5 Common Mistakes Homeowners Make When Hiring a Roofer

March 6, 2025

Finding a reliable roofing contractor is one of the most important steps in protecting your home from weather damage, leaks, and structural deterioration. A poor roofing job can lead to costly repairs and even safety hazards. At Roof Repair Thousand Oaks, we’ve seen many homeowners fall victim to unreliable contractors, leading to subpar installations and expensive fixes. To ensure you choose a qualified professional, avoid these five common mistakes when hiring a roofer.


1. Failing to Research the Contractor

Choosing the first roofer you come across or selecting one based solely on price can lead to serious problems. Unqualified contractors often cut corners, use low-quality materials, or leave jobs unfinished.

How to Avoid This Mistake:

  • Check Reviews and Ratings – Look for customer feedback on platforms like Google and the Better Business Bureau (BBB).
  • Ask for a Portfolio – A reputable roofer should provide photos of past work.
  • Request References – Speaking to past clients can give you a better idea of what to expect.

Fact: According to the National Roofing Contractors Association (NRCA), nearly 50% of roof repairs result from poor installation by unqualified contractors.


2. Ignoring Licensing and Insurance

A legitimate roofing company must be licensed, bonded, and insured. Hiring an unlicensed contractor puts you at risk of poor workmanship and legal complications. If an uninsured worker is injured on your property, you could be held liable for medical costs.

How to Avoid This Mistake:

  • Verify Licensing – Ask for a valid state license number and check it with local authorities.
  • Request Proof of Insurance – Ensure the company has both liability insurance and worker’s compensation coverage.
  • Confirm Bonding – A bonded roofer provides financial protection if the project isn’t completed as agreed.

3. Accepting the Lowest Bid Without Question

While it’s tempting to choose the cheapest option, extremely low bids often indicate poor-quality materials, unskilled labor, or hidden fees. Some contractors offer a low price upfront but later add unexpected costs, leaving homeowners with no choice but to pay.

How to Avoid This Mistake:

  • Get Multiple Estimates – Compare quotes from at least three different contractors.
  • Ask About Materials – Ensure that the roofer is using durable, high-quality products.
  • Understand the Full Cost – Request a detailed breakdown of pricing to avoid hidden fees.

Fact: Studies show that choosing a low-cost roofing contractor often leads to repairs within five years, compared to 15–25 years with a high-quality installation.


4. Not Getting a Written Contract

A verbal agreement is never enough when it comes to roofing work. Without a contract, homeowners have no proof of agreed-upon services, costs, and warranties. Some contractors deliberately avoid putting things in writing to leave room for price changes or incomplete work.

How to Avoid This Mistake:

  • Ensure All Details Are Documented – The contract should include pricing, project timelines, materials, and warranties.
  • Review the Warranty – Understand what is covered and for how long.
  • Never Pay in Full Upfront – A reasonable deposit is normal, but avoid contractors who demand full payment before starting.

5. Overlooking Communication and Professionalism

A contractor’s communication style can tell you a lot about how they’ll handle your project. Unresponsive, vague, or pushy contractors are often unreliable and difficult to work with.

How to Avoid This Mistake:

  • Look for Prompt Responses – A professional roofer should answer calls and emails in a timely manner.
  • Ask Questions – A good contractor will provide clear, knowledgeable answers.
  • Pay Attention to Attitude – If a contractor is dismissive or evasive before you hire them, they’re unlikely to be reliable once the project begins.
