Roofing Lic. #104.016085

Roofing is the flagship enterprise of Promax Construction.  Promax Construction is a licensed roofing company in the state of Illinois.  Requirements for a roofing license include proof of insurance and the passing of rigorous standards and testing.  Before hiring a roofing company, always make sure they are licensed and insured.  A roofer without the proper insurance can be a serious liability for you and your family.  Homeowners are liable if an unlicensed, uninsured roofer is hurt on the job.  If the job is botched, the roofer does not have liability insurance to cover the loss.  Promax offers the guarantee of a big company and the service of a boutique.
