7 Signs You Need a Roof Replacement (Not a Repair)

1. The roof is past 18–20 years old

In this climate, that's the realistic range where an architectural asphalt shingle roof starts running out of useful life, regardless of its 25–30 year rating — see how long an asphalt roof actually lasts here. Age alone isn't disqualifying, but it changes how a repair should be evaluated: a patch on a roof already near the end of its life buys less time than the same patch would on a 10-year-old roof.

2. You've had more than one repair in the last two or three years

A single repair doesn't point toward replacement. Repeated repairs — a new leak each season, or the same area failing again after being fixed — usually mean the roof as a whole is deteriorating, and each repair is treating a symptom of that broader decline rather than an isolated cause.

3. Granule loss is widespread, not localized

Some granule loss in the gutters after a storm is normal. Bald patches across multiple slopes, or granules accumulating heavily every time it rains even without a recent storm, mean the shingle mat itself is exposed and breaking down broadly — a condition that spreads rather than stays contained.

4. Multiple leak points, not one

A single leak traced to one flashing failure or one damaged section is a repair. Leaks showing up in two or three unrelated areas of the house point to a roof failing as a system rather than at one identifiable weak point.

5. Sagging anywhere on the roofline

A visibly sagging ridge or a dip between rafters usually indicates deck or structural involvement, not just a surface shingle problem. This is one of the clearer signals that a repair alone won't address the underlying issue.

6. Widespread storm damage across the roof, not an isolated section

Hail bruising or wind damage concentrated on a handful of shingles is a repair. Damage spread across most of the roof's surface area — see Storm Damage Roof Repair for what that inspection looks for — usually makes more sense as a full replacement than as dozens of individual shingle repairs.

7. Ice dams every winter despite gutter and attic work already done

If ventilation and insulation improvements haven't stopped recurring ice dams, the roofing system underneath — underlayment, ice-and-water shield coverage, deck condition — may no longer be providing enough of a backup layer, which is a replacement-level issue rather than something a repair can fully resolve.

When it's genuinely a repair

A roof under about 15 years old with a single, identifiable cause of damage is almost always a repair situation, not a replacement one. The signs above are about pattern and scope, not a reason to replace a roof that's still doing its job in most respects.
