This company left my car covered in dust and dirt. I didnt even get an apology. Just an offer to wait for 10 minutes during my busy day for someone to come with an air blower to blow it all off. They also leave the work area a mess after leaving site.

To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.

4. How to check if a roofing company is legit?
+-

Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.

5. How to choose a roofing company?
+-

When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.

6. How do you know if your roofing contractor is ripping you off?
+-

Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
