10 Signs You Need a New Roof

By the Orlando Roof Inspection team · Updated October 2026 · 8 min read

The clearest signs you need a new roof are curling or missing shingles, piles of granules in the gutters, daylight or leaks in the attic, a sagging roofline, and a roof that's simply reached its age. One sign alone usually means a repair. Several together, especially on an older roof, usually mean it's time to replace. Here are the 10 signs to check, most of them from the ground.

The 10 signs you need a new roof

1Your roof has reached its age

Age is the biggest single clue. Standard asphalt shingles last about 15 to 25 years, architectural shingles 25 to 35, and tile or metal much longer. If your roof is near or past its rated age, start planning even if it still looks okay. See how long a roof lasts by material to find your number.

2Curling or cupping shingles

Shingles that lift at the edges (curling) or rise in the middle (cupping) have dried out and lost their seal. Curled shingles let wind and water underneath and are one of the most reliable signs a roof is wearing out, especially across a large area.

3Granules in the gutters or bald spots

Those sand-like granules are the shingle's protective, UV-blocking layer. A little loss is normal, especially on a new roof. Heavy granule loss — piles in the gutters, or bald, shiny spots on the shingles — means the shingles are near the end of their life.

4Cracked, broken, or missing shingles

A few missing shingles after a storm is a repair. But widespread cracking, or shingles going missing across the roof without a storm, points to age and failure rather than a one-off. The same applies to cracked or slipped tiles.

5Daylight or leaks in the attic

Go into the attic on a sunny day with the lights off. If you can see daylight through the roof boards, water can get in just as easily. Also look for damp insulation, water stains on the underside of the deck, or a musty smell. This is the most urgent sign on the list.

6A sagging roofline

Stand back and look at the roof against the horizon. A straight ridgeline should look straight. Dips, waves, or sagging can mean trapped moisture, rotted decking, or a structural problem underneath — always a job for a professional, and often a sign of replacement.

7Ceiling stains and recurring leaks

Brown rings on ceilings or walls, or a leak that keeps coming back after patches, suggest the problem is the roof system, not a single spot. One stubborn leak can sometimes be repaired; several, or leaks that return, usually mean the roof is failing.

8Worn or damaged flashing

Flashing is the metal that seals the roof around chimneys, vents, skylights, and valleys — and it's where most leaks actually start. Cracked, rusted, or lifting flashing lets water in even when the shingles look fine. On an older roof, failing flashing often arrives alongside other end-of-life signs.

9Moss, algae, or rot

Dark streaks (algae) are mostly cosmetic, but thick moss holds moisture against the roof and can lift shingles. In humid climates, trapped moisture leads to rot in the decking below. If moss has taken hold for years, there may be damage underneath worth inspecting.

10Rising energy bills or a failed insurance inspection

A roof that no longer keeps conditioned air in — from poor ventilation or gaps — can push up cooling bills. And if your insurer's inspection flags the roof, or they won't renew without a new one, that's the clearest financial sign of all that replacement is near.

Repair or replace?

Use this quick rule of thumb:

If you're repeatedly patching the same roof, replacement is usually cheaper in the long run. Not sure which side you're on? That's exactly what a roof inspection settles.

How to check your roof safely (from the ground)

You can spot most of these signs without ever climbing a ladder — and you shouldn't climb one. Roofing is one of the most dangerous jobs in the country, and falls are the leading cause of roofer deaths. Instead:

• Walk the perimeter and look up at the roof planes for curling, missing, or dark worn areas.
• Check the gutters and downspouts for granule buildup.
• Look at the ridgeline from a distance for sagging or waviness.
• Go into the attic for daylight, stains, damp insulation, or a musty smell.
• Scan ceilings and walls upstairs for water stains.

If you see daylight, sagging, or multiple signs at once, call a licensed inspector rather than getting on the roof yourself.
