At HI Roofing, we are adept in the installation and the maintenance of residential and commercial roofing. We also provide installation and repair services for flat roofs. Having a solid flat roof that is in good repair helps prevent leaks from standing water or pests from intruding. Whether your flat roof requires a new installation or repair, we can help you determine the best options for your building. From tar and gravel (built up roofing) to cold process, we have the knowledge you need for your project. We have served the Greater Toronto Area since 1996. Call us today for an estimate.
