire a Roofing Contractor
Roofing is one of the most fraud-prone home improvement categories — storm chasers and fly-by-night contractors are a real problem. Hire local contractors with verifiable reviews and a physical address. Verify their license and insurance (general liability and workers' comp). Get at least three quotes. Never pay more than 10–15% upfront. Be wary of contractors who show up unsolicited after a storm.
Insurance Claims for Roof Damage
If your roof was damaged by a covered event (hail, wind, falling tree), your homeowner's insurance may cover some or all of the replacement cost. Document the damage with photos before any repairs. File your claim promptly — most policies have time limits. Be cautious of contractors who offer to 'work with your insurance' or waive your deductible — this is insurance fraud and can void your coverage.
