A homeowner's guide to siding a house in Colorado.

01

Why Colorado is harder on siding than other markets.

If you've ever looked at a manufacturer's brochure that says "30-year lifespan" and then looked at your neighbor's vinyl that's already faded and cracked at 12 years, you've found the gap between national specs and Colorado reality. There are six things in our climate that age siding faster than the spec sheets assume.

Hail. The Front Range sits inside one of the worst hail corridors in the country. Hail does different things to different materials: it cracks vinyl, chips and gouges fiber cement, dents soft cedar, and tears panels off the wall when it comes in sideways. A lot of the damage sits above eye-level on the second story, where ground-level inspections miss it entirely. We've walked roofs after storms where the homeowner thought their siding was fine until we put a ladder up.

UV intensity at altitude. The same sun that gives Colorado its bluebird skies hits siding harder than it does at sea level, because there's less atmosphere between the panel and the sun. South and west elevations age faster than north and east on the same house, vinyl gets brittle on the warmer sides, and painted surfaces chalk unevenly. A house's south wall can look five years older than its north wall after a decade.

Temperature swings. It's normal for a Front Range house to see a 50-degree swing in a single day. Every material expands and contracts constantly, which is why installation gap allowances and the rainscreen behind fiber cement actually matter. Skip those details on the install and the panels warp, the seams crack, and the fasteners fatigue out of the wall in fewer than ten years.

Wind. Chinook winds routinely hit 60 to 80 mph along the foothills. Improperly nailed vinyl gets peeled off houses every spring. Properly nailed vinyl, with the right spacing and the right locking detail at the panel edges, shrugs the same wind off without a problem. Installation matters more than material here.

Dry winters. Colorado winters are dry, which is hard on wood-based materials. Real cedar checks and splits faster here than in wetter climates. Engineered wood was developed in part because real wood couldn't reliably handle this kind of climate.

Snow and ice loading. Where a roof meets a wall, snow piles up, melts, and refreezes against the siding course directly below the roof line. Without proper kickout flashing and a real drainage plane behind the cladding, those courses get pushed loose and eventually start letting water into the wall.

The thing nobody tells you in the manufacturer brochure is that how it's installed matters more on the Front Range than almost anywhere else. The difference between siding that lasts thirty years and siding that needs work in ten is almost entirely workmanship, not material brand.

02

The four materials, and which one fits your house.

There are four siding materials we install across the Front Range, and the right one for your house depends on three things: what's there now, what your HOA allows, and how long you plan to stay. There's no single best material. Anyone telling you there is is selling whatever they're certified to install.

Vinyl

Lifespan: 20-30 years · Cost: $$ · Maintenance: low

Vinyl is the most-installed siding in the country for good reason. It's affordable, it never needs repainting, and the newer thick-grade product handles Colorado UV and temperature swings far better than the cheap stuff did a decade ago. The color and profile options have caught up too, with board-and-batten, shake, and modern dark-color lines that used to require wood. Hail can crack it, but individual panels are easy to swap. We'd point most Front Range homeowners here as a first option, especially if your HOA allows vinyl and you don't want repainting on the maintenance list.

Where vinyl falls short: the very cheapest builder-grade vinyl is genuinely bad and ages quickly. Don't compare bids on the word "vinyl" alone, ask each contractor what brand and what grade.

Engineered Wood (LP SmartSide)

Lifespan: 30-50 years · Cost: $$ · Maintenance: paint every 7-10 yrs

Engineered wood gives you the look of real wood without most of the problems. It's factory-primed, dimensionally stable, and treated against rot and insects. It's lighter than fiber cement, which means faster installation and lower labor cost, and we're seeing it more and more on mountain-style and craftsman-style new builds across the Front Range. The big advantage for a lot of homeowners is that it accepts paint beautifully and holds color long enough that the repaint cycle is a real interval, not a yearly chore.

Where engineered wood falls short: you do have to paint it, and if you let the paint fail completely the substrate is more vulnerable than fiber cement is.

Fiber Cement (HardiePlank)

Lifespan: 40-50 years · Cost: $$$ · Maintenance: paint every 10-15 yrs

If you've seen a high-end remodel in Colorado in the last decade, there's a good chance it's wearing HardiePlank. It looks like real wood from the curb, holds paint for 10 to 15 years between repaints, and stays dimensionally stable through both fire and Front Range temperature swings. It's heavier and much more labor to install than vinyl, so the structural detail under it matters and the install crew has to know what they're doing. For a house you plan to keep more than ten years, this is the material that pays you back over the long run.

Where fiber cement falls short: the upfront cost is real. We won't push it if your budget doesn't reach there, because vinyl or engineered wood in the right grade can be the right answer for a house you're planning to sell in five years.

Real Cedar Shake and Shingle

Lifespan: 20-30 years in CO · Cost: $$$ · Maintenance: heavy

Real cedar is beautiful, but Colorado is harder on it than almost any other climate. UV dries it out, hail bruises it, and most insurance carriers have started excluding or capping cedar replacement coverage. We will install it when an HOA requires it, but in almost every other case we'll walk you through the synthetic alternatives first, because they look nearly identical from the curb and last decades longer.

Where cedar falls short: almost everywhere if you don't actively want it. Cedar is a labor-of-love material, not a default choice.

How to pick

If you're undecided, the three questions to answer first are how long you plan to stay in the house, what your HOA allows, and what your budget tolerance is. Five years and tight budget pushes toward vinyl. Ten years and a remodel mindset pushes toward fiber cement. In between is where engineered wood often wins, because it gets you the look of fiber cement at a vinyl-adjacent price.

03

How to read a siding bid, line by line.

Getting three quotes for new siding usually means getting three numbers that are fifteen to twenty thousand dollars apart from each other. That spread is real, and some of it is just differences in material and labor cost between contractors. The rest of it is usually a low bid that left out the things that go wrong mid-job, so the change orders show up later. Here are the eight lines that move a siding bid the most, and what to look for in your own quotes.

Material grade

The word "vinyl" covers a 3x price range from builder-grade to thick-profile premium. Same for fiber cement. Two contractors quoting "Hardie" can be quoting products that don't perform alike at all in Colorado. Always ask for the brand AND the product line AND the thickness or grade.

Sheathing and rot allowance

This is the single biggest hidden line item, and it's where most low bids hide. The sheathing is the structural panel that sits under your old siding. We cannot see it until the old siding comes off. Some percentage of Colorado homes have areas of soft sheathing, especially under windows and at kickout flashings. A real bid quotes a per-sheet unit price for replacement sheathing UPFRONT, so when we find some, you already know what it costs per square foot. A bid that doesn't mention it is going to surprise you with a change order at retail prices.

Tear-off and disposal

Somebody pays the dump fees on a couple tons of old vinyl or cedar. That somebody should be the contractor, and the cost should be on the bid. If a bid doesn't itemize tear-off and disposal, ask where it lives.

Flashing details

Kickout flashing at the roof line, window head flashing, J-channel, corner boards, drip cap above doors. These are the parts of a siding job that decide whether your wall leaks five years from now. They're also where cheaper bids cut corners that aren't visible to a homeowner standing on the lawn. Ask each bidder how they handle kickout flashing specifically, because that single detail is the most common source of leaks in the first ten years.

Wrap and rainscreen

The drainage plane that sits behind the cladding is invisible the day the job is done and decides how the wall ages over the next twenty years. Tyvek is the most common wrap. A real fiber cement install also has a ventilated rainscreen detail that lets the wall breathe. A bid that doesn't break these out by name probably isn't installing them the way Colorado climate actually needs.

Tear-out and replacement of trim

Window trim, soffit trim, fascia, frieze board. These often need partial or full replacement during a re-side, and a low bid often leaves "as needed" instead of pricing it. Ask each bidder to quote trim replacement on a unit-price basis.

Crew and supervision

Some contractors quote and sign, then subcontract the install to a crew they've never worked with. Others run an in-house crew. Both can produce good work, but you should know which one before the truck pulls up. Ask each bidder who is doing the install and who is on site every day.

Permits, HOA approval, dumpster placement, port-a-potty

Front Range cities mostly require permits for full siding replacement. Most HOAs require color and material approval. Both of these take time and money, and a bid that doesn't include them is asking you to handle them yourself. Worth confirming who is responsible for each.

The apples-to-apples view

Ask each contractor to break the bid out into these same eight lines. The lowest bid almost always loses the comparison once you can see what's missing. We don't usually win the bidding war on raw price. We try to win it by being the bid you can trust, with every line itemized so you can see what's in it and what's not.

04

The change-order ambush: what's behind the siding.

This is the question every homeowner is rightly afraid of, because most contractors don't say a word about it until they're elbow-deep in the wall and the conversation has shifted from "what's this going to cost" to "what choice do I have." Nobody can actually see what's behind the old siding until it comes off, but the contract you sign can absolutely lay out what happens when surprises show up.

What we usually find

Most Front Range homes have at least a small amount of sheathing rot, usually around windows and where roofs meet walls. The catastrophic cases are rare. The typical case is a few square feet of soft OSB under a window with a failed kickout flashing, easy to replace at the same time as the re-side, but it would be a real problem if it kept going for another five years.

What the contract should say

A good contract quotes a per-sheet unit price for replacement sheathing BEFORE the job starts. You know what the worst case costs per sheet. When the install crew finds soft spots, they stop, photograph the area with a tape measure in frame for scale, send you a count, and wait for approval before they replace it. If you want a second opinion before approving, the contract should let you take the time.

What the contract should not say

It should not say "rot repair priced as needed" or "additional work at prevailing rates." Both of those phrases mean "we'll charge you what we want when we find something," which is how a $24,000 job becomes a $34,000 job mid-tear-off.

What we do

We quote a per-sheet sheathing price upfront on every bid, we photograph and count any rot we find before we move forward, and if we tear off and find no rot the unit price applies to nothing and you pay zero for it. The contract you sign with us is the contract that gets executed, not a starting point.

05

Hail, insurance, and what your carrier actually owes.

If hail is why you're reading this, the conversation with your insurance carrier is going to follow a pattern that's roughly the same across most policies, with a few twists that are worth knowing about before you call. The rules are inconsistent across carriers and even across individual adjusters, but the framework is consistent.

What's usually covered

Functional damage from a covered weather event. If hail cracked the vinyl, punctured the fiber cement, or tore a panel off the wall, that's almost always a covered loss. Wind damage is also typically covered as long as the wind event meets the policy's threshold.

The "cosmetic only" exclusion

More and more carriers are writing this into policies, particularly for cedar and older vinyl. The carrier's position is that small dents or chips don't affect the function of the wall, so they won't pay to replace it. You can sometimes get that reversed by walking the elevation with the adjuster and showing damage they missed from the ground. Not always, but often enough that it's worth the appointment.

Matching law

Colorado matching law sometimes requires the carrier to pay for full replacement when one elevation is damaged and the original product is no longer made in your color. The rules are case-by-case and the carrier won't volunteer this, so it's worth raising during the adjustment and bringing documentation that the panel is discontinued.

Deductible

Your deductible is whatever your policy says it is. No Colorado contractor can legally pay it, waive it, rebate it, or absorb any part of it. CRS 6-22-105 makes that illegal for roofing and exterior contractors, and accepting that offer can also invalidate your claim. Any contractor offering to "cover your deductible" is breaking the law and putting your claim at risk.

ACV vs. RCV

Most policies pay actual cash value (the depreciated value) up front and release the recoverable depreciation once the work is complete and documented. The depreciation release is where homeowners often get stuck, because the carrier needs specific paperwork to release it. We assemble that paperwork as part of the close-out so the money you're owed actually shows up.

What we do, exactly

You file the claim with your carrier, because Colorado law requires the homeowner to be the one to file. We document the damage with photos, measurements, and a written scope you can attach to the claim. When the adjuster comes out, we're there to walk them through what we found. We do not act as a public adjuster and we do not decide what your carrier owes you, because that part stays between you and them. What we do is make sure the damage gets seen and counted accurately.

06

The six tests for picking the right contractor.

Right after a storm you'll have business cards in your door, voicemails on your phone, and trucks rolling through the cul-de-sac with plates from three states away. Some of those companies are real, and a lot of them won't be reachable by March. These are the six questions to ask any contractor who knocks on your door this week, with the answers a real local one should give.

1. Where is your physical office?

   A real address with a real building and a real sign that you can drive past before you sign anything. Not a PO box, not "Denver, CO" with no street, not a virtual office. The contractors who fail this test almost never recover from it.

2. What's your Colorado contractor license number?

   A 303 area code is not a license. "We're local" without a verifiable license number is just a sentence. Colorado licenses are searchable through the state. Real contractors list the number on every contract, every invoice, and often the truck.

3. Can I see your Google review history?

   Look at the dates, not just the star count. Storm chasers spin up new review profiles. A real contractor has reviews from last year and the year before. If every review is from the last 30 days, the company is one storm old.

4. Who answers the phone in February?

   The real test is whether the company you're handing tens of thousands of dollars to will still take your call when there's no work to chase. Ask who handles warranty calls in the off-season. Real contractors have a real answer.

5. Who's actually swinging the hammer?

   Some contractors quote and sign, then subcontract the install to a crew they've never worked with. Ask whether the people doing the install are in-house or subbed. Both can produce good work, but you should know which one before the truck pulls up.

6. How do you talk about insurance?

   A contractor who says "we'll get you a free roof" or "we'll cover your deductible" is breaking Colorado law and probably won't be around when your claim falls apart. A contractor who says "we document the damage, you file the claim, we sit in at the adjuster meeting" is following the law and is the partner you want.

We pass these tests because Eli and Michele have lived here for years and the company is built around being here when the work is done. Plenty of other good Colorado contractors do too. The point isn't that we're the only honest shop in town, it's that the contractors who fail this checklist should be a hard no, and a lot of them are in your neighborhood this week.

07

HOA approval, permits, and the timeline reality.

A re-side in Colorado is rarely just an install. It's an install plus a permit plus HOA approval plus material lead time plus weather windows. Each of those moves the start date around, and the contractors who quote you a "two weeks from now" start date are usually telling you the install duration, not the calendar timeline.

HOA approval

Almost every HOA in the Front Range requires written approval for color and material on exterior changes. Some require samples submitted, some require neighbor sign-off, and some require an architectural review committee meeting. Submission to approval can take 30 days. We handle the package and the submission for you, but the approval timeline belongs to the HOA, not us.

Permits

Most Front Range municipalities require a permit for full siding replacement. Some don't, for like-for-like material swaps. Pulling the permit is on us, and the city's turnaround can be anywhere from a few days to a few weeks.

Material lead time

Vinyl is usually in stock within a week. Fiber cement and engineered wood can run two to four weeks depending on color and supplier. Specialty colors and trim profiles can push longer. Once you've picked colors, we order, and the install date follows the material delivery.

Install duration

A typical residential re-side runs three to seven days on site once the crew starts. Bigger or more complex houses can run two weeks. Cold weather slows things down for fiber cement specifically because the panels become harder to cut cleanly. We don't install in snowstorms.

What this means for your calendar

If you call us this week and want to be done before Thanksgiving, that's almost always achievable. If you call in March and want to be done before your daughter's spring wedding in May, also achievable. If you want to start the install tomorrow, that's almost never the right answer because the HOA, permit, and material steps need to happen first, and skipping them risks the whole project.

08

Color choice without color regret.

Picking a color from a two-inch chip under the showroom lights is the single most common source of color regret in re-siding. The same shade reads completely differently on a house than it does on a sample card, because the scale is different, the light is different, and the surrounding trim and roof colors all push the perception.

What we do

We bring real physical samples to your house, not a digital swatch on a tablet. We hold them up against your trim, your roof, your front door, and the houses on either side of yours. We look at them in your actual morning light, your actual afternoon light, and at dusk. Then we narrow to two or three candidates and let you live with them for a few days before you commit.

What you should look at

The biggest things that drive color regret are undertones (your gray might be reading green or blue), saturation (a deep color is going to look much darker on the whole house than on the chip), and contrast with your trim. A color that pops on a swatch can feel muddy on a whole house.

Resale considerations

If you might sell in the next five years, lean conservative on body color and let the front door and trim do the personality work. Off-whites, warm grays, taupes, and soft greens have the broadest resale appeal across the Front Range. Bold body colors (deep navy, dark green, saturated red) read beautifully when they work but narrow the buyer pool when they don't.

HOA considerations

Most HOAs publish an approved palette. Even within the approved palette, what your HOA approves and what looks right on your specific house may not be the same. We've had homeowners pick the right hex code off the HOA list and end up with a wall they didn't like because the sample they saw was on a different house. Bringing real samples to your house is the only way to avoid this.

09

After the install: warranties, maintenance, and when to call back.

Two warranties cover the work we do. They come from different parties and cover different things, and most of the calls we field five or ten years after a job involve a homeowner trying to figure out which warranty applies to what they're seeing.

The manufacturer warranty

Comes from the company that made the panels: James Hardie, LP SmartSide, CertainTeed, whichever brand we installed. It covers defects in the material itself, like color failure, premature cracking that isn't weather-related, or structural delamination. We register every install in your name with the manufacturer when the job is done, so the warranty transfers correctly if you sell the house.

The COPA Promise: workmanship warranty

Comes from us, and it covers anything that fails because of how we installed it rather than how the panel is made. Flashing detail at the windows, kickout flashing at the roof line, ventilation behind the cladding, the moisture barrier behind it all, those are the things that fail when a job is rushed. Any of that is on us if it goes wrong. In the first ten years, this is the warranty that actually ends up mattering, because real material failures from defects are rare and install failures from rushed crews are unfortunately common.

Maintenance the realistic version

Vinyl: rinse it once a year, look for cracked panels after storms, that's about it. Repaint never.

Engineered wood: rinse it once a year, repaint every seven to ten years, check the caulk lines at trim joints annually.

Fiber cement: rinse it once a year, repaint every ten to fifteen years, check the caulk lines and the kickout flashings annually.

Real cedar: annual inspection, stain or oil every two to four years, replace failed shakes as you find them.

When to call us back

If you notice a panel that's cracked, peeled, popped loose, or visibly damaged after a storm, call. If you see staining inside the house on an exterior wall, call sooner. If a kickout flashing or a window head flashing starts shedding water in the wrong direction, call as soon as you notice. The COPA Promise covers these, and the earlier we catch them the smaller the repair.
