Why siding is an NOI and asset-value decision
Because deferred siding compounds three ways. It depresses rents and turnover on a tired-looking building, it leaves an aging wall for the next hailstorm to total, and it surfaces as a capital-needs flag when you refinance or sell. A planned replacement with impact-resistant cladding does the reverse — it protects NOI, lowers the next claim, and removes a re-trade point from the deal.
You’re not picking a product; you’re allocating capital. The questions are whether to replace now or defer, what per-unit number to budget, which material lowers lifecycle cost and future insurance exposure, and how to execute without bleeding occupancy. The owners who plan the replacement control the cost; the ones who wait let a storm set the timeline.
How to model siding cost per unit
Model it per unit and per building, not as one lump sum. The per-unit number turns on material, building height and access, how much hidden rot the tear-off reveals, and whether trim and flashing are bundled or treated as alternates. A defined scope is what produces a credible per-unit figure — and what keeps a “low bid” from ballooning once the old siding comes off.
| Cost driver | Why it moves the per-unit number | What to do about it |
|---|---|---|
| Material choice | Hail-durable products cost more upfront, less in claims | Model lifecycle cost, not just install cost |
| Building height & access | Taller or garden-style staging changes labor | Price access equipment as a line item |
| Hidden rot / sheathing | Almost always present in 1980s–90s stock | Require a priced rot allowance, not “TBD” |
| Trim, flashing, WRB | Often left out to lower the headline number | Itemize so bids compare line by line |
| Phasing | Spreads capital across budget years | Break out alternates by building |
We don’t publish a fixed per-unit price we can’t stand behind — the right move is a line-item scope that several vendors price the same way, so the per-unit number reflects your actual building.
Which siding lowers your future hail exposure
The impact-resistant ones. Radar has detected hail at or near Kansas City on 193 occasions, so for an owner the material choice is an insurability decision first. Engineered wood (LP SmartSide) is warranted against hail up to 1.75 inches, and steel siding needs product-specific evidence rather than a roofing classification.
| Material | Hail / impact | Owner case in KC |
|---|---|---|
| Engineered wood (LP SmartSide) | Strong — warranted to 1.75″ hail | Best value/hail balance; lighter, longer boards ease big reclads |
| Steel | Product-specific evidence required | Can dent; compare exact product and warranty |
| Fiber cement (James Hardie HZ5) | Moderate — impact performance is product-specific | Fire-rated premium for attached buildings; specify HZ5 |
Vinyl is lowest upfront but carries the highest recurring claim risk, and stucco/EIFS is often insurance-excluded. Note that Kansas City sits in James Hardie’s HZ5 climate zone — the cold-climate, freeze-thaw line — not the Southern HZ10, a spec a lot of out-of-town content gets wrong.

How to re-side without losing occupancy
Treat resident disruption as part of the scope. Occupied-building siding work touches parking, balconies, entrances, and noise for weeks, and uncontrolled, that turns into move-outs and bad reviews. A sequencing plan that works building by building, staging and parking management that preserves resident parking, advance notices on a published schedule, and a single resident channel keep the work moving without driving turnover. The vacancy risk owners fear is a logistics problem solved upfront. The full execution detail is in re-siding an occupied building and the resident communication & access plan.
How hail and your deductible change the owner math
A higher deductible means more of each claim is yours, which is exactly why impact-resistant cladding that avoids the claim pays back. Severe convective storms drove $54 billion in U.S. insured losses in 2024, and Kansas storm claims alone hit roughly $612 million — pushing rates up about 15% in 2025 and percentage-based wind/hail deductibles up with them.
Run the deductible math before the storm, not after. KC apartment and HOA master policies increasingly carry percentage-based wind/hail deductibles, so a claim on an aging vinyl wall can leave you covering a large share out of pocket — and EIFS/synthetic-stucco damage is frequently excluded or contested. Document any storm damage promptly, scope siding alongside the roof so it isn’t under-claimed, and weigh the upfront cost of impact-resistant material against the claims it prevents over the hold period.

How deferred siding shows up in a refinance or sale
As a capital-needs flag. A lender’s property-condition assessment or a buyer’s inspection will price aging or hail-damaged siding into the deal — as a reserve hold, a re-trade, or a lower number. Siding on 1980s–90s stock is a common line, especially after a hail event the prior owner didn’t address.
A documented, recent re-side does the reverse: it removes the flag, supports the valuation, and signals an asset that’s been run, not deferred. Owners who plan the re-side ahead of a refinance or sale convert a deal risk into a value story, and a defined scope gives you the documented per-unit basis to carry into the transaction.
Who does the work
Installations are performed by an established Kansas City–area siding contractor we vet for multifamily experience, manufacturer-correct installation, licensing and insurance. They hold a 5.0 Google rating from 100+ reviews. KC Multifamily Siding is the research and planning side. Before any contract you get the installer’s company name, license information, and warranty terms in writing.
Does a roofing impact rating establish siding performance?
No. UL 2218 scope covers prepared steep-slope roof coverings. Do not assign a roof result to every steel wall panel. Ask for the exact siding product, applicable test report, conditions and limitations. Cosmetic denting, finish damage, water entry, warranty coverage and insurance treatment are separate questions.
