How do you know which roofing contractor to trust? Your roof is one of the most important parts of your home, and hiring the wrong company can lead to costly mistakes. With so many options out there, it’s easy to feel overwhelmed. After all, a new roof is a big investment, and you want to be sure you’re choosing a roofing contractor who will do the job right.
A reliable roofing company should have the right credentials, a solid reputation, and a commitment to quality workmanship. But how can you tell the difference between a trustworthy contractor and one that will cut corners?
To help you make the right choice, here are eight key things to look for in a roofing contractor. If you’re in Phoenix, these roofing contractor tips will be especially useful, as we’ll cover some local factors to keep in mind.

1. Check for Licensing and Insurance
One of the first things to ask any roofing contractor is whether they are licensed and insured. A professional roofing company should have the proper credentials to operate in your area and the necessary insurance to protect you and their workers.
Why does this matter?
- A licensed contractor follows industry regulations and best practices.
- General liability insurance protects your home if any damage occurs during the project.
- Workers’ compensation insurance covers the roofing crew in case of injuries, so you’re not held responsible.
At TSM Roofing LLC, we are fully licensed and insured, so our customers never have to worry about liability issues.
2. Look for Experience and a Strong Reputation
Experience matters when it comes to roofing. A company that’s been in business for years has likely seen it all and knows how to handle different roofing challenges. But experience alone isn’t enough—you also want a contractor with a solid reputation.
How do you check this?
- Read customer reviews on Google, Yelp, or the Better Business Bureau.
- Ask for local references to see completed work in your area.
- Find out how long they’ve been in business—contractors with a long track record are more likely to stand behind their work.
With nearly a decade of experience, TSM Roofing LLC has built a reputation for quality workmanship and top-tier customer service.
3. Verify Manufacturer Certifications
A great roofing contractor doesn’t just install roofs—they are trained and certified by top manufacturers. Roofing certifications mean the contractor has met high industry standards and is qualified to install specific roofing materials.
Some of the most respected certifications include:
- Owens Corning Platinum Preferred Contractor
- GAF Master Elite Certification
- TRI (Tile Roofing Industry Alliance) Certified
These certifications show that the contractor is experienced, knowledgeable, and able to provide manufacturer-backed warranties. TSM Roofing LLC is proud to be an Owens Corning Platinum Preferred Contractor, meaning we offer some of the best roofing materials and warranties in the industry.
4. Ask for a Detailed Estimate and Contract
A professional roofing company should provide a clear, written estimate before starting any work. If a contractor gives you a vague quote or pressures you into signing a contract on the spot, that’s a red flag.
A good estimate should include:
- A breakdown of costs, including materials and labor
- The project timeline, so you know when the work will be completed
- Warranty details for both materials and workmanship
At TSM Roofing LLC, we believe in complete transparency. Our estimates are detailed, easy to understand, and free of hidden fees.
5. Understand Their Warranty Offerings
A new roof is a big investment, and you want to be sure it’s protected. A quality roofing contractor should offer both manufacturer and workmanship warranties.
- A manufacturer’s warranty covers defects in roofing materials.
- A workmanship warranty ensures the installation was done correctly.
We offer lifetime manufacturer warranties and up to 7-year workmanship warranties, giving our customers peace of mind that their roof is built to last.
6. Choose a Local Roofing Expert
Hiring a local roofing contractor has several advantages. Not only are they familiar with the area’s climate, but they also understand local building codes and permit requirements.
Why is this important?
- Local roofers understand the impact of Arizona’s extreme heat, monsoons, and dust storms on roofing materials.
- They can respond quickly to repair requests or emergency services.
- A company rooted in the community is more likely to stand behind its work.
As a locally owned and operated company, TSM Roofing LLC knows the roofing challenges specific to Phoenix and provides tailored solutions to keep homes protected.

7. Pay Attention to Communication and Professionalism
Communication is key when working with a roofing contractor. From the initial inspection to the final cleanup, a good contractor should keep you informed throughout the process.
What should you expect?
- Prompt responses to phone calls, emails, and questions
- Clear explanations of materials, costs, and timelines
- Professional behavior from the entire crew
At TSM Roofing LLC, we prioritize customer service. We’re always available to answer your questions and provide updates on your project.
8. Find Out if They Offer Emergency Services
Arizona’s weather can be unpredictable, with high winds, monsoons, and hail causing sudden roof damage. If your roof is leaking or missing shingles after a storm, you need a contractor who provides emergency roofing services.
What should emergency services include?
- 24/7 availability for urgent repairs
- Tarping services to prevent further damage
- Help with insurance claims if the damage is covered by your policy
We offer 24/7 emergency roofing services, including storm damage inspections and temporary repairs, to help homeowners protect their properties.
