Ask For Referrals: Talk to friends, family, and neighbors who have recently had their roofs done. They may be able to recommend a good roofing contractor.

Check Online Reviews: Look for reviews of roofing contractors on websites like Google, Yelp, and Angie's List. Be sure to read both positive and negative reviews to get a well-rounded view of the contractor's work.

Verify Licenses And Insurance: Make sure the roofing contractor you are considering is licensed and insured. You can check this information with your state's licensing board or with the contractor directly.

Get Multiple Estimates: Contact several roofing contractors and ask for estimates. Compare the estimates to ensure you are getting a fair price for the work that will be done.

Check for Certifications: Look for roofing contractors who have certifications from organizations like the National Roofing Contractors Association (NRCA) or the Roofing Contractors Association of Texas (RCAT).

Note: Verify their contract details, warranty, and insurance policy. By following these steps, you will be able to find a reliable roofer who can do the job safely and efficiently.

To avoid getting scammed by a roofer, it is important to do your research and carefully vet any potential contractors before hiring them. Here are a few steps you can take to protect yourself:

Get multiple estimates from different roofing companies. This will give you a better idea of what a fair price should be and can help you identify any companies that may be charging too much or too little.

Check the company's credentials. Make sure the roofing company is licensed, insured, and has a good reputation. You can do this by checking with the Better Business Bureau, or by asking for references from past customers.

Be wary of door-to-door salesmen. Scammers often try to take advantage of homeowners by offering "deals" that are too good to be true. Don't sign any contracts or make any payments without doing your research first.

Get everything in writing. Make sure you have a detailed contract that outlines the scope of work, the materials that will be used, the total cost of the project, and the timeline for completion.

Don't pay upfront. Reputable roofing companies will not ask for a large deposit or full payment before the work is completed.

By following these steps, you can help ensure that you are working with a reputable and trustworthy roofing contractor.

It is generally recommended to tip roofers between $20-$50, or 10-15% of the total cost of the job. However, the amount of the tip can vary depending on the quality of the work and the level of customer satisfaction. Ultimately, the decision of how much to tip is up to the individual.
