7 Signs Your Roof Needs Replacing — and 3 That Only Need a Repair
June 23, 2026
By Brad Coley
A roof needs replacing when the problem is the system: age past its service life, granule loss across whole slopes, curling and brittleness everywhere you look, or a deck that has started to sag. It only needs a repair when the problem is a point: a few wind-lifted shingles, one bad flashing, a cracked pipe boot. Here are the seven signs that point to replacement, the three that do not — and how to tell which conversation you are actually in.
7 signs the roof is done
1. It has reached the end of its material lifespan
Architectural asphalt shingles last about 22 to 25 years in Colorado — less than the national numbers, because Front Range roofs absorb more UV at altitude, more freeze-thaw cycles, and more hail. If your roof is in that range, wear you can see is not a maintenance item; it is the material aging out on schedule. Our Colorado roof lifespan guide breaks this down by material.
2. Widespread granule loss
Granules are the shingle's UV armor. When gutters fill with them after every rain and slopes show large dark patches of exposed asphalt, the armor is gone and the asphalt underneath is aging fast. Bald spots on many shingles across multiple slopes is a system failure, not a patch job.
3. Curling, cupping, or clawing shingles
Edges turning up (curling), centers dishing (cupping), or edges turning down while centers lift (clawing) mean the shingles have dried, shrunk, and lost their flexibility. Curled shingles no longer seal to each other, which turns every wind event into a shingle-loss event.
4. Brittle, cracking shingles
Shingles that crack when a technician gently lifts them have lost the oils that keep asphalt pliable. A brittle roof cannot be repaired effectively — every repair disturbs the shingles around it, and brittle shingles break instead of flexing.
5. A sagging roofline or spongy deck
A dip in the ridge or a slope that feels soft underfoot points below the shingles, to water-damaged decking or worse. This is structural, it does not improve on its own, and it makes everything above it a temporary measure. The photo on this article is exactly that situation: rotted decking coming out before the new roof went on.
6. Daylight or widespread staining in the attic
Go up on a bright day and turn the lights off. Pinpoints of daylight through the deck, wet insulation, or dark water trails down multiple rafters mean the roof has been letting water past for a while — the ceiling stains you see in the house are the late innings of that story.
7. Functional storm damage across multiple slopes
Hail bruising and mat fractures spread across a roof cannot be fixed a shingle at a time, which is why insurers total hail-damaged roofs rather than patch them. If a storm did this, you are in a claim, not a repair estimate — and the damage is often invisible from the ground, so it takes an inspection to know.
3 problems that only need a repair
1. A few missing or wind-lifted shingles in one area
Wind grabs shingles at edges, ridges, and corners. If the surrounding roof is healthy and young enough to work on, replacing a localized patch of shingles is a legitimate, durable fix.
2. One leaking flashing
Most roof leaks are not the roof — they are the metal where the roof meets something: a chimney, a skylight, a wall. Re-flashing one penetration on an otherwise sound roof is a repair, full stop. Anyone who quotes a replacement off a single flashing leak without explaining what else is wrong should be asked to explain.
3. A cracked pipe boot
The rubber boots around plumbing vents dry out and split years before good shingles do — Colorado sun is hard on rubber. A split boot causes a surprisingly convincing bathroom ceiling stain and costs very little to fix.
How to make the call
Count the signs, not the years alone. One point failure on a healthy roof: repair it and move on. Two or more of the systemic signs — or one of them plus a roof past 20 years — and repairs become a subscription: you will keep buying them, and the roof will keep failing somewhere new.

FAQ: repair or replace
How do I know if my roof needs to be replaced or just repaired?
The dividing line is whether the problem is isolated or systemic. A few wind-lifted shingles, one leaking flashing, or a cracked pipe boot are point failures — repair them. Widespread granule loss, curling across multiple slopes, brittle shingles that crack when flexed, sagging decking, or a roof at the end of its material lifespan are system failures — repairing one symptom of a failing system buys months, not years.
At what age should a Colorado asphalt roof be replaced?
Architectural asphalt shingles run 22 to 25 years in Colorado field conditions — shorter than national averages because high-altitude UV, freeze-thaw cycling, and hail work on them harder here. A roof in that age range with visible wear is a replacement conversation even if it is not leaking yet, because the next hail storm or the next winter usually makes the decision for you.
Can I just repair hail damage instead of replacing the roof?
It depends on what the inspection finds. Isolated functional damage on one slope can sometimes be repaired; widespread bruising and mat fractures across multiple slopes generally cannot be fixed shingle-by-shingle, which is why insurers total roofs. The answer comes from an inspection, not a rule of thumb — and if a storm caused the damage, it is a claim question as much as a repair question.
