Siding in Des Moines

What's different about siding in Des Moines

Des Moines siding has to handle one of the widest weather spans of any major U.S. metro. Winters bring stretches of subzero cold and freeze-thaw cycling that punishes brittle materials; summers are hot and humid; and spring and summer deliver hail and severe thunderstorms on a regular schedule. The August 2020 derecho — a long-track straight-line wind event with gusts well over hurricane force — drove home that central Iowa also faces a wind peril most homeowners never plan for. A Des Moines wall assembly has to flex through all of it.

The housing stock spans more than a century. Older Des Moines neighborhoods — Sherman Hill, the East Village fringe, Beaverdale, the South Side — carry homes from the early 1900s through the postwar decades, many with original wood siding, board sheathing, and dated flashing. The suburban ring — West Des Moines, Ankeny, Urbandale, Waukee — has grown fast over the last twenty years and is largely brick-and-vinyl. The two worlds make for very different siding projects: restoration and moisture remediation in the core, storm-damage repair and upgrade re-sides on newer subdivision vinyl.

Freeze-thaw is the quiet factor that shapes material choice. Iowa winters drive water into any gap in a wall and then expand it. That rewards siding that resists cracking and moisture intrusion and a wall built with sound flashing and a continuous weather-resistive barrier. Fiber cement and engineered wood both perform well through Iowa's temperature swings; vinyl is the volume choice and works fine when installed with proper expansion allowance. Whatever the material, detailing is what carries a Des Moines wall through forty below and ninety-five above.

Des Moines permits and the suburban patchwork

A residential re-side in Des Moines requires a permit, and the permit is where the city confirms the new wall assembly meets the weather-resistance and wind provisions of the code currently enforced.

Inside the City of Des Moines, residential re-siding is permitted through the Permit and Development Center, part of Development Services. A like-for-like replacement is a routine permit and does not require engineered plans, but the contractor must describe the scope, and the new assembly is expected to include a code-compliant weather-resistive barrier and proper flashing. Work that alters framing or replaces significant sheathing gets a closer review. The permit must be active for inspection, and an unpermitted re-side commonly surfaces as a problem at resale.

The Des Moines metro is a patchwork of independent cities, and that matters for permits. West Des Moines, Ankeny, Urbandale, Waukee, Clive, Johnston, and Altoona each run their own building departments with their own forms, fees, and inspectors. A permit pulled in Des Moines does not apply in West Des Moines, and vice versa. Because the suburban ring is where most of the metro's recent housing growth sits, plenty of homeowners who think of themselves as 'Des Moines' actually permit through a suburb. Confirm your jurisdiction before any siding comes off, and ask the contractor to name it on the contract.

• Iowa contractor registration
  Construction contractors performing work in Iowa must register with Iowa Workforce Development. Verify the registration number, and confirm general liability and workers' compensation coverage, before you sign — storm-chasing crews that follow Iowa hail and derecho events frequently lack one or more of these.
• Wind-resistance fastening after the derecho
  The 2020 derecho put a spotlight on fastening. Des Moines enforces a modern edition of the International Residential Code, and the fastening schedule for new siding is what determines how a wall holds in a straight-line wind event. Ask your contractor to confirm the assembly meets the wind provisions for central Iowa.
• Separate suburban jurisdictions
  West Des Moines, Ankeny, Urbandale, Waukee, Clive, Johnston, and Altoona permit independently of Des Moines. A Des Moines permit does not carry over. Confirm your jurisdiction first, because the process and inspector differ between cities.

Typical siding replacement cost in Des Moines

Des Moines siding pricing sits near the national average — central Iowa labor is competitive — but a major hail event or another derecho can tighten contractor availability and push quotes up sharply for a season. Vinyl dominates the suburban market; fiber cement and engineered wood are common on storm rebuilds and older-home re-sides. Treat these as directional ranges, not bids.

Ranges synthesized from 2025–2026 central Iowa siding market surveys and Des Moines-area contractor pricing. Real quotes vary with wall height, access, sheathing condition, fastening schedule, and post-storm demand.

Neighborhoods where siding looks different

A re-side in a new Waukee subdivision is not the same project as a restoration in Sherman Hill. A few Des Moines specifics worth knowing before you bid:

• Sherman Hill
  Des Moines's premier historic district, dense with restored Victorian and early-1900s homes. Changing visible siding material or profile here can require review through the local historic preservation process. In-kind restoration is the usual path and is specialty work.
• Beaverdale
  Known for its 1920s and 1930s brick "Beaverdale brick" Tudors and bungalows, but plenty of homes here carry wood or wood-and-brick exteriors. Re-sides often uncover dated flashing, and many owners move to fiber cement or engineered wood to keep the look with less upkeep.
• South Side and East Side
  Older working-class neighborhoods with a wide mix of early-20th-century and postwar homes, much of it on original wood or aging vinyl. Tear-offs here regularly reveal sheathing and flashing issues that belong in the bid as a contingency.
• West Des Moines, Ankeny, Waukee, and Urbandale
  The fast-growing suburban ring, dominated by brick-and-vinyl subdivision homes from the last twenty-plus years. Work here is mostly storm-damage repair and upgrade re-sides on builder-grade vinyl. Confirm which suburb permits your address, because the process differs from Des Moines proper.

Des Moines storm events siding contractors still reference

Central Iowa's siding work is shaped by straight-line wind, hail, and severe thunderstorms. The events below are the metro-specific ones local crews still talk about.

• 2020
  August 2020 Midwest derecho

  A long-track straight-line wind event that crossed Iowa on August 10, 2020 with gusts well over 100 mph in places. It caused billions in damage statewide, downed trees and power lines across the Des Moines metro, and stripped siding, soffit, and fascia from homes. It is the storm that reframed wind resistance as a central-Iowa concern, not just a Plains one.
• 2022
  March 2022 tornado outbreak

  A severe-weather outbreak in early March 2022 produced damaging tornadoes south of the Des Moines metro and reminded the region that Iowa's severe season can start early. It drove a wave of exterior-damage claims across the southern suburbs.
• 2023
  Summer 2023 hail season

  A series of severe-thunderstorm days through the summer of 2023 brought damaging hail across Polk and Dallas counties, driving siding and exterior claims across the metro. Hail seasons like this are the routine background pressure on the Des Moines siding market.

Des Moines siding FAQ

• Do I need a permit to replace siding in Des Moines?
  Yes. The City of Des Moines Permit and Development Center requires a building permit for a residential re-side. A like-for-like replacement does not need engineered plans, but the permit must be active for inspection. Skipping it usually leaves no inspection record, which can complicate resale and future insurance claims.
• I live in West Des Moines or Ankeny — does the Des Moines permit apply?
  No. West Des Moines, Ankeny, Urbandale, Waukee, Clive, Johnston, and Altoona each run their own building departments with their own forms and inspectors. A permit pulled in Des Moines does not carry over. Confirm which suburb your address falls in before work starts, and have the contractor name the jurisdiction on the contract.
• What siding handles Iowa winters and summers best?
  Des Moines siding has to survive both subzero freeze-thaw cycling and hot humid summers. Fiber cement and engineered wood both hold up well across that range and resist hail better than standard vinyl. Vinyl is the budget choice and performs fine when installed with proper expansion allowance. In every case, flashing and a continuous weather-resistive barrier are what carry the wall through the temperature swings.
• Will my insurance cover siding damage from the derecho or a hailstorm?
  Often, yes, if the policy covers wind and hail and the damage is documented. Get an adjuster inspection, take dated photos of cracked or missing panels, and keep your contractor's scope aligned with the adjuster's estimate. Statewide claim-handling rules are covered on the Iowa siding guide; this page covers the local repair picture.
• How do I avoid storm-chasers after an Iowa hail or wind event?
  Hail and derecho events draw out-of-state crews. Verify the contractor is registered with Iowa Workforce Development, confirm general liability and workers' compensation coverage, insist on a physical local address, and pay in stages rather than in full upfront. A contractor pushing you to sign an insurance assignment on the spot is a warning sign.
• My Des Moines home is from the 1910s — what should I expect?
  Expect the tear-off to reveal things the bid could not see: dated or missing flashing, original board sheathing, and sometimes rot at the base of the wall. Older homes in Sherman Hill, Beaverdale, and the East and South Sides routinely need flashing and sheathing correction before new siding goes on. Build a contingency into your budget and ask how change orders for hidden damage are handled.
• Is vinyl a bad choice after the derecho?
  Vinyl is the most common siding in the Des Moines suburbs and a reasonable budget option, but it is more easily damaged by hail and straight-line wind than fiber cement or engineered wood. If wind resilience is a priority, the heavier materials are worth considering. Either way, the fastening schedule matters as much as the panel — ask your contractor to install to central Iowa wind provisions.
