Signs you need a new roof — and what a replacement costs

Most asphalt-shingle roofs last 20 to 30 years, and the shingles themselves are typically warrantied for 25 to 30 years (Consumer Reports). If your roof is past 20 and showing any of the signs below, you're in replacement territory — not because a contractor says so, but because the materials have reached the end of their rated life. The job is to catch it before water damage turns a $9,000 roof into a $9,000 roof plus $6,000 of drywall, insulation, and framing repair.

Eight signs your roof is failing

1. The roof is simply old

Age is the single best predictor. Find your home's records or ask a previous owner. An asphalt roof installed before 2005 is statistically near or past its service life. If neighboring homes built the same year are getting re-roofed, yours is on the clock too.

2. Curling, cupping, or clawing shingles

Healthy shingles lie flat. When edges turn up (curling) or the center lifts (cupping), the asphalt has dried out and lost its weatherproofing. This usually shows up on the sun-facing slope first. Scattered curling can be a repair; widespread curling across a whole slope means the material is done.

3. Bald spots and granules in the gutters

Asphalt shingles are coated in mineral granules that block UV. As shingles age they shed granules — you'll find them collecting in gutters and at downspout outlets, looking like coarse black sand. A roof that's losing granules heavily is losing its sun protection and will degrade quickly from there.

4. Missing, cracked, or broken shingles

A few shingles lost in a storm is a repair. But brittle shingles that crack when walked on, or repeated losses after every wind event, signal a roof that no longer has the flexibility to stay put.

5. Daylight or sagging 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 too. A sagging roof deck — a visible dip or wave in the rafters — points to trapped moisture and rotting decking, which almost always means replacement plus structural repair.

6. Water stains on ceilings or walls

Brown rings or streaks on upstairs ceilings mean water is already getting past the roof. The stain is usually downhill from the actual leak, so the entry point is rarely directly above the mark — which is exactly why DIY patching so often misses.

7. Damaged or rusted flashing

Flashing is the metal that seals joints around chimneys, vents, and valleys — the spots where most leaks actually start. Cracked sealant or rusted flashing can sometimes be repaired on its own, but on an old roof it's a sign the whole system is aging out.

8. A spongy, soft feel underfoot

If walking the roof feels soft or bouncy, the decking underneath has absorbed moisture and weakened. That's a structural issue, not a surface one, and it's a clear replacement signal.

Repair or replace? How to decide

A useful rule of thumb from roofing contractors: if the damage is confined to less than about 30% of the roof and the roof still has years of rated life left, repair it. If the roof is past 20 years, or damage spans multiple slopes, replacement is usually the better long-term spend — repeated repairs on a dying roof are throwing money at a problem that's only going to get worse.

The other factor is the decking. If a contractor finds rotted decking once the old shingles come off, that adds cost — but it also means a repair would have failed anyway. Always get the inspection and the finding in writing.

What a new roof costs in 2026

For a full asphalt-shingle replacement on an average single-family home, most homeowners spend $5,700 to $13,000, or roughly $4.50 to $11.00 per square foot installed (HomeAdvisor, Angi 2026 cost data). Premium materials push higher: standing-seam metal commonly runs $14,000 to $25,000+, and slate or tile can exceed that.

Scope	Typical range	What's included
Minor repair	$150 – $1,500	A few cracked or missing shingles, small flashing fix, sealing one leak
Major repair	$1,500 – $7,000	Larger leak, sagging section, partial re-decking, multiple problem areas
Full replacement	$5,700 – $13,000+	Asphalt shingle tear-off + replacement, average single-family home

Your actual number depends on roof size and pitch, how many old layers have to be torn off, material choice, and local labor rates. The single biggest lever is square footage — roofers price in "squares" (100 sq ft each), so a bigger or steeper roof costs more to cover and is more dangerous to work, which raises labor.

Before you sign anything

• Get three written quotes for the same scope — same material, same warranty, same tear-off.
• Confirm the contractor is licensed and carries liability and workers' comp insurance, and ask for proof.
• Ask what happens if they find rotted decking — get the per-sheet price in writing up front.
• Be cautious of any "storm chaser" who knocks after bad weather and pressures you to sign same-day.

That's exactly what Homative is built for: tell us about your roof and we'll match you with up to three pre-screened, licensed local roofers so you can compare quotes on the same scope — with no obligation to hire.
