When it comes to protecting your home, your roof is your first line of defense against the elements. So when repairs or replacements are needed, hiring the right professional is essential. Unfortunately, many homeowners make costly errors during the selection process. If you’re looking for a residential roofing contractor in Andover MN, avoiding the following mistakes can save you time, money, and a lot of headaches.

1. Failing to Verify Licensing and Insurance

One of the most common—and potentially dangerous—mistakes homeowners make is hiring a roofing contractor without verifying their credentials. A licensed residential roofing contractor in Andover MN will meet the necessary state and local requirements to perform roofing work legally and professionally.

Even more important is checking for insurance. Proper liability and workers' compensation coverage protects you if someone is injured on your property or if any accidental damage occurs during the job.

What to Do:

Ask for proof of both licensing and insurance. Reputable contractors will be happy to provide documentation.

2. Choosing Based on Price Alone

Everyone wants to save money, but going with the cheapest quote can lead to poor workmanship, low-quality materials, and even incomplete projects. Remember, you often get what you pay for—especially in roofing.

Choosing the lowest bidder may seem like a deal at first, but it could result in costly repairs or full replacement down the line.

What to Do:

Compare more than just the price. Look at the scope of work, materials used, warranties offered, and the company’s reputation.

3. Not Checking Local References or Reviews

You wouldn’t hire someone to work inside your home without doing a background check—your roof should be no different. Many homeowners make the mistake of hiring a contractor based on flashy marketing or a quick quote without digging into their past performance.

Reviews and references offer valuable insights into how a contractor operates and treats their customers.

What to Do:

Ask your potential residential roofing contractor in Andover MN for at least three local references. Then, follow up. Also, check online reviews on Google, BBB, and local Facebook community groups.

4. Overlooking Manufacturer Certifications

Did you know that some roofing contractors are certified by leading roofing manufacturers? This isn’t just a marketing perk—it often means they’ve received advanced training and can offer extended warranties.

Hiring a contractor without these certifications might limit your warranty options and raise questions about their qualifications.

What to Do:

Ask if the contractor is certified by any major manufacturers like GAF, Owens Corning, or CertainTeed. These certifications are a strong signal of professionalism and product knowledge.

5. Ignoring the Warranty Details

Not all warranties are created equal. Some homeowners make the mistake of assuming that every roofing job comes with long-term protection. Others don’t realize that warranties for materials and workmanship are separate.

If your residential roofing contractor in Andover MN offers no workmanship warranty—or only a vague verbal promise—you could be on your own if problems arise later.

What to Do:

Ask for written copies of both material and labor warranties. Understand what is covered, for how long, and what could void the warranty.

6. Skipping the Written Contract

Verbal agreements can lead to miscommunication, misunderstandings, or outright fraud. Unfortunately, some homeowners agree to roofing jobs with only a handshake deal—only to run into issues when the contractor fails to follow through.

What to Do:

Always insist on a written contract that outlines the project scope, materials, timeline, payment terms, and warranty coverage. It protects both you and the contractor and ensures you're on the same page.

7. Not Asking About Permits and Cleanup

Many roofing projects in Andover MN require permits to comply with local building codes. Some contractors may try to skip this step to cut corners—which can land you in legal or safety trouble later.

Additionally, some homeowners forget to ask how cleanup will be handled. Leftover nails, shingles, and debris can damage your yard or pose a safety risk.

What to Do:

Ask your residential roofing contractor in Andover MN if they handle permits and inspections. Also, ask about their post-job cleanup process and whether they use magnetic tools to collect nails.

Final Thoughts

Hiring the right residential roofing contractor in Andover MN isn’t just about fixing or replacing a roof—it’s about protecting your home, family, and finances. By avoiding these seven common mistakes, you’ll be much better prepared to choose a trustworthy, experienced contractor who delivers quality workmanship and long-term value. Don’t rush the decision. Do your research, ask smart questions, and work with a contractor who prioritizes honesty, safety, and customer satisfaction.
