Shingle Roof Replacement Basics
Asphalt shingles cost less than steel, come in many colors and are easy to patch after a storm. The weak points are wind and ice. The National Weather Service in the Quad Cities logged an 86 mph gust at the Davenport airport in the August 10, 2020 derecho. Scott County, Iowa landed in that storm's federal disaster declaration, FEMA-4557-DR.
Winter is the quieter threat. Local code calls for an ice barrier underlayment, puts frost depth at 42 inches and labels the weathering risk "severe." Freeze-thaw cycles work water under loose tabs, and ice dams build at cold eaves.
When Homeowners Ask for Shingle Roof Replacement
A Davenport shingle estimate usually covers these items, plus upgrades worth asking about.
- Architectural shingles. Thicker, layered shingles with a dimensional look, and the usual pick on re-roofs today.
- Class 4 impact-resistant shingles. Rated to take harder hits than standard shingles. They're optional, never a code requirement, and cost more; ask for both prices.
- FORTIFIED construction. A voluntary building standard aimed at keeping the roof on and water out in severe weather. It adds steps and cost; ask your roofer whether they build to it.
- Ice barrier at the eaves. Davenport's code requires it. The membrane goes under the shingles along the lower edge, where ice dams push meltwater back up the roof.
- Flashing, drip edge and vents. New metal at chimneys, walls and edges keeps water out; vents let the attic breathe.
- Tear-off of old layers. A roof that already has two layers usually has to be torn off; ask your roofer. Tear-off also shows whether any deck boards need replacing.
Insurer discounts: some insurers lower premiums for Class 4 shingles or a FORTIFIED roof. Call your own insurer before you choose and ask what would qualify; no discount is automatic.
Rough Numbers for Shingle Roof Replacement
Treat these as starting points, not prices. Per-square-foot figures refer to roof surface, which runs larger than floor area.
| Cost row | Figure | Source (year) |
|---|---|---|
| Davenport asphalt shingles, installed, per sq ft | about $4–$7 | HomeBlue, 2024 |
| Iowa re-roof, average | about $6,160 (range $4,794–$15,779) | This Old House, 2026 |
| Iowa architectural shingles, per sq ft | about $5.95 | RoofObservations, 2026 |
| Iowa exposed-fastener steel, per sq ft | about $8.00 | RoofObservations, 2026 |
| Iowa standing-seam steel, per sq ft | about $12.40 | RoofObservations, 2026 |
The site's calculator uses $4.50 to $7.25 per square foot for shingles. Class 4 shingles, steep pitches, extra layers and rotten decking all push a real quote toward the top of that range or past it.
Inspection, Estimate, Install
- Reach out. Fill in the form or call (563) 555-0188, and your details go to one independent roofer.
- Roof and attic check. The roofer looks for curling, granule loss, soft decking, flashing gaps and signs of past ice dams.
- Written price. It should list the shingle line, underlayment, ice barrier, flashing, vents, tear-off, deck repair rates and warranties.
- City permit. Inside Davenport, roofing needs a building permit from Public Works. The roofer usually pulls it. Outside city limits in unincorporated Scott County, Iowa, a home roof permit costs $50 through Planning & Development, (563) 326-8643.
- Tear-off, install, inspection. Old layers come off, the deck is repaired, shingles go on and the permit closes.
Why the Process Matters
A few checks protect you before you sign. In Davenport, a roofer needs a City of Davenport contractor license to do or supervise the work; ask whose name it's under. Statewide, Iowa has no roofing license, but contractors who earn $2,000 or more a year from construction register under Iowa Code chapter 91C, and the state line at 515-242-5871 can confirm a registration.
Also ask for current proof of insurance, both warranties on paper, an itemized contract and local references. If insurance is paying, Iowa bars roofers from promising to rebate your deductible or negotiating your claim.
Quick Answers
Do I have to buy Class 4 shingles in Davenport?
No. Impact-resistant shingles are a choice, not something the City or the state requires. They cost more up front, and some insurers give a premium credit for them. Get the price of both kinds from the roofer, then ask your insurer what, if anything, the upgrade would save you.
Can new shingles go right over the old ones?
Not always. A roof that already has two layers usually has to be torn off; ask your roofer. Even with one layer, many owners pick a tear-off, since it exposes the deck and lets the ice barrier go straight onto the wood.
Who pulls the permit for a shingle re-roof?
Usually the roofer, under a City contractor license. If you live in the single-family home you own, the City lets you pull your own permit, but then scheduling every inspection falls to you. Questions go to Davenport Public Works at 563-326-7745.
