The Most Expensive Exterior Mistakes Homeowners Make in Summer

(And How to Avoid Them)

The biggest exterior mistakes homeowners make in summer are simple: they ignore small problems that don’t seem urgent.

In Central Minnesota, summer brings heat, storms, and heavy rain. Those conditions don’t create problems—they expose and accelerate the ones already there. What starts as a minor issue in June often becomes a major repair by late summer.

The most common mistakes we see include:

• Ignoring early roof wear after storms
• Missing or improperly installed flashing
• Letting failing gutters continue to overflow
• Waiting too long to address siding issues
• Hiring the wrong contractor during peak season 

If you suspect that your exterior may need repairs or replacement, work with a local company that does the job right. Contact BD Exteriors at (320) 229-2855 or use our online form to get started!

What Are the Most Expensive Exterior Mistakes Homeowners Make in Summer?

Mistake #1: Ignoring Minor Roof Damage After Spring Storms

Most roofs don’t fail all at once. They start with small issues:

  • Slight shingle lifting
  • Granule loss
  • Minor flashing gaps

From the ground, everything can look fine. But once summer storms roll through, those small issues get worse fast.

What happens if you wait:

  • Water works its way under shingles
  • Roof decking begins to break down
  • What could have been a repair turns into a larger project

What to do instead:

Have your roof checked early in the season—before repeated storms compound the damage.

Mistake #2: Missing or Improper Kick-Out Flashing

This is one of the most overlooked—and most expensive—problems we see. Most homeowners have never heard of kick-out flashing, but it’s critical where your roof meets a vertical wall.

Its job is simple: direct water away from the siding, or even better, direct it into the gutter. When it’s missing or installed incorrectly, water doesn’t get pushed away; instead, it gets pushed behind the siding. That leads to:

  • Water running behind siding instead of draining properly
  • Hidden moisture buildup inside the wall
  • Rotting wood and structural damage
  • Staining and premature siding failure

The problem is, you usually don’t notice it until the damage is already significant.

What to do instead:

  • Ensure proper flashing is installed during roofing or siding work
  • Pay attention to areas where rooflines meet walls
  • Address it early if you see repeated staining or moisture issues

Mistake #3: Ignoring Chimney and Roof Flashing Issues

One of the most common—and most expensive—problems we see is around chimneys and roof penetrations. From the ground, everything can look fine. But up close, we often find:

  • Cracked chimney crowns
  • Deteriorating mortar joints
  • Rusted or lifting flashing
  • Poor sealing where the roof meets the chimney

These areas are some of the most vulnerable points on your roof. And once water finds its way in, it doesn’t take long for problems to develop inside the home.

What happens if you wait:

  • Water leaking into the attic or ceiling
  • Interior staining and drywall damage
  • Rotting roof decking around the chimney
  • Mold and moisture issues over time

The tricky part is that these leaks are often slow and go unnoticed until the damage becomes obvious.

What to do instead:

  • Inspect chimney and flashing areas regularly—especially after winter
  • Address cracked mortar or deteriorating chimney structure early
  • Ensure flashing is properly installed and sealed during any roof work
  • Don’t ignore small leaks or staining near chimney areas

Mistake #4: Waiting Too Long to Address Siding Issues

Siding problems don’t stay the same in summer—they get worse. Heat, moisture, and repeated storms can accelerate damage quickly. Common signs include:

  • Loose or warped panels
  • Cracking or separation
  • Moisture getting behind the siding

What happens if you wait:

  • Water intrusion behind siding
  • Rot and structural issues
  • Increased repair scope

What to do instead:

Address siding concerns early before moisture has time to spread.

Mistake #5: Hiring Based on Price Instead of Long-Term Quality

Summer is peak season—and that brings more options, not all of them good. Some homeowners make decisions based on:

  • Lowest bid
  • Fast availability
  • High-pressure sales

That often leads to shortcuts in installation.

What these can result in:

  • Improper flashing
  • Poor ventilation
  • Shortened lifespan of materials

What to do instead:

Choose a contractor who understands Minnesota conditions and installs complete systems—not just shingles or siding.

Why Summer Is When Problems Get Expensive

Summer doesn’t create issues—it accelerates them. Between heat, rain, and storm cycles, small problems don’t stay small.

The earlier they’re addressed, the more options you have—and the less they typically cost to fix.

How to Avoid These Mistakes

The best approach is straightforward:

  • Don’t ignore small warning signs
  • Address issues early in the season
  • Focus on proper installation—not shortcuts
  • Work with a contractor who understands local conditions

Most costly repairs we see could have been prevented with earlier action.
