What Are the Signs Your Roof Needs Replacing?
Curling, cracking, or missing shingles, granules collecting in your gutters, and daylight or damp showing in the attic are the signs that matter most. One sign alone rarely means replacement, but several together usually do.
You don't need to climb on your roof to use this guide. Most of these signs show from the ground, from a window, or from inside the attic with a flashlight. Real photos from our jobs are below each one, so you know exactly what you're looking for.
What do the warning signs actually look like?
Curling and clawing shingles.
Edges turning up, or middles humping while edges stay down. Either way the shingle has dried out and quit lying flat, and wind gets under it next.
Cracked shingles.
Cracks mean the shingle has lost its flexibility. Scattered cracking across a slope is age, not accident, and it doesn't reverse.
Missing shingles or tabs.
One missing tab after a windstorm is a repair. Tabs going missing every time the wind picks up means the seal bond across the roof is failing.
Granules in the gutters.
Granules are the shingle's sunscreen. When they collect in gutters and downspout splash areas, the shingles are wearing thin. Bald spots you can see from the ground are the late stage of the same thing.
Flashing problems.
Rusted, lifted, or patched-over metal where the roof meets chimneys, walls, and valleys. Flashing failures cause a huge share of the leaks we see, sometimes on roofs whose shingles are fine.
Daylight or damp in the attic.
Go up on a bright day and turn off the light. Daylight through the boards, water stains, damp insulation, or a musty smell all mean water is getting past the roof. This one moves you from watching to calling.
Sagging.
A dip in the roof line means something structural is giving underneath. This is the one sign on this list that shouldn't wait for a convenient week.
Which signs usually are not a big deal?
Honesty cuts both ways, so here's the other list.
Black streaks. Usually algae, not failure. It's a cosmetic issue on most roofs and it can be cleaned. It doesn't mean your shingles are done.
Granules from a newer roof. New shingles shed loose granules for a while after installation. That's normal, not wear.
Moss in small patches. Worth addressing, since moss holds moisture against the shingles, but a patch of moss is a maintenance item, not a replacement verdict.
One lifted or missing tab. A repair, plain and simple. Anyone who quotes a full replacement off a single missing tab is answering a question you didn't ask.
When should you call someone?
When signs start stacking. A roof past 15 with granule loss and a couple of curling slopes is telling you something. Anything in the attic, any leak, or any sagging skips the watching phase entirely. And if you're seeing signs and wondering whether it's a fix or a full roof, that question has its own guide: should you repair or replace it.

Warning sign questions, answered straight
How can I check my roof without climbing on it?
From the ground with binoculars or your phone camera zoomed in, from an upstairs window that overlooks a slope, and from inside the attic with a flashlight. That covers most of this list. Leave the ladder work to people who are paid to fall off roofs carefully.
Are black streaks a sign my roof is failing?
Usually not. They're algae, they're common here, and they're mostly cosmetic. If streaks bother you, cleaning is an option. Replacement isn't the answer to algae.
My roof is missing one shingle. Is that serious?
It's a repair, and worth doing soon so water doesn't get to the layers underneath. It isn't a replacement conversation unless it keeps happening.
What does hail damage look like?
Dark bruises or dents in the shingle surface, often with granules knocked loose, and dents in soft metal like gutters and vents. It can be hard to spot from the ground, which is one reason inspections after big storms are worth it.
