Repair or replace? How to know which your roof needs
It comes down to three things: how bad the damage is, how widespread it is, and how much life the rest of the roof has left.
It's the question behind most calls we get: is this a repair, or is it time for a new roof? The honest answer depends on three things — how bad the damage is, how widespread it is, and how much service life the rest of the roof has left. Here's how we work through it on every inspection, so you can think it through too.
Signs a repair is all you need
- The damage is localized — a wind-torn section, a few missing shingles, or one leaky valley — on a roof that's otherwise in good shape.
- Your roof still has years of life left (generally under 15 years old for shingles in our climate).
- A single, findable leak source — flashing around a chimney or a cracked vent boot is the most common culprit we repair.
- Storm damage confined to one slope or one side of the house.
When the roof underneath is sound, a proper repair is the right — and cheaper — call, and we'll say so plainly.
Signs it's replacement time
- Leaks in multiple rooms or across multiple slopes — the system as a whole is failing, not one spot.
- The roof is 20+ years old and shingles are curling, cracking, or shedding granules across whole sections.
- Widespread storm damage that both your insurer and the manufacturer would favor replacing over patching.
- Repairs that keep coming back — if you're calling a roofer every year, the math has already flipped.
- A sagging roofline, which can signal decking or structural moisture damage.
The gray area: age plus damage
The hardest cases sit in the middle — say a 15-year-old roof with real but not catastrophic damage. Here, patching can be throwing good money after bad: the repair might hold, but the surrounding shingles are close behind, and you'll be back. We weigh the cost of the repair against the roof's remaining life and lay out both options with prices, so the decision is yours, not ours.
When a storm is involved, timing matters
If wind or hail caused the damage, there's an insurance clock running. Hail bruising and wind-lifted shingles often don't leak right away — but they've shortened the roof's life, and claim windows don't stay open forever. Documenting the damage early protects your options. We inspect, photograph everything, and help you navigate the claim; the decision always rests with your insurer, but you won't do it alone.
