5 Common Costly Roofing Mistakes Every Homeowner Should Know

Your roof protects everything under it, your family, belongings, and the structure of your home. But one wrong move during repairs, replacements, or maintenance can lead to expensive consequences.

At Mile High Renovation, we’ve seen the full range of roofing mistakes made by both DIYers and inexperienced contractors. If you're planning a new roof installation or just trying to maintain the one you have, here are the 5 most common (and costly) roofing mistakes to avoid.

1. Ignoring Early Warning Signs of Roof Damage

That small stain on the ceiling or a missing shingle might not seem urgent, but it could be a sign of a larger issue. Waiting too long to address problems can lead to:

  • Water leaks and interior damage

  • Mold and mildew growth

  • Structural weakening of the roof deck

What to do instead: Schedule regular roof inspections, especially after hailstorms or high winds, which are common in Colorado. Spotting damage early can save you thousands in repairs.

2. Poor Ventilation

A well-ventilated roof allows hot air and moisture to escape from the attic. Without proper airflow, you risk:

  • Overheating your attic space

  • Ice dams forming in winter

  • Premature aging of your shingles

  • Mold growth

What to do instead: Make sure your roofing contractor includes proper ventilation as part of your installation or replacement. This is especially critical in Colorado’s varied climate.

3. Choosing the Wrong Roofing Material for Colorado's Climate

Not all roofing materials are built for the hail, snow, and sun exposure we experience here in Colorado. Using low-quality or inappropriate materials can result in:

  • Higher energy bills

  • Frequent repairs

  • Poor resistance to weather damage

What to do instead: Talk to a local roofing expert about the best roofing material for your home. Options like impact-resistant asphalt shingles or metal roofing are great choices for our region.

4. Hiring Unlicensed or Inexperienced Contractors

Going with the cheapest bid might save you money upfront, but hiring someone who cuts corners or lacks proper licensing can end up costing more in the long run.

Common signs of poor workmanship:

  • Shingles not aligned correctly

  • Improper flashing around chimneys and vents

  • Missing drip edge or underlayment

  • No warranty provided

What to do instead: Always hire a licensed, insured, and experienced contractor. At Mile High Renovation, we provide detailed estimates, quality craftsmanship, and full warranty coverage.

5. Failing to Get the Right Permits

Skipping permits to speed up a project can lead to code violations, fines, and complications when you try to sell your home. Every city and county in Colorado has its own roofing requirements.

What to do instead: Make sure your roofing contractor handles all local permitting and code compliance before the project begins. We manage this for every job to ensure your roof is safe, legal, and up to code.

Final Thoughts

A new roof is a major investment, and avoiding these common mistakes is the best way to protect that investment. From picking the right materials to hiring the right team, every decision matters.
