In Michigan, roofs don’t usually fail all at once.

They decline in stages.

One year it’s a small leak.
Next year it’s a few missing shingles.
Then it’s curling tabs.
Then interior staining.

At some point, homeowners start asking:

“Should I repair it — or is it time to replace the whole roof?”

This guide helps you decide based on:

  • Roof age
  • Damage patterns
  • Cost comparison
  • Michigan climate stress
  • Long-term ROI

Step 1: Consider the Age of the Roof

In Michigan, asphalt shingles rarely last their full “label life.”

If your roof is:

  • Under 10 years old: Usually repair territory
  • 10–15 years old: Depends on condition
  • 15–20+ years old: Often replacement territory

If the roof is already nearing the end of its expected life, repairs may only delay the inevitable.

Step 2: Look at the Type of Damage

🔹 Repair Is Often Enough If:

  • Damage is localized
  • A few shingles are missing
  • Flashing is compromised
  • A small leak has a clear source
  • The rest of the roof looks healthy

🔹 Replacement May Be Smarter If:

  • Leaks are recurring
  • Shingles are curling or cracking
  • Blow-offs happen repeatedly
  • Granule loss is widespread
  • Decking feels soft or spongy
  • The roof looks uneven or wavy

Step 3: Compare Repair Cost vs Replacement Cost

Typical Michigan Repair Costs

  • Leak repair: $350–$1,200
  • Flashing repair: $400–$1,800
  • Shingle blow-off: $250–$900
  • Ventilation upgrades: $800–$2,500

If you’re paying for repairs every year, those numbers add up quickly.

Typical Michigan Replacement Cost

Full asphalt roof replacement:
$8,500–$18,000+

The Repair Trap (Common Michigan Scenario)

Year 1: $600 repair
Year 2: $900 repair
Year 3: $1,200 repair
Year 4: Leak returns + decking damage

At that point, you’ve spent several thousand dollars — and still need replacement.

Sometimes replacing intentionally is cheaper than repairing repeatedly.

Step 4: Evaluate Ventilation & System Health

Sometimes what looks like “roof failure” is actually:

  • Poor attic ventilation
  • Moisture imbalance
  • Installation defects

If the system is compromised, patch repairs won’t solve the root issue.

What About Insurance?

If damage was caused by:

✔ Wind
✔ Hail
✔ Storm impact

Replacement may be partially or fully covered.

Insurance guide:

If damage is age-related, insurance typically does not apply.

Quick Decision Matrix

Condition Likely Best Option
Roof under 10 years old + localized damage Repair
Multiple leaks + 15+ year old roof Replace
Repeated blow-offs Inspect full system
Heavy curling + granule loss Replace
Flashing-only issue Repair
Soft decking detected Likely replace

When an Inspection Makes the Most Sense

You should schedule an inspection if:

  • The roof is 15–20+ years old
  • Repairs have happened more than once
  • Damage followed a storm
  • You’re unsure whether repair will buy time
  • You want a clear long-term plan

AllPoint Construction will inspect, document, and explain your options — without pressure.

FAQ: Repair or Replace in Michigan

Is it bad to repair an old roof?
It’s not bad — but it may not be cost-effective if the roof is near end-of-life.

Can I replace only half my roof?
Sometimes possible, but color match, structural integrity, and warranty considerations apply.

How do I know if decking is damaged?
Decking issues are usually found during inspection or tear-off.

How long does roof replacement take?
Most asphalt roofs take 1–3 days.
