⚡ Quick answer
You likely need a new roof if you're seeing several of these at once: granules collecting in the gutters, curling or brittle shingles, more than one leak, daylight or damp wood in the attic, and a roof age past about 20 years. In the wet Umpqua Valley, stubborn moss and dark streaking add to the case. A single problem area can usually be repaired; a stack of these signs together means replacement. A free inspection settles it — no guessing from the ground.
We roof homes from Roseburg down to Canyonville and out toward Camas Valley, and the questions we hear most start the same way: "Is my roof actually bad, or am I overreacting?" Fair question. Roofs in western Oregon take a beating that a homeowner in a dry climate never sees — 30-plus inches of rain a year, 130-plus days of it, then a hot dry summer that bakes what winter soaked. That freeze-soak-bake cycle is why our roofs age faster than the number on the shingle wrapper suggests.
Here are the ten signs we check, roughly in order of how much they worry us.
1. Granules in the gutters
Those sandy granules are your shingles' sunscreen and armor. When they wash into the gutters and pool at the downspout outlets, the asphalt underneath is exposed and starts to harden and crack. A handful after a brand-new install is normal shed. Cupfuls, year after year, from a roof over 15 is your shingles telling you they're wearing out.
2. Curling, cupping, or clawing shingles
Healthy shingles lie flat. When the edges lift (curling) or the centers rise (cupping), the mat has dried out and lost its flexibility. Our wet-dry swing is brutal on this. Once shingles curl, wind gets under them and rain gets behind them — and no amount of cleaning flattens them back down.
3. Bald, cracked, or missing shingles
Shiny black patches mean the granules are gone entirely. Cracks running across the tab, or shingles simply missing after a wind event off the Coast Range, are open doors for water. A few missing shingles is a repair; widespread cracking across the whole field is not.
4. More than one leak
One leak around a single pipe boot or a chimney is a targeted repair. But when you're chasing leaks in more than one spot, the underlayment and flashing across the whole roof are likely at end of life. Chasing multiple leaks on a failing roof costs more over two winters than replacing it once.
5. Daylight or damp wood in the attic
Grab a flashlight on a bright day and look up in the attic. Pinpoints of daylight through the sheathing, dark water staining on the wood, damp insulation, or a musty smell all mean water is getting past the roof surface. This is one of the most honest tests there is, and most homeowners never do it.
6. Sagging ridge or deck lines
Sight along the ridge and the roof planes. A straight roof should look straight. Waves, dips, or a sagging ridgeline can mean the decking underneath has absorbed moisture and lost strength — a structural issue that only gets worse and costs more the longer it waits.
7. Moss that keeps coming back
This is the local one. Our shaded, damp north-facing slopes grow moss the way the rest of the country grows nothing. Early moss can be treated and prevented — see our moss prevention guide. But thick, established moss lifts shingle edges, wicks water under them, and holds it against the deck. If it returns every winter no matter what, the shingle surface has usually given up.
8. Dark streaks and staining
Those black streaks running down the roof are usually algae feeding on the limestone filler in older shingles. On their own they're cosmetic, but they signal a shingle surface that's aging and holding moisture — exactly what you don't want in a climate that stays wet for months.
9. Rusted, cracked, or pulling flashing
Flashing seals the joints where the roof meets walls, chimneys, and valleys — the spots that leak first. Rusted, cracked, or lifting flashing (or old tar smeared over it as a "fix") is a common failure point on Douglas County homes. Our flashing guide covers what good flashing looks like.
10. Age past about 20 years
Even a roof that looks okay from the street is on borrowed time once it passes 20. Most asphalt roofs here last 18–25 years, not the full 30 — our roof lifespan guide explains why. If you know your roof is 20-plus and you're seeing any of the signs above, it's worth a look before the next atmospheric river finds the weak spot.
Repair or replace?
One problem, on an otherwise healthy roof, under 15 years old? Almost always a repair. Several signs together, on a roof past 20? Usually a replacement — and paying to patch it repeatedly rarely pencils out. Still unsure, our repair-or-replace decision guide walks the exact math.
Why Oregon roofs show these signs sooner
Homeowners moving to the Umpqua Valley from drier states are often surprised their roof is failing "early." It isn't early for here. The Coast Range wrings moisture out of every storm before it reaches us, our winters keep roofs damp for weeks, moss thrives in the shade of Douglas firs, and then July and August bake the shingles dry. That cycle, not just years, is what wears a roof out. A roof that would last 28 years in Arizona genuinely gives you fewer here — which is why local inspection habits matter more than a wrapper warranty.
If you'd rather stay ahead of all this, our Home Care Membership (from $49/month) includes annual inspections, debris and moss checks, and 10% off repairs — the cheapest way to get the full 25 years out of a roof in this climate.
What to do next
If you counted more than two or three of these signs, don't wait for the leak to pick the timing for you. We'll get on the roof, photograph everything, and give you a straight answer — maintain, repair, or replace. Right now every new roof includes $500 off, plus free whole-home gutters on qualifying roofs ($20k+), so if it is time, it's a good time. Start with a fast ballpark using our instant estimate, then book the free on-roof inspection to confirm.
Quick answers
What's the number-one sign a roof is done?
Widespread granule loss combined with curling shingles on a roof past 20. That pairing means the shingle surface has worn through across the whole roof, not just one spot.
Should I climb up to check myself?
No — our wet, mossy roofs are slick and steep-checking from the ground and the attic is safer. Leave the walking to a crew that's tied off. Our free inspection covers it.
Is a repair ever a waste of money?
Yes, when it's a patch on a roof that's failing everywhere. Two or three repairs on a 22-year-old roof usually cost more than putting that money toward a replacement.
