Even if you use top quality tiles, if you use inexperienced , unlicensed or amateur contractors to install them, you’ll be sorry later. Make sure you’re hiring a reliable, professional, properly licensed and insured company like this one to do the job. This goes for any repairs you need, also. Don’t hire a handyman or someone that will do a cheap job for you to make any repairs on your roof. Make sure , again, that they’re a professional roofing contractor.
