Why multifamily is a different project than a house
On a single building you own outright, siding is mostly a product-and-color decision. On a shared or income property, three things change the job:
- The risk is shared, and so is the blame. A condo treasurer or asset manager is spending other people’s money on a six-figure project. The decision has to be defensible — which means the bids have to be comparable and the plan has to be written down.
- People live there the whole time. This is occupied-building work. The plan has to move around residents, parking, and balconies, not pretend the building is empty.
- The money rarely sits ready. Most associations don’t have the full cost in reserves, so funding is part of the project from day one (more below — and it’s more manageable than it sounds).
That’s the reframe that organizes everything else on this page.
How do we know the building actually needs new siding?
Look for water getting behind the wall, not just cosmetic wear. The clearest signals: swelling, soft, or delaminating composite board; cracked or buckled vinyl; cracking and dark staining on stucco; hail dents or cracked panels after a storm; interior leaks, soft trim, or mold complaints; and rising work orders clustered on a few elevations. On KC buildings, the south and west faces that take the most sun, wind-driven rain, and hail usually fail first.
A few cosmetic problems mean repair. Widespread, moisture- or hail-driven failure across multiple elevations — especially on 1980s–90s LP/Masonite hardboard or problem-era stucco — usually means replacement, because patching a failing wall just resets the same clock.
| What you see | Likely meaning | Typical path |
|---|---|---|
| Isolated cracked panels, fading | Age / cosmetic | Repair or paint |
| Swelling, soft composite board on several walls | Hardboard failure | Plan replacement |
| Dents, bruising, cracked panels after a storm | Hail damage | Document, scope an insurance claim |
| Cracks + staining on stucco, interior moisture | Envelope/flashing failure | Investigate, likely replace |
| Caulk failing at every window, soft sheathing found | WRB/flashing failure | Replace + correct the details |
Which material holds up best for KC multifamily?
Because hail is Kansas City’s defining exterior threat, impact resistance leads the decision. The four practical choices:
| Material | Hail / impact | Lifespan | Best fit |
|---|---|---|---|
| Engineered wood (LP SmartSide) | Strong — warranted to 1.75″ hail | 40–50 yr | Best all-around value for big reclads; lighter, longer boards mean fewer seams |
| Steel | Product-specific evidence required | 50+ yr | Can dent; compare exact product and warranty |
| Fiber cement (James Hardie HZ5) | Moderate — impact performance is product-specific | 50+ yr | Fire-rated premium for attached buildings; specify HZ5, not HZ10 |
| Vinyl | Weak — brittle in cold and hail | 20–30 yr | Budget/value housing |
Stucco/EIFS is usually a replace-with-care case in KC because of its moisture-failure history. For the full breakdown across freeze-thaw, fire, and cost, see best siding for Kansas City hail. Material is only half the decision, though — what goes behind the panel is what determines whether you do this again.
The wall system behind the siding
Everything behind the siding is what keeps water out: the water-resistive barrier (WRB), flashing at windows, doors, and roof-wall intersections, kick-out flashing, trim transitions, and the sheathing itself. Residents judge the cladding; water judges the detailing. KC’s hardboard and stucco failures were overwhelmingly water getting in behind the wall — so a replacement that re-clads without correcting those details just reschedules the leak.
KC code names these details. Under the IBC edition Kansas City, MO and the Johnson County cities have adopted, a continuous WRB is required behind cladding, flashing has to be applied to shed water, and inspectors check the WRB and flashing before the new siding covers the wall. The crew you choose should treat that inspection as the point, not a hurdle.
How do associations and owners pay for it?
Most associations cover a project this size with a mix of replacement reserves, a special assessment, and an association loan; apartment owners fund it from capital budgets or a refinance. Here’s the KC reality, said plainly: neither Missouri nor Kansas requires associations to fund reserves, so a lot of communities reach the siding bill before the money’s saved. That’s normal here — it just means the funding plan is part of the project, not a surprise.
The three levers, and how boards usually combine them:
- Reserves — use what’s there; rarely covers a full re-side alone.
- Special assessment — the most common gap-filler. In Kansas a board can propose one following a short notice-and-comment step; in Missouri the rules live in your recorded declaration. Either way, an assessment owners can absorb (sometimes phased over a season or two) is easier to pass than a single large hit.
- Association loan — spreads the cost over years so no single owner takes the whole bill at once; your governing documents control whether the board can borrow.
The practical move is to map the funding before bids go out, so you’re choosing a scope you can pay for. Full detail: how associations pay for siding — reserves vs. assessment vs. loan. (This is general information, not legal or financial advice — confirm specifics against your association’s governing documents and attorney.)
Can we re-side without moving residents out?
Residents may be able to remain when the phase plan maintains safe access, essential services, and separation from the work. Confirm parking, balcony restrictions, routes, and advance notices by building. Include a decision process for hidden damage, utility work, or another condition that could require different arrangements. Full playbook: re-siding an occupied building.
What a multifamily siding bid needs to include
This is where boards lose money: a “low” bid that left out tear-off, rot repair, or flashing isn’t cheaper — it’s just less complete, and the difference shows up as a change order later. Every bid you collect should spell out:
- Material and profile (and the exact product line — e.g., LP SmartSide lap, James Hardie HZ5)
- Full tear-off and disposal
- Sheathing and rot-repair allowance (the hidden rot is almost always there)
- Water-resistive barrier
- Flashing — windows, doors, penetrations, and kick-out flashing
- Trim and accessories
- Access equipment and staging
- Resident-disruption / communication plan
- Warranty terms — material and workmanship, stated separately
- Clearly separated options for phasing
When every vendor bids that same list, the numbers finally mean something. We can help you build it: what a real multifamily siding bid must include and the Replacement Scope Map.
The planning path, start to finish
- Identify the building — type, number of buildings, current siding and era, and the specific concern (hail, leaks, rot, swelling board, failed stucco).
- Map risk and access — priority elevations, water/hail-risk areas, sheathing unknowns, how work moves around residents.
- Read the wall, not just the panel — WRB and flashing condition, and what code requires when you re-side.
- Choose a path — repair, phased, or full replacement, each with a funding mechanism.
- Fund it — reserves, assessment, loan, or a multi-year plan.
- Build a comparable bid scope so every vendor bids the same project.
- Approve, then execute on an occupied building with a communication plan.
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.
