6 Warning Signs You Need Roof Replacement in Des Moines

Your roof is your home's first line of defense against everything Iowa weather throws at it, and that's a lot. From brutal winter ice storms to summer hail, from heavy spring rains to baking summer sun, Des Moines roofs endure some of the most challenging conditions in the country.

But how do you know when your roof has reached the end of its lifespan? Most homeowners don't climb up on their roofs regularly (and you shouldn't—it's dangerous!), so problems can develop unnoticed until they become expensive emergencies.

At Midwest Seamless, we've been protecting Iowa homes since 1963. While we've recently expanded our services to include professional roofing installation and replacement in the Des Moines area, our decades of experience with Iowa's climate gives us unique insight into how weather affects every component of your home's exterior.

In this guide, we'll walk you through the six warning signs that indicate it's time for roof replacement. Recognizing these signs early can save you thousands of dollars in water damage and help you plan your investment on your timeline—not during an emergency.

Warning Sign #1: Your Roof Is 20+ Years Old

Let's start with the most straightforward indicator: age. Even if your roof looks fine from the ground, age alone can be reason enough to start planning for replacement.

Why Age Matters in Iowa's Climate

Standard asphalt shingles are typically rated for 20-25 years, but that's under ideal conditions. Iowa's climate is anything but ideal for roofing materials:

• Extreme temperature swings: We go from sub-zero winters to 95°F summers, causing constant expansion and contraction

• Freeze-thaw cycles: Water gets under shingles, freezes, expands, and causes progressive damage

• UV exposure: Iowa summers mean intense sun that breaks down asphalt and causes granule loss

• Severe weather: Hail, high winds, and heavy snow accelerate aging

Reality check for Des Moines roofs: In our climate, even quality shingles often show significant wear by year 18-20. By year 25, you're living on borrowed time.

How to Determine Your Roof's Age

If you're not the original owner, finding your roof's age requires some detective work:

• Check home inspection reports from when you purchased

• Look for permits filed with the city (roofing permits are public record)

• Ask previous owners or neighbors who've been around a while

• Contact your homeowners insurance company (they often have roof age on file)

• Look for manufacturer date stamps on shingles in your attic

What to do: If your roof is approaching 20 years old, schedule a professional inspection even if you don't see obvious problems. Proactive replacement on your schedule beats emergency replacement during a crisis.

Warning Sign #2: Shingles Are Curling, Cracking, or Missing

Walk around your house and look up at your roof. What do you see? Flat, uniform shingles? Or a surface that looks wavy, uneven, or patchy?

Visual Indicators of Shingle Failure

Curling shingles: Edges turn upward or the center "humps" up

• Caused by: Age, poor ventilation, moisture damage

• Why it matters: Curled shingles let water underneath, leading to leaks

• Iowa factor: Freeze-thaw cycles accelerate curling dramatically

Cracked shingles: Visible splits or breaks in the shingle surface

• Caused by: Wind damage, impact, age-related brittleness

• Why it matters: Cracks allow direct water penetration

• Iowa factor: Temperature extremes make aged shingles brittle and prone to cracking

Missing shingles: Gaps where shingles have blown off entirely

• Caused by: Wind, improper installation, failed adhesive

• Why it matters: Exposed underlayment won't protect your roof for long

• Iowa factor: Our spring and fall wind events regularly exceed 40-50 mph

Granule loss: Shingles look "bald" or you find granules in gutters

• Caused by: Age, hail damage, poor quality shingles

• Why it matters: Granules protect the asphalt from UV damage—once they're gone, deterioration accelerates rapidly

• Iowa factor: Hail is a major culprit in Central Iowa

The Progressive Nature of Shingle Damage

Here's what many homeowners don't realize: shingle problems spread. One damaged shingle compromises the ones around it. Water gets under edges, wind catches more easily, and the damage cascades.

If you're seeing widespread shingle problems across multiple sections of your roof, replacement is usually more cost-effective than ongoing repairs. A good rule of thumb: if more than 25-30% of your roof shows damage, it's replacement time.

Warning Sign #3: Interior Water Stains or Leaks

Sometimes the first sign of roof problems shows up inside your home, not outside.

What to Look For Inside Your Home

Ceiling stains: Brown or yellow discoloration on ceilings, especially near exterior walls

• Often circular or irregular shaped

• May appear after heavy rain or snow melt

• Can indicate active leaks even if ceiling feels dry

Attic moisture: Check your attic after rain or during humid periods

• Look for water stains on rafters or sheathing

• Check insulation for dampness or compression

• Watch for mold or mildew growth

• Notice musty odors

Wall stains near the roofline: Discoloration at the top of exterior walls

• Often indicates ice dam damage in winter

• Can signal flashing failures around roof edges

• May appear on interior or exterior walls

Peeling paint or wallpaper: Near ceilings or top-floor walls

• Moisture from roof leaks causes adhesive failure

• Often appears before visible water stains

• Common sign of chronic, slow leaks

Why Interior Signs Are Serious

By the time water damage appears inside your home, the problem has already progressed significantly. Water takes the path of least resistance, meaning visible leaks often indicate hidden damage to roof decking, insulation, and structural framing.

The cost of waiting: A small leak caught early might require minor repairs costing a few hundred dollars. That same leak left unaddressed can cause thousands in structural damage, mold remediation, and interior repairs—on top of the roof replacement you'll eventually need anyway.

Our recent blog post on whether homeowners insurance covers window replacement discusses when insurance might cover sudden damage versus gradual deterioration, similar principles apply to roofing.

Warning Sign #4: Sagging or Uneven Roof Lines

Stand back from your house and look at the roof line. Does it appear straight and true, or do you notice dips, sags, or uneven sections?

What Sagging Indicates

A sagging roof is a serious structural concern that goes beyond just the shingles:

Potential causes:

• Moisture damage to decking: Years of small leaks have rotted the plywood sheathing

• Structural issues: Rafters or trusses are failing

• Inadequate support: Original construction didn't account for Iowa's snow loads

• Age-related deterioration: The entire roof system is failing

Why this is urgent: A sagging roof can lead to catastrophic failure, especially under heavy snow load. This isn't just about leaks anymore—it's about structural safety.

Uneven Shingle Lines

Even if the overall roof line is straight, watch for:

• Wavy or humped appearance across shingle courses

• Inconsistent gaps between shingle rows

• "Tired" appearance where sections look compressed

These signs often indicate failing underlayment or moisture-damaged decking that needs replacement along with the shingles.

Professional inspection required: If you notice any sagging or structural concerns, schedule a professional roof inspection immediately. At Midwest Seamless, our experienced crews can assess the full extent of structural issues and provide honest recommendations about whether repair or replacement is the right choice.

Warning Sign #5: Daylight Visible Through Roof Boards

Here's a simple test: on a sunny day, go into your attic and turn off any lights. Can you see pinpricks of daylight coming through the roof?

What This Tells You

If light can get through your roof, so can water, cold air, and pests. Visible light indicates:

• Gaps in sheathing

• Missing or damaged shingles

• Failed flashing around vents or chimneys

• Structural separation

The Insulation Connection

While you're in the attic checking for light, assess your insulation:

• Is it compressed or damaged?

• Does it show water stains?

• Is it adequate for Iowa's climate? (Recommended: R-38 to R-60 for attic insulation)

Poor attic insulation compounds roofing problems by allowing heat to escape in winter, which contributes to ice dam formation. When you replace your roof, it's the perfect time to upgrade insulation and ventilation.

Just as quality SoftLite windows improve your home's energy efficiency through superior insulation, a properly installed roof with adequate ventilation protects your home while reducing energy costs.

Warning Sign #6: Neighbors Are Getting New Roofs

This might seem like an odd warning sign, but it's actually quite practical—especially in established Des Moines neighborhoods where homes were built around the same time.

Why the Neighbor Factor Matters

If you're noticing multiple neighbors replacing their roofs, consider:

Shared timeline: Homes built in the same development likely have roofs of similar age

• If your neighbors' 20-year-old roofs are failing, yours probably isn't far behind

• You all experienced the same weather events and climate stress

Storm damage indicators: Recent severe weather may have damaged multiple roofs

• Spring 2024's hail storms affected large areas of Des Moines

• If neighbors are filing insurance claims, you should inspect your roof too

• Hail damage isn't always immediately obvious but progressively worsens

Contractor availability: When multiple homeowners need roofs in your area

• Quality contractors book up quickly during peak season

• Waiting might mean settling for less experienced crews or delaying until next year

• Early planning gets you better scheduling options

The Proactive Approach

If several neighbors are replacing roofs and yours is a similar age, schedule a professional inspection now rather than waiting for problems to appear. This lets you:

• Plan the investment on your timeline

• Potentially coordinate with neighbors for better pricing

• Avoid emergency replacement during Iowa's harsh winter or busy spring season

• Choose your contractor carefully rather than scrambling during a crisis

The Cost of Waiting vs. Replacing Proactively

Many Des Moines homeowners ask: "If my roof isn't actively leaking, can I wait another year or two?"

Here's the math that might change your mind:

Emergency Replacement Costs More

Proactive replacement on your schedule:

• Time to get multiple quotes and choose the best contractor

• Flexibility to wait for ideal weather conditions

• Ability to plan financing and budget accordingly

• Control over material selection and upgrade options

Emergency replacement during a crisis:

• Limited contractor availability (often paying premium rates)

• Pressure to make quick decisions

• Potential additional costs for temporary repairs or tarping

• Risk of choosing lower-quality contractor due to urgency

The Hidden Cost of Water Damage

A failing roof doesn't just need replacement—it causes collateral damage:

Potential additional expenses from delaying:

• Roof decking replacement: $1,000-$3,000+

• Rafter or truss repairs: $500-$2,000 per section

• Insulation replacement: $1,500-$3,000

• Interior ceiling/wall repairs: $2,000-$5,000

• Mold remediation: $1,000-$10,000+

Example scenario: A $12,000 roof replacement delayed by two years might become a $18,000-$20,000 project once you add in all the water damage repairs.

Iowa Weather Won't Wait

Unlike some climates where roof problems develop slowly, Iowa's weather accelerates deterioration:

• One bad hail storm can take a marginal roof from "needs replacement soon" to "emergency"

• A single winter of ice dams can cause extensive hidden damage

• Heavy spring rains exploit small vulnerabilities and create big problems
