Getting multiple roofing quotes is smart.

But asking the right questions matters more than just collecting numbers.

In Michigan, roofing systems deal with:

  • Freeze/thaw cycles
  • Ice dams
  • Heavy snow loads
  • Wind uplift
  • Sudden storms
  • Moisture and ventilation challenges

Two quotes that look similar on price can be very different in scope.

This guide explains what to ask before choosing a roofing contractor — and what the answers should tell you.

1️⃣ Are You Tearing Off the Old Roof or Installing Over It?

This is one of the biggest pricing differences.

Overlay (installing over existing shingles) may look cheaper up front, but in Michigan:

  • It hides decking problems
  • It doesn’t correct ventilation
  • It can shorten lifespan
  • It may void certain warranties

Tear-off replacement exposes hidden issues before they become structural damage.

2️⃣ What Shingle Brand and Model Are You Installing?

Not all asphalt shingles are equal.

Ask:

  • Is this architectural or 3-tab?
  • What wind rating does it carry?
  • What warranty applies?
  • Is the contractor certified with the manufacturer?

3️⃣ What’s Included in the Ventilation Plan?

Many older Michigan homes lack balanced ventilation.

If ventilation is ignored, you risk:

  • Ice dams
  • Premature shingle aging
  • Moisture buildup
  • Warranty issues

If ventilation isn’t mentioned in the quote — ask why.

4️⃣ How Is Flashing Being Addressed?

Flashing failures are one of the most common leak sources in Michigan.

Ask:

  • Will chimney flashing be rebuilt or reused?
  • What about valleys and sidewalls?
  • Is step flashing included?

If flashing scope is vague, that’s a red flag.

5️⃣ How Is Decking Replacement Handled?

Decking (sheathing) may need replacement if:

  • Moisture damage exists
  • Ice dams caused rot
  • Previous leaks occurred

Ask:

  • How much is decking replacement per sheet?
  • How will damage be documented?

Typical decking cost:
$75–$125 per sheet

6️⃣ What’s the Total Cost — and What Could Increase It?

Michigan roof replacement typically ranges:

$8,500 – $18,000+

Depending on:

  • Size
  • Pitch
  • Layers
  • Ventilation
  • Decking
  • Access

If a quote is thousands lower than others, ask what’s missing.

7️⃣ How Will You Protect My Property During Installation?

A professional contractor should explain:

  • Landscaping protection
  • Magnetic nail sweeps
  • Dumpster placement
  • Daily cleanup

Your roof is being removed — your home should not become collateral damage.

8️⃣ Are You Licensed and Fully Insured?

This is non-negotiable.

Ask for:

  • Proof of liability insurance
  • Workers’ compensation coverage

If something goes wrong and the contractor isn’t insured, you could be exposed.

9️⃣ How Long Will the Project Take?

Most asphalt roof replacements take:

1–3 days depending on size and complexity.

✔ Wind
✔ Hail
✔ Falling debris

Insurance may apply.

Final Thoughts

Roofing quotes aren’t just numbers — they’re scope decisions.

The cheapest option isn’t always wrong.

But the cheapest option without clarity usually is.
